Results for tag: "Variometer"

A variometer is an avionics instrument used to measure the rate of climb or descent of an aircraft. It is typically used in conjunction with an altimeter to provide the pilot with an indication of the aircraft's vertical speed. Variometers are typically found in light aircraft, gliders, and helicopters. They are also used in some military aircraft. Variometers measure the rate of change in altitude by measuring the pressure differential between two points. This pressure differential is then converted into a rate of climb or descent. Variometers are typically calibrated in feet per minute (fpm) or meters per second (m/s). Variometers are typically powered by the aircraft's electrical system and are connected to the aircraft's altimeter. They are usually mounted in the cockpit and are typically equipped with an audible alarm to alert the pilot when the aircraft is climbing or descending at a rate that is outside of the normal range. The variometer market is an important part of the avionics industry. Variometers are used in a wide variety of aircraft, from light aircraft to military aircraft, and are essential for safe and efficient flight. Some companies in the variometer market include Honeywell, Garmin, BendixKing, and Avidyne. Show Less Read more
