Calibrated airspeed (CAS) is the IAS corrected for instrument and position error . An aircraft's indicated airspeed in knots is typically abbreviated KIAS for  Knots -Indicated Air Speed (vs. KCAS for calibrated airspeed and KTAS for true airspeed ). The IAS is an imp Express yourself. Organize your knowledge. Expand your mind. Discover the world.
Furthermore, the IAS is specified in some regulations, and by air traffic control when directing pilots, since the airspeed indicator displays that speed (by definition) and it is the pilot's primary airspeed reference when operating below transonic or supersonic speeds.
