Altimeter Working Principle. The pressure altimeter functions as an aneroid barometer, measuring the atmospheric pressure at the altimeter's location and displaying altitude in feet. It operates based on static pressure, which decreases with increasing altitude due to the lower density of air aloft compared to sea level.
