Here's a thought:
It's been about 5 and a half years since AF 447 went down.
Been about three years since the recovery of enough information to understand why.
What has changed?
a. In the industry?
b. In that company?
As I understand it, there was a review/renewal of how to proceed when all three air speed indicators go on holiday at once. (But then, the Pitch and Power chorus already had that answer before the aircraft itself was pulled out of the ocean).
I also understand that upset training has gotten more support.
Does anyone have a sense of the answers to a and b beyond those two points I have there?
