Electronic Management of Subsystems in the Supersonic Transport

The Douglas Electronic Management System (EMS) is presented in this paper. The requirements and the approach to an efficient electronic management of the subsystems of supersonic transport aircraft are reviewed. A method for assisting the crew by-monitoring, controlling, and recording functions automatically or as specified by the crew is discussed. Tasks considered fran pre-flight checkout to landing include: display of processed data; control of various subsystems; self-test features for pre-flight and in-flight checkout; and recording of flight performance, equipment status, and engineering data. It is shown that the potential of the EMS allows the introduction of a cable multiplexing system which permits the handling of more than one signal per wire.
