Hi! I'm brand new to the AVSIM Community, and grateful that this exists! I have been using a Gippsland GA8 Airvan aircraft (by Brian Gladden downloaded from Fly Away Simulations who ported to FSX from FS9). It is a great model, but there is a specific failure to the generator / electrical system I would like to add (failure of the over-voltage relay that protects the avionics bus over 16vdc). Is it possible to add custom failures to the aircraft failures list for selection? I've dug as hard as I can in various .cfg files and FSX files, but I can't find anything that relates to the failures list. If it is possible to add custom failures, then I'll spend some time looking at the switch and guage interactions for the fault. Any help and pointers gratefully received. Thanks, Pete.
