The same for visual separation, where only one or two aircraft in the area make misidentification of traffic an improbability. Unfortunately the reverse is true. The busier and more congested the airspace, the more likely these procedures are to be used. From a risk identification and management perspective, I just don't see how operating like this can ever have been deemed acceptable.
Again though, it's used because it's the only way to squeeze an extra 1% out of an over burdened system. And worse of all, everyone involved, from pilots to ATC, think they're the worlds best for making it "work".
I’m not in job of defending the US system, but there needs to be some perspective. The US airspace operates about 40%-50% of all global aviation. Only half of daily flights are air carrier. For lot of reasons outside this discussion, air carriers are the default transport, trains and buses are a tiny fraction of long distance transport. Apply EASA aviation standards and the US network would grind to halt or create huge gaps in service. We’ve gone 16 years without a fatal US carrier major accident, which isn’t different than the rest of the world, especially when the US has a 50% share. Our economy would suffer greatly and passengers revolt at what would required.
All that said, the plan for DCA, particularly the helicopter ops, were hazardous in the extreme. The Route 4/33 operations is just plain dangerous, nothing less. The politics of DCA are going to drive a band-aid fix is my prediction. Visual separation won’t go away. FAA will get crucified over manning. DCA may lose some significant service, if we closed 33 permanently. If I read the NOTAM correctly, closing 4 and 33, the pain will become known, interestingly, I read elsewhere that the helicopter altitudes were raised to 200’ in 2023 due to noise complaints.
