PSA CRJ-700 AA midair collision

very much doubt climbing to 1500’ would solve anything on 33 as that would just put them beak to beak on route 4 with next final traffic on 1 or to people beginning the 33 circle
 
Any situation that sets up something the controller has to watch is going to cause more workload. So even going high, it doesn't change the controllers workload and only marginally increases the safety of the situation. That is why we use visual separation because generally once the pilot accepts the visual separation and the other requirements are met, we can put that situation on the back burner. Not to say we stop watching it completely but it goes to the bottom of duty priorities.

LI don't know the airspace at all, but I imagine there is some sort of institutional reason for not going above with the helicopters, whether it be other traffic, or just operator preference, we don't have the whole picture here.
 
Push the helicopter route inland and east over I-295, require the circle to remain on western shore. Keep altitude for Helos over 295 low which would further deconflict.

While the visual separation and instruction to cross behind the RJ would’ve worked out also.

Hold to the north, maintain 1500 on the route, or fly the route. All can be done without visual separation. In the DCA environment, asking anybody to maintain visual separation at night should raise an eyebrow.

I haven’t done a deep dive into the report. I’m curious if there was a meaningful collection of data that looked at how often helicopter traffic flew the route with or without visual separation instruction. I don’t have a sense how much deconfliction was happening with relatively sparse helicopter traffic.
