Integration of Airborne Data Recorders and Ground-Based Computers for Engine Maintenance Purposes

摘要

The engine maintenance recorder portion of the data system consists of four major components: (1) Airborne magnetic data recorders, (2) Conventional long distance telephone data transmission links, (3) A centralized, ground-based, electronic computer complex, (4) Computer programming which permits automatic diagnosis of engine health, fault identification, and measurement of the urgency for corrective action. This integrated system is part of what is known as ASTROLOG. The other parts of the ASTROLOG include FAA crash recording capability on an extra channel of the existing voice recorder, and a continuously recording, magnetic tape, flight performance recorder. Highlights of the engine maintenance recorder portion of the ASTROLOG are discussed.
