The GTX 345 receives ADS-B transmissions from other ADS-B Out equipped aircraft, ADS-R, andTIS-B information from ground stations. Traffic information received from these transmissions supply compatibleADS-B In data to CDTIs to show the pilot.1.4.3 Installation Approval for ADS-B SystemsThe conditions and tests necessary for TSO approval of the GTX 3X5 are minimum performance standards. It is theresponsibility of the installer to determine if the aircraft installation conditions are within the TSO standards. TSO unitsmust have separate approval to install in an aircraft. The GTX 3X5 can be installed only in compliance with14 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 notapproved 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 with14 CFR 91.227 and to make sure compatibility between the GTX 3X5 and the ADS-B Out equipment. For compatibleequipment that is applicable for 14 CFR 91.227-compliant installations in accordance with AC 20-165A refer toGarmin ADS-B Out Compatible Equipment.
