KIAS (Knots Indicated Airspeed)
KIAS, which stands for Knots Indicated Airspeed, is a measurement of an aircraft’s speed in knots that is read directly from the airspeed indicator. This measurement represents the speed of the aircraft relative to the air surrounding it, measured by the pitot tube on the aircraft’s exterior.
KIAS takes into account any errors introduced by the airspeed indicator and the pitot-static system, and is used by pilots for a variety of purposes, including air traffic control communication, flight planning, and aircraft performance calculations. It is also a critical factor in ensuring safe and efficient flight operations.
Pilots must be familiar with KIAS and be able to interpret it accurately. Incorrect interpretation of KIAS can lead to errors in airspeed, altitude, and other critical flight metrics. As such, pilots must be proficient in calculating KIAS for takeoff, climb, cruise, and descent phases of flight, and be able to adjust their flying accordingly to maintain a safe and efficient operation.
