Airspeed (noun)

1. Airspeed is the speed of an aircraft relative to the air through which it is moving.
2. Airspeed is an important measure for pilots, as it affects the aircraft's performance and handling characteristics.

Origin:

The word "airspeed" is a compound of "air" and "speed".

Examples:

1. The airspeed was carefully monitored during the flight, as changes in airspeed could have a significant impact on the aircraft's performance.
2. The airspeed was indicated by a gauge in the cockpit, giving the pilot an accurate reading of the aircraft's speed.
3. The airspeed was one of the critical parameters that had to be managed during takeoff and landing, requiring precise control by the pilot.
4. The airspeed was influenced by a variety of factors, including the aircraft's altitude, weight, and angle of attack.
5. The airspeed was a key factor in determining the aircraft's fuel consumption, with higher airspeeds requiring more fuel to maintain.
