Hazard Avoidance
T A
RAFFIC DVISORIES
ADS-B traffic devices automatically adjust the Traffic Advisory (TA) sensitivity level
to reduce the likelihood of nuisance TA alerts during various phases of flight. TAs are
issued for traffic when they are predicted to be within a specified volume of airspace
around your aircraft in a specified amount of time. The protected volume and time
interval varies based on the current geodetic altitude and groundspeed. Thus, the
protected volume of airspace increases with altitude and ground speed. Refer to the
following table for details.
The following Traffic symbols are displayed on the display when Synthetic Vision is
installed and enabled. See the Additional Features Section for more information about
Synthetic Vision.

TRAFFIC ALERTS (ADS-B TIS-B)
A traffic voice alert is generated whenever the number of Traffic Advisories on the
G3X Touch 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 voice alert is generated. If a second (or more) aircraft appears on
the screen, a new voice alert is sounded. Traffic Advisories can only be issued when the
GDL knows its own altitude and the altitude of the intruder aircraft.
