Product Definition Definition of approved item name (AIN): "ALTIMETER,SERVO CONTROLLED,AUTOM"

A servo controlled instrument which measures altitude by dial indication transmitted by synchro from a remote source. The transmitted altitude may be pressure altitude as derived from an air data computer or other suitable transmitter. It employs a zero setting system to permit the altimeter to be set at zero altitude at an existing ground level. The item incorporates an automatic standby feature which will revert to direct static pressure actuation, indicated by a warning signal in the event of electrical malfunctions or at the pilot's option. The item is designed for use in aircraft where accuracy is required to meet altitude separation requirements. See also information positioning set.
