Traffic Warning Window
When the unit is not on the traffic page and a traffic
threat is imminent, the Traffic Warning Window is dis-
played. The Warning Window shows a small map and
can display the Traffic Page (if the user presses
ENT
) or
return to the previous page (if the user presses
CLR
).
Traffic Warning Window
NOTE:
The Traffic Warning Window is disabled when
the aircraft ground speed is less than 30 knots or when
an approach is active, unless the unit is configured for
helicopter operation as noted by the helicopter ownship
icon.
NOTE: GTS 8XX series unit data is only displayed on the
Map Page if suitable aircraft heading data is available.
See the Garmin 400W or 500W Series Installation Manu-

TAS Symbol Traffic Type
Description
Other Traffic
Symbol
The hollow white (may be configured as cyan) diamond represents traffic detected within
the selected display range that does not meet the criteria for a TA or a PA and does not
pose an immediate collision threat.
Proximity
Advisory (PA)
Proximity Advisories (PA) are displayed as solid white (may be configured as cyan)
diamonds. PA’s are defined as traffic within 6 NM, within 1200 feet of vertical separation,
and are not a Traffic Advisory (TA)
Traffic
Advisory (TA)
A Traffic Advisory (TA) is generated when the GTS 8XX predicts that an intruder aircraft
may pose a collision threat. A solid yellow circle represents an intruder aircraft that meets
the TA criteria as described in the TA Alerting Conditions section. A TA consists of the traffic
symbol and an aural alert (e.g., “traffic, 12 o’clock, high, 3 miles”).
Out-of-
Range Traffic
Advisory
This solid yellow half circle appears (on the outer range ring) under the same conditions
and has the same urgency as a TA. Its appearance differs from the TA only to signify that
the intruder is outside of the current range of the Traffic page.
