If the Right FMC fails:
A. Autopilot Disengage if Autopilot A is in use.
B. Autopilot Disengage if Autopilot B is in use.
C. Autopilot Disengage if either Autopilot is in use.
D. Autopilot doesn't disengage regardless which is in use.
This is a question from my annual renewal. The Instructor seemed to think it is B, but I think the answer is D, however I can not find a reference to prove it.
Anyone know the answer with a reference to the 737 technical manual.
Cheers to all
