Calibrated airspeed is defined as:

Calibrated airspeed is defined as indicated airspeed that has been corrected for instrument and position error. When an aircraft's airspeed indicator shows a certain reading, that value does not always reflect the true airspeed due to various factors, such as the location of the sensing source and instrument inaccuracies. By correcting indicated airspeed for these errors, you arrive at calibrated airspeed, which provides a more accurate measure of the aircraft's performance and behavior in the air. This is crucial for flight planning, safety, and performance calculations. Other definitions presented do not accurately describe calibrated airspeed as they refer to unrelated concepts or measurements, such as wind correction or altitude adjustment.
