SurveillanCe
The GTS 800 surveillance system monitors the airspace within ±10,000 feet of own
altitude. Under ideal conditions, the GTS 800 unit scans transponder traffic up to 12
nm in the forward direction. The range is somewhat reduced to the sides and aft of
own aircraft due to the directional interrogation signal patterns. In areas of greater
transponder traffic density or when TCAS II (Traffic Alert and Collision Avoidance
System II) systems are detected, the GTS 800 automatically reduces its interrogation
transmitter power (and therefore range) in order to limit potential interference from
other signals.

yMBology
The GTS 800 uses symbology to depict intruding traffic using the symbols shown
below.
Symbol
Traffic Advisory.
Traffic Advisory out of the selected display range. Displayed at outer range
ring at proper bearing.
Proximity Advisory.
Non-Threat Traffic.
A Traffic Advisory (TA), displayed as a yellow circle or triangle, alerts the crew to
a potentially hazardous intruding aircraft, if the closing rate, distance, and vertical
separation meet TA criteria. A Traffic Advisory that is beyond the selected display range
(off scale) is indicated by a half TA symbol at the edge of the screen at the relative
bearing of the intruder.
