Cessna Citation Longitude

The Cessna Citation Longitude (Model 700^[3]) is a super mid-size business jet project, part of the Cessna Citation family, announced at the May 2012 EBACE and scheduled for introduction in 2017.^[4] It made its first flight on October 8, 2016^[1]

Design

The project is perceived as the follow-on development to the now-canceled Cessna Citation Columbus. Its fuselage cross-section (83.25 inch circular section) is the same as the Cessna Citation Latitude. The aircraft has a T-tail empennage and area rule fuselage contouring. The aluminum wings incorporate moderate winglets. Construction is aluminum for both wing and fuselage. The cabin is 7 inches shorter and 6 inches narrower than the Columbus design.^[5]

Initially, the Snecma Silvercrest engine was selected.^[6] Finally it is powered by Honeywell HTF7000 turbofans.^[7] The Silvercrest is used for the larger Citation Hemisphere.

Its wings and empennage are similar to the Hawker 4000 with winglets leading to a 5.3 ft. larger wingspan. The moderately super-critical wing have a quarter-chord sweep of 26.8° for its inner section and 28.6° for the outer section. The six-passenger Latitude fuselage has been reinforced and stretched by another row of seats to accommodate eight people in double club. The manufacturer has not announced the final design weights (as of May 2016); BCA estimates a 24,000–25,000 lb. basic operating weight. Cabin height is 6.0 ft., width is 6 ft. 5 in., floor width is 4 ft. 1 in and cabin length is 25 ft.^[2]

Development

The first flight-test aircraft completed its first flight in October 2016. The second flew in November, and in March 2017 the third, used to develop avionics and systems and to collect flight simulator data before two others will join the test program. The two aircraft completed 125 flights for more than 250 hours as production of the aircraft commenced at Textron Aviation's Wichita, Kansas facility.^[8]

Less than eight months after the first flight and after more than 200 missions for nearly 400 hours, on track for certification later in 2017, the fourth prototype joined the flight-test program on May 6, fully outfitted for interior, environmental control system, pressurization and cabin technologies evaluation.^[9] The first production unit was rolled out on June 13, 2017 as the four test aircraft have flown 550 hours and a fifth aircraft will join in summer 2017.^[10]
