The Cessna Citation Sovereign (Model 680) is an American {{cvt|3,200|nmi|km}} range business jet developed by Cessna, part of the Cessna Citation family. Announced at the 1998 NBAA convention, it made its maiden flight in February 2002, certification was awarded on June 2, 2004, and deliveries began in late September. The improved Sovereign+ was announced at the October 2012 NBAA for a first flight in April 2012 and deliveries in December, with winglets, improved engines and flight deck. The Citation Excel fuselage was stretched and joined with a large, clean-sheet 16.3 °, {{cvt|516|sqft}} wing and two {{cvt|5,900|lbf|kN}} PW300 engines for a {{cvt|30,800|lb}} MTOW. DevelopmentIn the late 1990s, Cessna wanted to fill a gap in its midsize line-up as demand for its Cessna Citation III/VI/VII waned, with greater cabin comfort, performance and utility than its concurrence but with Citation reliability, a high aerodynamic lift wing for runway performance, and near transcontinental flight range to compete with the Hawker 800, a thrust-to-weight ratio to rival the climb performance of the Learjet 60.[3] It was announced at the 1998 NBAA convention, it made its maiden flight in February 2002 and deliveries began in late September 2004.[2] FAA certification was awarded on June 2, 2004.[3] EASA certification came on 31 March 2005.[4] The improved Sovereign+ was announced at the October 2012 NBAA, it rolled out in early March 2013, first flew in April, and began deliveries on December 23 after certification, at a time when the Sovereign fleet reached 349 and had flew 802,000 hours. Winglets were for more range of {{cvt|150|to|3,000|nmi|km}}, new PW306D engines with autothrottles provides {{cvt|5,852|lbf|kN}} of thrust for a {{cvt|458|knots|km/h}} top speed and a FL450 direct climb, full fuel payload was increased and the Garmin G5000 replaces the avionics.[5]DesignThe Citation Excel fuselage was stretched for a {{cvt|6.6|ft}} longer cabin and joined with a large, clean-sheet {{cvt|515.9|sqft}} wing with large trailing edge flaps for runway performance, with a relatively high critical Mach number for efficient {{cvt|445|knots|km/h}} TAS cruise. It is powered by {{cvt|5,770|lbf|kN}} Pratt & Whitney Canada PW306C engines, derated from the Gulfstream G200 or Do 328JET, and uses Honeywell Primus Epic glass cockpit avionics with four LCD screens. The cabin maintains a {{cvt|7,200|ft}} altitude with the {{cvt|9.3|psi|bar}} pressurization and typically comprise double-club seating for eight, two more than the Gulfstream G150, plus a side facing seat, and can accommodate up to 11.[3] It can carry a full fuel payload of {{cvt|1,000|-|1,200|lb|kg}} and can fly {{cvt|2,840|nmi|km}} at a block speed of {{cvt|406|knots|km/h}}. It can takeoff in {{cvt|3,640|ft}} and climb to FL410 in 19 min and to FL430 in 26 min. It travels {{cvt|400|nmi|km}} in the first hour while burning {{cvt|2,000|lb|kg}} at FL410, {{cvt|420|nmi|km}} the second hour with {{cvt|1,550|and|1,400|lb|kg}} the third hour at FL430.[3] At a weight of {{cvt|10,505|kg|lb}} and ISA -5°C, it burns 653 kg (1,440 lb) per hour at Mach 0.778 / {{cvt|441|knots|km/h}} or {{cvt|454|kg|lb}}/h at a long-range cruise speed of Mach 0.634 / {{cvt|360|knots|km/h}}.[2] OperationsBasic maintenance is due at 400 hr or every 12 months and dispatch reliability is over 99%. The Learjet 60 cruises faster with less fuel but its cabin is smaller, the slower Hawker 900XP has {{cvt|100|mi|km}} less range and a wider but shorter cabin like the Gulfstream G150 which has more range, speed and fuel economy. In 2017, the Sovereign were sold from $5 to $9 million for early 2004 models to 2013 aircraft.[6] In 2013, two-thirds of the fleet was in the U.S. with NetJets as its largest operator with 44.
