The area immediately around Edinburgh is Class E, but the TMA above and around that is D, then there is A above and around that.
It's all a bit confusing and I can imagine if the ATCOs spend 99% of their time vectoring transport aircraft in controlled airspace they don't have to worry too much about the nature of the space.
But I still would have thought that they would be dealing with enough VFR traffic for this issue to come up.
Today I was vectored by Scottish through some Class A VFR. Of course that was fine, and Class A airspace is made of the same gasses as any other, the controller knew where I was and was, I imagine, creating IFR separation anyway, but it did again give the impression that airspace class is not at the forefront of their minds.
I am just seeking to understand. Prune Radar, this is your area; no comment?
