The TT31 class leading, Mode S transponder is a popular retrofit transponder for legacy transponders. With plug and play compatibility, the TT31 installs directly into an existing KT76A, KT76C, and KT78A mounting trays from Bendix King which significantly reduces installation time and cost — and provides pilots with a 1090ES ADB-S capable technology. Part 00220-00 is the Transponder only and does not include the mounting tray, connector kit or installation manuals.
