A Satellite System That Could End Circling Above the Airport
SEATTLE — Capt. Mike Adams demonstrated what the future will look like at the nation’s airports as he pulled back on the throttles of his Boeing 737 flight simulator, setting the engines on idle to glide smoothly from his cruising altitude all the way down to the runway. (www.nytimes.com) עוד...

The procedures will reduce approach time but if we don't add more landing space and runways I can't see it making much of a difference. All this assumes a clear path from descent to deck. Not going to happen unless we get more concrete and the FAA gets out of the stone age. What about weather how will that play into this matrix?
When the NextGen comes into full strength, not only the approach is being shortened but it also allows RNAV in the enroute environment. Old jetways based on VOR will be replaced with the RNAV route that doesn't require any VOR definition. This will increase airspace capacity, and also allow more direct routing (hence reduction in time too). Another side to it is the ADSB tracking rather than the old world war II surveillance radar. I think this allows reduced separation. "Target resolution" would be a thing of the past, may be?
and for aboutt $100 in parts I can ruin your whole day. No GPS, NO ADS-B and nor old world war 3 radar to keeps the system going. sound like the world I want to flyin, ADS-B will add advantages but has you GPS ever had you try to turn on a one way street, the wrong way?
I have always thought that a straight line approach from departure to detination would be the most economical and fastest way to operate an airplane. Of course, there a lot of other things which must be resolved such as more and longer runways and faster taxiways. When everything gets stacked up on the ground or in the air someone is going to wait!
I am a retired Pilot (35yrs), I sure wish they had started something like this years ago. I remember leaving CRUISE at 40%, all the way to the threshold. Before all these MANDATED ARRIVALS were put into effect. I just want to approach the field, not sight see the entire area! At 630 gph it is easy to see the cost effect if we all used 10-15 minutes less fuel on every leg.
If going into a busy airport I'm afraid Capt. Mike Adams will find that the kind of scenario vaguely described for a straight in approach flown in the simulator will only work in the simulator . Direct routes from the departure gate to the arrival gate with deviations for weather are already being used. Beyond the direct gate to gate routing just how does GPS/NexGen or any other new technology make this happen? Now if pilots want their aircraft controlled from a FAA computer program, controlling altitude and speed, then that might make a straight in approach happen. I do not want to be a passenger on those aircraft and I don't think a pilot would want to loose that control? Remember the great FAA microwave landing system where pilots would sequence themselves on a straight-in or curved approach? That worked out great didn't it? When have you ever heard airline 'A' telling airline 'B' "no, please you go first"!
