IAS -> TAS air density model

Thanks a lot for the quick answers!

Now that is strange...
The 'wonder-woman-view' (no cockpit-view ) shows TAS, very interesting, I never used ww-view. I'll do some testing on this, outcome should be that IAS and TAS are the same at sealevel... very interesting and new information, thanks!
This should at least tell me if the TAS derived by IL2 differs from the TAS I derive.

Not sure what you mean with "unless your using the Norden sight". The target-altitude must not be subtracted from the bombers altitude when using this bombsight?

Thanks a lot for the TAS-charts! And also the smartphone-utility is very interesting, although I do not have such a new mobile phone.

In fact I made such a utility for the X52pro display myself, here are some pictures:













This little application does all the mathematics 'behind the scenes' and computes the bombsight-angle, also wind and the resulting side-slip (bombsight correction left/right) is taken care of.
The angles derived by this tool are quite accurate, I am just wondering if the formula (2% every 300m or 1000ft) I use to derive TAS (speed over ground in fact regarding wind) is 'good enough' for airspeed is the most critical parameter here. That is why I posted my question here, I thought that maybe someone with a deeper insight into the games functions could tell me how IL2 actually derives TAS...

Again, thanks a lot for your answers!
