Darryl,

Question regarding your statement that gliders are largely exempt from needing ADS-B Out to fly in 2020 inside some airspace which requires ADS-B Out.

I'm based inside a Mode C Veil. My glider has a TT21 equipped with the latest firmware 2.4 and 1.10 (I also have a PowerFlarm core providing ADS-B In).. Come 2020, since I have a Mode S transponder, I think I'll be required to install a C145a GPS that is known to work properly with my TT21.

Do you agree?

-John, Q3

It has always been the case that in an experiential aircraft can install a non-TSO (and non-meets performance of...) GPS source for ADS-B Out as long as all the basic things are done right and the aircraft correctly transmits the appropriate SIL parameters to advertise it is using a non-complaint GPS source. However that will *not* meet the 2020 carriage mandate, and allow that aircraft to fly in airspace requiring ADS-B Out (again which glider are largely exempt from).
