On independence - what they said was that initially nothing would change. NATs would still be contracted to continue the service they provide and admin would still be handled by the CAA down South.
I suspect that Scottish registrations would eventually appear, and airport designations would change from EG-
Most things are EASA controlled anyway so not a huge amount would be able to be changed anyway.
Bigger question would be about organisations which operate both sides of the border, like the LAA. Would it cease to exist north of the boarder? Would there need to be an LAA (Scotland) created, with higher fees for all of us up North?
Of course - we could stop all this speculation by putting an X in the correct box
But this has been discussed on here in other threads.
