ATCs can't have much to do if they can also do Flight Watch
Sorry, Dick, are you proposing that IFR and VFR in the same airspace be on different frequencies? IFR with ATC, and VFR with FlightWatch?
I've done a bit of flying in the States, one of my best mates is a corporate pilot in the States, he's got a firm hand in GA and still instructs. VFR's DONOT listen out on control frequencies unless they want a clearance into controlled airspace. They listen out on 121.5.
What makes you think that an aviation backwater like Australia & apathetic pilot community that has allowed a disastrous aviation 'reform' to takeover knows what's best in aviation? Australians are not experts in aviation.
