Which term is not one of the three standard airspeed types?

Explanation:
Mach is not one of the three standard airspeed types. The three commonly used airspeed types are indicated airspeed (what the airspeed indicator shows), calibrated airspeed (IAS corrected for instrument and position errors), and true airspeed (CAS corrected for air density to reflect actual speed through the air). Mach number differs because it expresses speed as a ratio to the local speed of sound and becomes important at higher speeds where compressibility effects matter. So while Mach relates to speed, it isn’t categorized with IAS, CAS, and TAS as one of the standard airspeed types.
