Hello Soldier_Fortune,

I am trying to find the formula IL2 uses for TAS calculation.

I spent the whole morning searching and reading the web and so far I can calculate temperature, pressure and density at the altitude, but I found no equation which would plug these to the TAS calculation.
(They always included other factors which circularly used TAS for their calculation)

Based on you example:

I suppose you have the ISA equation for TAS handy?
Would you be so kind and share it?
