A. Calibrated Airspeed means according to aircraft position, after correction instrument error, the aircraft display speed. Calibrated airspeed can be achieved when aircraft in flight in sea level standard atmosphere.

B. Calibrated Airspeed means the indicated speed of an aircraft, corrected for position and instrument error. Calibrated airspeed is equal to true airspeed in standard atmosphere at sea level.

C. Calibrated Airspeed is the speed of the aircraft shown on the instrument after error correction. The calibrated airspeed is the flight altitude and speed of a real aircraft under normal atmospheric pressure.
