It was 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]]. Cessna projected that first delivery would occur in late 2017. The aircraft will have a T-tail empennage, area-rule fuselage contouring, and 30° wing sweep. The engines will be the new [[Snecma Silvercrest]] turbofan, rated at 11,000 lb thrust for takeoff. The aluminum wings will incorporate moderate winglets. Construction will be aluminum for both wing and fuselage.<ref>[http://www.aviationweek.com/Article.aspx?id=/article-xml/awx_05_14_2012_p0-457353.xml Aviation Week & Space Technology, 14 May 2012 edition, ''Cessna Unveils Citation Longitude'']</ref> The fuselage will be 7 inches shorter and 6 inches narrower than the Cessna Citation Columbus design.<ref>{{cite journal|magazine=Aviation Week & Space Technology|title=Course Correction|author=Fred George and Robert Wall|page=18|date=21 May 2012}}</ref> <!-- ==Operational history== --> <!-- ==Variants== --> <!-- ==Units using this aircraft/Operators (choose)== --> ==Specifications (Citation Longitude) == {{Aircraft specs |ref=Aviation Week & Space Technology<!-- for giving the reference for the data --> |prime units?=kts<!-- imp or kts first for US aircraft, and UK aircraft pre-metrification, met(ric) first for all others.
