The CJ was a clean-sheet design from Cessna over “legacy” models introduced in 1993. NASA assisted with a laminar-flow wing design to improve efficiency. The CJ series was certified for single-pilot operations from day one. The original cockpit has the standard 6-pack panel with basic radios and FMS, although most have been updated to incorporate Garmin GPS/NAV/COM units up to the GTN 750/750xi. Sixteen models have the G1000 cockpit conversion, and in January 2021 an STC was released for the G600TXI and GFC 600 autopilot.
