Maximizing efficiency and comfort while providing state-of-the-art technology, the Citation CJ4 makes this CJ the most advanced to date. The updated aircraft is the largest yet, with an elevated T-tail increasing its aerodynamics. It has also been updated with a Williams FJ44-4A engine for superior performance. The modified speed and range means this jet delivers in more ways than one. It has standard single-point refueling capability designed to minimize crew supervision, allowing an additional 1,000 pounds of payload with a full fuel tank. Its 17-foot cabin has been stylishly redesigned with the latest technology and comfort available. The Cessna parts used for this jet are tried and tested, guaranteeing quality and safety.
