Abstract

An altimeter (24) of the aneroid type having a correctable digitizer 26 is shown. When the pilot sets the altimeter to the local barometric pressure, the correctable digitizer is also set to the local barometric pressure. An input device (58) connected between the barometric pressure correction control (66) and the digitizer (62) generates a barometric pressure correction signal (67) which is routed to digitizer (62). Barometric pressure correction signal (67) modifies the aircraft altitude output value of digitizer (62) to a corrected aircraft altitude output value (68) which is routed to one or more external navigation systems (70).
