FLARM firmware updates

As with many other avionics systems, all FLARM devices require continual firmware updates. FLARM updates are free. This is made possible thanks to a common firmware in all different FLARM devices.

Previously, updates were required every 2-4 years according to an announced schedule. This was however problematic for many owners and maintenance organizations, since there was only a short time span in which the update could be made.

From the March 2015 Update, every FLARM device needs to be updated with the latest firmware version at least once per year (rolling 365 days). This should be part of the aircraft maintenance programme.

Firmware updates contain general improvements, collision algorithm improvements, radio protocol improvements and added features. The precise list of changes accompany each update.
