No, that's not correct and if you read the latest notice it states more than UK operators. It's immaterial to the many who have dealt directly with the Euro MEP's and Parliament leading the policy and derogation. They have written what I posted from my former colleague previously and signed it, and further to this it seems that the UK CAA are misinterpreting what has been written by the Euro MEP's. In no way does part NCC dictate any requirement for a UK validation, it isn't required. The unrestricted airspace and licence derogation has been confirmed by the European Authorities who apparently have full legal jurisdiction over this matter.
Mattman, if you want a copy of the MEP's email confirming this then pm me and I'll forward on your email address to my contact. And yes you are absolutely correct in your decision to continue as are the huge amount of pilots in the same position that have been in contact. I wish you all the best
