TRAFFIC SYMBOLOGY
Traffic information from the GTS 8XX is displayed on the 4XX/5XX unit using TAS/
TCAS symbology (Table 1) on a dedicated Traffic page, and on the moving Map Page.
The displayed traffic information generally includes the relative range, bearing, and
altitude of intruder aircraft.
The GTS 8XX also generates aural announcements heard
on the cockpit audio system.
Proximity Advisories and Other Traffic symbols normally
displayed in white may be displayed in cyan if configured for alternate traffic color (see
the applicable 4XX/5XX installation manual).

Traffic Type
Description
Traffic
Advisory (TA)
A TA (Traffic Advisory) 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.
Proximity
Advisory (PA)
Proximity Advisories (PA) are displayed as solid white (may
be configured as cyan) diamonds.
PAs are defined as
traffic within the 6.0-nm range, within ±1200 ft. of altitude
separation, and are not a traffic advisory (TA).
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.

TA ALERTING CONDITIONS
The GTS 8XX automatically adjusts its TA sensitivity level
(Table 2) to reduce
the likelihood of nuisance TA alerting during flight phases likely to be near airports.
