Flarm collision alert from Tow Plane ADS-B

I don’t see the option to enter ADS-B info in flarmnet. This could be useful though. Or perhaps flarm displays already recognize the contest ID for an ADSB target if their flarm already registered in flarmnet?

Just register as you would a Flarm and use your ICAO address as FLARM ID.

That's all fine and good, but I doubt that will matter to the OP whose
complaint was the constant alarm.

A glider tow is a formation flight and, in a formation flight, everyone
except the leader turns off his transponder (sets it on Standby, I'd say
the same for ADS-B and/or Flarm) to avoid mucking up the radar screens
on the ground and in the Flarm in the glider. At least that's the way it
was done when I was doing it for a living.Â* My suggestion would be for
the glider to turn off his Flarm until after releasing and gaining safe
spacing from the tug.Â* If it's a brick wired to the avionics bus, put a
switch in series with the power line.Â* Problem solved.

Flarm does not alarm when you are following another flarm equipped glider at 200 ft, so it should not following a tow plane either. If flarm uses the ICAO address it could identify the towplane as a towplane and treat it accordingly.

A switch in the power line to the Flarm isn't going to help if you are depending on it for a valid IGC flight log.

But Flarm, in its current state of development, has no obvious way to do this. The flarmnet database resides in whatever display you are using, not in the flarm.


T8

I wired my Flarm with double pole, 3 position switch. The first pole powers the brick and the second pole powers the Flarmview display. In the middle position, the PowerFlarm Core is on, but the display is off. In the full up position both are On. This allows me to kill the display without turning off my Flarm which provides Flarm visibility to others.

I feel you pain, jfitch, but I think the OP was complaining about the
ADS-B output from the tug being alarmed on his Flarm.Â* The way everyone
complains about loggers, I'd think he'd have an alternate, as in a
vario, flight computer, portable logger, etc...

Or the OP could simply disable ADS-B targets but that would remove
protection from ADS-B equipped but non-Flarm-equipped aircraft.
