Occasionally, GPS satellites are spread across the sky in configurations that prevent a receiver from calculating a good position fix. When that happens, the unit’s receiver autonomous integrity monitor (RAIM) will generate an alert to the pilot to use an alternative navigation source.
Automatic dependent surveillance-broadcast
While most ADS-B installations will be in aircraft, system proponents see the technology being applied in other ways. At Juneau, Alaska, FAA Capstone officials and airport personnel have launched a project that places the airborne equipment in airport vehicles. This has two benefits. First, in low visibility it alerts pilots of approaching ADS-B-equipped aircraft of the whereabouts of vehicles and, especially, their proximity to the runway.
Shipping giant UPS and partner Aviation Communication and Surveillance Systems (ACSS) last month submitted the approval paperwork to the FAA for a suite of ADS-B (automatic dependent surveillance-broadcast) avionics intended to streamline busy operations at UPS’s Louisville, Ky. hub.
At the FAA’s Joint Planning and Development Office Day on Capitol Hill recently, Administrator Marion Blakey introduced two NextGen future ATC documents. First was the agency’s 41-page 2008-2012 Flight Plan, which announced projects such as the statewide Alaska ADS-B project.
There was good news for Alaskan pilots last month, when FAA Administrator Marion Blakey introduced the agency’s draft 2008-2012 Flight Plan, along with the NextGen Concept of Operations, to Congress.
Since everyone agrees that rapidly increasing traffic volumes over the next 20 years will demand the FAA’s NextGen solution–or something very similar–it came as a surprise to hear a recognized authority ask whether there actually will be such a system. This is the almost unthinkable question that Neil Planzer, Boeing Phantom Works v-p for strategy and advanced air traffic management, posed at an Atlantic City, N.J.
United Parcel Service will save millions of dollars a year by introducing technology that is designed to provide improved aircraft spacing for arriving aircraft.
There was good news for Alaskan pilots last week, when FAA Administrator Marion Blakey introduced the agency’s draft 2008-2012 Flight Plan, along with the NextGen Concept of Operations, to Congress.
After spending a decade studying automatic dependent surveillance-broadcast (ADS-B) technologies, Russia and Sweden have signed an accord to bring to their part of the world the necessary ground infrastructure for support of the concept.
U.S. and European aviation authorities agree that air traffic will double, possibly even triple, by 2025, and air traffic managements worldwide are busy devising solutions to meet this challenge, with new technologies and new procedures expected to be introduced gradually in the next several years.
