I cannot see EASA letting an 18 year old with 200 hrs total give that approval!
Well, yes (although an FAA CFII won't be 18 with 200hrs; that is a European speciality
) but that is just the reality of European politics.
One can debate the fundamentals but they will never change.
The US system, demonstrably "at least as good and mostly safer" will never be adopted here, partly for job protection reasons and partly
because it is American.
So, instead of flying 6 approaches within the last 6 months, I have to fly with a CRE/IRR and spend £150, once a year. (In fact I have to do both because I have both IRs to maintain). That's about the cheapest way to do it. Plus the cost of actually flying, so a renter will be paying lots more than that. For nothing.
