The reason everyone seems to be obsessed with mandatory radio and ADS-B above 5,000 feet is because that is where (in the old days) Flight Service Officers could provide a service to both IFR and VFR with their existing staffing levels.
... simple question Richard, do YOU want VFR involved below A050?
Of course, where the risk increased at lower levels at airline airports such as Taree, there was no requirement for the VFR aircraft to be in the system – therefore traffic was not given by Flight Service.
... errm are you referring to before or after your dismantling of the Flight Service system?
It was a claim made by politicians – and we always believe them, don’t we?
.... people with half a brain might ... and errm what would you (and your involvement in issues such as this one) classify yourself as?
.. this should be good viewing
