Hazard Awareness
Traffic Application Failures
During normal operation, the "ADS: On" status annunciation means that both AIRB
and ATAS applications are active. In the rare event of an application failure, it is
possible that only one of the applications may be active. The unit provides indications
to reflect which application is no longer operational.
•
ADS field indicates "On"
•
If AIRB is active and ATAS is failed, the unit displays the system message:
"ADS-B traffic alerting function inoperative"
•
If AIRB is failed and ATAS is active (and still capable of providing a no-bearing
aural alert), "Unavailable" annunciates across the traffic display
