Cessna Citation CJ4 Review: A Premier Light Jet for Performance and Comfort
The Cessna Citation CJ4 has established itself as a leading light jet, gaining a strong following among both owner-pilots and professional flight crews. Since its entry into service in 2010, the CJ4 has carved out a profitable niche for Textron Aviation, offering a high-performing and versatile aircraft that caters to a range of aviation needs.
Design and Innovation
Priced at $9.41 million, the Citation CJ4 is the largest model in the CitationJet series and holds the distinction of being the company’s largest Part 23 aircraft. This model introduces several design innovations that distinguish it from earlier iterations. One key feature is its 12.5-degree wing sweep, which enhances aerodynamics, while still maintaining the short-field performance that the CitationJet line is known for. Additionally, the CJ4 incorporates upgrades such as electrically heated windshields and single-point refueling, replacing older bleed-air heating systems seen in models like the M2 and CJ3+. The CJ4 also comes with an externally serviced flushing lavatory, a feature that became standard after serial number 100.
Avionics and Technology
A standout feature of the CJ4 is its advanced Collins Pro Line 21 avionics suite, which includes the MultiScan radar. This radar technology combines short-, mid-, and long-range radar images, providing pilots with an integrated view of weather and turbulence, enhancing flight safety and comfort. The CJ4’s avionics are favored by professional pilots, particularly those accustomed to traditional flight management system (FMS) interfaces. Unlike some newer Citation models equipped with Garmin-based avionics, the CJ4 continues to use the Pro Line 21 system, which may influence its popularity among owner-operators who are more familiar with Garmin systems.
Since its launch, over 300 CJ4 units have been delivered, benefiting from the aircraft’s shared pilot certification with other Citation jets. This means pilots transitioning to the CJ4 require only two days of additional training, adding to the model’s appeal.
Cabin Layout and Comfort
The CJ4 offers two flexible cabin configurations: one with eight passenger seats and the other with nine. The eight-seat version includes a combination of single, double-club, and forward-facing seats, with an optional belted seat in the lavatory. The nine-seat layout replaces the entry-side seat with a two-seat couch, and if flown single-pilot, the right seat in the cockpit can be used for an additional passenger, bringing the total capacity to 10.
The cabin is well-appointed with 58 inches of width and 57 inches of height, providing ample room for passengers. Compared to competitors like the Phenom 300 and Pilatus PC-24, the CJ4 offers a comfortable, if slightly smaller, space. The CJ4’s extended fuselage over the CJ3 adds more space to the refreshment center and flight deck area, offering conveniences like an ice drawer, coffee container, and snack storage.
The cabin features swiveling and trackable seats, ensuring maximum flexibility in the seating arrangement. Additionally, Collins Venue manages the cabin’s entertainment system, offering a Blu-ray media center, SiriusXM radio, and LED lighting. Passengers also have access to multiple monitors, with connectivity options such as Gogo’s air-to-ground system or Cobham Inmarsat SwiftBroadband satcom for international use.
Performance
The CJ4 stands out in its class with exceptional performance. Despite being 3,000 pounds heavier than the CJ3+, it can fly 200 nautical miles farther, making it a capable contender against other light jets like the Phenom 300 and PC-24. The CJ4 has a maximum takeoff weight of 17,110 pounds and can carry 1,000 pounds of payload with full fuel. With a cruising speed of 430 knots at FL450, it offers impressive speed and efficiency, making it a top choice for long-range travel.
With a maximum range of 1,926 nautical miles, the CJ4 can easily handle medium to long-haul flights, with a takeoff distance of 3,410 feet. The aircraft can reach its maximum altitude of FL450 in just 29 minutes, ensuring a smooth and rapid climb. On shorter trips, the CJ4 can reach FL450 in as little as 17 minutes, offering performance that is both fast and efficient.
