MaxFacts: ATC, Out w/the Old; Whats new, “ADS-B”

FMaxSez: US, FAA-ATC; Out with the old In with the new! We all know Radio Beacons(VOR etal.) are History, GPS is the future. Next to Go; Radar, What’s next; Automatic Dependent Surveillance – Broadcast” (ADS–B) generally replaces ATC Radar/Radio NavAids, required by 2020.

What’s ADS-B ; The FAA is transitioning away from radar and towards ADS-B technology? ADS-B is an environmentally friendly technology that enhances safety and efficiency, and directly benefits pilots, controllers, airports, airlines, and the public. It forms the foundation for NextGen by moving from ground radar and navigational aids to precise tracking using satellite signals.
With ADS-B, pilots for the first time see what controllers see: displays showing other aircraft in the sky. Cockpit displays also pinpoint hazardous weather and terrain, and give pilots important flight information, such as temporary flight restrictions.
ADS-B reduces the risk of runway incursions with cockpit and controller displays that show the location of aircraft and equipped ground vehicles on airport surfaces – even at night or during heavy rainfall. ADS-B applications being developed now will give pilots indications or alerts of potential collisions.
ADS-B also provides greater coverage since ground stations are so much easier to place than radar. Remote areas without radar coverage, like the Gulf of Mexico and parts of Alaska, now have surveillance with ADS-B.
Relying on satellites instead of ground navigational aids also means aircraft will be able to fly more directly from Point A to B, saving time and money, and reducing fuel burn and emissions. The improved accuracy, integrity and reliability of satellite signals over radar means controllers eventually will be able to safely reduce the minimum separation distance between aircraft and increase capacity in the nation’s skies.

Nice to hear, thanks for the explanation @Maxmustang :)
