hello, i;ve got 46 up and running with no issues but it seems the old handy heinkle bomb chart is way to slow for the arado zooming along at 500kph, anyone know the proper level bombing release speed and recoomended TAS to put into bombsight, i sued 400IAS kph and inputted 440kph TAS and hit city but missed the block...

am having no problemsd with glide/dive bombing as the sight works like the stuvi except no user inputs/horn.

a-20 is giving me some quirks, was using the mph but it seems patterned after b-25j so used the tables in b-25 bombsight and worked perfect, so i guess its in knots but we input mph ala b-25?

Either way tons of fun and even the TB-3 snap roll has been fixed.<div class="ev_tpc_signature">

Are you aware that there is a persistent bug in the program? When calculating TAS, the program makes a fault by about 10pct up or down. I always calulate the exact speed and keep on tweaking it so thath the sight keeps stationary above the target. I made my own bombsight table with M$ excel, I might adapt it to the AR-234 some day http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif<div class="ev_tpc_signature">

BTW, the bombsight refers to the curve the bombs make if they are released at a certain altitude with a certain (true) airspeed. Since the A-20 and B-25 are roughly the same aircraft in terms of operating ceiling and airspeed, one table works for both aircraft. And they both used the same bombs also. The arado is a great deal faster of course. The true airspeed increases by 2% for an altitude gain of 1000 feet. Altough this only goes for an airspeed below 400 km/h IIRC. This is due to compressibility of the air. This is disregarded for speeds under 400 km/h. But I don't know if Il-2 1946 models it, probably not.<div class="ev_tpc_signature">

theres no but with the arado..

just today i hit 3 A20 parked close from 1500M. with 500 km/h.. exatly where i aimed.

its a wonderful bomber.. if just those 20's were pointing forward instead of backwards.. no use<div class="ev_tpc_signature">

I havent really tried it yet, but does the Arado's bombsight tilt down?<div class="ev_tpc_signature">

In Il-2 1946, it is essentially the same sight as found in the He-111, Ju-88, B-25 and A-20C. But the Arado flies just a bit faster.<div class="ev_tpc_signature">

I thought the sight was similar to the stuvi?<div class="ev_tpc_signature">

ar234 has both sights. It has the dive sight like in JU88 and the level sight as in he111,b25,etc.. (use crew switch position to access the other set of sigts).

Not so sure that is a bug so much as an inability to alter altitude+speed of the sight in the sim by smaller incraments.......As to the bombsight tables, they are standard for "all" planes as it has nothing to do with the plane itself yet simply speed/altitude of the bomb dropped.

In truth I'd assume they are also simplified or we'd have to calculate air temperature, barometric pressure, cross/head/tail winds, weapon type (size/shape) etc. etc..

Yet with the stock tables I and a number of the guys from the squadron I'm in have no trouble dropping them from 4-5km. altitude and hitting "exactly" where we want......The biggest problem "lining up & eliminating yaw".....Your constant adjustments above compensating for those minor speed/alt. discrepencies.

One way around that though is quite simply go to a nominal altitude you can set, and reduce speed to a nominal amount as well.<div class="ev_tpc_signature">
