Dick,
Oz, pull the other one, if the VFR remains east of the highway it will be up to 15 nm from the tower when abeam.
The controller would have to have good eyes!
And what happens if he can't sight the VFR?
Get the IFR to start orbiting?
That's why C requires radar in other astute aviation countries.
The VFR was not inbound- it was heading north.
And how, pray tell, do you expect IFR-RPT-me to do any better if the VFR was in E? Just say "stuff it, we're going down through your level. We'll pick you up sooner or later."? I would be causing chaos on the Centre freq as I organised my own separation until I picked him up visually (unlikely until I was on top of him). Maybe I would hold myself up and cost a hundred or kilos of CO2. I know. I'll change to VFR. That'll fix it.
Admit it, you don't know what goes on in the real AUS world. Your attempt to implant a totally different NAS into ours will end in tears, just like it has done in the past.
