FADEC
I'm making the transition from the 7-3 to the Airbus. Our training manual is somewhat lacking in technical data, and I was wondering about the FADEC. On the overhead, maintenance panel there is a switch that allows maintenance personnel to power the FADEC while on the ground. Okay, understood. But when is the FADEC normally powered and ready to monitor and control the engine? Or, saying it another way, when does the pilot know that the FADEC for the first engine to be started is up and running?
