Duncan Aviation Adds Garmin Flight Deck Upgrade for CJ1

Duncan Aviation has expanded its Garmin modernization program to include the Cessna Citation CJ1, offering operators an all-Garmin integrated avionics suite designed to improve flight deck capability and situational awareness.

The package includes dual 10.6-inch or 12-inch Garmin G600 TXi flight displays, dual GTN 750Xi navigators (if not already installed), 7-inch TXi engine indication system display, GFC 600 digital autopilot, GMA 350 audio panel, and GI 275 standby instruments. Additionally, the system supports the optional GWX 8000 StormOptix weather radar and Garmin’s PlaneSync connected management platform.

The CJ1 was recently added to Garmin’s approved model list supplemental type certificate, which already included the CJ2. Duncan said several of its facilities—including satellites in St. Paul, Minnesota, and Denver, Colorado—have completed the full Garmin modernization on other aircraft types, such as the Pilatus PC-12, Beechcraft King Air 90/200, and Citation Excel/XLS.

Corporate jet captain Michael Kussatz said the GFC 600 autopilot provides particular operational benefits when paired with the GTN Xi navigators. “They offer vertical navigation descents, fully coupled go-arounds, and Garmin’s Electronic Stability Protection, which works in the background to nudge the aircraft back to a safe altitude during manual flight,” he said. “It can fly a range of approaches and holds, build custom holds, and includes emergency descent mode.”

Sales manager Nate Klenke added that the system “tracks weather, traffic, and position with precision” and “performs flawlessly under high workload while safeguarding the aircraft in manual flight.” Duncan anticipates that future installations will take about eight weeks and can be scheduled at its main facilities or satellite locations.
