I'm sorry, I do not find any original German manual / document where a Bf 109E was rated at 500 km/h (1,35 ata) at Sea Level.

Are those 500km/h at Sea Level mean TRUE AIRSPEED or Indicated AIRSPEED?

Are those 500km/h at Sea Level mean TRUE AIRSPEED or Indicated AIRSPEED?

True Air Speed.

[Kurfürst]

French trials at ca. 980 Hgmm. Works out as ca. 1.3ata (we have 1.35ata engined model, which has a bit more power)



Its seems the French measured about 487 km/h at ca. 250 m with 1.3ata on a E-3.

Maybe I misunderstand your question, but TAS=IAS at s.l.

Cheers,
Ins

even the spitfireperformance.com says BF109E should do around 560 max at level

http://www.spitfireperformance.com/spit1vrs109e.html

IAS and TAS almost the same at sea level.

@Kurfurst - I will test the Emils top level speed tonight and will post results here.....I doubt its only 470 kmh

I measured 460-470 near SL - as noted, it should be 500..

I did not test top speed (ie. at 5000m, where it should reach 570 kph TAS) because its impossible to test high altitude speed with reasonable accuracy. COD only shows IAS speed even in cocpit off mode, and the TAS/IAS conversion creates a too large margin of error to get accurate enough results, to draw any valid conclusions IMHO.

Maybe if the devs are feeling generous the FM and DM's will get a makeover but other than that the game is finished, to me Luthier as made it quite clear the future is BOM. CLOD was just a way to finance BOM.

I fear you are right, but hope you are wrong. This update left me feeling they have moved on. Hope I'm wrong. If you are right they've lost me as a customer for good. There is no way I would trust a company that takes your money and doesn't finish their work (especially as unfinished as CoD is). Not in my home or online.

Only a sucker would buy BoM if CoD doesn't get fixed.

As in the graphic engine module could be rewritten to incorporate new tech, without overly effecting all the other game engine modules. In Olegs first IL-2 game engine everything was mixed together so much that changing one thing caused major bugs, and problems in other code, features etc. Although it made it much harder for modders to hack the code. That isn't applicable this time as the developer is releasing the SDK.

Except, in 5 years these already not so fantastic graphics are going to look really dated. There is no future proofing in technology unless you are satisfied with the outdated, and most simmers are not.

@Kurfürst

Thank you for the detailed message.

With a little patience it is possible to reach such horizontal speeds at sea level with the BF109E-iL2CoD ... ...

By the way: the BF109E-iL2CoD is fitted with a 1200 PS machine.

Their decisions, their mistakes, their (possibile) bankrupt (although, russian sim "market" is big, *wink* *wink*)....btw, BOB theatre is well covered now with most (important) planes available (who participated in the BOB battle)...as onliner I dont care about offline campaigns but I feel your bitter....I hope they will optmise the graphics and to fine tune the FM and DM.
