"our main concern was to ensure that
gliders are detectable by an aircraft
equipped with a traffic alert and collision
avoidance system (TCAS)"

Gliders are already kept well away from
air carriers by Class B and C.

That makes the primary beneficiaries of
the ANPRM private jet owners able to
afford TCAS - $30K to $200K before
installation.

As long as they're transmitting ADS-B,
anybody with PowerFLARM knows
exactly where they are from several miles
away and can avoid.

At least some air carriers are not transmitting ADS-B as of this writing. Southwest for example - none of their jets flying into and out of Reno show up on PowerFlarm. Biz jets seem to have a higher install rate than airlines.

So SouthWest isn't using their transponders these days?? Hope you report
that to FAA.

They of course have transponders, but only the most recent models of 737 have ADS-B.

Southwest still have quite a lot of -300 and -500 models which I believe will never be fitted with ADS-B. They will be retired by 2020.

The -700 and -800 models will be retrofitted with ADS-B by 2020. Some may have come with it from the factory (-800s?).
