AIR Traffic (AT‑1)

AIR Traffic (AT‑1)

AIR Traffic (AT‑1) is a traffic detection system engineered specifically for European airspace, combining FLARM transmitter/receiver, ADS‑B (1090 MHz), and Mode‑S reception into one remotely installable unit. It detects aircraft transmitting FLARM or ADS‑B, and also computes the horizontal/vertical range of Mode‑S targets. Used with compatible displays (e.g. ATD‑57/80), it detects over 90 % of weekend traffic below FL100 in Europe.

With built‑in antenna diversity, high‑sensitivity receivers, and a voice‑alert interface, AT‑1 increases situational awareness and reduces pilot workload. AT-1 has comprehensive interfaces that include RS‑232, ARINC429, Wi‑Fi, Bluetooth, and protocols such as GDL90, FLARM NMEA, ASTERIX21, TIS, and more. It virtually works with any avionics system for GA that can show traffic.

With its robust connectors and a compact form factor (122 × 61.5 × 30.8 mm / ~180 g / 0.39 lb), AT‑1 is easy to install as a remote unit. Mounts, cables, and accessories are available. Additionally, AT-1 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. The configuration via Wi‑Fi® allows a simple setup using any web browser.

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.
