Title:Engine Electronics fire and overheat design guide
Issuing Committee:E-36 Electronic Engine Controls Committee
Scope: This document scope covers all of the considerations relevant to the design of a fire and overheat protection scheme for an aerospace electronic control unit.. The focus is the engine electronic controller (EEC) typically used on civil aircraft applications and mounted on engine, but aspects are also applicable to condition monitoring units and units mounted off-engine. Content includes aplicable regulations, assumptions, additional constraints, installation, compliance strategies and compliance testing.
