(1) If we are talking about setting up a slick training/hire operation:
Easy: find a suitable airfield, with a reasonably affluent catchment area, from which you can evict the existing school/club(s) and get somebody to do it properly. I can think of a number of locations but the "eviction" bit is impossible - one would have to wait for the existing ops to go bust which is likely to take a few years.
So, nothing is going to change.
The CAA will continue to discourage GPS use and mandate the ancient WW1 syllabus with the slide rule (which makes 95% of potential customers living in the 21st century take the micky and walk back out).
Even with a brand new slick operation it will be hard to avoid employing the same "60hrs in a C150 is perfectly OK, young chappy" types to run the show.
The trouble is that most punters already in the business are so skint that they will rent a piece of junk for £80/hr in preference to something better for £90/hr.
Also (in the face of competition) the junk operator can just drop his rates below the competition for months or years (exhausting his engine funds but that won't be a problem for a good while) making it awfully hard for somebody to compete.
There are lots of little things we have gone over and those could be done. But no matter how one looks at it, they are conditional on finding people who can actually afford this leisure activity.
(2) If we are talking about some PPLs getting their hands on decent planes for going places:
I think most people agree that self fly hire is the quickest way to oblivion, so shared ownership has to be THE avenue to explore.
It isn't hard for a bunch of keen PPLs to form a group around a decent plane, and even perhaps rent it out (to very carefully picked people) on top of that. One can get something pretty good for say £80k, and with 10 members that's "just" £8k each. That's no more than the average total spend on a PPL, and well within the means of anyone who has enough disposable income to maintain reasonable currency.
