I guess the primary goal is not noise abatement or "green" CDAs this time. But the big increase in capacity.
In the briefing we were given CDA is a possibility in the future with this concept, but not the goal this time.
They're still flowing through the peaks. I'm looking forward to seeing full capacity and how efficient the system really is.
I'm not a pilot, but I guess I'd rather fly 50nm in FL110 than 50nm at 5,0FT.
