HAZARD AVOIDANCE
6.5 GARMIN GTS TRAFFIC
WARNING:
The Garmin GTS 800 Traffic Advisory System (TAS) is intended for advisory use only to aid
the pilot in visually acquiring traffic. No avoidance maneuvers should be based solely upon TAS traffic
information. It is the responsibility of the pilot in command to see and maneuver to avoid traffic.
information. It is the responsibility of the pilot in command to see and maneuver to avoid traffic.
NOTE:
Pilots should be aware of TAS system limitations. TAS systems require transponders of other aircraft
to respond to system interrogations. If the transponders do not respond to interrogations due phenomena
such as antenna shading or marginal transponder performance, traffic may be displayed intermittently, or
not at all. Aircraft without altitude reporting capability are shown without altitude separation data or climb
descent indication. Pilots should remain vigilant for traffic at all times.

NOTE:
Radar altimeter data is optional for the Traffic Advisory System (TAS). If radar altimeter data is
detected by the TAS at the beginning of a power cycle and that data is subsequently lost, the TAS will
declare a fault and will not provide traffic information.

NOTE:
TIS is disabled when TAS is installed.
The Garmin GTS 800 Traffic Advisory System (TAS) enhances flight crew situational awareness by displaying
traffic information for transponder-equipped aircraft. The system also provides visual and aural traffic alerts
including voice announcements to assist in visually acquiring traffic.
including voice announcements to assist in visually acquiring traffic.
The system is capable of tracking up to 45 intruding aircraft equipped with Mode A or C transponders, and up
to 30 intruders equipped with Mode S transponders. A maximum of 30 aircraft with the highest threat potential
can be displayed simultaneously. No traffic surveillance is provided for aircraft without operating transponders.
can be displayed simultaneously. No traffic surveillance is provided for aircraft without operating transponders.
THEORY OF OPERATION
When the traffic system is in Operating Mode, the unit interrogates the transponders of intruding aircraft
while monitoring transponder replies. The system uses this information to derive the distance, relative bearing,
and if reported, the altitude and vertical trend for each aircraft within its surveillance range. The traffic system
then calculates a closure rate to each intruder based on the projected Closest Point of Approach (CPA). If the
closure rate meets the threat criteria for a Traffic Advisory (TA), visual and aural alerting is provided.

TAS SURVEILLANCE VOLUME
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.
