What is FLARM?

FLARM is an award-winning and affordable collision avoidance system for General Aviation, light aircraft and UAVs. Since its invention in 2004, over 25.000 FLARM systems have been installed in aircraft worldwide.

Originally developed for gliders and sailplanes to solve the inherent shortcomings of TCAS, FLARM has today expanded also into other aviation domains.



FLARM can be extended with additional features, such as Obstacle databases, IGC approval, and much more.

All features can be purchased in our webshop and then easily downloaded as a license file.

The license file is then put in the FLARM device via USB stick or microSD card and activated immediately.GO TO SHOP
