I dont think many of you guys sen the forest for the trees!
It is not whether an MPL holder is better than a CPL/IR holder or the route its taken to get there. Most of the sub 500hr guys and girls I have flown with are still in over their heads with having obtained the window seat. Its not till the gloss wears off that they become seasoned operators.
The point is simply a CPL/IR guy has other options and will easily transition to completing another rating, given the local requirements.
On the other hand, a MPL is simply a permit to operate a particular type of aircraft. Should a MPL holder even be offered a job to fly tourists or the like. They can not.
The "licence" for want of a better term is and industry restriction that has once again lowered the prospects for a candidate and further denied the narrow view in some parts of europe that a "light aircraft" is anything less than an ATR and hence is irrelevant.
Its a shame really to think this is happening and many forms of "Light aviation", pay better and have much better lifestyles that those of the "airline" world.
Which is something an MPL holder, will never realise or experience. Welcome to regulated slavery.
