Cessna Citation V


The Cessna Citation V is a business jet built by Cessna, stretched from the Citation II.
A prototype flew in August 1987, it was certified on December 9, 1988 and delivered from April 1987, were delivered until 2011.
The upgraded Citation Ultra was announced in September 1993, the Citation Encore upgraded with PW535 turbofans was announced in 1998, before the improved Encore+. Its US Military designation is UC-35.

Design

The Citation V is a slightly stretched Citation II/SP, allowing a standard eight seats, with more powerful Pratt & Whitney Canada JT15D5A turbofans.
The Model 560 variants are the fastest and farthest flying jets with the type certificate of the original Citation 500.
The passenger cabin is long, wide and high with a dropped aisle, has seven windows on each side and accommodates a four-seat club plus three chairs and a closed, belted lavatory.

Development

A preproduction prototype flew in early 1986 and the first engineering prototype made its maiden flight in August 1987. The Citation V was announced at the NBAA convention later that year, US certification was granted on December 9, 1988 and 262 were delivered between April 1987 and mid 1994.
The 1988 Citation V was followed in 1994 by the Citation Ultra with slightly more thrust, the Citation Encore in 2001 then the Citation Encore+ in 2007 through early 2010.
By 2018, Citation V/Ultra were priced at $1.1–1.6 million.

Citation Ultra

The upgraded Citation V Ultra was announced in September 1993 and FAA certification was granted in June 1994. It features more powerful 13.6 kN JT15D5D engines and Honeywell Primus 1000 EFIS avionics. Deliveries amounted to 279.
In 1994, the Ultra was named Flying magazine's "Best Business Jet" and it was produced until 1999. Both the Citation V and Ultra hold 5814 pounds of fuel.

Citation Encore/Encore+

The Citation Ultra Encore was announced at the 1998 NBAA convention, upgraded with new PW535 engines, plus trailing link main undercarriage, more fuel capacity, updated interior and improved systems. Its maximum cruise altitude is FL 450. Deliveries amounted to 168. The Encore was certified in April 2000 with first delivery in late September 2000.
The upgraded Citation Encore+ was offered from 2007 through early 2010. Deliveries amounted to 65. It was certified by the FAA in December 2006.
The Encore+ adds FADEC and Rockwell Collins Pro Line 21 avionics with a center MFD and both side PFDs.
Its weight increased by and, typically equipped, it can haul a payload with full fuel.
It can take off in in ISA conditions, has good hot-and-high performance and climbs directly to FL 450 in 27 min.
It has a range at TAS, the CJ3+ speed but slower than a CJ4.
It can fly with one pilot but most are operated with two.
Fuel burn is for the first hour then, it costs $1,800–1,900 per hour overall with December 2018 fuel prices and $325,000 for fixed expenses.
Light checkups are due every 150 h, basic maintenance at 300 h or 24 months, comprehensive inspections at 1,200 h or 36 months, engine hot section inspections at 2,500 h with 5,000 h overhauls and simple inspections at 10,000 and 12,000 h and at 10,000 and 15,000 landings.
An Encore+ is valued at $3.4–3.8 million in December 2018 and it benefits from Textron Aviation's support.
The CJ3 has better fuel efficiency and runway performance but a shorter cabin, the Learjet 45XR cruises faster and hauls more but needs longer runways and burns more fuel, while the CJ4 has better payload/range but is more expensive.
Softer landing trailing link main landing gear reduced fuel tank capacity to 5,440 pounds, 360 pounds less than the Ultra's, but it has more range. The wheel track was narrowed 3.7 feet for better ground tracking and easier crosswind landing.
The wing leading edge is de-iced by Bleed air. Boundary layer energizers and a stall fence improve stall characteristics. Pressurization is digitally controlled and brake modulation is improved. Redesigned interior fittings and passenger seats provide more seated headroom. Passenger service units provide more even airflow and temperature control.
MTOW increases by 330 pounds to 16,630 pounds, to carry five passengers with full fuel, lengthening takeoff from the 3,180 feet needed by the Ultra. The improved PW535 high altitude thrust allow the Encore to climb faster and cruise higher.

Military designations

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