Spitfire Mk IIa performance tests - Patch 1.07.18301

[Crumpp]

"Principles of Performance Measurement" but it may prove useful to you for gathering data for the Spitfire IIa once I have straightened out the script in my Performance.mis.

Yes it will be a great help in any future testing. It is silly to even discuss airplane performance without knowing the atmospheric conditions.

You can tell if the game is modeling denisty altitude by looking at the FTH. If the FTH matches standard day conditions, the atmospheric model is not correct.
