Air Avionics TRX 1500

TRX-1500 is a collision avoidance system for remote installation. The system combines ADS-B and Transponder reception with a FLARM® transmitter and receiver. It features many interface options and is capable of sending traffic data to compatible traffic displays and portable moving-maps as well as professional avionics systems making integration into existing cockpits easy.

Easy Installation

TRX-1500 is compact, lightweight and only draws very little power. With its interfaces it can be effortlessly integrated into existing panels. At a weight of less than 180g it is even suitable for the 120kg class of microlight aircraft.


Traffic Detection

TRX-1500 receives the exact 3D-position of FLARM® and ADS-B Traffic as well as distance and relative altitude of Mode-S transponders. Additionally the own position is sent out to all FLARM® compatible systems - over 20.000 in use worldwide.



TRX-1500 features two independent traffic data channels for display systems or moving maps in NMEA or GARMIN® TIS® format and an audio output. In addition the TRX-1500A version has an ARINC429 interface integrated for connection to professional panel mount avionics like GARMIN® GNS® or GTN®.
