How do aircraft altimeters work

WebJan 10, 2024 · Altimeters: How they Work While used to measure height, Altimeters are actually sophisticated and calibrated barometers that are actually designed to measure air pressure. We calibrate an altimeter by telling it the air pressure at a given level, usually the surface or sea level. The inner workings of an altimeter are quite simple. WebOct 17, 2024 · Since the purpose of an altimeter is to use relative air pressure as a means of approximating the aircraft’s altitude, the altimeter must be built to read that pressure. An altimeter consists of a vertical stack of aneroid wafers sealed in a housing. A tube extends from inside the altimeter casing out to the static port of the airplane.

WebDescription Early radio altimeters determined altitude by measuring the time between transmission of a radio signal from the aircraft and reception of the reflected signal. … WebMay 18, 2015 · Altimeters are connected to a static pressure port, a little vent that's outside the aircraft. This senses the pressure in the outside air. For the altimeter to update with the correct altitude, it senses differences and changes in air pressure. As an aircraft climbs, the pressure decreases, and the altimeter registers an increase in altitude.
