AIR Traffic (AT‑2)

AIR Traffic (AT‑2)

The AIR Traffic (AT‑2) is a dual‑link ADS‑B receiver. It simultaneously receives 1090 MHz and UAT 978 MHz ADS‑B signals and passive Mode‑S transponder returns (providing range and altitude only). It also offers subscription‑free FIS‑B weather and TIS-B traffic data where available. Compact and rugged, the unit measures 122 × 61.5 × 30.8 mm (4.80 × 2.42 × 1.21 in), weighs approximately 180 g (0.39 lb), and is built for hidden or remote installation.

AT‑2 is easy to install as a remote unit. Mounts, cables, and accessories are available. Additionally, AT-2 integrates seamlessly with AIR Traffic Displays (different sizes available) into a single‑block installation where desired. The single block can be easily mounted in the panel, reducing the required installation work even more.

AT‑2 delivers greater traffic reception than most systems—including SIL=0 ADS‑B and non‑ADS‑B detection. Configuration and diagnostics are performed wirelessly via AT‑2’s Wi‑Fi® network and web‑based interface. It supports RS‑232, ARINC429, Wi‑Fi®, Bluetooth®, and standard protocols including GDL90, Garmin TIS, FLARM NMEA, along with an audio output for optional voice alerts. AT-2 logs flight tracks (KML and IGC), includes antenna‑health monitoring, and features discrete I/O for airframe switches and external device control.

Manufactured in Germany in AIR Avionics’ PART-21 approved production facility and backed by a two‑year warranty, AIR Avionics’ award-winning customer support, a quick exchange programme, and PART‑145 certified repairs, AT-2 integrates into a proven ecosystem that is trusted by pilots worldwide.
