For WWII planes outside of compressibility, there are generally these three airspeeds that matter.
IAS = indicated airspeed = what is read on the airspeed indicator, which is using a pitot tube to estimate airspeed.
CAS = calibrated airspeed = the airspeed after IAS is corrected for calibration of the airspeed indicator/pilot tube. CAS is usually close to IAS, and I think they might be the same in AH, i.e., the airspeed indicators are modeled to be already calibrated.
TAS = true airspeed = the true speed of the airplane through the air = sqrt(rho0 / rho) * CAS, where rho0 is air density at sea level, and rho is the air density at the altitude you are flying. At high altitudes, TAS is much larger than IAS.
When it comes to "questions" on the "Aces High Forums", I've always have looked at the question as pertaining to Aces High (the game itself).... I guess this is the one "sub-forum" where it can pertain to both the Aces High game and to "Real Life"
CAS = Calibrated Air Speed (CAS = corrected air speed)
Would not both be correct for CAS?

That handy little converter tool you haappened to have used in your post, didn't happen to be an "asa E6-B Flight Computer" sliderule, would it? just curious....

thank you HiTech, for help correcting me on my "TAS<-----corrected where I had originally typed it, then you gave the proper TAS = CAS....

Instead of using these different copys/versions of these asa E6-B calculating/slide rules.... I have a pretty neat one that is computer-based and is very informative....dew point, humidity, air density, wind direction. HDG, TAS, IAS, cross wind angle, etc......
