If they vote NO then nothing changes, if the vote YES then thats their problem to sort, but in the event of a YES vote they will in time become an independent country and will have to establish the bodies to which you refer, some they may be able to outsource to rUK as customer and pay for the services they receive. This will apply to lots of agencies outside aviation, but it will be very much a one way flow from rUK to Scotland, the fact that the rUK will still be a 55m+ population and Scotland a 5.3m pop; will see to that.
My gut feeling is that Alex Salmond suffered premature popularity last weekend and the tide is now running against him, the big money boys have indicated they'll move South will unsettle voters whether they hate banks or not
