What Does KCAS Stand For?

KCAS stands for Knots Calibrated Airspeed

KCAS, or Knots Calibrated Airspeed, is a critical aviation measurement that represents the aircraft's airspeed corrected for non-standard pressure and temperature variations. It is derived from the indicated airspeed by accounting for instrument and position errors, providing a more accurate depiction of the aircraft's true performance in flight. KCAS is essential for pilots to ensure safe and efficient operations, particularly during takeoff, landing, and maneuvering.
