OK, I didn't realise this is discrimation according to [jet] aircraft type. That's well out of order.
My *guess* is that this is the often voiced "European regulator panic" over "thousands" of VLJs "clogging up" European airspace. So they decided to make it harder.
I spoke to somebody in the know this morning, and I gather these extra requirements will cost the pilot about £10k.
Of course if the plane is on the N-reg, he can fly worldwide, in all airspace, with a PPL/IR and a TR.... the Eurocrats really hate this.
