We need MPL so that the 250 hr. Comm/Multi/Inst pilot can go straight to a mentored position as a first or second officer and not have to waste their time and money beating around the traffic pattern as a CFI till 1500hrs.
I used to work at a major (non flying positions), and the topic of MPL came up frequently from leadership whom had never been privy with what initial pilot training entailed. After presenting many decks on what exactly MPL was, and what it omitted, no one was onboard with ever advocating or lobbying for a 'true MPL' in the states. An MPL only requires ~75 hours of actual flight time in Phases 1 and 2, with ~225 additional hours being taught in a full motion simulator or FTD. This of course severally constrains pilots from learning a methodical decision making process, and does not allow them to experience real world situations, where decisions have to be made.
That being said, I am a big fan of a 'hybrid model', where ratings are still earned in a (flying) aircraft, and chances to make (and learn) from mistakes is presented, That being said - having several hundred hours in (or watching) a multi-crew environment (even in an FTD) is still invaluable as I have seen first hand the struggle of 1,500+ hour pilots moving from a trainer to a jet transport...and firmly believe that there needs to be a more concrete 'apprenticeship' programed developed before pilots should be expected to thrive in the airline atmosphere. If you look at the jetBlue 'Gateway Select' program, and compare it to a EASA MPL, it is nearly identical, with the only difference being their students still have to earn ~1,500 hours of flight experience...other than that the 'phases' and 'modules' are nearly identical.
The notion that the regionals are that
apprenticeship is a flawed ideal, as passengers are absolutely not purchasing an apprentice flight crew member, nor are there any discounts or differentiators when flying on an outsourced E175 to IAH versus a mainline operated E190.
Although I have no personal investment or involvement in the Republic LIFT Academy, I hope that this program has the ability to create a true apprenticeship for the sake and sanctity of the pilot profession.
