indicated airspeed
Definição1
The uncorrected reading of the air-speed indicator. It is calibrated to reflect standard atmospheric adiabatic compressible flow at sea level uncorrected for air-speed system errors. It is equal to 1/2 p V2, where p is density and V is true air speed.

Definição2
The reading of airspeed from a pressure instrument in the aircraft, corrected for instrument and parallax errors, but not for pressure errors.

Definição3
Shown on the dial of the instrument airspeed indicator on an aircraft. Indicated airspeed (IAS) is the airspeed indicator reading uncorrected for instrument, position, and other errors. Indicated airspeed means the speed of an aircraft as shown on its pitot static airspeed indicator calibrated to reflect standard atmosphere adiabatic compressible flow at sea level uncorrected for airspeed system errors. Calibrated airspeed (CAS) is IAS corrected for instrument errors, position error (due to incorrect pressure at the static port) and installation errors.
