Even more crass, latest GPS approaches published ,still require an ancient NDB in the procedure!
How quaint. That is so last century. In New Zealand we have GPS approaches at airfields where there are no ground based aids.
Approaches outside CAS are permitted but require ATC not just A/G or FISO. That said, they tolerate a single controller handling approach and tower, and quite a few places do this routinely.
Is that all approaches or just GPS approaches.
About 60% of the instrument approaches here are located outside Controlled Airspace with no ATC control what so ever.
