Can anyone say if a Trig TT22 with TN70 will provide collision warnings?


The TT22 and TN70 gives you ADS-B Out only, unlike your GTX-345 that does ADS-B Out/In (1090ES Out and 1090ES In and UAT In). Glider pilots would normally get ADS-B In via a PowerFLARM (1090ES In only) or if they have room for a separate display then in some cases a Stratus or Stratux receiver (and if you do that get a dual link receiver).

Powerflarm is not a good ADS-B IN solution. It does not see UAT equipped aircraft, nor does it support ADS-R or TIS-B, which makes UAT and conventional transponder equipped aircraft visible to ADS-B IN equipped AC (as long as those aircraft are also ADS-B OUT equipped).

An ADS-B receiver (SCOUT, Stratus, etc.) coupled with an application like Foreflight or FltPlan Go on a smartphone or tablet provides an economical ADS-B collision warning system for those pilots who have an ADS-B out equipped glider.
