One's input to this thread needs to be moderated by what might actually happen in the very backward UK system.
But if one was starting with a clean sheet, one would bring in a lot more instrument training, computer (laptop) based flight planning (nobody going places seriously is writing out a plog by hand these days) and a lot of operational stuff so people can actually go somewhere.
In the USA, a new PPL can fly almost anywhere in the USA - because they have a simple unified system, with no Customs, no PPR, mostly H24 airports, one language, and one publication which has the airport details in a unified description. A European PPL needs to be more job-oriented if it is to serve the customer.
