D
Costly
Ask EduPadi AI for a detailed answer
Correct Option: B
Pilots use an aneroid barometer to determine altitude because it's small and convenient. This makes it easy to install and read within an aircraft cockpit. The aneroid barometer measures air pressure, and air pressure decreases with increasing altitude. By knowing the relationship between air pressure and altitude, the pilot can determine the height above sea level.
