Ah this is competency based training, or close to it. It has been tried several times in the last ten to fifteen years and often fails because the old crusty flight instructors (a) don't get it in the first place and (b) even if they do what they are told initially they revert to their old ways unless you constantly hammer them with instructor standardisation. This has a cost, and no-one pays for the benefit so too often it slips back into the old way of doing things. This is the core reason why competency based training as a concept is now being taught at ATPL level under the guise of KSA-100, eventually it will trickle through to the only sector yet to adopt competency based training. Yes, ab-initio flight instruction. The future is coming.
