Cessna Citation V
Encyclopedia
The Cessna Citation V (Model 560) is a turbofan
-powered small-to-medium sized business jet
built by the Cessna
Aircraft Company in Wichita, Kansas
. The Citation
brand of business jets encompasses several distinct "families" of aircraft, and the Citation V was the basis for one of these families. This family includes the Citation V, the Citation Ultra, the Citation Encore, and the Citation Encore+. Some models are used by the United States military under the designation UC-35, while the OT-47B was procured by the United States Department of Defense
for drug interdiction reconnaissance.
After stretching the Citation I to make the II, Cessna decided to increase the size of the cabin again, stretching the fuselage by another 20 inches (508 mm), resulting in the largest member of the straight-wing family, the Model 560 Citation V. The first engineering prototype flew in August 1987, and certification was granted in December, 1988. The aircraft utilized the T-47A's JT15D5A engines for extra performance. By the time the aircraft was superseded in 1994, 262 had been built.

. The Primus 1000 replaced the standard "round dial" flight instruments with three CRT computer screens, one for each pilot and one center mulifunction display. In 1994, the Ultra was named Flying magazine's "Best Business Jet". The Ultra was produced from 1994-1999. Both the Citation V and Ultra hold 5771 pounds of fuel.
The UC-35A is the United States Army
designation and UC-35C is the United States Marine Corps
designation for the Citation Ultra, which replaced older versions of the C-12 Huron
.
Another version of the Model 560 is the OT-47B "Tracker", five of which were purchased by the Department of Defense for use in drug interdiction reconnaissance operations, based at Maxwell Air Force Base
. The OT-47B utilizes the F-16's
APG-66(V)
fire control radar system and the WF-360TL imaging system. The OT-47Bs have been operated on loan to the Colombian Air Force
and Peruvian Navy
.
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 5,298 pounds, 477 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 soft-landing, trailing link, 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 3.7 feet for better ground tracking and more mannerly, crosswind landing behavior.
The Encore's standard equipment list have been increased and many systems have been upgraded. Bleed air is used to anti-ice the wing 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 330 pounds to 16,630 pounds, enabling it to carry five passengers with full fuel. The additional weight increases 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, allow the Encore to climb faster and cruise higher. Its initial cruise altitude is FL 450.. The Encore was certified in April 2000 with 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.
