Yup, I've had the same sort of guff in the past. These idiots don't seem to realise that to be in EASA, a nation has to be either a member of EU or EEA (or be special case Switzerland) and I also wondered at the time how the "CAA could keep us aligned to EASA for two years". I'm guessing they hope to "align" during a transition period up to 31 December 2020 in the event a Withdrawal Agreement is reached. This WA looks highly unlikely as May is now in a post Salzburg strop and seems hell bent on a crash out. Fasten your seat belts!
