The FAA has issued a supplemental type certificate (STC) for installation of a Garmin G700 TXi flight display system in the Learjet 35/35A and 36/36A equipped with JET FC-530/535 autopilots.

The 10.6-inch TXi displays feature touchscreen interfaces and replace the Learjets’ original mechanical instruments, including the airspeed indicator, altimeter, attitude director indicator, horizontal situation indicator, vertical speed indicator, and other instruments. Supporting the TXi displays are associated attitude, heading, and air data sensors, along with a GI 275 standby instrument and dual GTN 750Xi touchscreen navigators. The company will make the STC available to Garmin dealers and plans next to certify the TXi package in Learjet 35/36 models with JET FC-200 autopilots.
