an alimeter is a weather instrument which measures the alitude of an object above a fixed level
An alimeter is an instrument used to measure altitude or elevation, often utilized in aviation and mountaineering. It typically works by measuring atmospheric pressure, which decreases with increasing altitude, allowing users to determine their height above sea level. The term can also refer to devices like altimeters used in aircraft to gauge their altitude during flight.
An altimeter is an instrument used to measure altitude, which is the height of an object above a reference point, typically sea level. It operates by measuring atmospheric pressure; as altitude increases, air pressure decreases. This information is crucial for pilots, hikers, and mountaineers to determine their elevation and ensure safety during navigation. In aviation, it helps maintain safe flight levels and avoid obstacles.
