About the Cessna Citation CJ2

The Cessna Citation CJ2 is a light business jet that brought Citation performance and reliability to the entry-level corporate market when it entered service in 2000. Built by Textron Aviation, the CJ2 is the second member of the CitationJet family, stretching the original CJ1 fuselage by sixteen inches to seat up to eight passengers while retaining the simplicity and operating economics that made the Citation line the best-selling business jet family in history. Powered by two Williams FJ44-2C turbofans, the CJ2 cruises at 0.70 Mach and climbs to a maximum altitude of 45,000 feet, offering transcontinental range of approximately 1,550 nautical miles with four passengers.

The CJ2's appeal lies in its combination of single-pilot certification, modest operating costs, and genuine jet performance. It can access the same high-altitude airways and airports as much larger corporate aircraft while requiring only a 3,450-foot runway for takeoff. The type became a workhorse for fractional ownership operators, air charter companies, and owner-flown corporate flight departments seeking an economical step up from turboprops. Cessna delivered more than 350 CJ2 and CJ2+ variants before production ended in 2016, replaced by the updated CJ3 series.

The CJ2 remains popular in the pre-owned market for its straightforward systems, Garmin avionics, and Cessna's global support network. Its Proline 21 flight deck in later models brought glass-cockpit capability to the light jet segment, and the aircraft's docile handling characteristics made it a favorite among owner-pilots transitioning from piston twins. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
