FMS Ground Test Set
Couple of questions for the cognoscenti among us:
a. If an FMS ground test set (such as the FMZ-2000 - used to replicate flight on the ground in a static aircraft) was plugged into the FMS in the avionics bay, would it have precedence over cockpit inputs (whether or not they remained intact and plugged in)?
b. There'd be a headset jack plug in the avionics bay for AVbay to flight deck liaison comms I'd imagine?
