This SAE Aerospace Information Report (AIR) provides guidelines to document the functional and physical interface requirements for the electrical systems (including an EPCS and its components) between a given propulsion system and the aircraft on which the system is installed and the functionality pertinent to each interface. The scope includes civilian aircraft powered by turbofan, turboprop, and turboshaft engines equipped with electronic engine controls.
In response to a committee initiative, the revision of this document is intended to elaborate on the structure and content of an Interface Control Document for the Electronic Propulsion Control System, to be used by the airframe/engine manufacturers. This document is based on the previously released ARP4874. It has been revised to reflect input collected as part of the ‘5-Year Review’ process.
