I just started to try to use the Textron G58 aircraft. I cannot turn on the Avionics. When I try to flip the switch to ON, the MFD flickers briefly, but the switch won’t stay on. I tried starting the aircraft in cold and dark mode using CTRL ENTER: The Avionics switch briefly goes to the ON position, but then back off and the MFD is dark.
With SPAD, I can see that the variable AVIONICS MASTER SWITCH goes from 0 to 1 and then back to 0, when I attempt to turn the switch on in the cockpit. I can also see that the event ELECTRICAL_CIRCUIT_TOGGLE is fired once every time I try to turn the switch on. I think that’s from the aircraft itself in response to trying to turn the switch on. It doesn’t explain why it toggles twice.
I found one keyboard mapping to “TOGGLE AVIONICS MASTER”, namely the PAGEUP key. I disabled that mapping and it made no difference. I didn’t expect that it would.
However, I just found the culprit. There were two keys on my Bravo Throttle Quadrant mapped to AVIONICS MASTER1 ON and OFF. I disabled those mappings, and now it works! I don’t know why that only seems to affect this aircraft. I never use those buttons on the Throttle Quadrant.
