So what?

You said GPS was designed to reduce airline delays. It wasn't designed
for anything of the sort. Nor can it do that.

I never said anything of the sort. GPS was designed for military
purposes and is being applied to ATC. That's what I said, along with
saying that the FAA and the airlines think that it MAY reduce delays
by up to 25%. Or put up your proof, if you have any, that it cannot
and won't.






You can't change basic physics. GPS can

generate some minor efficiencies in getting aircraft to the start of the
arrival which is 150 nm from the airport. Then everybody gets lined up
and fed to the airport. GPS is of little value from that point on in
reducing spacing. How are you going to overcome the basic fact that
2.5-3 miles is the minimum useable spacing, assuming no departures?


Uh, when someone else pointed out that it is currently 5-6miles you
don't call that increased efficiency? Where did you study math?

That additional distance is for wake turbulence and has been pointed out
to you before. Where's the benefit of GPS?

Uhh, if the minimum spacing now is 5-6 miles and it can be reduced to
2.5 miles that increases capacity and reduces delays.
