Do the Trig transponders offer Extended Squitter ADS-B out?
As of 2010, Trig TT22 & TT31 transponders include support for Extended Squitter (ES) ADS-B Out. The software in the Trig transponders for the ES ADS-B Out provide all of the required parameters listed in EASA AMC20-24. AMC20-24 is ADS-B airworthiness approval for EASA. This “Acceptable Means of Compliance” spells out the performance requirements of such equipment. In order to utilize the ADS functions of the Trig transponders, a GPS receiver meeting specific criteria must be interfaced with the transponder. As of 2010, the Freeflight 1201 and NexNav 3101 are the only GPS receivers that can be used with the Trig transponders for this function.
