Which term describes the method used to communicate airspeed in pilot/controller communications?

• A. Ground speed
• B. True airspeed
• C. Indicated airspeed
• D. Mach speed

Answer: (C)

The term that describes the method used to communicate airspeed in pilot/controller communications is indicated airspeed. Indicated airspeed is the speed shown on the aircraft's airspeed indicator and is essential for operations involving navigation and maneuvering. This form of airspeed is vital because it reflects the aircraft's performance characteristics in relation to the surrounding air, incorporating adjustments for altitude and temperature variations that could affect the air density. In air traffic control communications, indicated airspeed is often used to provide necessary information for maintaining safe distances between aircraft, complying with air traffic procedures, and ensuring that aircraft operate within their safe speed limits during various phases of flight. Other terms like ground speed, true airspeed, and Mach speed pertain to different measurements and contexts. Ground speed refers to the speed of the aircraft relative to the ground, which can be affected by wind. True airspeed adjusts indicated airspeed for altitude and temperature to reflect the actual speed of the aircraft through the air. Mach speed represents a dimensionless number that expresses the ratio of the speed of the aircraft to the speed of sound in the surrounding media, which is typically used in high-speed flight situations. Thus, indicated airspeed is the standardized figure used in pilot/controller exchanges because it directly corresponds to what
