It may be out of character for me to say, but AirBus had 32 episodes of some hairy UAS that ended "well".
Neither Black, nor White, the upshot of 447 is that the Pilots may not have been ready, the a/c was, and neither could save the flight from destruction. Isolating any one 'format' is not helpful, there is a SYSTEMIC problem.
That said, 3hl and
Ed are also exactly correct.
airtren. I get your post perfectly. Isolation of events is proper, as is a "global View". Neither is helpful, if all things as a whole are not considered together.
"Somewhere between "Do Nothing" and ACM".... is the 'moving' target?
(relative to a/p loss/handover)........
