Whilst i'm personally not in favour of the MPL (for very different reasons) i really do not believe that operational safety will be comprimised by these pilots. The way it has been implemented so far does not mean zero flight time (not sure what casa's been proposing but in europe there has been some flying). Stirling of norway (yes they have gone under but that was for different reasons) was very complimentary of the abilities of their MPL students. They did have significantly more experience of multi crew operations than someone coming out of a normal method of training. I did a 'normal' CPL/IR and the difference between what i was trained for and what i'm now experiencing in actual commercial ops is like night and day.
