Operational Applications |
The following operational capabilities of Automatic Dependent Surveillance-Broadcast (ADS-B) aircraft-to-aircraft, aircraft-to-ground, and uplink services delivery are supported in the deployment of ADS-B. As additional capabilities mature, this page will be updated.
[Top][ADS-B][TIS-B][FIS-B][Flight Monitoring]
Air-to-air, air-to-ground, and ground-use applications are for situational awareness purposes only. This includes the detection and display of suitably equipped airport surface vehicles to support enhanced “see and avoid.”
For air-to-air applications, the Universal Access Transceiver (UAT) data link is not intended to provide information for guidance or control purposes. Rather, it is intended to provide information to enhance pilot/flight deck situational awareness.
ADS-B services have been approved for air traffic surveillance use ONLY in Alaska.
Additionally, there are several efforts underway to further mature advanced ADS-B applications such as air-to-air in-trail spacing, delegated separation, and airborne cockpit management. Operational approval is required for use of these applications in commercial service.

TIS-B was developed to support ground-to-air and ground-to-ground surveillance services. This technology supports the visual acquisition of proximate aircraft for enhanced “see and avoid” in the air and on the airport surface, dependent upon an airport ground radar system and an ADS-B ground based transceiver (GBT) co-located on the same airport. These two TIS-B applications are intended to improve the pilot’s ability to visually see other traffic in the air and on the airport surface so that pilots can more effectively apply the traditional “see-and-avoid” techniques.
TIS-B is NOT intended to be used as a collision avoidance system and does NOT relieve the pilot of responsibility to "see-and-avoid" other aircraft. (See Aeronautical Information Manual, Paragraph 5-5-8, “See and Avoid”). TIS-B shall not be used for avoidance maneuvers during times when there is no visual contact with the intruding aircraft. No avoidance maneuvers are provided for, nor authorized, as a direct result of a TIS-B target being displayed in the cockpit.

FIS-B products are advisory and will be provided free of charge using the UAT data link. Initial product offerings include:
Graphical Next Generation Radar (NEXRAD) precipitation,
Textual Meteorological Aerodrome Report (METAR) and Special Reports (SPECI) and,
Textual Terminal Aerodrome Forecast (TAF).
The following products are also available in Alaska and will be available everywhere in 2006:
Textual Airman’s Meteorological Information (AIRMET),
Textual Significant Meteorological Information (SIGMET),
Textual Convective SIGMET and,
Textual Winds Aloft.
Other products will be announced as part of future revisions to this site.

ADS-B data can be used for flight monitoring, flight management, surface traffic airline asset management, and other safety and efficiency purposes contingent upon appropriate FAA authorization and approvals.
