Electronic Propulsion Control System/Aircraft Interface Control Documents AIR6181A

This SAE Aerospace Information Report (AIR) provides guidelines to document the functional and physical interface requirements for the electrical systems (including an Electronic Engine Control System (EECS) and its components) between a given propulsion system and the aircraft on which the system is installed.

The Interface Control Document (ICD) is considered to be a subset of the Engine Installation Manual, with interface considerations between the Airframer and Engine manufacturer. Although it can be developed concurrently with the Airframer and Engine manufacturer, its format and content result from an agreement between the Engine and Aircraft Type Certificate Holders, using the Certification Guidelines.

Within this document, the following definitions are adapted from the AC33.28-1 and CS-Definitions:

The term “EEC” is used to refer to the Electronic Engine Control unit. The term “aircraft” is used with the global meaning of aircraft or rotorcraft.

The scope includes commercial and general aviation aircraft powered by piston, turbofan, turboprop, and turboshaft engines equipped with electronic engine controls. It can also be applicable to an Auxiliary Power Unit (APU) equipped with an electronic control.
