FLARM devices transmit traffic and collision data using FLARM-specific NMEA sentences over RS-232 (PFLAx sentences). The ICD and configuration specification is freely available to developers following an individual request.
If you are developing a new display or want to integrate FLARM data into an already existing display, the ICD should be used together with the FLARM Compatible Certification Specification (document FTD-013). Equipment which conforms to the certification specification can be marketed as FLARM Compatible and use the FLARM Compatible logo.
The request forms for the mentioned documents are available at the bottom of the Manuals and Documents page.
You should also note that each FLARM devices must be connected to a certified primary display, as defined in FTD-013. In additions, installers may connect FLARM devices to other (secondary) displays to e.g. show proximate traffic.
On the Displays page, there is some additional information, as well as a current list of certified displays.
Contact us if you have any questions regarding certification.
