I'm not sure that CAA ATSD proof-read the draft CAP774 properly...
I suspect that what CAA ATSD meant to say was ATSORA (....Regulated....), and not ATSOCA.....
I notice that some ATC Units outside CAS are providing only Basic Service within their ATZ and thus NOT passing the required ATZ traffic information.
Sure as hell scares me.
Infact they have done so already.....
So, Keep a sharp look out within ATZs, it is certainly possible that you have not been given the full picture....
Outrageous.......
