What is Calibrated Airspeed (CAS)?

Calibrated Airspeed (CAS) Explained

Calibrated Airspeed (CAS) is the indicated airspeed of an aircraft, corrected for instrument and position errors.

Calibrated airspeed is the speed at which an aircraft is moving through the air, corrected for position and instrument errors. It's based on the reading from the aircraft's pitot-static system.

• Importance in Flight Operations: CAS is important for accurate flight performance, particularly in terms of lift and control.
• Use in Different Flight Phases: It is used by pilots for adherence to speed regulations, safe operation during various phases of flight, and for navigation calculations.
• Relation to Other Speeds: CAS differs from true airspeed (TAS) and groundspeed, which account for air density and wind conditions, respectively.

Calibrated airspeed is a fundamental airspeed measurement in aviation, providing pilots with accurate speed information relative to the surrounding air.
