As a PPL, at present if I depart VFR from an airfield in class D airspace I always end up talking to xxx approach with a clearance to the zone boundary. Eventually, a few miles outside the zone, I ask to change to another frequency - this is approved with the request that I squawk 7000. At no time does there ever seem to be a 'contract' about the service after I leave the zone.
Now in the zone I am, presumably, receiving a control service - its never agreed if this this is radar control or simply control. As I cross the boundary I dont recollect being told that I'm now receiving FIS/RIS or RAS - I simply continue on track until either I or the controller decides enough is enough.
After Mar 12 how will this change? Am I responsible for knowing the moment I leave the zone and negotiating a BS/TS/DS - or is it down to the controller? By default what should he offer me?
