A Correct answer
Explanation

True Airspeed (TAS) is the calibrated airspeed corrected for pressure altitude and temperature variations. While Calibrated Airspeed (CAS) accounts for instrument and position errors, TAS represents the actual speed of the aircraft through the air mass. This correction is essential because air density decreases with altitude, making TAS higher than Indicated Airspeed at altitude.
