absolute altimeter

[′ab·sə‚lüt al′tim·ə·dər] (engineering) An instrument which employs radio, sonic, or capacitive technology to produce on its indicator the measurement of distance from the aircraft to the terrain below. Also known as terrain-clearance indicator.

absolute altimeter

An instrument intended to give acceptably accurate, direct indications of absolute altitude (i.e., the vertical distance of the aircraft from the surface of the earth). A radio or a radar altimeter indicates absolute altitude roughly because of its inherent errors. Theoretically, a laser altimeter should indicate correct absolute altitude and can therefore be called an absolute altimeter.
