A380 engine fire trigger (Mod)

1st Official Post

    Hi everyone, I've been flying the A380 for a while now, and I've noticed that some buttons on the plane don't have any functions, but they are interactive. So I've given them some functions, like an engine fire. Later, I want to try things like landing gear jamming or avionics failure. Anyway, it's quite interesting.

    Additionally, I worked on a scenario where the engine completely fails after fire suppression measures are taken (even returning the EngineXFireButton to its original position doesn't work). In this case, the engine cannot provide thrust and cannot be restarted. However, I noticed that in real-world Airbus aircraft, after engine fire suppression, the engine information on the ECAM either changes to an amber "XX" and an amber arc. I've seen this symbol before starting the engine on the ground, but I never knew what it was called. If I knew, I could implement this functionality.

    The XXes appear when the engine display does not receive data from the FADEC. The FADEC is powered by the aircraft electrical system (when the engine is running or for 5 minutes when an engine start is expected or if FADEC man power is selected in the overhead) and by the engine's own permanent magnet generator as long as the engine is spinning. So if the engine has suffered some damage and stopped spinning then the FADEC's backup power is not available anymore. If the electrical power is also cut (might occur when the fire handle is pulled, I have to check that...) then the FADEC has no power and no data is transmitted to the engine display.

    In Aerofly we simulate the FADEC power as well, you would just have to make sure the FADEC of the affected engine is "switched off" then XX-es should appear.
