FYI, I am an MPL cadet & until this moment, with all of what was said...I still believe its the right choice, I am coming from a family of Aviators & ALL of them believe in the MPL. Most of my classmates are sons of pilots & the other guys who joined recently are coming from an Aviation background, not a single one of us has any doubts about the Success of the license.
There are some MPL graduates who are Flying, while the rest got interviewed by different Airlines...And I am proud to say most (if not All) of them got accepted & are going to start flying the jets soon.
BTW, Single Pilot Ops & Pilot incapacitation are included in our training (From MCC to Level D sim). Getting 50 hrs of VFR in a Cessna 172 & then 20hrs IFR on the Cessna again & then 120 Hrs of IFR on an A320 (Actual Flying time) sounds fair enough to deal with IFR/VFR problem. Having 110 hours of A320 Level D Sim, Would take you to the limits of all kinds of Ops (110 hrs...you'll learn the airplane even if you were observing!)
Lets wait & See, I am going to graduate with an MPL by the end of the year...
