Remembering the relationship between the various speeds and understanding the conversion from one to another can be facilitated. Mathilde Carlier , Jun 29, 2023. Your KIAS will be 80 knots, because your airspeed indicator is just a dumb gauge, but your KTAS is actually a little higher because you're going a little faster to keep that same pressure on the pitot tube in thinner air. Part of the speed increase was from the more powerful engine; the rest came from improved wheel-fairing aerodynamics. It is the True Airspeed (TAS) adjusted for wind. The IAS is an important value for the pilot because it is the indicated speeds which are specified in the aircraft flight manual for such important performance values as the stall. 87 deg C.
