Unstructured seems to be the RAA's buzzword. Bedford and others have used this term. They are portraying the 1500 hours as purposeless boring holes in the sky, but doesn't the ATP still have structured requirements? If the RAA says there needs to be structure, what structure are they providing to build the experience? If 1500 hours is too much, what is the proper amount? I have heard Bedford claim that since military pilots can be qualified in turbojets at 300 hours, why does the FAA require 1500 hours. Of course, we all know that the selection and training of military pilots is highly selective and structured--and full of expensive simulator time too.
So using these simple observations the RAA position can be torn apart.
What concerns me is what happens if the aircraft manufacturers get behind this rollback effort. They are designing and promoting airliners that can be flown by pilots with very low time--hence the MPL.
Recent crashes by AF and Asiana show what happens when pilots are not given a good foundation in airmanship. They can operate the plane, but not pilot it.
