What do I need to do for the proposed regulations
you want to be seen by ADS-B and want to fly in specific transponder
required Airspace see exemption below.
You can put a TN72 into your certified glider but you cannot fly into ADS-B
designated airspace, only in areas where equipage is voluntary [for a glider].
But you will be seen!
Glider exemption for Transponders and ADS-B 2020
The regulation 14 CFR 91.225(e) allows aircraft not
certificated with an electrical system, including balloons and gliders, not
equipped with ADS-B Out to operate within 30 nautical miles of a Class B
primary airport—basically, within its Mode C veil—while remaining outside of
any Class B or Class C airspace. These aircraft can operate as high as 17,999
feet msl except above Class B or Class C airspace; they also can operate
beneath Class B and Class C airspace. Operationally the ADS-B Out rules mirror
the transponder equipage requirements in 14 CFR 91.215. Equipping with a
transponder now, and ADS-B Out by Jan. 1, 2020, allows for operations above
Class B and C airspace.
If you want to fly in airspace that now requires
After 2020 you will need a "2020 compliant" ADS-B Out system in your glider
wherever you need a transponder now. ADS-B out can provide long-range
visibility to gliders equipped with PowerFLARM and to other aircraft with
ADS-B In traffic systems. Gliders are partially, but not fully, exempt from
transponder and ADS-B Out carriage requirements. Gliders will require ADS-B
Out after January 1, 2020 for flight in or above class B
and within Class A airspace, and within some
Experimental gliders can use a TT22 Transponder and TN72 GPS to meet full
2020 ADS-B Out requirements. The TN-72 is used as a "meets
performance requirement of TSO-C145c" GPS source.good enough for install in an experimental
aircraft. These installations are done with the ADS-B Out system set to
transmit SIL=3 (Source Integrity Level). To do this your glider needs to go
thought the standard ADS-B Out FAA installation. You should complete. a check flight to validate the install against the FAA ADS-B system.
A SIL=3 ADS-B Out install, meets 2020 Out flight requirements, is visible to
PowerFLARM 1090ES , to ATC, and to a certified panel mount ADS-B In
traffic systems. A a TT21 can be upgrade to TT22 for around $900.

New installs of Trig transponders should be TT22 not a TT21 to give you
maximum flexibility in future. Trig's USA service partner can also upgrade

ADS-B Out installations may require you upgrade firmware on your Trig
transponder, TABS/SIL=1 use requires the TT21/TT22 has firmware 2.12 or
higher TC90 Control head is part of a TT22 and needs firmware upgrade, SIL=3/2020
compliant use requires firmware 2.7 or higher. Upgrading
the firmware requires a (no charge besides shipping) return to the USA
