I'm also looking for the same info.
ROSS_YOUSS made IL2Compare and the data is in TAS, and allegedly this data was an output of the in-game polynomial. However, there is no update since 4.071m and so we have no definitive reference for performance of any of the new aircraft.
This is a problem for map makers, as players argue over performance of the new aircraft. Fw190A3 vs the Ic Fw190A4 is a good example.
Utilities such as LesniHU autopilot and UdpGraph permit speed tests to be carried out offline. I've been doing that under the following conditions: Crimea, 25%, rads closed, overheat off, unlimited fuel.
UdpGraph has two functions for the TAS calculation; TAS() takes arguments of IAS, altimeter, MSL pressure, MSL temp, and as Crimea is supposedly 745mmHG and 25 deg C, should be ideal. The other TAS function, TAS2(), takes arguments of IAS and altimeter only and outputs TAS assuming a standard atmosphere. Problem is, if you plug standard atmosphere arguments (763, 15) into TAS() it doenst give the same result as TAS2(), when it should. So it doesnt look like UdpGraph TAS() function is using the correct formula/polynomial. It's close, but exact would be nice.
There have been a few discussions over the years about the 'TAS formula' or 'polynomial' that is written into the game. The last poster confirmed that the atmosphere in game is 'non standard'. Now that the game has been opened up, it really should be possible for someone to post what the actual TAS formula/polynomial is, which takes the MSL pressure, and MSL temp arguments, so that direct comparisons can be made with IL2Compare data. Just post something we can paste into Excel. Please!
