Worst instructor I've ever had: 737-300 TRI with 20000 hours of Phantom, F15, 727 and 737. Just yelled at you the whole time.
I don't care if you can do Sudoku while hovering in a Harrier. I don't care that if you look young enough to be my son or daughter. If I sit in the taxi thinking "that was a useful sim", you get my vote.
It's the same as the pointless debate about how many hours you should have to be the RHS of a jet. It's about STANDARDS. As long as you have a professional and experienced training management team, they will make sure that FO hiring, initial line checks, command upgrades and training promotions will be given to be people who make the grade. Will they get it right 100% of the time? Off course not. But the whole process has nothing to do with how many hours and how many types you have flown (within the minima of the regulators, obviously).
