FLARM in Stealth Mode at US 15M/Standard Nationals - Loved It!

9B, that's a really excellent point about ADS-B. Flarm Stealth mode may be a completely moot point in 5 years. Thanks for pointing it out.

Ultimately, FAA action notwithstanding, you will see gliders equipped with ADS-B Out. These will offer ranges of many tens of miles, not the 3-5 miles offered by Flarm. All of that traffic information will be picked up by your PowerFLARM and go straight to your flight display and will include gliders as well as any power traffic equipped with ADS-B 1090ES. There's no stealth mode for ADS-B and ADS-B doesn't discriminate aircraft type. It does, I believe, transmit an ICAO code.

I'm guessing we don't want to be in the position of requiring pilots to turn off their ADS-B gear or banning its installation. You might be able to filter out glider ICAO codes using some sort of registration database like FlarmNet (not a current Flarm capability), but that starts to get pretty complicated and I'd bet the FAA would have something to say about it.

Not an immediate issue, but 5 years from now it could be very real.
