air speed indicator




airspeed indicator
An instrument that measures the speed of an aircraft relative to the air through which it passes. An air speed indicator measures the difference in pressures of air rushing through a pitot tube (generally mounted on the wing) and static air from a vent on the fuselage; air-speed is usually indicated in miles per hour or knots.
