The TT21 is a two-part low power transponder system with a compact control head that includes an integrated altitude encoder. The low 130 watt power output qualifies this unit as a Class 2 transponder which may be used on aircraft cruising slower than 175 knots, and operating below 15,000 feet, IFR or VFR. Its compact size and efficiency makes the TT21 ideal for use via an auxiliary battery in gliders, balloons, or foot launched flight. It features simple operation and a clear and bright display, with manual dimming, which makes it easy to read in all lighting conditions. The control head is splash proof making it ideal for operations in an open cockpit and seaplane.
Mode S technology provides visibility to ATC, commercial, and military traffic. Trig transponders are ADS-B Out capable, with a suitable GPS - sold separately, meeting the latest FAA certification standard for ADS-B known as TSO-C166b.
Customers in the U.S. should be aware that FAA, Federal Aviation Regulations (FAR) 91.227 requires that a compliant ADS-B Out solution use a Class 1 transponder. The TT22 is a Class 1 device and meets this requirement. The TT21 is a Class 2 device and does not meet this regulation."" The FAA has stated that Class 1 transponders must be used to be 2020 compliant. For this reason, it is recommended that the TT22 unit be used instead. (see EDMO#00772-00).
