In the end we will end Uk with a mix of G-, OE- and HB- aircraft.
regulations concerning flying internaly within the EU. i.e. a Spain to Italy flight can (likely) not be flown by a G- aircraft as we will no longer be members of said union.
Lots of energy going into the AOC aspect, bnut I'm still curious about the pilots' licencing and TRE certification. I'm not sure, but Is HB part of EASA? Can a UK licenced EASA pilot fly an HB a/c. Can an HB TRE sign the LPC for a UK pilots & vice versa? Will any pilots need to OE licenced and/or will any TRE need to be OE authorised? I would not be surprised if there were some gremlins lurking in the dark corners, and that's from a glass always half full guy.
But I'm sure someone has the precise answer and we'll find it's all taken care of. But how, or is there no problem?
