You may be aware of claims (on the French forum) that the particular configuration (weight + flight level + assumed full aft CG) was allegedly very hard or impossible to fly with A/P off in the simulator.
They must have forgotten how to fly. I find it unthinkable that a legal configuration (and one eminently expected) can be in any way be 'unflyable' in
any law state. How could the airplane be certified if that was the case?
