Creamy. Another good childish one
I have made it clear that the problem is when calls are made that could interfere with ATC control instructions.
I bet that at many times the Melbourne frequency is retransmitted on ATC frequencies that are also used to give control instructions.
In Queensland a number of years ago there was a serious breakdown of separation between a 747 and another airline aircraft . One of the explanations given by the contoller for the error was that his attention was taken away from the airline aircraft because of constant position reporting by a VFR aircraft.
Sounded a reasonable explanation to me - next time could be a real mid air.
I will say it again- go back to the old , proven but incredibly expensive duplicated ATC and FS system and VFR can give calls to abandon on the low level area frequencies- or move properly forward to the lower cost NAS system where all calls must be directed to ATC.
I love the concrete resistance to change. No wonder GA is in such a terrible situation.
