John, you seem to be under the impression that GPS is going to somehow
manage to change the physics of time and space. Yes, when airlines use GPS
they can fly direct from point A to point B but if A and B are crowded they
are still going to have to wait on the ground to take off and fly around in
circles waiting to land.

Where did I say this? I said that if spacing can be reduced due to
safer wake turbulence management then GPS can be used to safely close
those spaces and improve the capacity of the system. That's all.
Just where do you think I am confused. And, if I am wrong (or
confused)

a. why is the FAA going ahead with the building of the system?

b. why are the airlines backing that change?
