Airborne altimeters are instruments used to measure altitude above a landing area or runway. They typically feature a radar or laser rangefinder to measure the distance between the vehicle and the ground and then calculate the altitude.

Airborne altimeters are considered essential pieces of navigation equipment for aircraft. They allow pilots to determine their altitude above the ground as well as their altitude above sea level. This information is critical for pilots to safely navigate and operate their aircraft.

Airborne altimeters are used in a variety of aircraft, including light sport aircraft, general aviation aircraft, and larger airliners. They are also commonly used in helicopters and unmanned aerial vehicles (UAVs).

Airborne altimeters work by measuring the pressure or density of the air. The higher the aircraft is, the lower the pressure or density will be. By calculating the pressure or density of the air, these instruments can determine the altitude of the aircraft.

In addition to altitude measurement, airborne altimeters can provide other useful data, such as airspeed and air temperature. Some models can also provide wind direction and speed, which can assist in navigation.

Airborne altimeters are critical for safe and efficient air travel. They help pilots maintain the correct altitude and provide important navigational data. As such, it is essential for pilots to have a working knowledge of how to use these instruments.
