What is a sentence using the word altimeter?

The pilot checked the altimeter to be sure the plane had reached the optimum altitude before the skydivers were allowed to jump. Most altimeters have to be set to local air pressure to correctly determine the plane's height above the ground.


How does altimeter measure help pilots?

An altimeter measures an aircraft's altitude by comparing the atmospheric pressure outside the aircraft with a pre-set standard atmospheric pressure. As the aircraft ascends, the outside air pressure decreases, and the altimeter reflects this change in altitude. Accurate altitude readings are crucial for pilots to maintain safe separation from terrain and other aircraft, navigate effectively, and comply with air traffic control instructions. Overall, the altimeter is essential for safe and efficient flight operations.


How did the altimeter come about?

The altimeter was developed as an instrument to measure altitude above a fixed level, typically sea level. It operates based on the principle that air pressure decreases with altitude, providing a way to estimate height. The altimeter has evolved over time from simple barometers to more accurate and reliable instruments used in aviation and outdoor activities.


Which instrument is used for measuring altitudes in aircraft?

An altimeter is the instrument that is used for measuring altitudes in aircraft. It indicates the height above a reference point, typically sea level, and provides crucial information for pilots to maintain safe flying altitudes.


What instrument do airplane pilots use to detremine altitude?
