The Cessna Citation Longitude (Model 800) 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.[2]

Design and development[edit]

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 will have a T-tail empennage and area rule fuselage contouring. The aluminum wings will incorporate moderate winglets. Construction will be aluminum for both wing and fuselage. The cabin will be 7 inches shorter and 6 inches narrower than the Columbus design.[3] Instead of the initially selected Snecma Silvercrest engine,[4] finally used for the Citation Hemisphere, it will be powered by 7,550 pound thrust Honeywell HTF7000 series turbofans. First flight should happen in 2016 with entry into service in 2017.[5]

Its wings and empennages 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.[1]
