Garmin GTS Traffic Systems 190-00587-02 Rev. E
SECTION 5 SYSTEM INTERFACES
The GTS Traffic System includes interfaces to various required and optional
aircraft systems.
5.1 Altitude Source
At least one pressure altitude source is required for system operation. The
pressure altitude source is compared to the pressure altitude replies from other
aircraft to calculate their relative altitudes. Pressure altitude interfaces are
available from a serial altitude encoder or digital air data computer.
5.2 Transponder Interface
All GTS Traffic Systems except the GTS 800 require an interface to a
compatible Mode S transponder. The transponder interface allows the high-
power GTS systems to determine how many TCAS-equipped aircraft are in
the area. To reduce frequency congestion, transmit power is adjusted based on
the number of other TCAS-equipped aircraft in the area. The GTS 800 systems
transmit at a lower power level and do not require a transponder interface.
5.3 Traffic Display
At least one traffic display is required, and multiple traffic displays are
supported. The traffic display shows a two-dimensional (top-down) view of
traffic that is detected by the GTS system. Bearing, distance, relative altitude, and
vertical trend can be depicted on the traffic display. When the ADS-B In function
is installed and active, additional data provided by ADS-B (e.g. directionality) is
shown on compatible displays. Some traffic displays include integrated controls
for selecting the system operating mode and altitude filter. For details on the
capabilities of a compatible traffic display, refer to the documentation for that
display.
Contact your Garmin dealer to learn which displays are compatible with
the GTS systems. Some displays may require the purchase and installation of
additional modules and/or software.
5.4 Audio System
The GTS must be interfaced to an audio system so that traffic advisory aural
alerts and self-test messages can be heard by the crew.
