I thought the only disadvantage of 1090ES vs UAT was that the former
couldn't receive TIS-B traffic. If it's true then why wouldn't the
ultimate future-proofed solution be a TT21/22 and a PowerFlarm. You
can get them both within a few months and the will provide the best
coverage through the transition. That plus with 1090ES being
mandatory in 2020 for big iron you have optimal solutions against the
two scariest threats (other gliders because of the density and
proximity issues in remote locations and airliners because hitting one
of those is a buzz-kill for the whole sport). At the same time you get
PCAS to cover all the slow adopters. Plus you get integration into
glider nav systems and glider-specific collision modeling.

What did I miss?
The included IGC logger.
