If loss of two ADR creates Alternate, and BUSS takes it to DIRECT, should (can) BUSS be deselected? Or preferred?
During BUSS operation (3 ADR OFF) the flight continues in ALTERNATE (less Hi speed protection).
BUSS can be deselected by restoring 1 ADR, don't know if the Hi speed protection is also restored.
Odds? 10,000/1. Worse?
Cheers, they're on it....
