Did you ever read the UTTAS LOADS report? A quick stop with a tail wind, at low level at night over water, the issues are not dependent on whether you have franks rotor head or not, nor if you have a SAS system capable of entry into a hover. A level 180 with a confined radius at low level at night is also hardly a great option, one that puts the helo belly up to the traffic to remain over water, or doing a break into the traffic which is towards obstacles. I do not see that this flight path has been safe at any time, irrespective of how lucky the operators have been. If this is the de-confliction plan they need a new plan.
As an aside, the RHC is quite maneuverable, our low level / ag ratings using it require competency in torque turns, pedal turns which are entertaining but hardly beneficial to a UH-60 crew doing 115KGS towards a jet doing 130 KTS GS.
Fully agreed on most of your post. But don't tell me a heli cannot be given a "hold at" , "hold short of" or "hold abeam" instruction, I've got it many times. That does not necessarily require a quick stop. And this before this ridiculous dive to a 200 feet low pass to underfly an active approach barely a 100 feet above. I wonder who invented this procedure and allowed it to be used concurrently with aircraft on finals. If anything is asking for troubles, this is it.
