    Structural G Limits
    Before 4.10 patch all aircraft in IL2 have a single fixed Structural G limit of +13.5G. It only
    really becomes an issue with aircraft with exceptionally light elevators such as the P-51. Pull
    more than +13.5G and you loose your wings. The real life situation is a little more
    complicated. Real aircraft are designed with an Ultimate load and In Service design load. Both
    are for a defined configuration and weight.
    In Service load is the typical G available to the pilot. As long as this the G is not exceeded then
    no aircraft damage will occur. Exceed the In service G limit then damage of varying degrees
    may occur like bent airframes etc. Exceed the Ultimate load then severe damage will occur
    typically resulting in structural failure like wings coming off etc. Typically a safety factor of 1.5
    is used. So fighter plane with a design In service G limit of say +8G will have an Ultimate load
    of +12G. As external stores and or weight is increased above the design weight, both G limits
    reduce accordingly. Reduce weight (by dropping bombs or burning fuel etc.) and your G limits
    increase. Bomber and Transport aircraft have G limits much lower than fighters.
    So if you abuse the limits you damage the aircraft. Once damaged then its structural integrity
    is reduced so the ultimate load reduces as well. In other words keep bending the airframe and
    you will eventually weaken it to the point that very little extra G is required to induce
    structural failure. A bent airframe won’t perform as well either.
    How does this work in game? You take your stock standard Fighter Mk 1 with default
    armament +100% Fuel your limits are +8G/+12G. You add 2 x 500lbs bombs. Your limits now
    reduce to 5G/8G. So prior to the target you need to be a little more careful with your plane.
    Lets say pre target you pull + 6G, you have exceeded the “in service” limit, you will hear a
    damage sound cue and suffer a slight aerodynamic penalty. In addition your G limits have now
    reduced to say 5G/6G. Bust these again and further aerodynamic penalties and further
    reductions will apply. You progress to the target and release your bombs. Since the weight is
    reduced your limits will increase but since you already bent the airframe you won’t get back
    your original limits. You might then get say +8G/+10G. As you can see if you keep abusing the
    limits you will end with a very weakened airframe.
    In the case of heavy bombers, G limits will prevent any real aerobatic maneuvers. You will still
    be able to evade quite well but you wont be able to BFM with plane like the A-20 anymore.
    Bombers will be just that: Bombers.
    G Indications
    When the speedbar is enabled an indication of proximity to the Service limit is provided. When
    you get within 25% of the current Service limit a "G" will be displayed on the top of the
    speedbar. As you get to within 10% of the current Service limit the "G" will begin to flash. The
    process being reversed as you reduce the G. No G cueing is provided if Speed bar is
    deselected.
    If players use No Cockpit View than direct readout of G is provided. Number is white while G's
    are above 0, when you get within 25% of the current Service limit number turns to red. Below
    0G,number is black.
    Quick Mission Builder (QMB)
    Additional Flights
    It is now possible to have 16 flights in QMB (8 vs. 8). On the first page of QMB are first 4
    friendly and 4 enemy flights. The player's flight is the first friendly flight on the first page.
    Additional flights can be reached by clicking on the "Next" button at the bottom.
    5 / 35
    Statistics Page
    On the second QMB page you will notice a new button called "Stats". It leads to the QMB
    statistics page. There are all sorts of statistical categories for you to enjoy. Statistics are now
    kept for your last flown QMB mission, last played session (series of missions you play before
    you exit the game) and, of course, statistics of your whole career. There is also a "Reset Stats"
    button at the bottom.
    Plane Lists
    At the bottom right part of the first QMB page there is a Plane List drop down list. There are
    two planes lists immediately available: Standard and Alphabetical. When the first one is
    selected all planes are ordered as usual. When you select Alphabetical list planes are sorted
    alphabetically. You can also create two additional plane lists on your own: QMBair_2.ini and
    QMBair_3.ini. Place them in the Missions/Quick/ folder. The structure of the files must look
    something like this:
    [AIR]
    BeaufighterMk21
    BlenheimMkIV
    BI-1
    BI-6
    BuffaloMkI
    You can have planes you like in those lists and only those will appear in the plane drop down
    menus. Also you can add the line DumpPlaneList=1 to [QMB] section and the game will dump
    the list of all planes in correct format to Missions/Quick/FullPlaneList.dump file.
    Adding more Missions
    You can also create new missions for QMB. Your favorite map is not in? No problem, add it
    yourself. First you need to create the mission in FMB and make 8 flights for each side. Use
    default squadrons only. Then you have to name them properly according to certain rules. First
    make a new folder in Missions/Quick/ folder. Place the mission there and make sure that the
    first part of the mission name is exactly the same as the name of the folder you created. The
    second part of the mission filename determines the army of the player (Red or Blue). The next
    part determines the mission type (Airbase, Armor, Bridge, NoneN, NoneA, NoneD or
    Scramble). The last part are two numbers for stock missions, but can be practically anything
    (like DaidalosCoolestMissionsEver00001). If you have several missions which only differ in the
    last part of the filename (meaning that map, army and mission type are the same), QMB will
    pick one randomly when the mission is started by the player.
    If you plan to share your missions with others, it's best to use internal map name which is
    automatically translated to other localizations. Also it would be nice to use distinctive last part
    of the filename (like Daidalos... example above), so users can combine your missions with
    other authors for some variety.
    There is nothing stopping you from making fake missions, for example mission named:
    KievBlueArmorCoolAppendix99.mis which actually loads Norway map with None target and
    player at disadvantage. The GUI elements in QMB are filled according to mission filename, not
    according to what is actually written in the mission file.
    Reset
    There is a Reset button on the first QMB page which resets all flights to default values (number
    of planes, selected planes and loadouts). Also, each time you exit the game, mission settings
    are stored and loaded automatically when you start Il-2 another time.
    6 / 35
    Full Mission Builder (FMB)
    Selecting Multiple Objects
    To select/deselect multiple objects in FMB you need to have these commands enabled in your
    conf.ini. Check the [HotKey builder] section for these two commands:
    Alt MouseLeft=select+
    Alt MouseRight=select-
    Hold down the [ALT] key and left mouse button press and 'draw' a rectangle around some
    ground objects. All appropriate objects are grouped into a single selection (multiselection). Do
    this again on another group of objects and they are added to the multiselection. Naturally, by
    holding down the [ALT] key and right mouse button you can remove objects from the selection
    by 'drawing' a rectangle around them. Not all objects can be added to the multiselection. Here
    is a list of those than can:
    • Artillery
    • Stationary Armor
    • Stationary Objects
    • Stationary Aircraft
    • Stationary Ships
    • Rocket
    • Objects
    • Static Camera
    If you want to unselect all objects you can do that through Edit -&gt; Unselect All option in the
    menu.
    Cut / Copy / Paste / Delete / Move
    Add these commands to your conf.ini
    Ctrl C=mis_copy
    Ctrl X=mis_cut
    Ctrl V=mis_paste
    to be able to perform these commands. When you have some objects in multiselection execute
    the copy or cut command. Click somewhere on the map and then paste them. You can paste
    them multiple times. You can also delete the entire multiselection by pressing the [DELETE]
    button on your keyboard. You can also move your multiselection. First add some objects to
    multiselection. Then press and hold left mouse button above one of the objects in
    multiselection. Still holding the left mouse button move your mouse cursor to the desired
    location on the map.
    Rotation
    When you have created a multiselection, you can rotate the whole group of objects. Left click
    somewhere on the map and use your numpad keys to rotate the group of objects around the
    mouse position. There are two types of rotation: when individual objects change their
    orientation with respect to the world coordinates (when the option Edit -&gt; Rotate Object is
    checked) and when individual objects maintain their original orientation.
    Snap
    Snap allows you to move objects along a grid. This helps placing objects with equal distance to
    each other. This option can be reached through View -&gt; Snap. Make sure that the option is
    checked. You can also set the 'snap step'. Smaller step makes the grid where objects can be
    placed denser.
    7 / 35
    Load / Save dialog box
    You can change the default size of the Load/Save dialog box which is useful if you have many
    missions saved. Open the bldconf.ini file and set the values of defFullDX and defFullDY
    variables to suit your needs.
    Mission Date
    Clicking on the Configure -&gt; Conditions you will notice that the dialog box has new tab "Date".
    You can set the precise day, month and year of your mission there.
    Wind
    “Weather” tab in the Configure -&gt; Conditions dialog box now has new set of parameters that
    adjust the wind in the mission. It's possible to set Wind direction, Wind velocity, Gust and
    Turbulence. Wind direction is as per aviation standards and is entered as where the wind is
    blowing from. A westerly wind is entered as 270.
    Multi-throttle/prop support and radiator axis
    4.10 patch introduces following new axis for HOTAS controls:
    • Engine 1 Power
    • Engine 2 Power
    • Engine 3 Power
    • Engine 4 Power
    • Engine 1 Prop Pitch
    • Engine 2 Prop Pitch
    • Engine 3 Prop Pitch
    • Engine 4 Prop Pitch
    These directly control their assigned engines.
    • Radiator
    Axis controlling radiator opening.
    • Zoom
    changes field of view
    The player needs to map these axis before multi-throttle/prop for separate engines work. For
    compatibility reasons Team Daidalos decided that all existing controls should stay in place and
    work in parallel to new ones. If you have for example both Power and Engine 1 Power mapped
    and engine 1 selected, both axes will fight together and last input will be used every time.
    Radiator is same except there are axis and key interacting in this fashion.
    Automatic radiators: you still have to use the radiator key to activate auto mode. There is
    special part of Radiator axis travel (approx. above 80%), any movement in this range will not
    switch radiator out of automatic mode.
    Advanced joystick profiles
    General Concept
    Previously you were adjusting sensitivity of your Joystick primary axes. Team Daidalos
    changed this so that you actually adjust response of your controls. This means that any control
    listed in HOTAS section of Controls menu can be adjusted. All you have to do is assign
    something to the desired control and it will appear in the Joystick menu top left drop down list.
    8 / 35
    Controls Response
    Choosing one of the primary controls (ailerons, elevator and rudder) you won't see much
    difference from the previous method. Ailerons and elevator responses are shown in the big
    square box, while the rudder response is shown in the bottom horizontal rectangle. As usual
    you can adjust sensitivity, dead band and filtering. If you choose any other control (like Power
    or Prop Pitch) additional vertical response rectangle will be shown on the right. You can adjust
    sensitivity, dead band and filtering for that control also.
    Symmetrical Switch
    Some of the control axes behave symmetrically (or mirrored). For example you probably want
    your ailerons sensitivity curve to be the same if you push your joystick to the left and right.
    But it doesn't make much sense to do that for Power control, for example. That's where the
    Symmetrical switch comes into play. Turn it off and the sensitivity will be applied over the
    whole range of values without trying to make them symmetrical. In other words, ailerons and
    similar controls have values from -100% to 100% and you want the sensitivity to be mirrored
    around zero value. Power, on the other hand, is more logically described as a control with
    values ranging from 0% to 100%. You probably want this control to have different sensitivity
    response over the whole range.
    Joystick Profile
    As before you can use 4 different Joysticks (or similar devices) to control your plane in IL-2.
    But in addition to that, now you can have 4 different Joystick profiles stored in IL-2. Please
    don't confuse 4 different physical Joysticks with 4 different Joystick profiles. What's this all
    about? Well you can adjust your sensitivity curves to suit TnB fighter and save it as your first
    profile (click Save button).
    If you find yourself flying a BnZ fighter, those settings might not suit you. No problem, switch
    to a different profile (top drop down menu and click Load) and use you BnZ fighter settings. As
    there are 4 profiles available, you can use one for bombers or ground-attack planes. It's all up
    to you to make sensitivity profiles for your specific needs. You might find this feature rather
    useful considering the new G-limits in 4.10 patch.
    Changing Joystick Profile
    Joystick setup menu can now also be reached with a button from Air Arming screen. Why from
    there? Well, this menu appears in every gameplay type: single, dogfight, coop. That means
    that you can switch to a different Joystick profile (or even adjust it) without disconnecting from
    the server. Switching from Red to Blue or from Fighter to Bomber has never been easier.
    Engine Reliability Difficulty Option
    All engines have now small chance of failure at every moment of flight. Probability depends on
    power generated by engine and its RPM (more power, bigger chance for an engine to fail). Not
    every failure is catastrophic, some of them just reduce power, but if its not your lucky day
    then you might end up with a problem. Purpose of this feature is to give a reason to be easy
    on engine, not to follow historical failure rates of specific engines. This can be turned off in
    difficulty settings.
    Improved Pilot Damage Difficulty Option
    With this difficulty option turned on, damage to the pilot is more severe. Being hit is something
    that has very serious consequences now. That apply to AI pilots and gunners too, it is much
    easier to kill them. You will have to adjust your tactics to accommodate this change, avoid
    being hit at all costs and when on attack, aim at the cockpit, especially if you are in plane
    armed with light machine guns only. Against bombers, aim at gunners first to disable them,
    you are better protected and you have more guns than them.
    As you can imagine, if you can get killed easier, than you can get wounded easier too. In
    9 / 35
    addition, there are more variations in wounds, you can get hit in the arm or leg with a
    corresponding loss of control over the plane. To make things even more complicated, some
    wounds will cause bleeding and you can bleed to death unless you reach home in time.
    Gunners ability to shoot is also reduced when they get wounded.
    New Flyable Planes
    Henschel Hs 129
    The Henschel Hs 129 was developed by engineer Friedrich Nicholaus in response to a 1937
    request by the German Air Ministry for a small, heavily armored ground attack/support aircraft
    equipped with a minimum of two 20 mm cannon and two rifle caliber machine guns. Nicholaus'
    design stressed pilot survivability. The cockpit was surrounded by an armor plated "bathtub" of
    triangular shape, resulting in the fuselage's distinctive appearance, and bullet resistant window
    panels of nearly three inch thickness.
    Driven by two 485 horsepower Argus As410A air cooled engines, the prototype first flew in
    April of 1939. In spite of displaying lackluster handling qualities, it was approved for
    production later that year as the Hs-129A.
    Hs 129 B
    In an attempt to improve flight performance, the original Argus engines were replaced by more
    powerful French-built Gnome-Rhone 14M radials that were secured after the fall of France in
    1940. The redesigned Hs 129 B first took to the air in the summer of 1941 and became
    operational later that year.
    Hs 129 B-1
    The need for an effective airborne tank destroyer became painfully evident following the Red
    Army's overwhelming winter counteroffensive of 1941-42. With massed formations of Soviet
    armor penetrating deep behind German lines, urgent priority was given to the Hs 129's
    production.
    In addition to the standard fixed armament of paired 20 mm cannon and 7.92 mm machine
    guns, the B1/R2 variant featured a MK 101 30 mm automatic cannon housed in a ventrally
    mounted external weapons pod. Production of the B1/R2 version began in January of 1942,
    with the first units being delivered to the Eastern Front in April.
    Hs 129 B-2
    By May 1942 deliveries of the new Hs 129 B-2 model started side-by-side with the B-1. The
    only difference between the two were changes to the fuel system – a host of other minor
    changes could be found almost at random on either model. As time went on these changes
    accumulated in the B-2 production line until they could finally be told apart at a glance, the
    main differences being the removal of the mast for the radio antenna, the addition of a
    direction-finding radio antenna loop and engine intake filters.
    In the field, the differences seemed to be more pronounced. The R-kits were renumbered and
    some were dropped, and in general, the B-2 planes received the upgraded cannon pack using
    a 30 mm MK 103 cannon instead of the earlier MK 101. These guns both fired the same
    ammunition, but the 103 did so at almost twice the rate.
    Hs 129 B-3
    The final version was the most daunting, both to Soviet tank crew and Luftwaffe pilot. With a
    75 mm BK 7.5 cannon slung underneath its fuselage, the Hs 129 B-3/Wa became a true aerial
    tank. The aircraft's devastating firepower earned it the title of Buchsenoffner, or "tin opener".
    Such a weapon, however, made an already ponderous aircraft even more demanding of its
    pilots.
    10 / 35
    When construction of the Hs 129 was halted in September of 1944, a total of 868 (all versions)
    had been produced. Although proving to be a highly effective weapon against Soviet armored
    vehicles, Germany's overburdened war industry was simply incapable of manufacturing the Hs
    129 in enough numbers to have a significant strategic impact.

    Polikarpov I-15bis
    In 1933, Russian Nicolay Polikarpov developed one of the most outstanding biplanes ever used
    in combat. The Polikarpov I-15 had amazing combat performance due to its gull-shaped top
    wing that allowed the plane to do a complete turn in eight seconds. Although the first 59
    planes were built with an American 630hp Wright Cyclone engines, they were quickly replaced
    with Soviet made M-22 and M-25 radial engines that increased the horsepower.
    Pilots of the I-15 had two main complaints. The gull-shaped wing did not allow the pilots to
    view the horizon during flight and especially while landing. Also, at high speeds the plane was
    unstable during level flight, which would complicate the attack of an enemy airplane and make
    it difficult to aim the machine gun. In 1935 Nicolay Polikarpov was asked to design and perfect
    the I-16 monoplane by the Air Force Red Army in response to the negative feedback on the I-
    15 from pilots.
    The Polikarpov I-15 did not go away. In October of 1936 the Soviet Union sent a squadron of
    I-15's to the support of the Spanish Republic, where these manoeuvrable biplanes were
    unexpectedly popular in their combat role.
    Inexperienced pilots could learn to fly the Polikarpov I-15 very quickly and it was easy to take
    off and land. This new found excitement for the plane forced the Soviet Air Force to renew
    their manufacturing contract for more Polikarpov I-15's with a few modifications from Nicolay.
    The top wing was no longer gull-shaped, the M-25 750hp engine was installed, and a new
    exhaust system added, to make up this new I-15bis. The term "bis" meant second version or
    variant. In 1938, 1104 I-15bis airplanes were manufactured which made it the most mass
    produced Soviet fighter of that period. In 1939, an additional 1304 Polikarpov I-15bis aircraft's
    were produced, just before the contract was over and production of the I-153 began. The final
    27 Polikarpov I-15bis to roll off the assembly line were equipped with the M-62 900hp engine.
    Soviet Air Force pilots came to love the I-15bis because all of the flaws from the previous
    version were absent and the plane was very stable and performed excellently in combat. In
    1941 there were still several Polikarpov I-15bis aircraft patrolling the borders of the USSR.
    They began to be used for auxiliary tasks such as investigating artillery fire, destruction of
    nightlights, night attacks, and anti submarine defense along the coast. Slowly they were
    replaced by the MiG-3, LaGG-3 and the Yak-1.
    The I-15bis remained at several airfields and warehouses as their replacements were being
    delivered. During the many years of service the I-15bis was used in Spain, Mongolia, Finland,
    Russia, and even during the Japanese campaign in 1945.

    Curtiss-Wright CW-21B
    The Curtiss-Wright Model 21 (also known as the Curtiss-Wright Model 21 Demonstrator, the
    Curtiss-Wright CW-21 Interceptor, the Curtiss-Wright CW-21 Demon) was a United States-built
    interceptor fighter aircraft, developed by the St. Louis Airplane Division of Curtiss-Wright
    Corporation during the 1930s.
    The CW-21 was not commissioned by the U.S. military, though it was test flown at Wright Field
    in Dayton, Ohio. The Army Air Corps immediately rejected the aircraft, with one officer
    commenting that it took a genius to land it. Instead it was developed for export sales by the
    St. Louis Airplane Division of Curtiss-Wright. The aircraft was a single seat, all-metal cantilever
    low-wing monoplane with rearward retracting landing gear. The Model 21 was powered by a
    1000hp (746kW) Wright Cyclone nine cylinder air-cooled radial Wright R-1820-G5 engine. The
    Model 21 was designed by George A. Page, Jr. based on Carl W. Scott's design of the twoseater
    Model 19. The prototype first flew in January 1939 and bore the civil experimental
    registration NX19431. The prototype was designed to carry various combinations of two 7,62
    (0.303in) or 12,7mm (0.5in) machines guns, mounted in the nose and synchronized to fire
    through the propeller.
    The first sale of the CW-21 Demon in 1939, was to the Chinese Air Force, which received three
    completed examples and kits for 32 more. Assembly would be undertaken by the Central
    Aircraft Manufacturing Company (CAMCO) located in Loiwing on the China-Burma border.
    Three CW-21s were furnished to the Chinese as kits, assembled in Loiwing, and delivered to
    the 1st American Volunteer Group (Flying Tigers). These crashed in poor visibility on a flight
    from Rangoon to Kunming on 23 December 1941.
    In 1940, The Netherlands ordered 24 examples of a modified version designated the CW-21B
    (together with a number of two-seat CW-22), for the Royal Netherlands East Indies Army
    Military Aviation (Militaire Luchtvaart van het Koninklijk Nederlands-Indisch Leger; ML-KNIL).
    The modifications consisted of inward retracting landing gear, a semi-retractable tail wheel and
    a slightly larger fuel tank. These changes gained an 8mph (13km/h) speed increase at sea
    level.
    Deliveries started in June 1940, but only 17 had been received by Vliegtuigroep IV, Afdeling 2
    (No. 2 Squadron, Air Group IV; 2-VLG IV), when war with Japan began on December 8, 1941.
    With its rudimentary pilot protection, lack of self-sealing fuel tanks and light construction, the
    CW-21B was not unlike the opposing Japanese planes. It had similar firepower to the Nakajima
    Ki-43 "Oscar", but worse than the cannon-armed A6M Zero. Its climb rate wasn’t
    much better than either. Squadron VLG IV claimed four aerial victories during the Netherlands
    East Indies campaign but the ML-KNIL was overwhelmed by the sheer number of Japanese
    adversaries, and soon lost most of its aircraft in air combat or on the ground. Japan has
    captured at least one CW-21.

    Reggiane Re.2000 "Falco" - Heja I
    The Re.2000 was designed by Ing. Longhi of Caproni Reggiane, who has worked in the USA
    previously, and the plane had a strong exterior resemblance with Severski P-35 (though being
    more aerodynamically refined and with much better performance). The prototype flew in May,
    1939. The design included a "wet wing" to store fuel (in the center section of the wing). This
    was judged unfit for war use by Regia Aeronautica and the aircraft was discarded.
    On the other hand, Sweden, Hungary and Great Britain were interested in the plane and all of
    them placed orders (the British order for 300 planes was canceled after the declaration of
    war).
    Due the shortage of fighters even Regia Aeronautica employed small numbers of Re.2000s,
    mainly for action over Malta, for which a field modification for carrying two 100kg bombs was
    adopted. Also a version was produced for catapult launch from Italian warships, but they saw
    no operational use.
    Hungary employed about 70 Re.2000s that saw an intense use as fighters on the Eastern
    front, and later developed a license built version (Heja II.) with different engine (Gnome Rhone
    K-14) and machine guns (Gebauer 12,7mm).
    Sweden employed 60 Re.2000s for air space patrol. The Re.2000 was reported by all pilots for
    having good power and good handling features. However, maintenance and reliability of the
    Piaggio engine was troublesome.

    Ju 88 A-4/Torp
    The Ju 88 A-4 / Torp was a modification of the Ju 88 A-4 introduced in the Summer of 1942 on
    which the bomb racks were replaced by two PVC1000 racks for carrying torpedoes. Other
    modifications were the deletion of the dive breaks and the addition of a fairing on the fuselage,
    which contained the device to adjust the steering angle of the torpedo. The main weapons
    carried were a pair of LT F5b or LT F5W torpedos. Also, many examples were fitted with a field
    mounted MG FF cannon for suppression of ship’s AA.
    Implementation in IL2: in this patch the Ju 88 A-4 / Torp can carry both the LT F5b and LT
    F5W. Also, provision for practice torpedoes is given.
    Note: For all 2x torpedo loadouts there is a "salvo" option available that mission builders can
    use for AI planes. When a "salvo" loadout is selected both torpedoes are released
    simultaneously.
    Ju 88 A-17
    The Ju 88 A-17 was a further modification of the Ju 88 A-4/Torp, on which the gondola under
    the fuselage was removed to improve performance. Crew was reduced to three. This version
    was introduced in late 1943 and had the same armament options of the Ju-88 A-4/Torp.
    Implementation in IL2: in this patch the Ju 88 A-17 can carry both the LT F5b and LT F5W.
    Also, provision for practice torpedoes is given.
    Note: For all 2x torpedo loadouts there is a "salvo" option available that mission builders can
    use for AI planes. When a "salvo" loadout is selected both torpedoes are released
    simultaneously.
    He 111 H-12
    He 111 H-12 was an evolution of He 111 H-6 designed to be equipped with the Henschel Hs
    293 guided rocket. It had a new general-purpose ventral bomb rack and had the ventral
    gondola and waist guns removed. Some examples had an enclosed dorsal turret. The dorsal
    weapon was a MG 131.
    Implementation in IL-2
    This aircraft can also be equipped of The Fritz-X guided bomb, Fritz-X was historically used by
    He-111 H-12 for tests.
    Spitfire variants
    Several new Spitfires haven been added and others have been modified. The IL-2 simulation
    now contains the following models:
    • Seafire F III, 1943: A Seafire model with a Merlin 55 engine at 16lbs boost with good
    performance at medium altitude.
    • Seafire L III, 1943: A Seafire model with a Merlin 55M engine at 18lbs boost with
    good performance at low altitude.
    • Spitfire F Vb early, 1941: The first Spitfires Mk.Vb with a Merlin 45 engine at 12lbs
    boost. The Merlin 45 gave better high altitude performance than the early Merlins in the
    Spitfire Mk.I and II. Early models had some shortcomings when compared to later
    versions, for example they would cut out under negative G.
    • Spitfire F Vb, 1941: A typical Spitfire Mk.Vb for 1941 with a Merlin 45 engine at 12lbs
    boost. It is equipped with the "Shilling Orifice", a device that prevented the engine
    cutting out under negative G.
    19 / 35
    • Spitfire F Vb, 1942: A typical Spitfire Mk.Vb from the summer of 1942 on with a
    Merlin 45 engine at 16lbs boost. It has even better performance than the 1941 model
    at medium and low altitudes. It is also equipped with the "Shilling Orifice".
    • Spitfire F Vb CW, 1943: The same plane as the Spitfire F Vb, 1942, but with clipped
    wingtips. This gives a slightly higher speed at low altitude and a somewhat better roll
    rate, at the expense of high altitude speed, climb and turn performance.
    • Spitfire LF Vb, 1942: A Spitfire Mk.Vb with a Merlin 45M engine at 18lbs. It improves
    low level performance at the expense of medium and high altitude performance. It is
    equipped with the "Shilling Orifice".
    • Spitfire LF Vb CW, 1943: The same plane as the Spitfire LF Vb, 1942, but with clipped
    wingtips.
    • Spitfire F Vb Merlin46, 1942: A typical Spitfire Mk.Vb with a Merlin 46 engine at
    16lbs boost. This engine had a supercharger tuned for higher altitudes than that of the
    Merlin 45. This gave the plane a better performance at high altitudes. The drawback
    was worse performance at medium and low altitude. For this reason, many pilots
    preferred the Spitfires with Merlin 45 engines.
    • Spitfire F Vc(2)tr, early 1942: A tropicalized Spitfire Mk.Vc with a Merlin 45 engine
    at 12lbs boost. The Vc was build in parallel with the Vb. It was different by using the
    universal C wing, which could use several different armament configuration. This model
    uses a layout with two Hispano 20mm cannons and four 0.303 machine guns. It is a
    tropicalized model, equipped with the bulky Vokes airfilter which caused a lot of drag
    and reduced the altitude performance of the plane. Tropicalized Spitfires also carried
    extra equipment, such as a water ration for the pilot in case of an emergency landing in
    the desert, which overall made these models heavier than the standard versions.
    Tropicalized Spitfires were mainly used in North Africa and Asia.
    • Spitfire F Vc(2)tr, 1942: A tropicalized Spitfire Mk.Vc with a Merlin 45 engine at 16lbs
    boost. It has better performance than the early 1942 version at medium and low
    altitude.
    • Spitfire F Vc(4)tr, early 1942: The same plane as the Vc(2)tr, 1942, but with four
    20mm cannons in the C wing. The extra firepower of this configuration came with a
    considerable weight penalty and cost a lot of performance, so it was discontinued in
    favour of the standard dual cannon configuration.
    • Spitfire LF VIII, 1943: The Mk.VIII was intended to replace the Mk.V, but, due to the
    success of the Mk.IX, never did. It features a reworked, slightly stronger and less
    draggy fuselage, a higher fuel capacity and a Merlin 66 engine at 18lb boost. With the
    exception of a higher range, the performance is very comparable to the Mk.IX with the
    same engine. The Mk.VIII was used side by side with the Mk.IX.
    • Spitfire LF VIII CW, 1943: The same plane as the Spitfire VIII, 1943, but with
    clipped wingtips.
    • Spitfire F IX, 1942: The first Spitfires with a two stage supercharger. It was powered
    by a Merlin 61 engine at 15lb boost. It started to come off the assembly lines in the
    summer of 1942. The two stage supercharger gave it a clearly better high altitude
    performance than that of the contemporary Mk.V. The high altitudes this plane could
    reach necessitated a fuel cooler, so that the fuel in the tanks would not evaporate in the
    low pressure environment up high. The plane was used until the wars end.
    • Spitfire F IX, 1943: The second major model of the Mk.IX with a Merlin 63 engine at
    18lb boost. It was the major model of the Mk.IX in the first half of 1943. It outperforms
    the 1942 model at medium and low altitudes. It was used until the wars end.
    • Spitfire LF IX, 1943: In the second half of 1943, the Spitfire Mk.IX started to be
    equipped with the Merlin 66 engine at 18lb boost. This engine was optimized for lower
    altitudes than the Merlin 63. The need for a fuel cooler was eliminated by using
    pressurized tanks and a universal air intake became standard at that time. The Merlin
    66 models became the by far most common subversions of the Mk.IX.
    20 / 35
    • Spitfire LF IX CW, 1943: The same plane as the Spitfire LF IX, 1943, but with clipped
    wingtips. The removal of the wingtips became a more and more popular modification
    and by the wars end, the majority of the Spitfires LF IX had them removed.
    • Spitfire LF IX 25lbs: In a late war modification, the Merlin 66 was cleared for 25lb
    boost. This required the use of 150 octane fuel and not all Spitfires were converted. The
    extra boost gave the plane a considerable increase in performance at medium and low
    altitude.
    • Spitfire LF IX(e), 1944: The same plane as the Spitfire LF IX, 1943, but with a
    modified wing. This modification eliminated the four 0.303 guns in favor of two 0.50
    guns and allowed for more ammunition for the 20mm cannons. This modification
    resulted in a slight weight penalty.
    • Spitfire LF IX(e) CW, 1944: The same plane as the Spitfire LF IX(e), 1944, but with
    clipped wingtips.
    • Spitfire LF IX(e) CW 25lbs: The same plane as the Spitfire LF IX(e) CW, 1944, but
    with the modification that allowed the Merlin 66 to run at 25lb boost.
    • Spitfire HF IX,1944: A high altitude Spitfire Mk.IX subversion, powered by a Merlin 70
    at 18lb of boost. Its performance was worse than the more popular model with the
    Merlin 66 engine at all but the highest altitudes.
    • Spitfire HF IX(e),1944: The same plane as the Spitfire HF IX,1944, but with the (e)
    wing modification.
    New AI Planes
    Dornier Do 217 K
    The Dornier Do 217 was a bigger and more powerful development of the Do 17 (the famous
    "flying pencil"). The Do 217 entered service in 1942, and was used for strategic bombing
    (mainly at night), tactical bombing, reconnaissance and anti-shipping attack. Two versions
    (versions J and N) were developed as a night fighter. The K version has a distinctive stepless,
    more streamlined cockpit, giving less drag than previous versions. Engines were the BMW801
    radials. </div></BLOCKQUOTE>

    Structural G Limits
    Before 4.10 patch all aircraft in IL2 have a single fixed Structural G limit of +13.5G. It only
    really becomes an issue with aircraft with exceptionally light elevators such as the P-51. Pull
    more than +13.5G and you loose your wings. The real life situation is a little more
    complicated. Real aircraft are designed with an Ultimate load and In Service design load. Both
    are for a defined configuration and weight.
    In Service load is the typical G available to the pilot. As long as this the G is not exceeded then
    no aircraft damage will occur. Exceed the In service G limit then damage of varying degrees
    may occur like bent airframes etc. Exceed the Ultimate load then severe damage will occur
    typically resulting in structural failure like wings coming off etc. Typically a safety factor of 1.5
    is used. So fighter plane with a design In service G limit of say +8G will have an Ultimate load
    of +12G. As external stores and or weight is increased above the design weight, both G limits
    reduce accordingly. Reduce weight (by dropping bombs or burning fuel etc.) and your G limits
    increase. Bomber and Transport aircraft have G limits much lower than fighters.
    So if you abuse the limits you damage the aircraft. Once damaged then its structural integrity
    is reduced so the ultimate load reduces as well. In other words keep bending the airframe and
    you will eventually weaken it to the point that very little extra G is required to induce
    structural failure. A bent airframe won’t perform as well either.
    How does this work in game? You take your stock standard Fighter Mk 1 with default
    armament +100% Fuel your limits are +8G/+12G. You add 2 x 500lbs bombs. Your limits now
    reduce to 5G/8G. So prior to the target you need to be a little more careful with your plane.
    Lets say pre target you pull + 6G, you have exceeded the “in service” limit, you will hear a
    damage sound cue and suffer a slight aerodynamic penalty. In addition your G limits have now
    reduced to say 5G/6G. Bust these again and further aerodynamic penalties and further
    reductions will apply. You progress to the target and release your bombs. Since the weight is
    reduced your limits will increase but since you already bent the airframe you won’t get back
    your original limits. You might then get say +8G/+10G. As you can see if you keep abusing the
    limits you will end with a very weakened airframe.
    In the case of heavy bombers, G limits will prevent any real aerobatic maneuvers. You will still
    be able to evade quite well but you wont be able to BFM with plane like the A-20 anymore.
    Bombers will be just that: Bombers.
    G Indications
    When the speedbar is enabled an indication of proximity to the Service limit is provided. When
    you get within 25% of the current Service limit a "G" will be displayed on the top of the
    speedbar. As you get to within 10% of the current Service limit the "G" will begin to flash. The
    process being reversed as you reduce the G. No G cueing is provided if Speed bar is
    deselected.
    If players use No Cockpit View than direct readout of G is provided. Number is white while G's
    are above 0, when you get within 25% of the current Service limit number turns to red. Below
    0G,number is black.
    Quick Mission Builder (QMB)
    Additional Flights
    It is now possible to have 16 flights in QMB (8 vs. 8). On the first page of QMB are first 4
    friendly and 4 enemy flights. The player's flight is the first friendly flight on the first page.
    Additional flights can be reached by clicking on the "Next" button at the bottom.
    5 / 35
    Statistics Page
    On the second QMB page you will notice a new button called "Stats". It leads to the QMB
    statistics page. There are all sorts of statistical categories for you to enjoy. Statistics are now
    kept for your last flown QMB mission, last played session (series of missions you play before
    you exit the game) and, of course, statistics of your whole career. There is also a "Reset Stats"
    button at the bottom.
    Plane Lists
    At the bottom right part of the first QMB page there is a Plane List drop down list. There are
    two planes lists immediately available: Standard and Alphabetical. When the first one is
    selected all planes are ordered as usual. When you select Alphabetical list planes are sorted
    alphabetically. You can also create two additional plane lists on your own: QMBair_2.ini and
    QMBair_3.ini. Place them in the Missions/Quick/ folder. The structure of the files must look
    something like this:
    [AIR]
    BeaufighterMk21
    BlenheimMkIV
    BI-1
    BI-6
    BuffaloMkI
    You can have planes you like in those lists and only those will appear in the plane drop down
    menus. Also you can add the line DumpPlaneList=1 to [QMB] section and the game will dump
    the list of all planes in correct format to Missions/Quick/FullPlaneList.dump file.
    Adding more Missions
    You can also create new missions for QMB. Your favorite map is not in? No problem, add it
    yourself. First you need to create the mission in FMB and make 8 flights for each side. Use
    default squadrons only. Then you have to name them properly according to certain rules. First
    make a new folder in Missions/Quick/ folder. Place the mission there and make sure that the
    first part of the mission name is exactly the same as the name of the folder you created. The
    second part of the mission filename determines the army of the player (Red or Blue). The next
    part determines the mission type (Airbase, Armor, Bridge, NoneN, NoneA, NoneD or
    Scramble). The last part are two numbers for stock missions, but can be practically anything
    (like DaidalosCoolestMissionsEver00001). If you have several missions which only differ in the
    last part of the filename (meaning that map, army and mission type are the same), QMB will
    pick one randomly when the mission is started by the player.
    If you plan to share your missions with others, it's best to use internal map name which is
    automatically translated to other localizations. Also it would be nice to use distinctive last part
    of the filename (like Daidalos... example above), so users can combine your missions with
    other authors for some variety.
    There is nothing stopping you from making fake missions, for example mission named:
    KievBlueArmorCoolAppendix99.mis which actually loads Norway map with None target and
    player at disadvantage. The GUI elements in QMB are filled according to mission filename, not
    according to what is actually written in the mission file.
    Reset
    There is a Reset button on the first QMB page which resets all flights to default values (number
    of planes, selected planes and loadouts). Also, each time you exit the game, mission settings
    are stored and loaded automatically when you start Il-2 another time.
    6 / 35
    Full Mission Builder (FMB)
    Selecting Multiple Objects
    To select/deselect multiple objects in FMB you need to have these commands enabled in your
    conf.ini. Check the [HotKey builder] section for these two commands:
    Alt MouseLeft=select+
    Alt MouseRight=select-
    Hold down the [ALT] key and left mouse button press and 'draw' a rectangle around some
    ground objects. All appropriate objects are grouped into a single selection (multiselection). Do
    this again on another group of objects and they are added to the multiselection. Naturally, by
    holding down the [ALT] key and right mouse button you can remove objects from the selection
    by 'drawing' a rectangle around them. Not all objects can be added to the multiselection. Here
    is a list of those than can:
    • Artillery
    • Stationary Armor
    • Stationary Objects
    • Stationary Aircraft
    • Stationary Ships
    • Rocket
    • Objects
    • Static Camera
    If you want to unselect all objects you can do that through Edit -> Unselect All option in the
    menu.
    Cut / Copy / Paste / Delete / Move
    Add these commands to your conf.ini
    Ctrl C=mis_copy
    Ctrl X=mis_cut
    Ctrl V=mis_paste
    to be able to perform these commands. When you have some objects in multiselection execute
    the copy or cut command. Click somewhere on the map and then paste them. You can paste
    them multiple times. You can also delete the entire multiselection by pressing the [DELETE]
    button on your keyboard. You can also move your multiselection. First add some objects to
    multiselection. Then press and hold left mouse button above one of the objects in
    multiselection. Still holding the left mouse button move your mouse cursor to the desired
    location on the map.
    Rotation
    When you have created a multiselection, you can rotate the whole group of objects. Left click
    somewhere on the map and use your numpad keys to rotate the group of objects around the
    mouse position. There are two types of rotation: when individual objects change their
    orientation with respect to the world coordinates (when the option Edit -> Rotate Object is
    checked) and when individual objects maintain their original orientation.
    Snap
    Snap allows you to move objects along a grid. This helps placing objects with equal distance to
    each other. This option can be reached through View -> Snap. Make sure that the option is
    checked. You can also set the 'snap step'. Smaller step makes the grid where objects can be
    placed denser.
    7 / 35
    Load / Save dialog box
    You can change the default size of the Load/Save dialog box which is useful if you have many
    missions saved. Open the bldconf.ini file and set the values of defFullDX and defFullDY
    variables to suit your needs.
    Mission Date
    Clicking on the Configure -> Conditions you will notice that the dialog box has new tab "Date".
    You can set the precise day, month and year of your mission there.
    Wind
    “Weather” tab in the Configure -> Conditions dialog box now has new set of parameters that
    adjust the wind in the mission. It's possible to set Wind direction, Wind velocity, Gust and
    Turbulence. Wind direction is as per aviation standards and is entered as where the wind is
    blowing from. A westerly wind is entered as 270.
    Multi-throttle/prop support and radiator axis
    4.10 patch introduces following new axis for HOTAS controls:
    • Engine 1 Power
    • Engine 2 Power
    • Engine 3 Power
    • Engine 4 Power
    • Engine 1 Prop Pitch
    • Engine 2 Prop Pitch
    • Engine 3 Prop Pitch
    • Engine 4 Prop Pitch
    These directly control their assigned engines.
    • Radiator
    Axis controlling radiator opening.
    • Zoom
    changes field of view
    The player needs to map these axis before multi-throttle/prop for separate engines work. For
    compatibility reasons Team Daidalos decided that all existing controls should stay in place and
    work in parallel to new ones. If you have for example both Power and Engine 1 Power mapped
    and engine 1 selected, both axes will fight together and last input will be used every time.
    Radiator is same except there are axis and key interacting in this fashion.
    Automatic radiators: you still have to use the radiator key to activate auto mode. There is
    special part of Radiator axis travel (approx. above 80%), any movement in this range will not
    switch radiator out of automatic mode.
    Advanced joystick profiles
    General Concept
    Previously you were adjusting sensitivity of your Joystick primary axes. Team Daidalos
    changed this so that you actually adjust response of your controls. This means that any control
    listed in HOTAS section of Controls menu can be adjusted. All you have to do is assign
    something to the desired control and it will appear in the Joystick menu top left drop down list.
    8 / 35
    Controls Response
    Choosing one of the primary controls (ailerons, elevator and rudder) you won't see much
    difference from the previous method. Ailerons and elevator responses are shown in the big
    square box, while the rudder response is shown in the bottom horizontal rectangle. As usual
    you can adjust sensitivity, dead band and filtering. If you choose any other control (like Power
    or Prop Pitch) additional vertical response rectangle will be shown on the right. You can adjust
    sensitivity, dead band and filtering for that control also.
    Symmetrical Switch
    Some of the control axes behave symmetrically (or mirrored). For example you probably want
    your ailerons sensitivity curve to be the same if you push your joystick to the left and right.
    But it doesn't make much sense to do that for Power control, for example. That's where the
    Symmetrical switch comes into play. Turn it off and the sensitivity will be applied over the
    whole range of values without trying to make them symmetrical. In other words, ailerons and
    similar controls have values from -100% to 100% and you want the sensitivity to be mirrored
    around zero value. Power, on the other hand, is more logically described as a control with
    values ranging from 0% to 100%. You probably want this control to have different sensitivity
    response over the whole range.
    Joystick Profile
    As before you can use 4 different Joysticks (or similar devices) to control your plane in IL-2.
    But in addition to that, now you can have 4 different Joystick profiles stored in IL-2. Please
    don't confuse 4 different physical Joysticks with 4 different Joystick profiles. What's this all
    about? Well you can adjust your sensitivity curves to suit TnB fighter and save it as your first
    profile (click Save button).
    If you find yourself flying a BnZ fighter, those settings might not suit you. No problem, switch
    to a different profile (top drop down menu and click Load) and use you BnZ fighter settings. As
    there are 4 profiles available, you can use one for bombers or ground-attack planes. It's all up
    to you to make sensitivity profiles for your specific needs. You might find this feature rather
    useful considering the new G-limits in 4.10 patch.
    Changing Joystick Profile
    Joystick setup menu can now also be reached with a button from Air Arming screen. Why from
    there? Well, this menu appears in every gameplay type: single, dogfight, coop. That means
    that you can switch to a different Joystick profile (or even adjust it) without disconnecting from
    the server. Switching from Red to Blue or from Fighter to Bomber has never been easier.
    Engine Reliability Difficulty Option
    All engines have now small chance of failure at every moment of flight. Probability depends on
    power generated by engine and its RPM (more power, bigger chance for an engine to fail). Not
    every failure is catastrophic, some of them just reduce power, but if its not your lucky day
    then you might end up with a problem. Purpose of this feature is to give a reason to be easy
    on engine, not to follow historical failure rates of specific engines. This can be turned off in
    difficulty settings.
    Improved Pilot Damage Difficulty Option
    With this difficulty option turned on, damage to the pilot is more severe. Being hit is something
    that has very serious consequences now. That apply to AI pilots and gunners too, it is much
    easier to kill them. You will have to adjust your tactics to accommodate this change, avoid
    being hit at all costs and when on attack, aim at the cockpit, especially if you are in plane
    armed with light machine guns only. Against bombers, aim at gunners first to disable them,
    you are better protected and you have more guns than them.
    As you can imagine, if you can get killed easier, than you can get wounded easier too. In
    9 / 35
    addition, there are more variations in wounds, you can get hit in the arm or leg with a
    corresponding loss of control over the plane. To make things even more complicated, some
    wounds will cause bleeding and you can bleed to death unless you reach home in time.
    Gunners ability to shoot is also reduced when they get wounded.
    New Flyable Planes
    Henschel Hs 129
    The Henschel Hs 129 was developed by engineer Friedrich Nicholaus in response to a 1937
    request by the German Air Ministry for a small, heavily armored ground attack/support aircraft
    equipped with a minimum of two 20 mm cannon and two rifle caliber machine guns. Nicholaus'
    design stressed pilot survivability. The cockpit was surrounded by an armor plated "bathtub" of
    triangular shape, resulting in the fuselage's distinctive appearance, and bullet resistant window
    panels of nearly three inch thickness.
    Driven by two 485 horsepower Argus As410A air cooled engines, the prototype first flew in
    April of 1939. In spite of displaying lackluster handling qualities, it was approved for
    production later that year as the Hs-129A.
    Hs 129 B
    In an attempt to improve flight performance, the original Argus engines were replaced by more
    powerful French-built Gnome-Rhone 14M radials that were secured after the fall of France in
    1940. The redesigned Hs 129 B first took to the air in the summer of 1941 and became
    operational later that year.
    Hs 129 B-1
    The need for an effective airborne tank destroyer became painfully evident following the Red
    Army's overwhelming winter counteroffensive of 1941-42. With massed formations of Soviet
    armor penetrating deep behind German lines, urgent priority was given to the Hs 129's
    production.
    In addition to the standard fixed armament of paired 20 mm cannon and 7.92 mm machine
    guns, the B1/R2 variant featured a MK 101 30 mm automatic cannon housed in a ventrally
    mounted external weapons pod. Production of the B1/R2 version began in January of 1942,
    with the first units being delivered to the Eastern Front in April.
    Hs 129 B-2
    By May 1942 deliveries of the new Hs 129 B-2 model started side-by-side with the B-1. The
    only difference between the two were changes to the fuel system – a host of other minor
    changes could be found almost at random on either model. As time went on these changes
    accumulated in the B-2 production line until they could finally be told apart at a glance, the
    main differences being the removal of the mast for the radio antenna, the addition of a
    direction-finding radio antenna loop and engine intake filters.
    In the field, the differences seemed to be more pronounced. The R-kits were renumbered and
    some were dropped, and in general, the B-2 planes received the upgraded cannon pack using
    a 30 mm MK 103 cannon instead of the earlier MK 101. These guns both fired the same
    ammunition, but the 103 did so at almost twice the rate.
    Hs 129 B-3
    The final version was the most daunting, both to Soviet tank crew and Luftwaffe pilot. With a
    75 mm BK 7.5 cannon slung underneath its fuselage, the Hs 129 B-3/Wa became a true aerial
    tank. The aircraft's devastating firepower earned it the title of Buchsenoffner, or "tin opener".
    Such a weapon, however, made an already ponderous aircraft even more demanding of its
    pilots.
    10 / 35
    When construction of the Hs 129 was halted in September of 1944, a total of 868 (all versions)
    had been produced. Although proving to be a highly effective weapon against Soviet armored
    vehicles, Germany's overburdened war industry was simply incapable of manufacturing the Hs
    129 in enough numbers to have a significant strategic impact.

    Polikarpov I-15bis
    In 1933, Russian Nicolay Polikarpov developed one of the most outstanding biplanes ever used
    in combat. The Polikarpov I-15 had amazing combat performance due to its gull-shaped top
    wing that allowed the plane to do a complete turn in eight seconds. Although the first 59
    planes were built with an American 630hp Wright Cyclone engines, they were quickly replaced
    with Soviet made M-22 and M-25 radial engines that increased the horsepower.
    Pilots of the I-15 had two main complaints. The gull-shaped wing did not allow the pilots to
    view the horizon during flight and especially while landing. Also, at high speeds the plane was
    unstable during level flight, which would complicate the attack of an enemy airplane and make
    it difficult to aim the machine gun. In 1935 Nicolay Polikarpov was asked to design and perfect
    the I-16 monoplane by the Air Force Red Army in response to the negative feedback on the I-
    15 from pilots.
    The Polikarpov I-15 did not go away. In October of 1936 the Soviet Union sent a squadron of
    I-15's to the support of the Spanish Republic, where these manoeuvrable biplanes were
    unexpectedly popular in their combat role.
    Inexperienced pilots could learn to fly the Polikarpov I-15 very quickly and it was easy to take
    off and land. This new found excitement for the plane forced the Soviet Air Force to renew
    their manufacturing contract for more Polikarpov I-15's with a few modifications from Nicolay.
    The top wing was no longer gull-shaped, the M-25 750hp engine was installed, and a new
    exhaust system added, to make up this new I-15bis. The term "bis" meant second version or
    variant. In 1938, 1104 I-15bis airplanes were manufactured which made it the most mass
    produced Soviet fighter of that period. In 1939, an additional 1304 Polikarpov I-15bis aircraft's
    were produced, just before the contract was over and production of the I-153 began. The final
    27 Polikarpov I-15bis to roll off the assembly line were equipped with the M-62 900hp engine.
    Soviet Air Force pilots came to love the I-15bis because all of the flaws from the previous
    version were absent and the plane was very stable and performed excellently in combat. In
    1941 there were still several Polikarpov I-15bis aircraft patrolling the borders of the USSR.
    They began to be used for auxiliary tasks such as investigating artillery fire, destruction of
    nightlights, night attacks, and anti submarine defense along the coast. Slowly they were
    replaced by the MiG-3, LaGG-3 and the Yak-1.
    The I-15bis remained at several airfields and warehouses as their replacements were being
    delivered. During the many years of service the I-15bis was used in Spain, Mongolia, Finland,
    Russia, and even during the Japanese campaign in 1945.

    Curtiss-Wright CW-21B
    The Curtiss-Wright Model 21 (also known as the Curtiss-Wright Model 21 Demonstrator, the
    Curtiss-Wright CW-21 Interceptor, the Curtiss-Wright CW-21 Demon) was a United States-built
    interceptor fighter aircraft, developed by the St. Louis Airplane Division of Curtiss-Wright
    Corporation during the 1930s.
    The CW-21 was not commissioned by the U.S. military, though it was test flown at Wright Field
    in Dayton, Ohio. The Army Air Corps immediately rejected the aircraft, with one officer
    commenting that it took a genius to land it. Instead it was developed for export sales by the
    St. Louis Airplane Division of Curtiss-Wright. The aircraft was a single seat, all-metal cantilever
    low-wing monoplane with rearward retracting landing gear. The Model 21 was powered by a
    1000hp (746kW) Wright Cyclone nine cylinder air-cooled radial Wright R-1820-G5 engine. The
    Model 21 was designed by George A. Page, Jr. based on Carl W. Scott's design of the twoseater
    Model 19. The prototype first flew in January 1939 and bore the civil experimental
    registration NX19431. The prototype was designed to carry various combinations of two 7,62
    (0.303in) or 12,7mm (0.5in) machines guns, mounted in the nose and synchronized to fire
    through the propeller.
    The first sale of the CW-21 Demon in 1939, was to the Chinese Air Force, which received three
    completed examples and kits for 32 more. Assembly would be undertaken by the Central
    Aircraft Manufacturing Company (CAMCO) located in Loiwing on the China-Burma border.
    Three CW-21s were furnished to the Chinese as kits, assembled in Loiwing, and delivered to
    the 1st American Volunteer Group (Flying Tigers). These crashed in poor visibility on a flight
    from Rangoon to Kunming on 23 December 1941.
    In 1940, The Netherlands ordered 24 examples of a modified version designated the CW-21B
    (together with a number of two-seat CW-22), for the Royal Netherlands East Indies Army
    Military Aviation (Militaire Luchtvaart van het Koninklijk Nederlands-Indisch Leger; ML-KNIL).
    The modifications consisted of inward retracting landing gear, a semi-retractable tail wheel and
    a slightly larger fuel tank. These changes gained an 8mph (13km/h) speed increase at sea
    level.
    Deliveries started in June 1940, but only 17 had been received by Vliegtuigroep IV, Afdeling 2
    (No. 2 Squadron, Air Group IV; 2-VLG IV), when war with Japan began on December 8, 1941.
    With its rudimentary pilot protection, lack of self-sealing fuel tanks and light construction, the
    CW-21B was not unlike the opposing Japanese planes. It had similar firepower to the Nakajima
    Ki-43 "Oscar", but worse than the cannon-armed A6M Zero. Its climb rate wasn’t
    much better than either. Squadron VLG IV claimed four aerial victories during the Netherlands
    East Indies campaign but the ML-KNIL was overwhelmed by the sheer number of Japanese
    adversaries, and soon lost most of its aircraft in air combat or on the ground. Japan has
    captured at least one CW-21.

    Reggiane Re.2000 "Falco" - Heja I
    The Re.2000 was designed by Ing. Longhi of Caproni Reggiane, who has worked in the USA
    previously, and the plane had a strong exterior resemblance with Severski P-35 (though being
    more aerodynamically refined and with much better performance). The prototype flew in May,
    1939. The design included a "wet wing" to store fuel (in the center section of the wing). This
    was judged unfit for war use by Regia Aeronautica and the aircraft was discarded.
    On the other hand, Sweden, Hungary and Great Britain were interested in the plane and all of
    them placed orders (the British order for 300 planes was canceled after the declaration of
    war).
    Due the shortage of fighters even Regia Aeronautica employed small numbers of Re.2000s,
    mainly for action over Malta, for which a field modification for carrying two 100kg bombs was
    adopted. Also a version was produced for catapult launch from Italian warships, but they saw
    no operational use.
    Hungary employed about 70 Re.2000s that saw an intense use as fighters on the Eastern
    front, and later developed a license built version (Heja II.) with different engine (Gnome Rhone
    K-14) and machine guns (Gebauer 12,7mm).
    Sweden employed 60 Re.2000s for air space patrol. The Re.2000 was reported by all pilots for
    having good power and good handling features. However, maintenance and reliability of the
    Piaggio engine was troublesome.

    Ju 88 A-4/Torp
    The Ju 88 A-4 / Torp was a modification of the Ju 88 A-4 introduced in the Summer of 1942 on
    which the bomb racks were replaced by two PVC1000 racks for carrying torpedoes. Other
    modifications were the deletion of the dive breaks and the addition of a fairing on the fuselage,
    which contained the device to adjust the steering angle of the torpedo. The main weapons
    carried were a pair of LT F5b or LT F5W torpedos. Also, many examples were fitted with a field
    mounted MG FF cannon for suppression of ship’s AA.
    Implementation in IL2: in this patch the Ju 88 A-4 / Torp can carry both the LT F5b and LT
    F5W. Also, provision for practice torpedoes is given.
    Note: For all 2x torpedo loadouts there is a "salvo" option available that mission builders can
    use for AI planes. When a "salvo" loadout is selected both torpedoes are released
    simultaneously.
    Ju 88 A-17
    The Ju 88 A-17 was a further modification of the Ju 88 A-4/Torp, on which the gondola under
    the fuselage was removed to improve performance. Crew was reduced to three. This version
    was introduced in late 1943 and had the same armament options of the Ju-88 A-4/Torp.
    Implementation in IL2: in this patch the Ju 88 A-17 can carry both the LT F5b and LT F5W.
    Also, provision for practice torpedoes is given.
    Note: For all 2x torpedo loadouts there is a "salvo" option available that mission builders can

    He 111 H-12
    He 111 H-12 was an evolution of He 111 H-6 designed to be equipped with the Henschel Hs
    293 guided rocket. It had a new general-purpose ventral bomb rack and had the ventral
    gondola and waist guns removed. Some examples had an enclosed dorsal turret. The dorsal
    weapon was a MG 131.
    Implementation in IL-2
    This aircraft can also be equipped of The Fritz-X guided bomb, Fritz-X was historically used by
    He-111 H-12 for tests.
    Spitfire variants
    Several new Spitfires haven been added and others have been modified. The IL-2 simulation
    now contains the following models:
    • Seafire F III, 1943: A Seafire model with a Merlin 55 engine at 16lbs boost with good
    performance at medium altitude.
    • Seafire L III, 1943: A Seafire model with a Merlin 55M engine at 18lbs boost with
    good performance at low altitude.
    • Spitfire F Vb early, 1941: The first Spitfires Mk.Vb with a Merlin 45 engine at 12lbs
    boost. The Merlin 45 gave better high altitude performance than the early Merlins in the
    Spitfire Mk.I and II. Early models had some shortcomings when compared to later
    versions, for example they would cut out under negative G.
    • Spitfire F Vb, 1941: A typical Spitfire Mk.Vb for 1941 with a Merlin 45 engine at 12lbs
    boost. It is equipped with the "Shilling Orifice", a device that prevented the engine
    cutting out under negative G.
    19 / 35
    • Spitfire F Vb, 1942: A typical Spitfire Mk.Vb from the summer of 1942 on with a
    Merlin 45 engine at 16lbs boost. It has even better performance than the 1941 model
    at medium and low altitudes. It is also equipped with the "Shilling Orifice".
    • Spitfire F Vb CW, 1943: The same plane as the Spitfire F Vb, 1942, but with clipped
    wingtips. This gives a slightly higher speed at low altitude and a somewhat better roll
    rate, at the expense of high altitude speed, climb and turn performance.
    • Spitfire LF Vb, 1942: A Spitfire Mk.Vb with a Merlin 45M engine at 18lbs. It improves
    low level performance at the expense of medium and high altitude performance. It is
    equipped with the "Shilling Orifice".
    • Spitfire LF Vb CW, 1943: The same plane as the Spitfire LF Vb, 1942, but with clipped
    wingtips.
    • Spitfire F Vb Merlin46, 1942: A typical Spitfire Mk.Vb with a Merlin 46 engine at
    16lbs boost. This engine had a supercharger tuned for higher altitudes than that of the
    Merlin 45. This gave the plane a better performance at high altitudes. The drawback
    was worse performance at medium and low altitude. For this reason, many pilots
    preferred the Spitfires with Merlin 45 engines.
    • Spitfire F Vc(2)tr, early 1942: A tropicalized Spitfire Mk.Vc with a Merlin 45 engine
    at 12lbs boost. The Vc was build in parallel with the Vb. It was different by using the
    universal C wing, which could use several different armament configuration. This model
    uses a layout with two Hispano 20mm cannons and four 0.303 machine guns. It is a
    tropicalized model, equipped with the bulky Vokes airfilter which caused a lot of drag
    and reduced the altitude performance of the plane. Tropicalized Spitfires also carried
    extra equipment, such as a water ration for the pilot in case of an emergency landing in
    the desert, which overall made these models heavier than the standard versions.
    Tropicalized Spitfires were mainly used in North Africa and Asia.
    • Spitfire F Vc(2)tr, 1942: A tropicalized Spitfire Mk.Vc with a Merlin 45 engine at 16lbs
    boost. It has better performance than the early 1942 version at medium and low
    altitude.
    • Spitfire F Vc(4)tr, early 1942: The same plane as the Vc(2)tr, 1942, but with four
    20mm cannons in the C wing. The extra firepower of this configuration came with a
    considerable weight penalty and cost a lot of performance, so it was discontinued in
    favour of the standard dual cannon configuration.
    • Spitfire LF VIII, 1943: The Mk.VIII was intended to replace the Mk.V, but, due to the
    success of the Mk.IX, never did. It features a reworked, slightly stronger and less
    draggy fuselage, a higher fuel capacity and a Merlin 66 engine at 18lb boost. With the
    exception of a higher range, the performance is very comparable to the Mk.IX with the
    same engine. The Mk.VIII was used side by side with the Mk.IX.
    • Spitfire LF VIII CW, 1943: The same plane as the Spitfire VIII, 1943, but with
    clipped wingtips.
    • Spitfire F IX, 1942: The first Spitfires with a two stage supercharger. It was powered
    by a Merlin 61 engine at 15lb boost. It started to come off the assembly lines in the
    summer of 1942. The two stage supercharger gave it a clearly better high altitude
    performance than that of the contemporary Mk.V. The high altitudes this plane could
    reach necessitated a fuel cooler, so that the fuel in the tanks would not evaporate in the
    low pressure environment up high. The plane was used until the wars end.
    • Spitfire F IX, 1943: The second major model of the Mk.IX with a Merlin 63 engine at
    18lb boost. It was the major model of the Mk.IX in the first half of 1943. It outperforms
    the 1942 model at medium and low altitudes. It was used until the wars end.
    • Spitfire LF IX, 1943: In the second half of 1943, the Spitfire Mk.IX started to be
    equipped with the Merlin 66 engine at 18lb boost. This engine was optimized for lower
    altitudes than the Merlin 63. The need for a fuel cooler was eliminated by using
    pressurized tanks and a universal air intake became standard at that time. The Merlin
    66 models became the by far most common subversions of the Mk.IX.
    20 / 35
    • Spitfire LF IX CW, 1943: The same plane as the Spitfire LF IX, 1943, but with clipped
    wingtips. The removal of the wingtips became a more and more popular modification
    and by the wars end, the majority of the Spitfires LF IX had them removed.
    • Spitfire LF IX 25lbs: In a late war modification, the Merlin 66 was cleared for 25lb
    boost. This required the use of 150 octane fuel and not all Spitfires were converted. The
    extra boost gave the plane a considerable increase in performance at medium and low
    altitude.
    • Spitfire LF IX(e), 1944: The same plane as the Spitfire LF IX, 1943, but with a
    modified wing. This modification eliminated the four 0.303 guns in favor of two 0.50
    guns and allowed for more ammunition for the 20mm cannons. This modification
    resulted in a slight weight penalty.
    • Spitfire LF IX(e) CW, 1944: The same plane as the Spitfire LF IX(e), 1944, but with
    clipped wingtips.
    • Spitfire LF IX(e) CW 25lbs: The same plane as the Spitfire LF IX(e) CW, 1944, but
    with the modification that allowed the Merlin 66 to run at 25lb boost.
    • Spitfire HF IX,1944: A high altitude Spitfire Mk.IX subversion, powered by a Merlin 70
    at 18lb of boost. Its performance was worse than the more popular model with the
    Merlin 66 engine at all but the highest altitudes.
    • Spitfire HF IX(e),1944: The same plane as the Spitfire HF IX,1944, but with the (e)
    wing modification.
    New AI Planes
    Dornier Do 217 K
    The Dornier Do 217 was a bigger and more powerful development of the Do 17 (the famous
    "flying pencil"). The Do 217 entered service in 1942, and was used for strategic bombing
    (mainly at night), tactical bombing, reconnaissance and anti-shipping attack. Two versions
    (versions J and N) were developed as a night fighter. The K version has a distinctive stepless,
    more streamlined cockpit, giving less drag than previous versions. Engines were the BMW801
    radials.

    The K-1 entered production in 1941, it had a crew of four, an armament of a twin
    MG81Z in the nose (replaced by a MG131 in some examples), two MG131s in a dorsal turret
    andventral gondola, and two MG81 in lateral positions. Bombload was up to 4000kg,
    maximum range was 2300Km, maximum speed was 515 Km/h at 5000m.
    Subsequently the K-2 version was produced with elongated wings (for better high altitude
    performance) and intended to carry the Fritz X guided gliding bomb. This version was used in
    the Mediterranean and Atlantic and was the first aircraft to score a hit with a guided weapon,
    sinking Italian battleship Roma in September 1943.
    Later the K-3 was developed which identical to K-2 but able to carry Hs 293 guided rocket.
    Implementation in Il-2
    In this patch of IL-2, K-1 and K-2 versions are implemented. For simplicity K-2 is also given
    the loadout option of K-3 (instead of defining a completely new plane model).
    AI planes are able to drop and guide both Hs 239 and Fritz X. Please see the respective guides
    for how to correctly program AI attacks with these weapons.
    Fairey Fulmar
    The Fairey Fulmar was a two-seat reconnaissance fighter adopted by the British Fleet Air Arm.
    It was designed to meet the Admiralty's urgent need for a modern shipboard fighter. The
    aircraft was delivered to the first operation unit, 806 in June 1940 stationed at Worthy Down
    and boarded HMS Illustrious in August 1940, where it was put into action against the Italian
    Air Force assisting Malta convoys.

    The Fulmar was also used over Crete and took part in shadowing the battleship Bismarck. With
    its lack of speed, and the Admiralty's need for a truly modern carrier-based fighter, the Fulmar
    began being replaced by the Supermarine Seafire by 1943.
    Top speed was 415 Km/h at 2750 m. Two underwing bomb (up to 250 lbs each) could be
    carried, also a detachable fuel tank was available as an external load.
    Cant Z.1007bis Alcione
    The Z.1007bis Alcione (Kingfisher) was Italy's finest three-engine medium bomber of the war.
    Its development started in 1935. By 1940 the aircraft went into production. The first version
    had 830 hp Isotta Fraschini Asso inline engines. Being underpowered, a second version (bis)
    was built, powered by three 1,000 hp Piaggio P.XI RC 40 radial air-cooled engines. This version
    was the one widely used operationally.
    A later variant had a twin rudder and fin for giving better field of fire to the dorsal gunner who
    operated a Caproni-Lanciani turret with a Scotti-Isotta Fraschini 12.7mm machine gun. Other
    guns were two 7,7mm Breda (lateral positions) and a 12.7mm Breda (ventral position). The
    Cant was used on all fronts and proved to be an effective and strong aircraft, despite structural
    problems in extreme climates due to its construction, made entirely of wood.
    Few examples were used in the campaign on the English channel. Thereafter, it was used in
    the Mediterranean fronts, especially in North Africa, the Balkans and Greece. A total of 560
    were built.
    Top speed 456 km/h
    Ceiling 8100 m
    Typical bomb load 1100kg
    Fairey Swordfish
    The Swordfish was a bomber and torpedo bomber aircraft adopted by the Fleet Air Arm in
    WWII. Known as the "Stringbag", it was designed in 1934, and was outdated at the beginning
    of WWII, but still was the main carrier borne attack aircraft of the FAA, achieving great
    successes including the raid at Taranto and the torpedoing of the Bismarck. It remained in
    service up to the end of the war, though relegated to anti-submarine role.
    The Mk.I version of the aircraft could carry up to 700kg bombs, depth charges, flares or a
    torpedo. MKII version (not modelled) could also carry rockets. Armament was a fixed forward
    firing 0.303 cal. Browning machine gun and a rear flexible 0.303 cal. Vickers K machine gun.
    Crew was of three (Pilot, Navigator and Telegraphist/Air Gunner) but could be reduced to two
    when carrying an additional fuel tank (not modelled).
    Top speed was 224 Km/h at 1500m.
    Implementation in Il-2
    In this patch, Mk.I version is modelled.
    Reggiane Re.2002
    The Reggiane 2002 was an evolution of the Re.2000 - Re.2001 family that mounted the more
    powerful Piaggio XIX and was designed as a fighter bomber and dive bomber. It saw
    operational service in 1943 against the Allied invasion of Sicily and mainland Italy. It was also
    adopted by the Luftwaffe and used in France against Maquis (partisans) forces.
    The Re.2002 did not have the "wet wing" of the Re.2000, but the more conventional wing from
    the Re.2001. It could carry a variety of bombloads, including an armour piercing 630kg bomb
    (derived from a 381mm naval artillery shell) and a small torpedo. It was also one of the few
    22 / 35
    Italian planes that could be equipped with an external fuel tank.
    The performance was very similar to the Re.2000, the Re.2002 just being slightly faster.
    Implementation in Il-2
    The first production series is implemented in IL-2. A subsequent variant had a slightly lowered
    engine mount and more refine cowling (for better pilot visibility) but was otherwise the same.
    Polikarpov R-5
    The Polikarpov R-5 was a Soviet reconnaissance bomber aircraft of the 1930s. It was the
    standard light bomber and reconnaissance aircraft with the Soviet Air Force for much of the
    1930s, while also being used heavily as a civilian light transport, in the order of 7,000 being
    built in total.
    The R-5 was developed by the design bureau lead by Nikolai Nikolaevich Polikarpov as a
    replacement for the R-1, the copy of the Airco DH.9A which served as the standard
    reconnaissance and light bomber aircraft with the Soviet Air Force.
    The prototype first flew in autumn 1928, powered by an imported German BMW VI V-12
    engine. It was an unequal span single bay biplane of mainly wooden construction. After
    extensive evaluation, the R-5 entered production in 1930, powered by Mikulin M-17s, licence
    built copies of the BMW-VI, as a reconnaissance bomber. Further modified versions were
    produced to serve as floatplanes, ground attack aircraft and civil transports.
    The R-5SSS, an improved reconnaissance bomber with improved streamlining, served as the
    basis for the Polikarpov R-Z, which succeeded the R-5 in production.
    Fiat G.55 Sottoserie 0
    Fiat G.55 Centauro was a development of the previous G.50 Freccia fighter. Besides improved
    aerodynamics it featured the 1475hp Daimler-Benz DB 605A piston engine (which Fiat
    manufactured under licence as the RC.58 Tifone). The first of three prototypes (MM491) were
    flown on 30 April 1942. The type was ordered into production, but only 16 G.55 Sottoserie 0
    (pre-production model) and 15 G.55 Serie I were delivered to the Regia Aeronautica (RA)
    before the armistice in September 1943.
    The pre-production planes were armed with one 20mm Mauser MG 151/20 cannon firing
    through the spinner and four 12.7mm Breda-SAFAT machine-guns around the nose while the
    production model had three 20mm cannons (two in the wings) and two machine-guns in the
    nose.
    Weapon Changes
    Fritz X
    This weapon (known with other alternate names: Ruhrstahl SD 1400 X, Kramer X-1, PC 1400X
    or FX 1400) was a guided anti-shipping bomb. It was designed to attack warship and other
    well protected ships. This bomb was derived from a PC-1400 armour piercing bomb, by adding
    a more refined nose, movable fins and tail planes. The bomb was dropped from high altitude
    from an aircraft, then remotely guided by the operator on the same aircraft that dropped it,
    using radio signals. The bomb had remote-controlled fins to adjust its trajectory, but had no
    engine. A couple of flares (various colours were used, light blue was found to be the most
    suitable) fitted on the bomb’s tail helped the operator to keep in sight the bomb and guide it,
    by keeping the flares just over the target. A minimum height of 4000m was needed for
    properly guiding the bomb to the target.
    23 / 35
    Attack by human pilot
    Proceed as a normal high level attack. Minimum height is 4000m, more is better. Acquire and
    track the target using the bombsight. You can either drop the bomb using the bombsight
    automation, or drop manually at an angle of about 30-35 degrees. Immediately after the bomb
    has been dropped, throttle down the plane to slow it down (you can even use combat flaps)
    and tilt down the bombsight (using the usual bombsight elevation keys) so that the bomb
    comes into sight. Then use bombsight velocity keys to move the bomb up/down, bombsight
    side-slip keys to move the bomb right/left. Put the bomb's flares exactly over the target and
    keep them there until bomb impact. Use gentle control inputs, the bomb responds slowly to
    operators command. You can easily overshoot your target if you aren’t careful in your control
    inputs.
    Applying guidance corrections will slightly slow down the bomb so you should not try extreme
    maneuvers; moreover, being a gliding bomb, not a rocket, it can receive only a limited amount
    of correction. You have to launch from a correct position so that you will need minimal
    guidance to hit the target.
    You can control only a single Fritz X bomb at a time. If you drop a second bomb while the first
    one is still in the air, it will not be controlled until the first one impacts. It is advised to make a
    second bomb run to drop the second bomb (if available). This means that you need to use
    manual bomb drop (not bombsight automation) to drop a single bomb at a time if you have a
    bomb load of two.
    Attack by AI
    Plan as a normal high-altitude bomb run, setting the ship as a target. Allow enough height for
    proper guiding (4000m or more). AI will apply corrections to hit the target (even if moving),
    better AI skill will give better guidance and an improved chance of hitting.
    Henschel Hs 293
    Only a rocket at a time can be guided by each player or by each AI plane. Applying guidance
    corrections will slightly slow down the rocket so you should not try extreme maneuvers.
    Instead launch from correct position so that the bomb needs only minimal guidance to hit the
    target.
    Operational range of the rocket at various heights was as follows:
    at 2.2 km altitude: 4.0 km
    at 4.0 km altitude: 5.5 km
    at 5.0 km altitude: 8.5 km
    Attack by AI
    The AI should begin an attack from an altitude of 3000m or more with the drop point set a few
    kilometers away from the target ship (see range table). If dropped from too low height the
    rocket might not be able to reach the ship and might fall into the water.
    AI will apply corrections to hit the target (even if moving), better AI skill will give better
    guidance and so improved chance of hitting.
    Bat radar-guided bomb
    The SWOD Mark 9, also known as Bat, was an anti-shipping weapon developed by US Naval
    Bureau of Ordnance's. It was fielded operationally and was one of the most impressive guided
    weapons developed during World War II.
    The Bat's guidance system was particularly sophisticated for the time. After being dropped it
    glided toward the target on a preset course using a gyro-stabilizer system to keep it on track.
    As it approached the target the bomb locked on with its own radar system that guided it into
    the target. Since the radar seeker was conceptually similar to the "sonar" system used by a
    24 / 35
    bat to prey on flying insects, the weapon was named after the bat. The Bat also included a
    self-destruct mechanism to keep it from falling into enemy hands, and obtained its electrical
    power from four small windmill generators.
    The Bat was put into operation in May 1945, on Navy PB4Y-2 Privateer patrol bombers,
    maritime derivatives of the Consolidated B-24 Liberator. One Bat was carried under each wing.
    Privateer’s crews claimed many successes against Japanese shipping in the seas around
    Borneo, though some sources suggest they may have exaggerated the weapon's effectiveness.
    Bats with modified guidance systems were also used against ground targets in Burma and
    other Japanese-held areas; they simply homed in on the biggest target in their radar seeker.
    Also other aircraft were modified to be equipped of the new bomb: F4U-4 Corsair, SB2C
    Helldiver, PBM Mariner, JM-1 Marauder, PV-1 Hudson and PB-1 Flying Fortress.
    Implementation in Il-2
    This bomb is fitted on F4U-1D (flyable) and B-24 (AI). Once dropped, it will lock on the best
    naval target that it finds. A radar seeker is simulated, looking forward and slightly tilted
    towards the ground. You should be sure to point the aircraft roughly towards the target, but
    also that there are no other ships around nearer or much bigger which the seeker might lock
    onto instead of the one you chose to attack. The bomb does not recognize friend from foe so
    be sure that there are no friendly ships in front of you or directly below you that the seeker
    could acquire as targets!
    The weapon will lock more easily and will be more precise against a big ship, that gives a
    strong radar return, than against a small ship or boat. Once the bomb is dropped, you do not
    have to do anything else, it is a "fire and forget" weapon. But (as for other weapons in IL-2)
    you must remain alive in game to score a hit.
    Range depends on aircraft altitude (being a gliding bomb) you can expect to achieve a 20km
    range if you drop from 8000m.
    Important: To maintain the online gameplay balance, the Bat bomb is not available unless
    mission builder explicitly enables it by setting mission date to year 1946.
    Razon Guided Bomb
    The Azon series were the first US guided bombs to be used operationally. These were
    conceptually very similar to the German Fritz X. The Azon bomb could only be steered in
    azimuth and thus it range error on delivery was similar to a dumb bomb.
    The Azon kit was produced until November 1944 by which time 15,000 units were built. It was
    deployed in the ETO from February 1944 and used extensively in Burma for bridge dropping
    strikes. The 15th AF in the Mediterranean is credited with Azon attacks on the Danube river
    locks and the Avisio viaduct. In Burma Azons were used to destroy 27 bridges using 493
    rounds, including the famous Kwai River bridge.
    The more sophisticated Razon used a dual channel control link for range and azimuth
    guidance. The VB-3 was based on the 1,000 lb and VB-4 the 2,000 lb bombs. The Razons used
    two tandem annular wing assemblies, the aft assembly used for control. The guidance
    command link used up to 47 preset channels. Around 3,000 Razons were built during 1945 but
    the weapon did not see significant use until the Korean conflict where B-29s carrying up to 8
    rounds were use to attack bridges.
    Implementation in Il-2
    For better gameplay, the more sophisticated Razon has been implemented and fitted to B-24.
    Bomb Fusing
    Real life bombs have generally an electrical or mechanical time fuse to avoid premature
    explosion in case of mishap (e.g. a bomb detaching from the aircraft while still on the runway,
    25 / 35
    or a bomb hitting the bomb rack due to turbulence). This has been implemented in IL-2, so
    that bombs now have a 2 seconds time fusing. If the bomb hits the target before that time,
    the fuse does not activate and the bomb does not explode. This means that in level flight a
    bomb must be dropped from a minimum altitude of about 25 meters to explode. If the bomb is
    dropped in a dive the altitude must be proportionally greater. This also applies to skip
    bombing: the bomb must be dropped from at least 25m and must not hit the ship before 2
    seconds.
    Realistic Torpedoes
    WWII aerial torpedoes were delicate equipment that needed be dropped with some
    precautions. Each torpedo type had an optimum altitude and speed of drop that allowed it to
    hit the water with a determined, optimum angle. If the angle was bigger, the torpedo tended
    to sink. If it was smaller, it did not enter the water and skipped on the surface. Also, the
    torpedo could not be dropped from too high altitude, because if it impacted the water too
    hard, its internal mechanism could be damaged.
    Each torpedo type in IL-2 has its optimum drop parameters, of course some error is allowed,
    but not too much.
    • LT F5W (Italian Whitehead)
    100m, 300Km/h
    • LT F5B
    40m, 250Km/h
    • Mk13, Mk13a
    30m, 205 km/h
    • Mk13 late
    180m, 400 km/h
    (this torpedo had a much wider range of drop than the early one)
    • Type91
    30m, 240 Km/h
    • Type91 late
    60m, 330 km/h
    (this torpedo had a much wider range of drop than the early one)
    • 45-17
    30m, 205 km/h
    Also torpedoes had to run for some time into the water to arm their warhead, so torpedoes
    cannot be dropped too close to the ship (distance should be bigger tan 400-600 meters).
    Torpedoes dropped on ground or directly on the ship (without hitting water) will not explode.
    Circling Torpedoes
    This patch also brings two new examples of torpedoes which are circling torpedoes that had to
    be dropped from a safe height in areas such as harbours that were crowded with enemy ships.
    These torpedoes run in circles for some time, if no ship was hit they self-destroyed.
    Motobomba FFF and 45-36AV-A are the circling torpedoes implemented in IL-2.
    Motobomba FFF (LT 350)
    This weapon was designed by Italian designers Frefi, Filpa and Fiore (hence the name FFF).
    The FFF was a 500 millimeters (20 in) diameter electric torpedo. It was dropped from high
    altitude, a first small parachute was used to stabilize and keep a low fall velocity; around 200
    m of height, a bigger parachute deployed, to assure a softer impact into water. The torpedo
    26 / 35
    was designed to steer concentric spirals until it found a target. It weighed 350 kilograms, and
    contained a 120 kilograms warhead. Its speed was about 15 knots and it had an endurance of
    15–30 minutes.
    The FFF was used in small numbers and without success against Gibraltar, Alexandria and
    during convoy battles in August 1942. Later it was adopted by the Germans as the LT 350 and,
    used in larger numbers. It scored some successes against moored ships at Tripoli, Bone and
    Bari.
    45-36AV-A
    This Russian torpedo was based on submarine torpedo 45-36 (which in turn was based on
    Fiume design). Adopted in 1939, it had a speed of 39 knots and a range of 4km. Drop height
    was about 2000-3000m.
    Torpedo-Kommandogerδt
    ToKG device is like a simplified torpedo data computer found in submarines. ToKG sets the
    torpedo gyro angle which turns the torpedo once it enters the water. For example angle +30
    would turn the torpedo 30 degrees to right. ToKG needs two input parameters from the player.
    Target ship’s speed in knots and ship’s AoB (Angle-on-Bow).
    ToKG is used with the old bombsight speed & side slip keys. Speed keys are used to input
    target ship’s speed in knots to ToKG. Side slip keys are used to input ship’s AoB (Angle-on-
    Bow).
    Optional spread parameter can also be adjusted with bombsight angle keys. Increasing spread
    angle means that torpedoes will have different paths and therefore chances of hit can increase.
    Setting a spread of 6° means that left side torpedo will curve 3° to left and right side torpedo
    will curve 3° to right.
    The idea of the ToKG is to input these two parameters to the device which then calculates a
    correct torpedo gyro angle and feeds it to the torpedo. This way the pilot doesn’t need to
    estimate the angle and steer plane to take needed lead before the torpedo is released. With
    ToKG the pilot always aims the plane directly towards the target ship.
    Anyone who has played submarine simulations, knows that besides target ship’s speed and
    AoB, distance to the ship has also some effect to the torpedo gyro angle. However when the
    distance changes, angle remains somewhat constant. The optimum torpedo release distance
    for ToKG use is 2000 meters from the ship.
    ToKG can be found from Ju 88A-4/Torp, Ju 88A-17 and He 111H-6 when torpedoes are
    carried.
    27 / 35
    Navigation Improvements
    Situation pre-4.10
    Before the 4.10 patch, balance between playability and realism was such that the waypoints in
    mission acted as sort of "virtual radio beacons" and repeater compass had a needle which
    pointed towards the next waypoint. This obviously has two issues. These waypoint virtual
    beacons could be located in too favorable and unrealistic positions such as middle of ocean or
    deep within enemy territory. Also most of the repeater compasses worked like radio
    compasses which they didn't do in real life. Programmable waypoints for aircraft would be
    post-WW2 technology.
    Realistic Navigation Difficulty option
    Team Daidalos added a new difficulty option to enable more realistic navigation. When this
    difficulty option is turned on, all new navigation objects become functional and certain
    instruments in cockpits work in a different way. When the difficulty option is turned off,
    everything works as before 4.10 patch.
    Instrument Changes when Realistic Navigation option is turned on
    All repeater compasses stop working as radio compass. Currently there are several navigation
    instruments in game which give too much information for player. For example the standard
    Luftwaffe & US repeater compasses work like radio compass pointing towards next waypoint.
    In real life these instruments didn't have any direction finding (D/F) ability. In order to have
    this, the plane needs a D/F-loop antenna.
    Manually heading indicators in repeater compasses are adjustable with two new keys. In
    Luftwaffe compasses this indicator is the circular compass rose while the plane icon indicates
    magnetic heading. In US compass this indicator is the double line heading indicator which
    previously was pointing to waypoint. Purpose of these manually adjusted indicators is simply
    "marking" a selected heading so that it's easier to maintain. Map the two new keys (Compass
    Heading Plus/Minus) to adjust heading indicators.
    RFD (radio direction finding) instruments are operational. In Luftwaffe planes this means that
    AFN-1 & AFN-2 instruments that have been static before becomes functional. Similar
    instruments in other planes are working also as expected.
    Planes that have a real radio compass (rotating D/F-loop), such as B-25, Bf 110, Ju 88,
    Beaufighter etc. have their radio compasses working as expected, indicating relative bearings
    to selected non-directional beacons. Only automatic mode for the radio compasses is currently
    supported but we plan to add manual mode later.
    In Russian planes the RDF instruments are removed IF the plane doesn't have D/F-loop.
    According to our current knowledge, many Russian fighters had an option to install direction
    finding equipment, but they didn't have these installed.
    Radio Direction Finder Basics
    A radio direction finder (RDF) is a device for finding the direction to a radio source. Due to
    radio's ability to travel very long distances and "over the horizon", it makes a particularly good
    navigation system for ships and aircraft.
    Radio direction finding works by comparing the signal strength of a directional antenna
    pointing in different directions. At first, this system was used by land and marine-based radio
    operators, using a simple rotating loop antenna linked to a degree indicator. This system was
    later adopted for both ships and aircraft, and was widely used in the 1930s and 1940s. On pre-
    World War II aircraft, RDF antennas are easy to identify as the circular loops mounted above
    28 / 35
    or below the fuselage. Later loop antenna designs were enclosed in a aerodynamic, teardropshaped
    fairing.
    The basis for operation of all radio direction finders is that the maximum signal will be received
    when a loop antenna is aligned in the direction of the radiated signal. The corollary is that a
    minimum signal, or null, occurs when the loop antenna is at right angles to the direction of the
    radiated signal. In practice, however, the position of minimum signal is used because it can be
    more accurately determined than a maximum.
    Instruments
    Luftwaffe AFN-1 and AFN-2 instruments
    These instruments have two different modes. In homing mode, the vertical needle indicates
    horizontal deviation of plane's heading related to a beacon. In other words when plane if
    flying straight towards or away from a non-directional beacon (NDB), the needle is centered.
    In blind landing mode the vertical needle show horizontal deviation from the Lorenz beam's
    center-line (see Lorenz blind landing beacon for more details). Horizontal needle always shows
    the received signal strength, which roughly correlates with range to beacon.
    The important thing to notice is that the nature of fixed D/F-loop antenna is such that it cannot
    tell if the beacon is directly ahead or directly behind. In both cases the vertical needle is
    centered. The pilot must notice this from instrument behavior. When flying towards the
    beacon, vertical needle works in a "showing" manner, i.e. it shows the direction of the error.
    So pilot must turn away from the direction needle points to. When flying away from beacon,
    the needle works in "commanding" manner, i.e. it shows the direction in which the correction
    must be made.
    If it is not known whether pilot is flying towards or away from the beacon, this can be solved
    with "rudder test". Press left rudder pedal completely down and observe how the vertical
    needle swings. If the needle "follows" the pedal (swings left), plane is flying towards beacon. if
    it swings to the right, plane is flying away from beacon.
    Other similar indicators
    Basic functionality of the Russian ???-2, ???-10 and Japanese homing instruments is basically
    same as AFN-1 & AFN-2 vertical needle except the needle moves in the inverted way -
    "commanding" manner when the plane is flying towards beacon and "showing" manner when
    the plane is flying away from beacon.
    29 / 35
    Radio Compass
    A few planes in game like Ju 88, Beaufighter, B-25, Bf 110 have radio compasses. These
    planes have D/F-loops that are rotate by motor automatically to the direction from where the
    beacon signal is coming from. Antenna rotation angle is then shown to the pilot or radio
    operator as a needle position on radio compass instrument.
    New Navigation Objects
    Non-Directional Beacon Object (NDB)
    NDB is a new stationary radio beacon object that can be placed on map. When Realistic
    Navigation difficulty option is enabled all navigation instruments work only with beacons and
    not with waypoints anymore. Waypoints are still there as usual but they are just abstract
    points on the map and instruments don't know anything about these.
    The NDB is basically a simple transmitter radiating an omni-directional signal which is
    modulated at intervals with the identification code. Each beacon is given an unique two letter
    ID. Friendly beacon icons & IDs are always visible in map and briefing screen since their
    positions are known. The pilot has two new keys: Next Beacon & Previous Beacon. These keys
    are used to tune the radio to the selected beacon frequency (based on ID). The beacon will
    broadcast its ID as Morse code once a minute so pilot can hear if he is tuned to the correct
    beacon. Also the pilot can hear a static (chirring) background noise when a beacon is
    transmitting constantly but there is no modulated signal. The cone of silence is also included
    so the pilot knows when he has flown directly over the beacon (signal suddenly drops to zero).
    AM Radio Station Objects
    As the commercial medium wave (AM) broadcast band lies within the frequency capability of
    most RDF equipment, these stations can also be used for navigation just like NDBs. One of the
    first RDF developments in the early 20th century was that aircraft used commercial AM radio
    stations for navigation. This continued until the early 1960s when VOR (VHF omni-directional
    range) systems finally became widespread.
    4.10 patch includes several historical radio station objects with generic looking antenna
    towers. These are used exactly like the NDBs, but instead of static noise & Morse code, player
    can hear music, speech, etc. These audio samples that the radio station plays are placed at
    certain folders under "samples\Music\Radio". For example if mission builder places "Radio
    Honolulu" radio tower to mission, this station would play audio samples from folder
    "samples\Music\Radio\Radio_Honolulu". Since the missions can contain date information in
    4.10, it is possible to use date folder inside radio station folder. For example folder
    "samples\Music\Radio\Radio_Honolulu\19411207" could contain audio samples for Pearl
    Harbor attack mission and these would be played only if mission date is December 7, 1941.
    It's also possible to use "X" in place of day, month or year. For example "1940XXXX" would

    date folder given. Audio samples must be the same standard format (Mp3 with RIFF header
    and wav extension) as all other audio clips.
    Meacon Object (Masking Beacon)
    Meacons were trick to render beacons less usable for the enemy. Meacon basically captures
    30 / 35
    enemy beacon signal and re-radiates the same signal from different location. Therefore
    confusing the enemy trying to use it's own beacons for navigating. This is a stationary object
    like the NDB.
    YE "Hayrake" Directional Beacon
    The ZB/YE system (nicknamed Hayrake) that the allies used was method of finding a way back
    home to the aircraft carrier. This system was classified until 1947. ZB is the receiver adapter in
    aircraft, working on top of the regular radio receiver. YE is the rotating directional beacon
    installed to allied aircraft carriers.
    The carrier sent out a Morse code letter for every of 30 degrees of the carrier's compass
    direction points synchronized with the position of a rotating antenna. The coded letters for
    each of the twelve compass points were changed each day and sent as modulated Morse code
    tones. The code was modulated in the lower part of the broadcast band. That broadcast band
    RF signal was then used to further modulate the 234 to 258 Megahertz VHF signal. The VHF
    signal was mostly line-of-sight. If the pilot could hear two Morse code letters, he would know
    his relative position to the carrier. The double modulation would make it difficult for an enemy
    to easily detect the Morse content of the signal. The VHF signal was reportedly reliable to
    about 40 to 70 miles out for an aircraft at 10,000 feet and further at higher altitudes.
    In game YE beacon works following way. Root of the orders menu (tab-key by default) includes
    details of all friendly "hayrake" carriers. For example:
    ID:FC USS Lexington CV2 ( EWR / KPT / VXZ / ADF )
    Code after the carrier name is the Morse code pattern that the YE sends to different directions.
    Each letter in code represents 30°. segment starting from 0°. For example carrier transmits K
    to 90-120°. So pilot hears K (dash dot dash), the carrier is at bearing 270-300°.
    Pilot will use the Next Beacon & Previous Beacon keys to tune the ZB receiver to carrier's YE
    frequency (based on ID). If pilot is within the range of the YE beacon, he will hear Morse code
    about twice in a minute since the carrier's YE antenna rotates at 2 RPM. Carrier sends the
    bearing Morse code for 9 antenna revolutions. This bearing Morse letter is always sent twice in
    a row for better clarity. During 10th revolution, carrier sends it's own ID code and after that
    the same cycle starts again. Bearing code is randomly generated, but still same for all online
    players.
    “Hayrake pie” example:
    Code is same as above:
    EWR / KPT / VXZ / ADF
    Aircraft at position 1. would hear Morse
    code “KK”. Pilot can determine that the
    carrier is at bearing 270-300°
    Aircraft at position 2. would hear Morse
    code “VX” because it is located between
    two segments. Pilot can determine that
    the carrier is at bearing 30°.
    Aircraft at position 3. would hear Morse
    code “DD”. Pilot can determine that the
    carrier is at bearing 120-150°
    31 / 35
    Only USN, USAF, RN and RAAF planes carry ZB receivers. IJN aircraft carriers have normal
    NDBs, since Zeros & Vals have fixed D/F-loops and homing indicators. According to our current
    knowledge, the Axis didn't have a similar system in use.
    YG Directional Beacon
    YG was simplified version of the YE which was used on land. This is a stationary ground object
    like the NDB that can be placed on ground and is always visible in map & briefing screen with
    ID. Functionality is same as with YE, except the code is always fixed and same for all beacons.
    Carrier's YE code was changed daily in order to protect the carrier in case enemy would have
    found out the code.
    The fixed code of YG beacon is
    DWR / KAN / UGM / LFS
    The following historical ditty was used to remember the code:
    "Did Willie Really Kill A Nasty Ugly German Man Last Friday or Saturday."
    Lorenz Blind-Landing Beacon
    This is a similar stationary object like the NDB beacon. It must be placed certain way at
    airports in order to work correctly. The object must be placed at the far end of the runway
    viewed from landing plane. Also the red/green guide arrows must be aligned with the runway
    and green arrow must be pointing to the planes landing direction. When the Lorenz beacon is
    placed this way the marker beacons are automatically at their correct places (although not
    visible). The Lorenz beacon is selected same way as NDB. The pilot uses the Next Beacon &
    Previous Beacon keys to tune to correct frequency.
    Following image shows the placement of Lorenz beacon for standard length runways. Another
    Lorenz object for longer runways is included with stationary objects.
    Aircraft approaching the runway in dark or bad weather would tune their blind landing receiver
    to the broadcast frequency and listen for the signal. If they heard a series of dots, they knew
    they were off the runway center-line to the left (the dot-sector) and had to turn to the right to
    line up with the runway. If they were off to the right, they would hear a series of dashes
    instead (the dash-sector), and turned left. Key to the easy operation of the system was an
    area in the middle where the two signals overlapped, where the dots of the one signal "filled
    in" the dashes of the other, resulting in a steady tone known as the equi-signal. By adjusting
    their path until they heard the equi-signal, the pilot could align their aircraft with the runway
    for landing.
    Two small marker beacons were also used with Lorenz: one 300 m off the end of runway, the
    HEZ, and another 3 km away, the VEZ, modulated at 1700 and 700 Hz, respectively. These
    32 / 35
    signals were broadcast directly upward and would be heard briefly as the aircraft flew over
    them. To approach the runway the aircraft would fly to a published altitude and then use the
    main directional signals to line up with the runway and started flying toward it. When they flew
    over the VEZ they would start descending on a standard glide slope, continuing to land or
    abort at the HEZ depending on whether they could or couldn't see the runway.
    Many Luftwaffe planes have a combined blind landing & homing instrument AFN-1 or AFN-2 to
    show a visual indication of the Lorenz beam & markers. They are fully functional with Lorenz
    blind landing beacon. The vertical needle of the AFN instrument shows the deviation from the
    beam center line. The horizontal needle shows the signal strength which roughly correlates
    with range to beacon. If you hear series of dots and AFN needle points to left, you are too far
    to the left of the beam's center line. If you hear series of dashes and AFN needle points to
    right, you are too far to the right from the center line. At center, the dots and dashes merge
    into solid signal.
    The B-25 has ILS instrument which is much like the German counterpart, except that it's
    horizontal needle shows whether plane is above or below correct glide path. This instrument
    doesn't work with Lorenz beacon. It needs the Army Air Force Instrument Approach System
    beacon to work correctly.
    To practice blind landings, try the missions found from Single Player -&gt; Germany -&gt; Bf 110 G-
    2.
    RDF Equipment Limitations
    Typical single engined one man fighter carries only one radio which could be tuned to only a
    single frequency at a time. This would mean that pilot could either talk to his squadron/ground
    control OR use the radio for homing. For example the typical Luftwaffe fighter radio FuG 16Z
    has ZF-FT toggle switch which is used to select either homing mode or voice communication
    mode (ZF= Zielflug, FT=Funktelegraphie).
    This limitation is presented in IL-2 such way that if player is flying such plane with single radio
    equipment and using it in homing mode, he cannot receive any voice radio communication. If
    player tries to access orders menu, it's printed with gray font to indicate that voice
    communication is disabled. Player can still issue orders, but this switches the homing mode off
    automatically.
    Bigger planes with several radios and dedicated radio operators don't have this limitation. ZB
    receiver doesn't suffer from this limitation since it's working on top of the voice communication
    broadcast band. Also blind landing is not affected, since planes have separate blind landing
    receivers.
    Radio Propagation Model
    Radio propagation is the behavior of radio waves when they are transmitted, or propagated
    from one point on the Earth to another, or into various parts of the atmosphere. Modeling a
    accurate radio propagation for IL-2 would be consuming PC resources way too much, so Team
    Daidalos developed a very simplified radio propagation model for 4.10.
    Main problem with simulating radio propagation for IL-2 is that the IL-2 world is flat. One of
    the main characteristics of radio signal is how well it can travel over the horizon and follow
    earth's curvature. This is solved in 4.10 by calculating all signal propagation simulating earth's
    curvature. Also signal attenuation is calculated when it faces ground obstacles such as hills &
    mountains. This simplified propagation model is needed to prevent player from gaining too
    much benefit from radio navigation. For example if player is flying very low and far away from
    aircraft carrier, he cannot receive carrier's YE signal since it's VHF signal is blocked by earth's
    curvature.
    33 / 35
    Characteristics of Navigation Aids
    NDB:
    • Low Frequency
    • Follows earth's curvature very well as ground wave
    • Travels over the horizon very well
    • Low signal attenuation when facing ground obstacles
    • Low ionospheric refraction at night increases the range slightly
    AM radio station:
    • Medium frequency
    • Follows earth's curvature as ground wave
    • Travels over the horizon fairly well
    • Medium signal attenuation when facing ground obstacles
    • Ionospheric refraction at night increases the range a lot
    YE & YG beacons:
    • Very High Frequency
    • Mainly line of sight propagation.
    • Doesn't travel much over the horizon.
    • High signal attenuation when facing ground obstacles
    Pilots using radio navigation should be aware of the different effects that may cause incorrect
    indications. A pilot should be able to identify these situations and realize that the RFD
    indication cannot be fully trusted and another means of navigation should be used.
    Night Effect
    Radio waves take two paths to the radio compass receiver. The first and normal path is along
    the earth’s surface. If only these waves were received, the compass would point directly to the
    NDB. The second path is via one or more wave refracting layers above the earth (the
    ionosphere) returning to earth to mix with direct waves. Complete changes in the nature of the
    waves take place on this path and produce errors in direction.
    The ratio of the intensity of indirect to direct waves in the total received signal determines the
    liability of error of the radio compass. As the strength of the indirect waves is far greater at
    night, errors then are more common and of greater magnitude: this is called ‘night effect’.
    Often this effect is more pronounced within an hour of sunrise or sunset, when the changes in
    the state of ionization of the upper atmosphere are particularly violent.
    The night time range of an NDB is only dependable over distances where the ground wave
    transmission predominates, which is approximately 60 miles over land and 100 miles over sea
    under reasonable propagating conditions. As the distance increases the ratio of indirect to
    direct waves will increase and bearing indications will become erratic. Treat with caution NDB
    reception beyond these ranges.
    Mountain Effect
    Sometimes an effect similar to night effect is obtained in mountainous areas where the energy
    received from an NDB consists of two or more waves, one of them direct and others by
    reflection from the mountains. Bearing indications are found to change rapidly until the
    affected area is passed.
    Terrain Effect
    The useful range of an NDB is influenced by the type of terrain over which the radio wave
    travels. It is greatest over the sea and least over sandy or mountainous country, and an NDB
    with a daylight range of 200 miles over the sea may only have a range of little more than 50
    miles over unfavorable types of land. Therefore, when an NDB is located on the coastline, its
    range in different directions can be expected to vary considerably.
    34 / 35
    Height Effect
    The range of an NDB over the sea is relatively independent of aircraft height. Over unfavorable
    terrain it increases considerably with height.
    Thunderstorms
    A thunderstorm generates a tremendous amount of radio frequency energy and when the
    aircraft is near to a storm center the radio compass may show some interference.
    Other Features
    Ships
    All ships, excluding some very small ones (landing craft), are now modelled as "big ships" so
    they have bow wave effect and can be damaged concurrently by players in the network.
    All ships and particularly submerged submarines are now more vulnerable to close bomb hits.
    Big ships also have a revised damage model so that, if they are hit at a vital point, their
    maximum achievable speed is reduced due to that damage.
    Smoke from ships smokestacks is now visible from longer distance.
    Using Runway Lights
    Using the static light objects for runway lights is nothing new in IL-2. However, previously the
    lights were always lit so it was not possible to use there as realistic war-time runway lights,
    which would be switched on only when plane was coming in to land.
    Static lights objects are changed so that now they can have an "owner", either red army or
    blue army. When runway lights are assigned to an army they're turned off by default. Placing
    blue lights at blue airport makes them usable by blue player. Lights with neutral army are
    always lit.
    When the player is coming to a landing during night he can request runway lights to be turned
    on. This is done with a new command "Request Runway Lights" which can be found from the
    old "Ground Control" commands menu. The player needs to be close enough and there cannot
    be any enemy activity near the airfield. Otherwise the ground control refuses to switch on the
    lights.
    Ground control will switch off the lights automatically when they see that the player has
    landed.
    Jettison Stores
    The jettison stores feature allows player to drop bombs, torpedoes, Wfr.Gr. 21 rockets and BK
    7.5 on Hs 129. Bombs are dropped without arming them so it’s safe to drop them at any
    altitude. This feature has a new command in controls menu which needs to be mapped to a
    key. Old fuel tank jettison feature remains as it was before.
    Player Name & Callsign Filtering
    Server can filter out all non-latin & non-cyrillic characters from players name & callsign by
    adding filterUserNames=1 to the [NET] section of conf.ini.

    WOW, some changes in the AI and pilot surivability could almost redefine the experience!
    I can see-for example- the Mustangs becoming much more deadly when spraying an enemy fighter with .50s.

    Or expect gunners to be "disabled" more often ! This is going to be great anyway!

    It certainly does, I have a lot of experience with freight train acceleration and the Fw most certainly beats it.
