It's easy to ask for FDs off and turn them off in normal sunny daily operations. But when the workload is significantly more than usual, I saw guys pressing the ILS p/b instead of the FDs p/b or only pressing one of them when I asked for Fds off. Or sometimes a simple task of challenge and response during landing checklist can be challenging and slower than normal.
So now imagine during a stall... xD.
I'm with Vilas and Cpt Pit Bull on that one. The waste of time for asking for something non standard in an upset situation that even a delay of a fraction of a second can be fatal is not a good idea. The priority is always to FLY first.
And 'FLY' means for the PM: ''He must assist the PF and must actively monitor flight parameters and call out any excessive deviation. The PM's role of actively monitoring is very important'
In a stall monitoring is much more important than playing with the FCU.
80% of the aircraft accidents are due to poor monitoring according to Air France.
