How does visual separation work when you are working remotely?
I am thinking about VFR helicopter crossings, also CAT A police helicopters that are frequently crossed ahead of IFR inbounds using the mark one eye ball.
Plus all,the other stuff which is done to keep,the movement rate high, wheels up departures, using the combination of the speed group table, SID routing and visual separation.
It's called a VCR for a reason.
