24-483: The project is perceived as the follow-on development to the now-canceled Cessna Citation Columbus . Its fuselage cross-section (83.25-inch [211.5 cm] 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

48-526: A 24,000–25,000-pound (10,900–11,300 kg) basic operating weight . Cabin height is 6.0 ft (1.8 m), width is 6 ft 5 in (1.96 m), floor width is 4 ft 1 in (1.24 m) and cabin length is 25 ft (7.6 m). After a takeoff at 31,150 lb (14,130 kg), 8,350 lb (3,790 kg) below the 39,500 lb (17,900 kg) MTOW, the climb rate is 2,550 ft/min (13.0 m/s) at FL200. At its Mach 0.83, 473 kn (876 km/h) TAS max cruise, fuel flow per side

72-500: A certification expected by the end of 2017 or in early 2018. 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. 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

96-510: A month. 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. 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. On October 15, 2018, fractional operator NetJets announced

120-523: A results of the cancellation. The SEC-filed documents indicate that Cessna spent approximately US$ 50 million on tooling, facilities and other costs for the project. Most of these costs are unrecoverable and cannot be used for other projects. Pratt & Whitney Canada immediately stopped the PW810 engine program, but continued the PW800 series. On July 11, 2009, Cessna announced that it would return US$ 10M to

144-426: A target range of 4,000 nmi (7,408 km) with 8 passengers. The cockpit would have featured a synthetic vision system , autothrottles , optional head-up display and Collins' MultiScan weather radar with optional windshear prediction. Cessna was going to invest $ 780 million into the development including a new plant, major suppliers were Pratt & Whitney Canada for the engines; Rockwell Collins for

168-623: Is 7 inches (18 cm) shorter and 6 inches (15 cm) narrower than the Columbus design. Initially, the Snecma Silvercrest engine was selected to power the aircraft, however the production model is powered by Honeywell HTF7000 turbofans. The Silvercrest was planned for the larger Citation Hemisphere , but Textron suspended its development in July 2019 as the turbofan did not meet objectives. Its wings and empennage are similar to

192-689: Is 860–880 lb (390–400 kg) per hour at FL430 and ISA -4. A M0.79 long range cruise would burn 1,820 lb (830 kg) per hour at a 451 kn (835 km/h) true airspeed for a 38,001 lb (17,237 kg) aircraft, and 2,122 lb (963 kg) per hour at its M0.84 MMO - 477 kn (883 km/h) TAS. Announced at the May 2012 EBACE and scheduled for introduction in 2017. The first flight-test aircraft completed its first flight on October 8, 2016. The second flew in November, and in March 2017

216-473: Is common below 7,000 lbf (31 kN) but rare in its 10,000–12,000 lbf (44–53 kN) range, and the pressure losses complexity at the final centrifugal stage made it slow to respond to commands in high altitude tests. This made Dassault cancel its Silvercrest-powered Falcon 5X , but the Hemisphere business case depends on it as it could lead to the best fuel efficiency in the segment. Textron

240-478: Is confident Safran can resolve the problems before the 2019 first flight . In April 2018, development was suspended to see how Safran manage the Silvercrest problems before a decision on its continuation is made, or to defer it or to switch to another engine. In May 2018, Safran announced it had launched a high-pressure compressor redesign for a go-ahead decision by the middle of 2019, after testing, shelving

264-496: The Hawker 4000 with winglets leading to a 5.3 feet (1.6 m) 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
