An altimeter is a flight instrument that measures changes in atmospheric pressure to indicate the height of an aircraft or object above sea level or a specific reference point. These readings express the aircraft’s altitude above sea level in feet. Fundamentally operating on the principle of an aneroid barometer, the altimeter functions on the basis that altitude increases as static pressure decreases. Principle of Operation Altimeters used in aviation measure altitude based on the static air pr
