Dependent Surveillance-Broadcast (ADS-B) Services a. Introduction. 1. Automatic Dependent Surveillance-Broadcast (ADS-B) is a surveillance technology deployed throughout the NAS (see FIG 4-5-6). The ADS-B system is composed of aircraft avionics and a ground ... other ADS-B services. This information is transmitted at a rate of approximately once per second. (See FIG 4-5-7 and FIG 4-5-8.) 2. In the United States, ADS-B equipped aircraft exchange information…

flight requests for “immediate” deviation from the ADS-B Out requirements may be approved by ATC only for failed equipment, and may be accommodated based on workload, alternate surveillance availability, or other factors. All other requests for deviation must ... least 1 hour before the proposed operation, following the procedures contained in Advisory Circular (AC) 90-114, Automatic Dependent Surveillance-Broadcast Operations…

RADAR CONTACT [ICAO]- The situation which exists when the radar blip or radar position symbol of a particular aircraft is seen and identified on a radar display. RADAR CONTACT LOST- Used by ATC to inform a pilot that the surveillance ... data used to determine the aircraft’s position is no longer being received, or is no longer reliable and radar service is no longer being provided. The loss may be attributed to several factors including the aircraft merging with weather…

NOTE-Radar ATC facilities normally display and monitor both primary and secondary radar as well as ADS-B, except that secondary radar or ADS ... some circumstances outside of Class A airspace (beyond primary coverage and in en route areas where only secondary and/or ADS-B is available). Secondary radar and/or ADS-B may also be used outside Class A airspace as the sole display…

that coincides with the canceling signal of the MTI (tangential or “blind” speed) may not be displayed to the radar controller. (d) Relatively low altitude aircraft will not be seen if they are screened by mountains or are below ... radar beam due to earth curvature. The historical solution to screening has been the installation of strategically placed multiple radars, which has been done in some areas, but ADS-B now provides ATC surveillance in some areas with challenging terrain…
