"1.4.2 Aircraft within an aerodrome traffic zone are required to comply with instructions from the air traffic control unit. Flight in Class F and G airspace outside the zone is permitted without an air traffic control clearance. However, controllers may assume that pilots of aircraft flying in the vicinity of the aerodrome in RTF contact with the air traffic control unit are complying with instructions unless they state otherwise.
Controllers are to provide an air traffic control service accordingly."
Porco Rosso, two points on that quote. The pilot in Class G is under no legal obligation to make RTF contact with an adjacent ATC agency (this is what the original point was all about). If he does opt to make contact, it is up to him to request a service and he retains the option to refuse a service or instruction. No pilot with an ounce of common sense would refuse an ATC instruction if safety were the issue. Unfortunately, it appears that GA is increasingly disadvantaged by delays / holding / re-routing for purely commercial considerations of airlines.
ATC unit cannot impose a service outside controlled airspace and should not expect to do so. It is up to the pilot to request a service and for he and ATC to come to an agreement about the type of service provided.
Rustle,
Not every pilot gets a copy of that publication - we don't.
