Consider an MPL holder with minimum command time cross country in C152 or Tecnam or whatever, gets employed to drive in Back Seat, then in RH Seat of an airliner.
The MPL holder can drive the computer systems well enough in the sim provided there is not too much complexity, but never has to do a circling approach in marginal WX, deal with U/S systems or deal with any major decision issues in flight, as the CAPT shoulders all of the responsibility.
One day in the distant future he/she gets a command, and for the first time actually has no-one senior to fall back upon when the flight goes pear shaped.
Seabreeze,
What make the 250 hour MPL Cadet any better or worse than any other 250 h cadet.
As has been said, time and again, we have had about 50 years (fifty !!, five zero!!) years experience of 200h or so graduates going into the RHS of often large jet transports, and there is ABSOLUTELY NOTHING in the accident records to suggest that this is an unacceptable risk ---- a "safety" problem.
There is another thread on Flight Deck Forums about pilot minimum experience levels, worth a look.
Tootle pip!!
PS: I came up through the "traditional" GA steam, but as the years went on, I realized it was not the only way, or even the best way ---- if you are producing airline pilots.
