Dick,
........A VFR aircraft calls up northbound when at 9500' about 30miles SE of Broome. How does ATC separate this aircraft from an inbound IFR comming from the west and descending from 14500' ? Must be really easy!
Please tell me that your are aware that we have been doing "procedural " Class C in Australia .... since ... since, before you put together your first transistor.
Basically, aircraft (both IFR & VFR) provide position reports. From that information, the Controller calculates potential conflicts and works on a plan to ensure the conflicts are removed or managed.
I can see a few quick ways to keep your examples apart:
- Track the VFR over water, the IFR over land
- Assign levels that keep them apart
A good current Controller would have another half dozen solutions up his sleeve. That scenario is not really a biggie.... as long as you know about both of them.
So how does a controller know if a vfr aircraft position is accurate in procedural class C when out of site?
It's a pilot responsibility to provide accurate position reports.
If he doesn't .... well, he risks the life of himself and others.
What if forgets to put his gear down?
What if he has too much power on?
What if he's drunk?
What if his license is out of date?
