Let me describe a sitiuation, see what you think. The zig zag of the Pitch trace is straightforward.
The trace of ROLL is interesting. In DIRECT, 447's Roll is difficult to define.
Admittedly back and forth, and within reasonably close tolerances in both directions, the argument can be made that this ROLLING saved the a/c from a spin. Let's assume that is the result, since each excursion seems to have been met with a force sufficient not only to arrest the Roll, but to command a reversal. Perhaps divine intervention, no matter!
Who would lay claim to such a result? The Designers? Make her titchy so that Roll can be managed quickly? Not likely.
Or is it? She Stalled, and crashed. But she did not SPIN.
Theoretical, but discuss?
