It depends on whether your TT-22 was pinged by Mode S or Mode C station. If pinged by a Mode S station it will reply Mode S with all the information. If pinged by a Mode C station it will reply Mode C without that information and even though properly configured with your ICAO address in both the flarm and Trig, it will still set off transponder warnings in nearby powerflarm units.

How often it is pinged by a mode C system is the question.
