I'm new to propeller driven aircrafts (except for Microsoft Flight Simulator, which I've only played for landscapes and navigation), so it seems to me that the tiny two pages of the manual do not teach me enough about the (military) in-game use of those (to me) new features:
- mixture
- supercharger
- radiator
- pitch
- variable pitch
- aeromechanical screw
- propeller feathering
- magneto
.........but http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif I've understood the use of extinguisher http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

are these parameters valuable into the sim?
in case: is there a link or a document where all these things are better explained?


thanks

Well, you could start at the manual in the PF folder for one http://forums.ubi.com/images/smilies/351.gif http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

However, there is an option in the Difficulties settings which disables complicated engine control. Its what I do, basically you don't have to do anythig, except open up the radiator once in a while so youre engine can cool down.

Hope it helped

For some real life information about forced induction, mixture control and propellor control systems, see the Engine Related Columns written by John Deakin at AvWeb. They are listed in the right hand side bar column at the index for his Pelican's Perch Column (http://www.avweb.com/news/columns/182146-1.html)

For instructions relating to a specific aircraft you'll have to tell us what you fly... http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Dont care about it. The so called CEM is a joke, e.g. the magnetos are absolut useless in FB/PF. If you want real CEM go to Target Rabaul.

A few brief principals on the R-2800 powered F4U...

This aircraft was fitted with an auto mixture control, a two stage, two speed supercharger and a constant speed (Hamilton Standard) prop.

So just leave it in auto rich, which would be appropriate for all but 'auto lean' cruise, which I don't think is modeled anyway. The supercharger is modeled with 'three stages', which is really modeling the second (aux) stage which could be selected (1) neutral (2)low speed (3) Hight speed. The speeds are selected as altitude increases. Neutral up to say 12,000ft, low to 18,000 ft or so and high above that. A guide for the real plane, for what works best in the game, you will have to experiment.

The prop (a problem) is supposed to be constant speed, reflected in the tachometer. Throttle is supposed to set manifold pressure and the 'prop pitch' a constant speed within it's operating range. HOWEVER.....

With prop pitch (in the game) selected to 100%, the engine should maintain 2700 RPM when throttled up above say 30% or so. However it appears that the manifold pressure and RPM in the GAME both move with the throttle, even at climb and cruise power settings. This is not correct. I am not convinced that the game designers and beta testers really understand how this system works.

For your purposes, 100% "pitch" (full RPM) for takeoff, reduce to say 90% for climb, 75% for cruise and use 90% for approach. 100% was not used on carrier approach as sudden application of waveoff power could overspeed the engine.

If this prop controll eventually gets corrected, then actual aircraft RPM values could be used for each stage of flight.

You will see that it is not that complicated once when you get some experience. Till that time, you must struggle a little. You may also choose some not-that-demanding-to-fly a/c's (like Me109, have a lot of that stuff on 'auto' http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif). That will help also.

About some specific stuff.. well there's no magic wand; you must get into our ride and explore all options. What is important is that you stuck with one ride at first and learn as much as you can.

Most types have auto mix - for the others you only have to step it down as you go to high altitude (over 3500m generally). You'll notice when this must be done as the engine begins to sputter and put out heaps of exhaust smoke.
There is also a small boost in power to be had by using 120% mix below ~500m.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>
- supercharger <HR></BLOCKQUOTE>

Capability varies between types (manual/auto, no of stages) . Higher stages should not be used at low altitude as they'll cause engine damage. There is an aircraft spec' doc on FB disc 2 that gives an engine settings summary for many types - otherwise refer to the PF readme file for some brief notes.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>

Heaps of discussion here about which settings are best etc etc. When cruising its probably a good idea to keep it open and then close it or use reduced setting during combat (Open increases drag)

Most types have constant speed units which automatically adjust to give best thrust for your chosen throttle/rpm setting. Lower pitch settings are used for fuel economy (not much of an issue in game) and prolonged steep dives. Again this topic gets discussed a lot around here. For the most part you can get away with just leaving this setting alone (though better performance can be achieved with skillful application).
<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>
- propeller feathering <HR></BLOCKQUOTE>
Only applicable to multi-engined types eg Bf110, P38, He111. Used to turn the blades of a disabled engine "edge on" to the wind - necessary to reduce drag from a windmilling prop. Note - you cannot unfeather a prop once set.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>
- magneto <HR></BLOCKQUOTE>

Not terribly significant in game - turning off the magnetos will stop the engine, turning off one of them will reduce power output. Most players never touch this (I don't even have a command set for it at the moment).

As noted by others what you need to manage varies with the plane - once you've messed around with it for a while you'll find its quite easy.
