Pressure Altimeter

A pressure altimeter is a type of flight instrument that measures the altitude of an aircraft based on atmospheric pressure. It is commonly used in aviation to provide pilots with accurate altitude information during flight.

Pressure altimeters work by comparing the atmospheric pressure at the aircraft's current location to a standard pressure reference. As the aircraft climbs or descends, the atmospheric pressure changes, and the altimeter adjusts accordingly to display the correct altitude.

These instruments are typically found in the supply class Flight Instruments, which includes various instruments used for navigation, control, and monitoring during flight. They are part of the supply group Instruments And Laboratory Equipment, which encompasses a wide range of instruments and equipment used in scientific research, testing, and measurement.

Pressure altimeters are crucial for maintaining safe and accurate altitude control during flight, as they provide pilots with essential information for navigation, airspace compliance, and collision avoidance.
