About that APU fire story:
the FE to pull the APU fire handle and see if the light goes out. He did, it did and we carried on
To the "older" guys (I don't consider myself old yet, although some disagree
):
You've had the APU fire warning while in cruise, then pulled the fire handle and all warnings went away. Why would you want to continue to a distant destination when there's suitable airport nearby at that point I wonder?
How do you know for sure that it was a false warning, or that the real fire is really out. Even if the extinguisher worked as designed, how do you assess the possible fire damage to the area? If you're on an airbus, with electrics controlling all your flight controls, how can you assess that all that wiring going to the tail is still intact? Sure there's a firewall of some kind ahead of the APU, but I wouln't want to bet my safety on it.
