An instrument which determines the altitude of an object with respect to a fixed level. There are two general types of altimeters: (a) the pressure altimeter, which gives an approximate measure of altitude from a pressure measurement and an assumed standard temperature distribution; and (b) the radio altimeter, which deduces altitude by electronic [..]

An Altimeter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth underwater. Altitude can be determined based on the measurement of atmospheric pressure. The greater the altitude the lower the pressure. When [..]
