TRAFFIC ALERTS (ADS-B TIS-B)
A traffic audio alert is generated whenever the number of Traffic Advisories on the
G3X display increases. Limiting Traffic Advisories only reduces the "nuisance" alerting
due to proximate aircraft. For example, when the first Traffic Advisories appear on the
display, the user is alerted audibly. So long as a single aircraft remains on the display,
no further audio alert is generated. If a second (or more) aircraft appears on the
screen, a new audio alert is sounded. Traffic Advisories can only be issued when the
GDL 39 knows its own altitude and the altitude of the intruder aircraft.
If the number of Traffic Advisories on the traffic display decreases and then increases,
a new audio alert is sounded. The traffic audio alert is also generated whenever TIS-B
service becomes available. The traffic audio alerts are as follows:
• "Traffic"—TIS-B/ADS-B traffic alert received.
• "Traffic Not Available"—TIS-B/ADS-B service is not available or out of range.
Disabling/Enabling the traffic alerts:

traffic alerts.
