TheCessna Citation Sovereign (Model 680) is an Americanbusiness jet developed byCessna, part of theCessna Citation family.Announced at the 1998NBAA convention, the Model 680 made itsmaiden flight in February2002, certification was awarded on June 2, 2004, and deliveries began in late September.TheCitation Excel fuselage was stretched and joined with an all-new, larger wing and more powerfulPratt & Whitney Canada PW306C engines for increasedmaximum takeoff weight and a 3,200 nmi (5,900 km) range.The improvedSovereign+ was announced at the October 2012 NBAA for a first flight in April 2013 and deliveries in December, with addedwinglets and an improved flight deck and engines.
In the late 1990s, Cessna wanted to fill a gap in its midsize line-up as demand for itsCessna Citation III/VI/VII waned, with greater cabin comfort, performance and utility with Citation reliability, good runway performance, neartranscontinental flight range to compete with theHawker 800, and athrust-to-weight ratio to rival the climb performance of theLearjet 60.[2]
The Citation Sovereign was announced at the 1998NBAA convention, it made itsmaiden flight in February2002, and deliveries began in late September 2004.[3]FAA certification was awarded on June 2, 2004.[4]EASA certification came on 31 March 2005.[5]
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 flown 802,000 hours.Winglets were for a range of 150 to 3,000 nmi (280 to 5,560 km), newPW306D engines withautothrottles provided 5,852 lbf (26.03 kN) of thrust for a 458 kn (848 km/h) top speed and a FL450 direct climb, full fuel payload was increased and theGarmin G5000 replaced the avionics.[6]
In March 2021, Cessna announced that Sovereign+ production had ended to reduce market overlap between it and the similarly capable but more recently developedCitation Latitude andCitation Longitude. 349 Sovereign and 94 Sovereign+ aircraft were produced.[1][7]
TheCitation Excel fuselage was stretched for a 6.6 ft (2.0 m) longer cabin and joined with a large, newly designed 515.9 sq ft (47.93 m2) wing with large trailing edgeflaps for good runway performance, 16.3°wing sweep and a relatively highcritical Mach number for efficient 445 kn (824 km/h)TAS cruise.It is powered by 5,770 lbf (25.7 kN)Pratt & Whitney Canada PW306C engines, derated from theGulfstream G200 or Do328JET, and usesHoneywell Primus Epic glass cockpit avionics with four LCD screens.The cabin maintains a 7,200 ft (2,200 m) altitude with the 9.3 psi (0.64 bar) pressurization and typically comprises double-club seating for eight, two more than theGulfstream G150, plus a side facing seat, and can accommodate up to 11.[2]
It can carry a full fuel payload of 1,000–1,200 lb (450–540 kg) and can fly 2,840 nmi (5,260 km) at a block speed of 406 kn (752 km/h).It can take off at 3,640 ft (1,110 m) and climb to FL410 in 19 min and to FL430 in 26 min.It travels 400 nmi (740 km) in the first hour while burning 2,000 lb (910 kg) at FL410, 420 nmi (780 km) the second hour with 1,550 and 1,400 lb (700 and 640 kg) the third hour at FL430.[2]At a weight of 10,505 kg (23,160 lb) and ISA -5 °C, it burns 653 kg (1,440 lb) per hour at Mach 0.778 / 441 kn (817 km/h) or 454 kg (1,001 lb)/h at a long-range cruise speed of Mach 0.634 / 360 kn (670 km/h).[3]
Basic maintenance is due at 400 hr or every 12 months and dispatch reliability is over 99%.TheLearjet 60 cruises faster with less fuel but its cabin is smaller, the slowerHawker 900XP has 100 mi (160 km) less range and a wider but shorter cabinlike theGulfstream 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.[2]
In 2013, two-thirds of the fleet was in the U.S. withNetJets as its largest operator with 44.In Americas, 20 were in Brazil, 12 in Canada and eight in Mexico. In Europe, ten were in U.K., nine in Germany, three in Czechia and in Austria, two in the Netherlands. In Africa, eight were in Egypt, four in South Africa and one in Morocco. In Asia, eight were in Turkey, five in China, three in Australia and one in Jordan.Most corporate operators fly the aircraft 350- to 400-hr. per year, less for individuals while fractional ownership and air charter aircraft may be used 1,200 hr. per year.[8]
