ATSOCAS disappears on 13 Nov to be replaced by UK FIS.
Alongside disappearance of (all??) Class F to be replaced, in places, by Class E.
Working Class G airspace is like swimming with sharks on occasions. Irrespective of the service the Duty of Care exists and it is up to Controllers to provide the best possible service they can. Likewise, it is up to pilots to ask for the appropriate service.
My understanding is that the next iteration of CAP 774 will state that controllers should respond to any given situation as they see fit, notwithstanding the service being provided i.e giving vectors under a Traffic Service.
