You fall back on the same tire phrase, yet I do not believe you fully understand what you are saying.
What you mean to say, i believe, is Fly SELECTED Pitch and power...
And ROLL. You make it sound like 447 was smokin along in still air, no turbulence. They were not familiar with "selected value/Pitch". Have you flown in turbulence? Wind shear?
Select a Pitch, and it is instantly incorrect, modify your demand, and that too becomes wrong, now you are further off flight path.
The autopilot was actively manouvering the aircraft when it stopped making control inputs, and the a/c was off flight path. Had Bonin been instantly sceptical of speeds, he may have considered why the a/p quit on him. Would he have input rote values for PP? Why? The plane was moving, and we are taught to control in certain ways in turbulence. If your heavy was rolling and Pitching and you lost the auto, would you select a Pitch, a BANK, and HOLD it?
How? More importantly, why?
