The Cessna Citation Longitude is a business jet produced by Cessna, part of the Cessna Citation family. It remains the largest business jet by Cessna.
Announced at the May 2012 EBACE, the Model 700 made its first flight on October 8, 2016, with certification obtained in September 2019.
The aluminum airframe has the fuselage cross-section of the Citation Latitude, stretched by a seat row.
Powered by Honeywell HTF7000 turbofans, it has a new ~28° swept wing and a T-tail for a {{cvt|3,500|nmi|km}} range.
Design
File:EBACE 2023, Le Grand-Saconnex (EB237582) (cropped).jpg
The project is perceived as the follow-on development to the now-canceled Cessna Citation Columbus. Its fuselage cross-section ({{convert|83.25|in|cm|adj=on|disp=sqbr}} 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 {{convert|7|in|cm}} shorter and {{convert|6|in|cm}} narrower than the Columbus design.{{cite web |work= Aviation Week & Space Technology |title= Cessna Unveils Citation Longitude |author= Fred George |date= 14 May 2012 |url= http://aviationweek.com/business-aviation/cessna-unveils-citation-longitude}}
Initially, the Snecma Silvercrest engine was selected to power the aircraft,{{cite web |url= http://cessna.txtav.com/~/media/Files/citation/longitude/Longitude%20SD%202012.ashx |title= Citation Latitude Preliminary Specification & Description |publisher= Cessna |date= February 2012 |access-date= 2016-04-29 |archive-url= https://web.archive.org/web/20160306145852/http://cessna.txtav.com/~/media/Files/citation/longitude/Longitude%20SD%202012.ashx |archive-date= 2016-03-06 |url-status= dead }}
however the production model is powered by Honeywell HTF7000 turbofans.{{cite press release |url= http://txtav.com/en/newsroom/2015/11/cessna-showcases-new-citation-longitude-at-nbaa-2015 |title= Cessna showcases new Citation Longitude at NBAA 2015; announces large cabin Citation Hemisphere |date= 16 November 2015 |publisher= Cessna}} The Silvercrest was planned for the larger Citation Hemisphere, but Textron suspended its development in July 2019 as the turbofan did not meet objectives.{{cite news |url= https://www.flightglobal.com/news/articles/textron-suspends-cessna-hemisphere-programme-459720/ |title= Textron suspends Cessna Hemisphere programme |date= 17 July 2019 |author= Michael Gubisch |work= Flightglobal}}
Its wings and empennage are similar to the Hawker 4000 with winglets leading to a {{convert|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 {{convert|24000|-|25000|lb|-2|adj=on}} basic operating weight. Cabin height is {{convert|6.0|ft|abbr=on}}, width is {{convert|6|ft|5|in|abbr=on}}, floor width is {{convert|4|ft|1|in|abbr=on}} and cabin length is {{convert|25|ft|abbr=on}}.{{cite web|url=http://aviationweek.com/business-aviation/cessna-citation-longitude-about-take|title=Cessna Citation Longitude About to Take Off|date=7 March 2016|author=Fred George|publisher=Business & Commercial Aviation}}
After a takeoff at {{cvt|31150|lb}}, {{cvt|8350|lb}} below the {{cvt|39500|lb}} MTOW, the climb rate is {{cvt|2,550|ft/min|m/s}} at FL200.

The first flight-test aircraft completed its first flight on October 8, 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.{{cite news |url= http://www.avweb.com/avwebflash/news/Textron-Starts-Longitude-Production-228673-1.html |title= Textron Starts Longitude Production |last= Grady |first= Mary |work= AVweb |date= 20 March 2017}}
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.{{cite news |url= https://www.ainonline.com/aviation-news/business-aviation/2017-05-09/textrons-fourth-longitude-takes-skies |title= Textron's Fourth Longitude Takes To Skies |author= Kerry Lynch |date= May 9, 2017 |work= Aviation International News}}
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.{{cite press release |url= http://txtav.com/en/newsroom/2017/06/textron-aviation-rolls-out-first-production-cessna-citation-longitude |title= Textron Aviation rolls out first production Cessna Citation Longitude, introduces advanced manufacturing technologies to super-midsize market |date= June 13, 2017 |publisher= Cessna}}
In October 2017, test aircraft have completed more than 1,200 flight hours over 600 flights, for a certification expected by the end of 2017 or in early 2018.{{cite news |url= http://aviationweek.com/nbaa-2017/cessna-latitude-billion-dollar-business |title= Cessna Latitude 'A Billion Dollar Business' |date= Oct 11, 2017 |author= Molly McMillin |work= Aviation Week Network}}
In February 2018, as the five aircraft accumulated over 1,000 flights and 2,000 hours, US approval and customer deliveries of the US$27 million jet were expected before the end of the second quarter before European validation six months later.{{cite news |url= https://www.flightglobal.com/news/articles/picture-textron-aviation-closes-in-on-citation-long-446233/ |title= Textron Aviation closes in on Citation Longitude certification |date= 27 Feb 2018 |author= Kate Sarsfield |work= Flightglobal}}
After 3,000 hours on five aircraft, flight testing will conclude by early June 2018, and 200,000 pages of documentation will be completed after a month.{{cite news |url= https://www.ainonline.com/aviation-news/business-aviation/2018-05-28/citation-longitude-poised-complete-flight-test-campaign |title= Citation Longitude Poised to Complete Flight-test Campaign |author= Ian Sheppard |date= May 28, 2018 |work= Aviation International News}}
As testing has doubled for certification, expanding related documentation, it is expected in the third quarter of 2018 with deliveries from late in this quarter or early in the fourth, less than a year after originally planned.{{cite news |url= https://www.ainonline.com/aviation-news/business-aviation/2018-07-18/tackling-new-faa-process-textron-eyes-3q-longitude-nod |title= Tackling New FAA Process, Textron Eyes 3Q Longitude Nod |author= Kerry Lynch |date= July 18, 2018 |work= AIN online}}
It received a partial exemption for fuel tank flammability requirements applicable through January 2020 to keep its third-quarter approval goal, but a compliance plan had to be submitted by October 1, 2018.{{cite news |url= https://www.ainonline.com/aviation-news/business-aviation/2018-08-28/temporary-exemption-clears-hurdle-longitude-faa-nod |title= Temporary Exemption Clears Hurdle for Longitude FAA Nod |author= Kerry Lynch |date= August 28, 2018 |work= AIN online}}

After 4,050 hours in 1,650 test flights, the Longitude received a provisional FAA type certification on December 20, allowing deliveries in early 2019.{{cite press release |url= https://txtav.com/en/newsroom/2018/12/cessna-citation-longitude-achieves-provisional-type-certification |title= Cessna Citation Longitude achieves provisional type certification |date= December 20, 2018 |publisher= Textron Aviation}}
The fuel tank flammability requirements were addressed on December 5, with airplanes to be delivered having the definitive installation but limiting it for high elevation airport or RVSM operations, and restricting maintenance.{{cite news |url= https://www.ainonline.com/aviation-news/business-aviation/2018-12-20/textron-gets-provisional-type-certificate-longitude |title= Textron Gets Provisional Type Certificate for Longitude |author= Jerry Siebenmark |date= December 20, 2018 |work= AIN online}}
The provisional type certification allowed to begin customer training flights and Textron expects certification in February 2019, while deliveries to NetJets should begin in the third quarter.{{cite news |url= https://www.flightglobal.com/news/articles/cessna-eyes-longitude-approval-despite-us-governmen-455295/ |title= Cessna eyes Longitude approval, despite US government shutdown |date= 25 Jan 2019 |author= Kate Sarsfield |work= Flightglobal}}
