FLARM is fitted to very few aircraft other than gliders and glider tugs in UK, although in Europe (especially Alpine countries) a growing number of GA have it fitted.
FLARM's only built in output is serial (RS232 at 19200 baud) datastream with open source format.
It is most useful (I would suggest) input to an MFD as an overlay on the Nav screen. Most soaring nav systems have the ability to do this.
For GA, I would suggest , TPAS info from a device like the Zaon XRX is even more useful. Higher level Garmin portables (496 up) can do this.
Most useful would be the ability to display TPAS and FLARM; the only device I know with software support for both is the Flymap L. I have done an installation of the relevant bits on an Aquila AT1 to do this, and it works fine.
The problem of adding this capability to a certified avionics installation is the paperwok in interfacing non-certified devices to a certified installation. To put it kindly, EASA has not made this any easier.
