As soon as your in someone elses airspace you have UK ANO and the airspaces "owners" ANO to comply with. It not an automatic right that you can fly G reg anywhere you like with a FAA ticket just because the UK ANO says its OK. yes your 100% bullet proof in the UK FIR outside that you better do your home work.
The aircraft is a VLA here, but a microlight everywhere else in the EU, so if the FAA PPL is rejected, I will pull out my UK and French microlight licences. At least I will be able to claim that I acted in good faith.
You could always call Tom Hughston for advice about the legalities of an FAA licence in the UK and on G reg aircraft in general.
Thanks, but there is no question of the legality of my FAA licence in the UK. The problem is that outside the UK in a G reg it depends on the national authority, and although there may be no specific prohibition, there is unlikely to be an authorisation.
I am waiting until June (?) to exchange my NPPL SSEA for an LAPL.
