Okay folks, since we're on this subject - can ANYONE tell me if Boeing has EVER flight tested the Backup Flight Controls in MANUAL mode? (I.E. Cable control on spoilers #4 & #11)
I am currently getting certified on the 777 and have heard from a few instructors, that boeing NEVER tested this in flight. (something about not being brave enough, blah blah, etc...)
If anyone can help with links or any other type of info to verify or debunk this claim would be GREATLY appreciated!
