Garmin GTS Traffic Systems
SYSTEM OPERATION
Operating Modes
The system typically powers up in Standby mode. In Standby mode, the
system is powered on, but no traffic surveillance functions are performed.
Operate mode is the normal mode for operations. All active and passive
traffic surveillance functions are performed in Operate mode.
Self-test mode is a manually-selected mode that briefly performs a test of the
system. Refer to the self-test section of this guide for additional information.
If the system detects a fault that will prevent normal operation, the system
will enter and remain in Fail mode.
Control of Modes
Standby, Operate, and Self-test modes may be manually selected via system
controls. The controls are either integrated with the traffic display(s) or installed
as external control switches.
Traffic Information
The function of the GTS Traffic System is to provide information regarding
nearby traffic to the crew. For each traffic target that is tracked by the GTS,
the system computes the bearing, range, relative altitude, and vertical trend
for the target. Relative altitude and vertical trend are available for targets with
altitude reporting capability. This traffic information is displayed to the crew
on an interfaced display. Bearing and range are shown on a two-dimensional
(top-down) map. Relative altitude, when available, is displayed above or below
the corresponding target symbol in hundreds of feet. When the target is above
the own aircraft, it is preceded by a “+” symbol; a minus sign “-” indicates the
target is below the own aircraft. A vertical trend arrow to the right of the intruder
symbol indicates climbing or descending traffic with an upward or downward-
pointing arrow.
