Altimeter

An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth underwater. ==Pressure altimeter== Altitude can be determined based on the measurement of atmospheric pressure. The grea...

altimeter

A device that measures the height or altitude of an aircraft above sea level or, alternatively, the surface immediately below. Many aircraft altimeters are modified aneroid barometers and work on the principle that air pressure decreases with increased altitude, but these must be constantly recalibr...

altimeter

Instrument used in aircraft that measures altitude, or height above sea level. The common type is a form of aneroid barometer, which works by sensing the differences in air pressure at different altitudes. This must continually be recalibrated because of the change in air pressure with changing weather conditions. The radar altimeter measures the h...
