Cessna Citation Encore C560

The Cessna Citation Encore is a twin-engined corporate jet aircraft produced by the American manufacturer Cessna Aircraft Company. It is a development of the Cessna 550 Citation II.

Citation Encore Design & Development

The Citation V, Citation Ultra, and Ultra Encore are the largest straight-wing members of Cessna’s highly successful Citation family. Cessna publicly announced it was developing a stretched development of the Citation II at the annual NBAA convention in New Orleans in 1987. Earlier in August that year the first engineering prototype Model 560 Citation V had completed the type’s maiden flight. A preproduction prototype flew in early 1986, while US certification was granted on December 9, 1988. Deliveries began the following April.

The Citation V was based on the Citation II/SP, but differences over the smaller jet include more powerful Pratt & Whitney Canada JT15D5A turbofans and a slight fuselage stretch, allowing seating in a standard configuration for eight passengers. The Citation V proved quite popular, with 262 built through to mid-1994 before production switched to the modernized Ultra.

Cessna announced the development of the upgraded Citation V Ultra in September 1993. FAA certification was granted in June 1994, allowing for deliveries of production aircraft to commence soon after. Compared with the Citation V, the Ultra features more powerful 13.6 kN (3045 lb) Pratt & Whitney Canada JT15D5D engines and Honeywell Primus 1000 EFIS avionics with three CRT displays (two primary flight displays and one multifunction display).

The Citation Ultra Encore is a new development announced at the 1998 NBAA convention. Compared with the Ultra the Encore introduces new Pratt & Whitney Canada PW535 engines, plus trailing link main undercarriage, more fuel payload, updated interior and improved systems. The Ultra’s Honeywell Primus 1000 EFIS avionics suite is retained.

In 1993, Cessna decided to update the Citation V design and announced the Citation Ultra.

Upgraded Citation Encore

Five years later, in 1998, the Model 560 was upgraded again as the Citation Encore, with Pratt & Whitney Canada PW535A engines and a decrease in fuel capacity to 5,440 pounds, 360 pounds less than the Ultra’s, but it has more range than the Ultra-1,700 nmi with NBAA IFR reserves. The reduction in fuel tank size allowed Cessna to fit the Encore with a soft landing, trailing link, and main landing gear, a welcome change for pilots who griped about the notorious kerplunk touchdown characteristics of the stiff-legged earlier Citations aircraft. In addition, the wheel track has been narrowed to 3.7 feet for better ground tracking and more mannerly crosswind landing behavior.

Standard Equipment

The Encore’s standard equipment list has been increased and many systems have been upgraded. Bleed air is used to anti-ice the wing's leading edge, and several boundary layer energizers, plus a stall fence, have been added to the wing to improve stall characteristics. A digital pressurization controller reduces pilot workload and an improved wheel brake system offers better modulation. Redesigned interior fittings and passenger seats provide more seated headroom. New passenger service units provide more even airflow and temperature control. The Encore’s MTOW is bumped from 330 pounds to 16,630 pounds, enabling it to carry five passengers with full fuel. The additional weight increases the takeoff field length to 3,561 feet, compared with 3,180 feet for the Ultra. The much improved high-altitude thrust output of the PW535 engines, however, allows the Encore to climb faster and cruise higher. Its maximum cruise altitude is FL 450. The Encore was certified in April 2000 with the first delivery in late September 2000. The next upgrade was the Citation Encore+, with the addition of FADEC-controlled PW535B engines and Rockwell-Collins Pro Line 21 avionics suite. The Encore+ was certified by the FAA in December 2006, with deliveries of production aircraft expected in the first quarter of 2007.

The UC-35B is the Army designation and UC-35D is the Marine Corps designation for the Citation Encore.

Specifications

The perfect combination of range, speed, and comfort in a light cabin jet, this jet offers midsize range and modern flight technology.

The Citation Encore+/Encore uses modern technologies to enhance the proven design of one of the best-selling light cabin business jets of all time, the Citation V Ultra. The Encore’s increased performance allows for faster climbs to altitude – translating into a more comfortable ride – as well as additional range. The cabin offers many larger jet amenities such as a full refreshment center and a fully-enclosed aft lavatory.
