The Cessna CitationJet/CJ/M2 (also known as the Model 525) are a series of light business jets built by Cessna, and are part of the Citation family. Launched in October 1989, the first flight of the Model 525 was on April 29, 1991. Federal Aviation Administration (FAA) certification was awarded on October 16, 1992, and the first aircraft was delivered on March 30, 1993. The CJ series are powered by two Williams FJ44 engines; the design uses the Citation II's forward fuselage with a new carry-through section wing and a T-tail. The original CitationJet model has been updated into the CJ1/CJ1+/M2 variants; additionally, the CJ1 was stretched into the CJ2/CJ2+ which was built between 2000 and 2016. The design was then further developed into the CJ3/CJ3+, built from December 2004 to present, and finally into the CJ4 which has been built since 2010. By June 2017, 2,000 of all variants had been delivered. In 2021, Cessna announced updated versions of the M2, CJ3, and CJ4 marketed as the Citation Gen2, and in 2024 the company announced plans for the Citation Gen3, which is expected to enter service in 2026.

Development

Like several other members of the Citation family, the CitationJets are certified for single pilot operations.

Development of the CitationJet was prompted by the 1985 discontinuation of the Citation I, a reaction to the increasing price of its Pratt & Whitney JT15D-1 engines, which rendered it uncompetitive with its larger straight wing Citation stablemates. Cessna believed that a substantial market still existed for a light 4-5 passenger jet with low operating costs, docile flying qualities, and the ability to operate from short runways usable by twin piston-engined light aircraft, a formula that had made the Citation I successful. However, that aircraft had been stigmatized for its slower cruise speed than its competitors, which had progressively been addressed in the Citation S/II and Bravo and the Citation V, Ultra and Encore, but at the cost of operating economy. To offer increased speed with reduced purchase and operating costs, Cessna engineers realized that a new, lighter airframe design would be needed, using less expensive and lower-thrust engines. To better compete with newer jets, Cessna also wanted to eliminate the step in the center aisle of the earlier Citations, created by the spar passing through the cabin.

Cessna launched the $2.4 million (equivalent to $ million in ) model 525 CitationJet at the October 1989 NBAA convention in Atlanta, estimating a demand for 1,000 aircraft over ten years. Its first flight was on April 29, 1991, a Federal Aviation Administration (FAA) type certificate was awarded on October 16, 1992, and first delivery happened on March 30, 1993. The aircraft met its initial design goal: its normal cruise speed was 29 kn faster than that of the Citation I, and the newer CitationJet outperformed the older Citation I in all other significant metrics except maximum payload and approach noise, despite having 600 lbf less total engine thrust.

In 2013, the CJ1 was rebranded as the Citation M2, which features extensive cabin upgrades, more thrust, winglets, improved performance, and the Garmin G3000 avionics suite. The M2 became Cessna's entry-level jet when the smaller and less capable Citation Mustang was dropped in May 2017.

Twenty years after its first flight, 1,450 CJs had been produced. As of June 2017, 2,000 of all variants had been delivered, with five million hours flown. In 2017,

In 2021, Cessna announced new versions of the CJ1/M2, CJ3, and CJ4 branded as the Citation Gen2, introducing more advanced avionics, autothrottles, and a variety of cabin and cockpit upgrades. In 2024, the company announced plans for equivalent Citation Gen3 models, which are planned to debut the Garmin G3000 PRIME avionics suite and to introduce Garmin emergency autoland in the CJ/M2 series. The Gen3 models are expected to enter service in 2026, and Cessna expects to offer upgrade kits to add autoland to Gen2 aircraft with autothrottles.

Design

The six-seat CitationJet is a monoplane with a cantilever wing, a retractable tricycle landing gear and a pressurized cabin.

The jet uses the Citation II's forward fuselage, a new carry-through section, a new laminar flow, supercritical wing developed with NASA and Boeing, and a T-tail. Powered by two 1900 lbf Williams FJ44s, the 10,000 lb aircraft has a trailing link undercarriage for smooth landings, and can be flown by a single pilot. Range is 1500 nmi with four passengers and it can cruise at 437 kn.

The CitationJet retains the 58 in inside diameter, circular fuselage cross-section of the Citation I and II, a semi-monocoque construction of conventional aluminum alloys assembled with rivets, fasteners and adhesive bonding. To reduce interference drag, a large fairing encases the low wing center section, and the engines are mounted high on the tail. Composite materials save weight in non-load-bearing components including fairings and the nose radome. The cockpit features EFIS avionics; fuselage length is reduced 11 inches (27 cm) compared to the Citation I, and cabin length is reduced by 1 ft, but with a lowered center aisle for increased cabin height. The cockpit side windows are slightly smaller than those on earlier Citations to lessen interior temperature differences between the cockpit and the main cabin.

Wing structure is a conventional ladder with chord-wise ribs over front and rear spars, and an aft sub spar to support the landing gear. The NASA high-speed 0213 airfoil sustains natural laminar flow over 30% of the upper surface for 10-15% better lift-to-drag ratio than the larger NACA 23000-series wing of the Citation I. To maintain the wing's laminar-flow qualities and reduce weight, icing protection is provided by ducted bleed air rather than the deicing boots or fluid deicing systems used on earlier Citations.

Its FJ44 engine has a 16:1 overall pressure ratio and a 2.58:1 bypass ratio. Early CitationJet models have a novel design feature to reduce weight: rather than conventional thrust reversers, the aircraft are equipped with thrust attenuator paddles that pivot from the rear fuselage, similar to those used on the Cessna T-37 Tweet military trainer.

Launched in September 2011, it is based on the then out-of-production CJ1 variant and features a new cabin layout and a more efficient FJ44 version. The initial M2 prototype first flew on 9 March 2012; it was not a conforming airframe but was testing the Garmin G3000 avionics and Williams FJ44-1AP-21 turbofans while another aircraft was expected to join the certification program in May 2012 to be used for aerodynamics testing. Compared to the CJ1+, it climbs more quickly, offers a more comfortable cabin and is faster by 22 kn at FL 410. The wing is 4 in wider due to small winglets. The FJ44-1AP-21s TBO can reach 5,000 h and the aircraft burns 740 lb per hour at 392 kn TAS, FL 400, ISA+3C conditions and at a weight of 9,646 lb. At high-speed cruise, it can fly one pilot and four passengers over 1,150 nmi in 2 h 49 min. It climbs to FL 410 in 24 min, 27% faster than its closest competitor, where it is 53 kn faster than the Embraer Phenom 100E. With 150 produced since introduction in 2013, it became Cessna's entry-level jet after the Citation Mustang ended production in May 2017. The 250th M2 was delivered on June 15, 2020. In 2023, its equipped price was $6.15M.

;Citation M2 Gen2 :An upgraded model of the M2 was unveiled in 2021 as the Citation M2 Gen2. The M2 Gen2 differs from the original M2 in that it is fitted with a restyled premium interior with wireless chargers as well as USB-A and USB-C ports. Cargo space was increased to allow an extra 50 lb of luggage to be carried, and the copilot position was given 3 in of added legroom. The M2 Gen2 was certified in 2022, with deliveries beginning shortly thereafter. In 2023, Cessna announced that a Garmin autothrottle would be available for the M2 Gen2 starting in mid-2025.
