Good point Mr Brewster - At least NVFR, Tailwheel and Aeros. Although I'm sure 1000hrs of 2hr cross countries would see their fair share of 'issues' to deal with, certainly more that a mint CPL. Add the above ratings to it and you have
I'd apply the limit to the PPL and not the CPL as we're trying to get something different from both.
From the CPL you're getting professional training, attitude and oversight (excluding the walk up, "just sit the exams and do the flight test" low time variety (not you XXX, you likely count in the next bit
)).
With the high time PPL you are trying to get to the experience and knowledge that only a high time pilot can bring to the party.
Much thought beyond the walls of this forum needs to happen. Sadly there's probably not the right brains in the rooms where this will be decided to give us the best possible solution.
