GARMIN GTS 800 TRAFFIC (OPTIONAL)
WARNING:
Do not rely solely upon the display of traffic information for
traffic avoidance maneuvering. The 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.
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 to 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 indi-
cation. Pilots should remain vigilant for traffic at all times.
NOTE:
TIS-A is disabled when TAS installed.
The optional Garmin GTS 800 is a Traffic Advisory System (TAS). It 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.
The GTS 800 is capable of tracking up to 45 intruding aircraft equipped with
Mode A or C transponders, and up to 30 intruding aircraft equipped with Mode S
transponders. A maximum of 30 aircraft with the highest threat potential can be
displayed simultaneously. No TAS surveillance is provided for aircraft without operating
transponders.
THEORY OF OPERATION
When the GTS 800 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 GTS 800 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.
