Calibrated airspeed is defined as what?

Explanation:
Calibrated airspeed is the airspeed read by the airspeed indicator after removing errors from the instrument and the installation. The pitot-static system and the way the sensors are mounted introduce small errors, and CAS corrects IAS for these so the speed through the air matches the actual aerodynamic speed. It’s different from indicated airspeed (uncorrected) and from true airspeed (corrected for altitude and temperature), and it’s not the same as groundspeed (which is relative to the ground).
