Have to say you are coming across as having a bit of a chip about people doing PPLs in the US. I realise you're a FI here and may be concerned about loss of customers, but my impression is only a small percentage go to the US.
I don't think you can blame the US schools for failing to explain that further training in home countries is a good idea, and is likely to be essential in most places for self fly hire. Isn't it up to the UK school/club to impose a reasonable reqiuirement for safety reasons?
Flying Lawyer's point was a fair one wasn't it? And he made it much more gently than many would have. It's not really hindsight is it? You're Maidenhead based so presumably your school must be somewhere near LHR zone - or even just up the road in it? If a new PPL who'd trained in for example Scotland turned up, wouldn't it normal practice to make sure he was famil with the zone before letting him loose. Or for a FI to check his planned route?
