I simply don't understand the question. Under ICAO there is no mandatory radio requirement for VFR in E ,F or G.
It will work like the way it does in the USA. Canada and. Europe.
But safer because we have a mandatory transponder requirement for VFR in all E. And far lower traffic density.
Advocate " and radar like coverage down to the ground at Hobart". So why is AsA claiming it was never planned to work below 6000'? I know. They are not telling the truth.!
I hope I can get some support in getting that Tassie system to work as planned. Will make these places safer without doubt.
