I don’t think there’s any maybe there. It makes runways WAY more expensive to build, makes multiple runways largely impossible and gains... nothing.
It solves the angry runway problem.....
From the video.
The runway can handle three to four times the traffic of a normal runway.
You can alter the approach on extremely windy days.
You can also alter the approach to avoid only one approach area having to bear the brunt of the noise all the time.
I’m not sold on it, but some of the benefits seem reasoned.
“It makes runways WAY more expensive to build,”
Hold NASCAR events on the runway a few times a year to offset costs. :-0
