isnt the onset of compression dependent on IAS rather than TAS? ie pressure differentials again?


No. Compressability and stiff controls from from high speeds are are actually different phenomenon. As others have pointed, true compressability is a mach-related phenomenon. For instance, the 109 is *not* especially susceptible to compressability, it just gets stiff controls at high IAS. Anyway, as long as you keep most fighters under 500 on the TAS needle, they won't compress.

Oh!  I stand corrected.  Is this accurately represented in the game?  I haven't noticed TAS being the factor for compression, it always seemed like IAS.

HiTech has posted AH's mach conversion by altitude table in the past.  I guess another way I could have worded my reply was that yes compression speed changes with atmospheric pressure, but it doesn't coorelate with IAS.

I guessing somewhat faster than a laid swallow?  I know how I am.
