Radar Services
About 2 years ago I was vectoring a Canadian registered minibus for an ILS approach under the callsign "Kestrel" with a Canadian crew. When I asked if they could accept a Radar Advisory Service outside controlled airspace the pilot asked "what is a radar advisory service". This also reiterates that in some foreign countries RAS and RIS are not provided and thus foreign pilots do not understand the implications of such services. Even though some airports need to provide radar services outside CAS, if you can keep them within CAS then do so.
