What makes you think that GPS could decrease the needed separation?


Because that is exactly what it is designed to do?

Ah, no. GPS was not designed for that nor can it provide that. Most in
trail separation today is based on wake turbulence. Even if you got rid
of wake turbulence you still can't get less than 2.5-3 miles for jets
because that's how long it takes to land, slow down and exit the runway.
If it's dry. And that spacing doesn't allow departures to get out
between the arrivals. So you go to five miles and if everything works
out perfect that's barely enough room to get the jet departures out.
The plain simple fact of the matter is the limiting factor is lack of
runways. No amount of technology can force more airplanes onto the
runways we have now.

Funny none of the airlines I know of are saying this. They are all
advocating just this upgrade and the FAA is going to have it build.
So just what do you know that those running the business don't?


Let's see. US airline management, which, collectively since day one
of air travel in the US, have managed to operate at a net loss, says GPS
will solve our problem. An air traffic controller tells you about spacing
requirements for both wake turbulence and operational requirements. And
you believe the airline management?

Airlines LIE. Pure and simple. Airlines LIE.

For example, I was once on a coast to coast flight when, just after
the cabin doors closed, but before push back, our captain gets on the horn
and tells us there will be a two hour delay due to weather. Well, as I
normally pull an FAA weather briefing before any flight I take, whether I'm
flying the airplane or just a passenger, I pulled out my briefing and could
not see any weather probelms anywhere on our route. The passenger in the
seat next to me noticed what I was reading and said that she worked at the
FAA ARTCC which covered our departure airport. She calls her coworkers at
center and they don't know of any weather delays. They then call the FAA
flow control center to see if there are any problems anywhere in the USA.
Nope, none whatsoever. Yet the airline is saying there is a weather
problem.

Airlines LIE.
