ADS-B WITH TAS
When an optional Traffic Advisory System (TAS) is also installed and operating with the UAT, the UAT
receives traffic from the active traffic system and attempts to match (or “correlate”) this traffic with ADS-B
traffic the UAT is tracking. When a correlation is made, only the traffic with the most accurate information
is displayed to the flight crew. Any traffic that is not correlated (i.e., only detected by one system but not the
other) is also displayed for the flight crew. This correlation of traffic by the UAT improves the accuracy of the
traffic displayed, while reducing the occurrence of the same aircraft being displayed twice.
NOTE: When operating on the edges of ATC radar coverage or when using an optional active traffic system
providing intromittent traffic data, a single aircraft may be briefly or periodically depicted as two aircraft on
the display.
Either the TAS or the UAT unit can issue a traffic alert. If both systems determine an alert is necessary, and
the traffic is correlated, only the TAS-generated alert is issued. If traffic is not correlated, and both systems
determine an alert is necessary, the TAS-generated alert occurs first, followed by the UAT-generated alert.
CONFLICT SITUATIONAL AWARENESS & ALERTING
Conflict Situational Awareness (CSA) is an alerting algorithm which provides ADS-B traffic alerting similar to
the TAS systems discussed previously.
The UAT issues a voice alert when a Traffic Advisory (TA) is displayed, for example “Traffic! Two O’clock,
Low, Two Miles.”
The own aircraft altitude above terrain determines the sensitivity of the CSA algorithm to minimize nuisance
alerts. Radar Altitude (if available), Height Above Terrain, and Geodetic Sea Level (GSL) altitude are used to
adjust the sensitivity of the CSA algorithm in accordance with the following table:
