ADS-B Capabilities
1.4.1
ADS-B Out
The GTX 335 and GTX 345 include ADS-B Out capabilities when installed with an approved internal or
external GPS position source.
1.4.2
ADS-B In
The GTX 345 includes receivers for both the UAT and the 1090 MHz frequency bands for all ADS-B In
data reception capabilities. The GTX 345 receives ADS-B transmissions from other ADS-B Out equipped
aircraft, ADS-R, and TIS-B information from ground stations. Traffic information received from ADS-B,
ADS-R, and TIS-B transmissions supplies compatible ADS-B In data to CDTIs to show the pilot.
1.4.3
Installation Approval for ADS-B Systems
The conditions and tests necessary for TSO approval of the GTX 3X5 are minimum performance
standards. It is the responsibility of the installer to determine if the aircraft installation conditions are
within the TSO standards. TSO units must have separate approval to install in an aircraft. The GTX 3X5
can be installed only in compliance with 14 CFR Part 43 or the applicable airworthiness requirements.
All GTX 3X5 unit functions are design-approved under the TSO. Changes or modifications to any unit that
are not approved can void the compliance to necessary regulations and authorization for continued
equipment usage.
It is the installer’s responsibility to make sure the ADS-B Out system installation is compliant with
14 CFR 91.227 and to make sure compatibility between the GTX 3X5 and the ADS-B Out equipment.
Refer to Garmin ADS-B Out Compatible Equipment, for compatible equipment that is applicable for
14 CFR 91.227-compliant installations in accordance with AC 20-165A. FIS-B information is for pilot-
planning and pilot near-term decisions. The information shown are areas of inclement weather that are out
of visual range or are not easily seen.
1.5
FIS-B Capabilities
The GTX 345 receives FIS-B information from UAT ground stations in the United States. A direct line-of-
sight between the ground station and aircraft is necessary to receive FIS-B data. The data is not available at
ground level in some locations. The GTX 345 supplies the data to compatible displays. Depending on the
CDTI it can show:
•
NOTAM (includes TFRs)
•
AIRMET
•
SIGMET
•
SUA
•
METAR
•
TAFs
•
PIREP
•
Winds/Temps Aloft
•
