ADS-B Capabilities

ADS-B technology is used to improve situational awareness and flight safety. With ADS-B capabilities,
position, velocity, and heading information are automatically transmitted to other aircraft and ground
stations. ADS-B provides automatic transmission of aircraft information without a request.
1.4.1 ADS-B Out
When properly installed with a GPS position source, meeting the guidance of AC 20-165 the GTX 335 and
GTX 345 include ADS-B Out capabilities. See
GTX 345 will broadcast the position, velocity, and heading information using the mode S transponder
transmitter.
1.4.2 ADS-B In
The GTX 345 includes 978 MHz UAT and 1090 MHz receivers for ADS-B In capabilities. The GTX 345
can receive airborne position from other aircraft with either the UAT or 1090 MHz receivers. The
GTX 345 can receive FIS-B information from ground stations.

TIS System Capabilities

The GTX 3x5 provides uplink information of nearby traffic from the TIS. TIS is a ground-based service
providing relative location of all transponder equipped aircraft within a specified service area. The TIS
ground sensor uses real time track reports to generate traffic notifications. TIS provides a graphical display
of traffic advisory information in the cockpit for non-TCAS equipped aircraft.
Advisory traffic information is available to aircraft equipped with a Mode S data link such as the Garmin
GTX 335 or GTX 345. Advisory traffic information may be displayed on a Garmin 400W/500W Series
unit.
The GTX 3x5 unit can be incorporated into installations with other compatible control/display units such
as the Garmin GNS 480 (CNX80), GTN 6XX/7XX, GMX 200, and MX20 MFD.
Surveillance data is provided for transponder equipped aircraft within the coverage volume. Aircraft
without an operating transponder are invisible to TIS. TIS displays traffic within seven nautical miles from
3000 feet below to 3500 feet above the requesting aircraft. The pilot sees the location, relative direction
and altitude of other aircraft.
