True Altitude?

[FrankB]

Hi Soldier Fortune,

I did some tests using your formula to calculate TAS, but I still seem to have unsatisfactory results on winter maps.
In the past weeks I have learned how to use FMB to create custom mission for testing.

Test environment:
- stock 4.12.2
- SB-2, 100% fuel, 6x100kg bombs
- altitude 2000m
- IAS 330km/h
- bullseye placed at 0m elevation on the shore to simplify the calculations
- no wind on the maps
- coming in from the water

Calculations:
- got TAS from IAS and ground temperature as per your equation
- got the bombing angle using the calculated TAS and altitude

Results:
- good hits on the Crimea map (at least one bomb landed within the pattern)
- bombs fell short on Moscow winter map by at least 3 patterns

So some other variable comes to the play when calculating the bombing angle - maybe the air density/resistance...
