CONFLICT SITUATIONAL AWARENESS & ALERTING (CSA)
Conflict Situational Awareness (CSA) is an alerting algorithm which provides ADS-B traffic alerting similar to
the TAS
system discussed previously.
When a TA occurs with is equipment, the displays a ‘TRAFFIC’ annunciation and provides a voice alert. This
annunciation and voice alert is the same as the alerts issues by the Garmin GTS 800 TAS discussed previously.
The own aircraft altitude above terrain determines the sensitivity of the CSA algorithm to minimize nuisance
alerts. 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:
