and a simple fire test would prove integrity (wouldn't it?)
@ flightmech : that is pretty right.
What if it's a small leak and at idle thrust isn't enough to fed, or start, a fire? What if advancing the throttle puts enough fuel through to feed the fire and you think it's just a bleed leak???
@ misd agin : here you missed again. such a scenario will not happen due to reasons grounded wrote.
in general of course the abnormal checklist is the guideline what to to , it may be aircraft specific.
i always smile when emergencies and procedures are discussed . most the gents here are flying for virtual airlines without a doubt and of course rush in shutting down and train themselfes at engine out situations behind the monitor. the very few ones who are not just hope to never hear the fire bell. shutting down an engine which is not obviously at a real fire or catastrophic failure and produces thrust is a big decision.
especially when in bad weather/ IMC conditions, high gross weights, mountains in the area etc etc. your first thought is to see mother earth in one piece and not what the investigators will say. but thats only understandable for the gents who ever felt how the fear tastes sitting behind the steerings.
