Hi All,
Of around 40 flexwings of various ages and types at AlanG and I’s local club, a dozen or more now run ADSB Out via Trig TT21 Transponders using a variety of GPS sources, including PilotAware, various dedicated GPS devices or in a handful of cases, Trig’s own (certified) TN72. Irrespective of the GPS source, all are partnered by PilotAware units providing additional low-cost visibility and acting as multi-mode receivers.
Mine was the second aircraft at the field set up for ADSB Out - way back in May 2015 - by installing a Trig TT21 with a dedicated (uncertified) Byonics GPS4 GPS source, to take part in local Project Eva trials run up here in Scotland by Trig. It was immediately successful, and I have since been involved with a significant number of similar installs using a variety of GPS sources and can verify that Trig’s TT21/TT22 devices are easy to set up and in my experience always work effectively. Trig’s larger TT31 stack devices are also similarly easy to adapt and effective, though owners tend to opt for Trig’s TN72 or fully certified TN70 GPS sources (and not to my knowledge in flexwings).
Hope this helps
Regards
Peter
