From what I see there is no difference between this concept (apart from a million more pages of utterly useless paperwork) and how I was taught to fly over 65 years ago on Tiger Moths and later in the RAAF.
I guess that my Instructors deemed me competent when they let me fly solo back in the 60s.
I guess the reason they don't use C150s for training any more is that the aircraft cannot carry the student, Instructor, the CBT Syllabus, Training Matrix Achievement Record and the countless other bits of paper.
One question - Has this change to CBT made better pilots than the generation that were trained during WWII or the generation trained in the 60s and 70s?
