What term means the speed at which the aircraft is traveling through the air?

• A. Airspeed
• B. Ground Speed
• C. Velocity
• D. Thrust

Answer: (A)

Airspeed is the speed at which the aircraft is moving through the air. It measures how fast the airplane is traveling relative to the surrounding air mass, not relative to the ground. The airspeed indicator (pitot-static system) shows this speed, and it’s the value used for performance calculations like stall speed, takeoff, and landing speeds. Ground speed, in contrast, is the speed over the earth and changes with wind. Velocity includes both speed and direction, while thrust is the propulsion force, not a measure of how fast you’re moving through the air. Therefore, the correct term is airspeed.
