rg, pine; the training required for AF447 after the malfunction was essentially to do nothing - recognising the situation as that requiring the second part of the checklist.
Before the event; avoid the conditions.
As with many notable accidents, attention is focussed on the outcome, and then why the crew were unable to prevent this.
An alternative view is that crew awareness and understanding was insufficient for the situation, or that with understanding the chosen action was incorrect.
Pilots require skills for situation awareness; the basics can be taught, but experience is required for more complex situations. This cannot be taught conventionally; it is best gained from corrected mistakes, outcomes not as expected, and saved to memory with understanding - facts, know what, - action, know when, know how, matching action with situation.
But in todays industry we are not allowed to make mistakes, no opportunity to learn.
