Altimeter
An altimeter is a device used to measure altitude, or how high something is above a defined level, usually sea level. It works by sensing changes in air pressure, as air pressure decreases with increased elevation. Pilots use altimeters to determine their flight height, while hikers might use them to track their elevation in the mountains. There are two main types: barometric altimeters, which rely on air pressure, and GPS altimeters, which calculate altitude based on satellite signals. Accurate altitude measurement is crucial for safety in aviation and outdoor activities.

An altimeter is a device used to measure altitude, or how high something is above a certain level, usually sea level. It works by detecting changes in air pressure; as you ascend in altitude, air pressure decreases. In aviation, altimeters are crucial for pilots to maintain safe flight levels and avoid obstacles. There are two main types: barometric altimeters, which use atmospheric pressure, and GPS-based altimeters, which determine position through satellite signals. Understanding altitude is essential for navigation, safety, and ensuring proper distance from terrain.
