Genghis the Engineer:
Basic CPL for instructors,
MPL for airline pilots?
I might agree if those were the only two things that people go and do, and nobody wants to do both.
My point however was about using those two baselines to restructure the CPL into something more appropriate to both (as I said, downgrade the nav requirement from "excellent" to "good" and expand the comms and emergencies components; expansion of navaid use is also a valid debating point).
