Citation CJ4

The Citation CJ4 crowns the CJ series with greater range, speed, and refinement—bridging the gap between light and midsize jets while preserving the efficiency and single-pilot capability that define the Citation line. Featuring a moderately swept Sovereign-style wing and a scaled-up T-tail, the CJ4 delivers smoother handling, higher cruise speeds, and excellent high-altitude performance. Its fuselage is 21 inches longer than the CJ3, retaining the same cross section while offering expanded legroom and storage. Powered by FADEC-equipped Williams FJ44-4A engines, the CJ4 combines robust performance with advanced systems and a refined flight deck built around the Collins Pro Line 21 avionics suite. Additional design enhancements—such as heated windshields and raised cabin windows for improved passenger visibility—underscore its premium feel. Certified for single-pilot operation, the CJ4 climbs directly to 45,000 feet in 28 minutes and cruises at 435 knots, offering performance that rivals larger jets while maintaining Citation efficiency and reliability. Sophisticated, capable, and fast, the Citation CJ4 remains the flagship of the CJ family and a benchmark for modern light jet design.
