I am interested in how IL2 1946 models the atmosphere, especially how the game derives TAS. Is, for example, air temperature (and its effect on air density) taken into consideration?

Right now I use the '2%-rule of thumb' to derive my TAS (from IAS and altitude above sealevel) which says that TAS increases by 2% every 300 meters of altitude. Well, that is just a rule of thumb...
When dropping bombs with the Pe-2 (OPB-1 bombsight, no bombsight automation) it looks like the error made by this rule of thumb leads to quite incorrect bombsight-angles.
Some information on this topic would be greatly appreciated!

Don't forget unless you are level bombing at sea level you will have to +/- the targets terrain altitude from the bombsite altimeter setting, unless your using the Norden sight.

These might help you with your 2% calculation.

I'm creating a new chart for KPH as its a bit old n fuzzy, so bear with me. < (DONE)
