The Cessna Aircraft Company in Wichita, Kansas, had developed a line of small-to-medium turbofan-powered business jet. This was known in the history of aviation as the Citation family of aircrafts, and this alone encompasses a huge number of models. The Citation V family, specifically, includes the Citation Ultra, the Citation Encore, and the Citation Encore +. Like the Citation II, the Citation V was also used by the United States Military under the designation UC-35.

From the FanJet 500 prototype, to developing the Citation I and Citation II, Cessna followed the success of their previous aircrafts by using the same philosophy they have with these models. The major improvement that was going to take place yet again was the need for larger seating capacity and a more powerful engine for faster speeds and longer flight ranges.

With the Citation V, or the Model 560, the company had increased the cabin size by stretching the fuselage another 20 inches, “resulting in the largest member of the straight wing family.” * The Model 560 or Citation V’s prototype flew in August 1987, and was certified for flight a year thereafter, in December 1988. The engine that was adopted for this model was Model 552 or T47-A’s JT15D5A engine, the same model that was also used by the United States Navy. 262 aircrafts had been made by the time this model ceased in 1994.

The Citation V had a number of models under its wing. The Citation Ultra was developed in 1993, by updating the V’s design in terms of engine power. The latest JT15D-5D version was incorporated into the model, and the standard cockpit was updated to the Honeywell Primus 1000 EFIS glass cockpit. This replaced the standard “round dial” instruments with three CRT computer screens, one for each pilot and one for multi-function center display. In 1994, Flying magazine named the Ultra the best business jet, and it was in production from that year until 1999.

The same model, Citation Ultra, was also under designation for the United States Army (UC-35A), and the United States Marine Corps (UC-35C). These models replaced the C-12 Huron, which was manufactured by Cessna’s leading competitor, Beechcraft.

By 1998, five years after the Ultra was produced, the Model 560 was again upgraded as the Citation Encore and Encore+. Pratt and Whitney Canada PW535A engines were used for the Citation Encore, and the fuel capacity was also increased. The landing gear was also improved in this line. It was certified by April of 2000 and was delivered for flight by September of the same year. The Encore+ on the other hand, was certified by December of 2006 and was in distribution by early 2007. The FADEC-controlled PW535B engines and Rockwell Collins Pro Line 21 Avionics Suite were among the developments in this line. FADEC is a system consisting of fully digital controls for the aircraft engine performance. It is composed of a digital computer which is also called an engine control unit, and is used for both piston engines and jet engines.
The Citation Encore+ was also used for the Army and Marine Corps in the same way that the Encore was. The UC-35B and UC35-D were the designations for each, respectively.

According to reviews, the Citation V “has a fine blend of cabin comfort, performance, and reliability. It is a good choice for short trips.” ** This is probably the most spacious of all Cessna planes, and the size of the aircraft is almost always the deciding factor in purchasing it. Compared to the Citation Bravo, which was the benchmark for a spacious interior at that time, the designers of this plane did take advantage of the extra cabin space. They installed “extra-wide seats that reclined 60 degrees and rotated a full 360 degrees.”** Not only roomy inside, this aircraft also has external baggage capacity. It also adopted new soundproofing techniques, and even sports triple glazed windows. Hence, it is “one of the quietest planes available.”** It is a favorite not only by its passengers but of the pilots who fly it as well. The cockpit visibility is unmatched by any other private jet in its class.

Indeed, what the Citation V offers is really performance, comfort, and reliability, which is what the company itself is also known for.
