Which term is defined as the indicated airspeed of an aircraft corrected for position and instrument error?

• A. Calibrated Airspeed
• B. Indicated Airspeed
• C. True Airspeed
• D. Ground Speed

Answer: (A)

Calibrated Airspeed is the indicated airspeed corrected for position and instrument errors. The airspeed indicator reads the raw dynamic pressure as indicated airspeed, but due to the sensor’s placement and instrument tolerances, those readings aren’t perfectly accurate. Applying the corrections for those errors yields calibrated airspeed, which is a more accurate measure of the aircraft’s speed through the air. Indicated airspeed is the uncorrected reading, true airspeed is CAS adjusted for altitude and temperature (air density), and ground speed is TAS adjusted for wind. So the term that matches the definition provided is calibrated airspeed.
