The Citation CJ4 (Model 525C) is the final stretched version of the original 1992 Citation 525 model. The single-pilot light jet offering from Cessna shares the same fuselage cross-section, cockpit, and engines with the other Cessna Citation CJ models, the VLJ M2, and the shorter CJ3. Instead of the straight wing of the M2 and CJ3 models, the CJ4 is using a higher speed moderately swept wing.
The Citation CJ4 first flew on May 5, 2008, and deliveries began in 2010.
All Citation CJ models have inherited the 58-inch internal diameter circular cross-section fuselage of the 1971 Citation 500 model.
The Citation CJ4 all-new designed interior combines both elegance and comfort. the interior layout provides seating for up to ten passengers to work and relax comfortably. The standard configuration includes a forward galley with a side-facing seat, four club seats forward, two aft seats, and a belted externally serviced lavatory. The cabin management system is powered by Rockwell Collins Venue™ high-definition system
