AIR6108 Engine Electronic Unit Fire and Overheat Design Guide

The design and testing of the engine electronic unit’s fire and overheat protection scheme is a critical task faced by the aerospace industry. It is fundamentally difficult to argue and demonstrate the safe operation of an engine electronic unit when subjected to fire, yet the design features introduced to address this issue must not jeopardize the safe operation of the engine that they control or monitor in normal operation. The aerospace industry has tried many varied approaches to reaching the right compromise in this difficult area and this guide highlights some of that experience that should aid the industry in general.
