I´m curious how the whole thing is going to work. I´m convinced customers will complain about the strange inbound transitions at low altitudes instead of a pattern or two at higher levels. Also people on the ground will just love the low downwinds 20 miles away from the airfield.
I also see the main bottleneck at the departure end. There are so many dependencies between the different runways, inbound traffic and SIDs that it will be difficult to always comply to all restrictions.
I think theoretically the new runway will increase the capacity to more than 120 movements per hour, but the noise abatement regulations will make it hard to exceed 100/h.
