Following development of a fully integrated avionics suite for the Textron Aviation Cessna Citation CJ2 in March 2024, the upgrade has received FAA supplemental type certificate approval for the Citation CJ1. The upgrade replaces all of the original avionics with Garmin touchscreen TXi displays, GTN Xi navigators, GFC 600 digital autopilot, and any additional optional equipment.
While the upgrade package includes 10.6-inch TXi displays, buyers can opt for Garmin’s 12.1-inch displays for the primary and multifunction displays (PFD and MFD). The standby flight instrument is a Garmin GI 275 mounted on the pilot’s side, and a second GI 275 on the copilot side is an option. The pilot PFD and GI 275 are powered by the CJ1's emergency bus, while the copilot's GI 275 has an internal backup battery. Heading, altimeter, airspeed, and altitude selections are synchronized between the GI 275 and the PFD, and synthetic vision is also available for display on the GI 275.
