Out of interest what Structure do the Intergrated courses have in the their Hour building? Does an Instructor sit down, with each Pupil brief him on what he wants him to do for that flight. What he has to achieve and what is expected of him. Do they then, de brief them? ask them how the flight went etc. How do they know the student actually did what was asked of him as he wouldn't have been in the plane for the flight.
I personally think that there is a failing in the Hour building for the simple reason that there is no structure. It is the only part of becoming getting your Fatpl that is left to chance and the integraty of the student. There is nothing to say a student doesn't bounce around the circuit for 95 hours, you would hope he'll great at landing a C152 but other skills would be totally lacking. This would obviously be highlighted when he does his CPL and probably take him longer to complete.
In my mind the CAA should really have some say in what should/needs to be achieved, their only stipulation is a 300mile Xcountry flight and I can see why airlines take issue with this andtherefore prefer Intregrated students.
Having said all this, If the individual isn't prepared to take responsibilty for his/her training and development while doing their hour building then I don't think they are of a suitable mind set to progress to the CPL stage anyway.
If the MCL solves this, great..
