Writing to Euro MPs, with good well reasoned information, is the best way.
Fing is tho, from where might one obtain the "good well reasoned information"?
I'm quite happy to write to my Euro MP, or indeed simply have a chat with him next time I meet him, which I do from time to time, but what to say?
As far as I personally am concerned,
if there's some Euro-bollocks that means I'll have to pay £186 to convert one piece of paper to another in order to continue flying
or there's some Euro-bollocks that says I won't be able to continue using my IMCr on 172s rented from the local club
then I've got a problem, otherwise I haven't.
The CAA have told me absolutely nothing at all, other than "it's all up in the air, wait and see, but why not give us £186 in the meantime just to be on the safe side", and various pundits on various web sites have said all sorts of contradictory things, so without hiring my own lawyers and private detectives (which my wife won't accept as part of my flying budget) I haven't a clue what's actually going on, and thus haven't a clue what "good well reasoned information" to give to my Euro MP.
Erm ... ... ... ?
