The intention behind this area of Part.ATS is that air traffic CONTROL will only exist within controlled airspace. Flight information services where traffic information is passed are ok, but anything where an ATS unit can instruct aircraft to fly headings will not be permitted outside CAS.
Edit......and I should add that includes ATC aerodrome control. So any ‘Tower’ed aerodrome would require CAS, whereas AFISOed aerodromes don’t.
