About the Cessna Citation CJ4

The Cessna Citation CJ4 is the largest and fastest member of the Citation Jet family, a light business jet that bridges the gap between entry-level Citations and midsize cabin-class aircraft. First delivered in 2010, the CJ4 stretches the fuselage of its CJ3 predecessor by nearly two feet, seats up to nine passengers, and is powered by twin Williams FJ44-4A turbofans that push it to a maximum cruise speed of 451 knots true airspeed at FL450. With a range of 2,165 nautical miles and a service ceiling of 45,000 feet, the CJ4 competes directly with the Embraer Phenom 300 and Pilatus PC-24 in the super-light jet segment.

Its Rockwell Collins Pro Line 21 avionics suite and single-pilot certification make it popular with owner-operators and fractional ownership programs alike. The CJ4 remains in production at Cessna's Wichita facility as part of Textron Aviation's lineup, with over 400 delivered worldwide. Its combination of speed, range, and operating economics has made it a workhorse for corporate flight departments, air ambulance operators, and charter services.
