It's sort of key when taking that approach to actually succeed in not requiring the retraining.
Of course. That’s pretty common though, and you don’t hear about when that is successful. As an example, the 757 and 767 share a common type rating.
The safety value proposition of the max is kind of hard to sell after two planes crashed. It was already the most successful plane ever in terms of avoiding retraining right?
All that unlocked safety value didn't count for much.
