altimeter
Cockpit height reader
An altimeter is an instrument that measures altitude—height above a reference point, usually sea level or the ground.
Aircraft carry altimeters to show pilots how high they're flying.
Hikers and mountaineers use portable altimeters, often built into watches, to track elevation on climbs.
