What are the situations in the air where you require full back stick or yoke? I can't visualize any other than EGPWS activation which is basically a lower level phenomenon unless you were flying over the Himalayas or Alps. Even at lower levels in a non protected aircraft it can cause structural damage. I am not sure this basic information is understood in that manner. A pilot doing that in any aircraft at cruising levels will stall the aircraft. In speed stable aircraft it may not auto trim but if the stick is held back disregarding the stall warning will the aircraft unstall itself without the yoke being released? In airbus FBW which is flight path stable once the stick is held out of neutral it is g demand reverting to AOA demand at lower end with the trim following it up unless the stick is neutralised. In both AF and QZ the pilot pulling and holding full back stick is extremely bizarre handling of the aircraft at those Flight levels. Any full application of flight control at cruise will end up in disaster. Full rudder will cause separation of tail, full bank can roll you on your back a 747 has done that.
