Yes, and no. My neighbor flew the baby bus for ---Lines for many years. He was out of NORMAL LAW, exactly: not once. I am not sure what manual stick (NORMAL) accomplishes up high. The sim cannot duplicate what these three inherited. I could argue that it is a negative, perhaps imparting a false security when LAW degrades for real (which is hardly ever).

BEA say the a/c rolled right to 8 degrees, they do not mention trend, and therefore people assume it stopped at 8 degrees, right? The a/c started a rapid and cyclic ROLL that you have eloquently described, and hand flying in NORMAL LAW is nothing like it. It is NORMAL Law itself that wants mayonnaise, and AL that wants smoothe; so practicing mayo up high is exactly wrong, and could be the source of the entire problem? DIRECT ROLL with mayonnaise is poison.

There is one salient point that is my take away, that BEA mentions very directly.

Pilots of this aircraft MUST have an AoA reference, PERIOD.

cheers sailor.
