SAE AIR5924B PDF
This SAE Aerospace Information Report (AIR) provides methodologies and approaches that have been used to install and integrate full-authority-digital-engine-control (FADEC) systems on transport category aircraft. Although most of the information provided is based on turbofan/turboprop engines installed on large commercial transports, many of the issues raised are equally applicable to corporate, general aviation, regional, and commuter aircraft, and to military installations, particularly when commercial aircraft are employed by military users. The word “engine” is used to designate the aircraft propulsion system. The engine station designations used in this report are shown in Figures 1 to 3.
Most of the material concerns an electronic engine control (EEC) with its associated software and its functional integration with the aircraft. However, the report also addresses the physical environment associated with the EEC and its associated wiring and sensors.
Since most current transport category engines use dual-channel FADEC systems, this is the configuration addressed by this report. A typical FADEC system configuration is shown in Figure 4.
