AIRBORNE AND SURFACE APPLICATIONS
The UAT can help the pilot visually acquire traffic both in the air and on-the-ground. There are two ADS-B
applications or modes: Airborne Situational Awareness (AIRB) and Surface Situational Awareness (SURF). The
system automatically selects the appropriate application based on conditions.
The AIRB application is on when the aircraft is more than five NM and 1,500 feed above the nearest airport.
When the AIRB application is active, the system only displays traffic which is airborne.
The SURF application is on when the aircraft is within five NM and less than 1,500 feet above field elevation.
When the SURF applications is on, the system displays airborne and on the ground traffic. At a Traffic Map
Page range of two nm or less, the airport environment (including taxiways and runways) appears in addition to
traffic. The airport displays are derived from the SafeTaxi database. Refer to the Additional Features section for
more information about SafeTaxi displays.
NOTE: Do not rely on the solely on the traffic display to determine the runway alignment of traffic, especially
when runways are in close proximity to each other.
Due to the varying precision of the data received via ADS-B, ADS-R, and TIS-B, all traffic targets may not be
depicted on the traffic display. Because higher data precision is required for display in the SURF environment,
some traffic eligible for AIRB will not be displayed while SURF is on. Individual eligibility for AIRB and SURF
is depicted on the AUX-ADS-B Status Page, discussed later in this section.
