This SAE Aerospace Information Report (AIR) provides technical information regarding Engine Control Systems Interdependencies strategies and/or functions. This concerns aircraft with multiple power sources: at least two engines, whatever the nature of the power source is (electrical motor or gas turbine engine).
Within this document the aircraft stands for fixed-wing aircraft as well as rotorcraft. The term EECS or FADEC is used for the engine electronic control system, whereas the term EEC is used for the electronic unit itself.
The scope includes civilian aircraft powered by turbofan, turboprop, turboshaft and electrical engines equipped with electronic engine controls. Military aircraft is taken into consideration, however restricted topics that change the operational behaviors are not discussed.
Rationale: In response to a request from the SAE EASG (Electrical Aircraft Steering Group), this document is intended to address topics around Engine Control Systems Interdependencies. This document is intended to cover existing topics/state-of-the-art in the industry in terms of Engine Control Systems Interdependencies, as well as to address new kinds of interdependencies linked to the growth/development of fully electric aircraft or more electric aircraft (MEA).
