The question has to be asked.....is this in the name of Safety or jobs for the boys? Where is the evidence that people are falling out of the skies left, right and centre due to not flying with an examiner every 6 years?
I really think Europe should look at the USA and FAA - who after all invented flying. They have it right in my humble opinion. Firm but fair. The BFR satisfies everything that is needed, every 2 years. A rating is for life, not just for 1 year. Those that have lapsed (IR) can be renewed by instructor training.
Worse case scenario, I'd even give up flying group A (or whatever it is called) in Europe completely and just go to the USA 4-5 times per year and fly there at a quater the cost. There are only so many hoops I am prepared to jump through.....
