With 1/8 sm vis, I can’t imagine you meet the criteria. I would also assume controller applied visual separation would apply here as well? But maybe I’m only familiar with it because we don’t have a radar in the tower. Nonetheless, I’ve held departures with an arrival on a 10 mile final because I can’t even see the runway environment. Admittedly that would probably be different if I had a radar but I’m not trying to fuck around and find out.
I’d rather people think I’m a shitty controller for holding someone than the entire NAS know I’m a shitty controller by sending it. No need to be a hero and damn sure don’t need to prove anything.
