As a practicing aeronautical engineer I am debating with my Operations colleagues the correct procedure in response to an Engine Fire Warning if the warning goes away prior to shutting the engine down. My view would be that you shut down anyway and isolate fuel, hydraulics etc. My pilot friends say if the warning goes away at idle it was just a hot gas leak and they would continue with that engine at idle. Any views? Does it make a difference how many engines you have? Is there a normal practice in the civil field? My background is in the fast jet military field, but in this case we are talking about a medium size tactical reconnaisance aircraft. Also can anyone tell me about normal practice with respect to high pressure air pipes from a tail APU to engine starters. What precautions are taken on civil aircraft against hot gas leaks(220 degC,430degF)? Leak detection wire? Double walled pipes? Are assisted relights of engines allowed in flight or only windmill? Thanks for any info. Gerald Wilson.
