Airbus initially rejected Boeing's claim that the Boeing 787 Dreamliner would be a serious threat to the Airbus A330, stating that the 787 was just a reaction to the A330 and that no response was needed. [89] Zodiac Aerospace encountered production difficulties with business class seats in their Texas and California factories. It holds crew, passengers, and cargo.In single-engine aircraft, it will usually contain an engine, as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. Cross section (or airfoil) 6. [139] The higher-thrust version will have some modifications to the fan module—it will be the same diameter but will run slightly faster and have a new fan blade design—and run at increased temperatures allowed by new materials technologies from Rolls-Royce's research.[140]. [57] In June 2009, the National Assembly for Wales announced provision of a £28 million grant to provide a training centre, production jobs and money toward the new production centre. Horizontal position relative to the fuselage 5. In May 2009, GE said that if it were to reach a deal with Airbus to offer the current 787-optimised GEnx for the A350, it would only power the -800 and -900 variants. Hoop frame at approximately 0.55 m (21.5 in) pitch support integrally machined panels having closely pitched longitudinal stringers. "[75] It flew for 4 hours, reaching Mach .8 at 25,000 feet after retracting the landing gear and starting a 2,500 h flight test campaign. Avionics are a further development of the integrated modular avionics (IMA) concept found on the A380. Average daily usage by first customers was 11.4 hours with flights averaging 5.2 hours, which are under the aircraft's capabilities and reflect both short flights within the schedules of Qatar Airways and Vietnam Airlines, as well as flight-crew proficiency training that is typical of early use and is accomplished on short-haul flights. In September 2006 the airline signed a memorandum of understanding with General Electric (GE) to launch the GEnx-1A-72 engine for the aircraft. [9] A350 programme chief Didier Evrard stressed that delays only affected the A350-900 while the -800 and -1000 schedules remained unchanged. [103] Design freeze for the A350-900 was achieved in December 2008. Although these concepts show great promise they still require a substantial amount of research and development to achieve their potential. [152], The three main variants of the A350 were launched in 2006, with entry into service planned for 2013. The first A350 design proposed by Airbus in 2004, in response to the Boeing 787 Dreamliner, would have been a development of the A330 with composite wings and new engines. [244], In November 2019, General Electric was offering an advanced GEnx-1 variant with a bleed air system and improvements from the GE9X, developed for the delayed Boeing 777X, to power a proposed A350neo from the mid-2020s. [71] The Airbus A350 XWB is a family of long-range, wide-body airliners developed by Airbus. In 2005, GE was the launch engine of the original A350, aiming for 2010 deliveries, while Rolls-Royce offered its Trent 1700. by markus steindl. 33 374 5. Used by the social networking service, LinkedIn, for tracking the use of embedded services. [156] Because of the A350-900's fuel consumption of 5.8 tonnes/hour, it needs an additional 24 tonnes of fuel to fly 19 hours instead of the standard 15 hours: the increased MTOW and lower payloads will enable the larger fuel capacity. What do Embraer deliveries promise to pilots? Google DoubleClick – Opt out – Privacy policy [44], GE stated it would not offer the GP7000 engine on the aircraft, and that previous contracts for the GEnx on the original A350 did not apply to the XWB. The redesigned composite fuselage allows for higher cabin pressure and humidity, and lower maintenance costs. The longest operated sector was Qatar Airways' Adelaide–Doha at 13.8 hours for 6,120 nmi (11,334 km). [87] Recently for large transport airplanes (airbuses) multideck fuselages are applied. [76] Costs for developing the aircraft were estimated at €11 billion (US$15 billion or £9.5 billion) in June 2013. By eliminating corners, the flow will not separate at moderate angles of attack or sideslip 2. [78] On 15 October 2014, EASA approved the A350-900 for ETOPS 370, allowing it to fly more than six hours on one engine and making it the first airliner to be approved for "ETOPS Beyond 180 minutes" before entry into service. These frames are then joined with lightweight longitudinal elements called stringers. It doesnot correspond to any user ID in the web application and does not store any personally identifiable information. [59] Production of the first fuselage barrel began in late 2010 at its production plant in Illescas, Spain. Fuselages can have some baseline designs, which are shown on fig. The cookie is set by Google. [74], The A350's maiden flight took place on 14 June 2013 from the Toulouse–Blagnac Airport. They help us know which pages are the most and least popular and see how visitors move around the site. The A350-900 has four-wheel bogies in a 4.1 m (13 ft) long bay. cookielawinfo-checkbox-functional-cookies, This cookie is set by GDPR Cookie Consent plugin.

[79] Later that month Airbus received regulatory approval for a Common Type Rating for pilot training between the A350 XWB and A330. 2 2. • The wetted area of a high wing is not much less than its gross surface area since only the lower surface of the carry-through structure is covered by the fuselage. [60] Construction of the first A350-900 centre wingbox was set to start in August 2010. "[18][19] As major airlines such as Qantas and Singapore Airlines selected the 787 over the A350, Humbert tasked an engineering team to produce new alternative designs. [24][115] Overall, the A350 gives passengers more headroom, larger overhead storage space, and wider panoramic windows than current Airbus models. B for Bruce. [94] The wing twist is being changed for the wider, optimised spanload pressure distribution, and they will be used for the Singapore Airlines A350-900ULR in 2018 before spreading to other variants. [133] The final configuration of wing and winglet was achieved for the "Maturity Gate 5" on 17 December 2008. Cross-Section Design It is often reasonable to start the fuselage layout with a specification of the cross-section: its shape and dimensions. Used by Facebook to deliver a series of advertisement products such as real time bidding from third party advertisers. [173] It made its first flight on 23 April 2018. In December 2006, Rolls-Royce was selected for the A350 XWB launch engine. It had a common fuselage cross-section with the A330 and also a new horizontal stabiliser. [171] Non-stop flights could last more than 20 hours. It is interesting that if any of the floors were removed the fuselage would break apart when pressurized. This was then ingrained in Boeing thinking, as it was slightly less expensive to design a double-lobe fuselage for the required space and yet to keep the structure weight down. [86], In service, problems occurred in three areas. [195] In early 2020, Airbus was proposing an A350F before a potential launch. by Kip. After the Boeing 787-10 launch at the 2013 Paris Air Show, Airbus discussed with airlines a possible A350-900 Regional with a reduced MTOW of 250 t (550,000 lb). [182], At the 2015 Dubai Air Show, John Leahy noted the demand of the Middle Eastern Gulf airlines for this variant. First, as the corners are eliminated the flow does not separate at moderate angles of attack or sideslip. Analysis for LinkedIn advertisements. Arbitrary Cross-Section Fuselages When the cross section of the fuselage is not con-strained to be circular, a similar iterative procedure is used, but the design procedure is more straight-forward. 3a shows a lateral view of the fuselage skin 27 perforated by the slots 30. [241] After the negotiation between Airbus and Asiana Airlines,[242] Asiana converted orders of eight A350-800s and one A350-1000 to nine A350-900s. The fuselage (/ ˈ f juː z əl ɑː ʒ /; from the French fuselé "spindle-shaped") is an aircraft's main body section. All A350 passenger models have a range of at least 8,000 nmi (14,816 km). The IMA runs on a 100 Mbit/s network based on the AFDX standard, as employed in the A380, in place of the architecture used on the A330/A340. [189] The A350 Regional was expected to be ordered by Etihad Airways[190] and Singapore Airlines. : 2017-0129R1", "PARIS: A350-1000 delayed to 2017 as Rolls raises XWB thrust", "Airbus delays A350 XWB entry as EADS profits triple", "Airbus delivers first ever A350 XWB to Qatar Airways", "Airbus, Operators Improving A350 Dispatch Reliability Two Years into Service", "Early A350 deployment reflects mature operation", "A350 XWB: six million passengers flown… and counting", "Cathay to replace or upgrade poor quality A350 business seats", "A350 reliability ahead of target: Bregier", "A350-900 deployment highlights broad network coverage", "Airbus working on new Sharklets for A350", "New pictures of the changed Sharklets for A350", "Iberia takes delivery of its first A350-900", "Airbus Debuts A350-1000 at Singapore Airshow", "Does Airbus A350 Laminar Flow Test Signal Production Possibilities? 5-1 d).

This shape is chosen for two reasons. [92], In June 2017 after 30 months in commercial operation, 80 A350s were in service with 12 operators, the largest being Qatar Airways with 17 and 13 each at Cathay Pacific and Singapore Airlines (SIA). Sailplane design question about fuselage cross section. Type certification from the European Aviation Safety Agency (EASA) was obtained in September 2014, followed by certification from the Federal Aviation Administration (FAA) two months later. There are some commercial aircraft that do not follow the circular corss section design standard. [93] The fleet average block time (time between pushback and destination gate arrival) was 7.2 hours with 53% below 3,000 nmi (5,556 km), 16% over 5,000 nmi (9,260 km), and 31% in between. In the homework, the truss design of the aircraft was requested. [183] In February 2018, Qatar Airways stated its preference for the larger -1000, having no need for the extra range of the -900ULR. [210] Airbus then completed functional and reliability testing. Then a full fuselage barrel is optimised, using a PC cluster. [225] Within the June 2016 Airbus Innovation Days, chief commercial officer John Leahy was concerned about the size of a 400-seat market besides the Boeing 747-8 and the 777-9 and chief executive Fabrice Brégier feared such an aircraft could cannibalise demand for the -1000. They may be used by those companies to build a profile of your interests and show you relevant ads on other sites. [185], Airbus Corporate Jet version of the A350, the ACJ350, is derived from the A350-900ULR. Introduction. [144] Engine thrust-reversers and nacelles are supplied by US-based UTC Aerospace Systems. The trick is in combining the stringers with the fiber-placed skin to enable a co-cured structure. [102][better source needed], Airbus expects 10% lower airframe maintenance compared with the original A350 design and 14% lower empty seat weight than the Boeing 777. A high order sandwich theory formulation for two composite facesheets separated by a core is used. Recently for large transport airplanes (airbuses) multideck fuselages are applied. GE believed it can offer a product that outperforms the Trent 1000 and Trent XWB, but was reluctant to support an aircraft competing directly with its GE90-115B-powered 777 variants. Academia.edu is a platform for academics to share research papers. [86] This may have accelerated its retirement of the Airbus A340. The double bubble concept is a fuselage design which achieves a flattened cabin shape without incurring the large bending stress penalty. 1 44 0. [26] The 777 accommodates nine or ten seats per row, with more than half of recent 777s being configured in a ten-abreast layout that will come standard on the 777X. Google Adwords – Opt out – Privacy Policy For example, the Airbus A380 is a triple bubble design. By pointing to the need for Boeing to break from traditional fuselage cross-sections, the analyses by Epstein and Fehrm reveal the challenge of optimising a new aircraft design with a historically unique combination of size and performance. The fuselage (/ ˈ f juː z əl ɑː ʒ /; from the French fuselé "spindle-shaped") is an aircraft's main body section. The Rolls-Royce Trent XWB engine's thrust is augmented to 97,000 lbf (430 kN). This also adds cargo space in terms of cabin depth. This cookie is used to store the language preferences of a user to serve up content in that stored language during session time.

[86], By the end of May 2016, the in-service fleet had flown 55,200 hours over 9,400 cycles at a 97.8% operational reliability on three months. On 2 June 2013, the Trent XWB engines were powered up on the A350 for the first time. Note: The LinkedIn user ID does not contain personally identifiable information. [235] It was designed to supplement the Airbus A330-200 long-range twin. [212] After its maiden flight on 7 December, delivery to launch customer Qatar Airways slipped to early 2018. [37][38] The composite frames would feature aluminium strips to ensure the electrical continuity of the fuselage, for dissipating lightning strikes. Thread OP. [120], Airbus devised a three-pronged main undercarriage design philosophy encompassing both four- and six-wheel bogies to stay within pavement loading limits. [117][137] Airbus stated that the benefits includes reduced maintenance and lower weight because as the IMA replaces multiple processors and LRUs with around 50% fewer standard computer modules known as line-replaceable modules. As of December 2019, A350 XWB orders stand at 926, of which 347 have been delivered and 312 are in operation. [132] The 7M7, if launched, would fill what Boeing marketing vice-president Randy Tinseth has described as a "white space" in the market. [216], It features an automatic emergency descent function to around 10,000 ft (3,000 m) and notifies air traffic control if the crew fails to respond to an alert, indicating possible incapacitation from depressurisation. Wing and Fuselage Structural Optimization Considering Alternative Material Systems By Jonathan Lusk B.S.A.E., University of Kansas, 2006 Submitted to the Department of Aerospace Engineering and the Faculty of the Graduate School of the University of Kansas in partial fulfillment of the requirements for the degree of Masters of Engineering. by Kip. [181] It burned 101.4 t (224,000 lb) of fuel to cover the route in 17 h 22 min: an average of 5.8 tonnes per hour (1.6 kg/s). Cross-Section Design It is often reasonable to start the fuselage layout with a specification of the cross-section: its shape and dimensions. [232], In January 2010, Airbus opted to develop the -800 as a shrink of the baseline -900 in order to avoid a specific development and increase its payload by 3 t (6,600 lb) or its range by 250 nmi (460 km), but this led to a fuel burn penalty of "a couple of%", according to John Leahy. [188] Engine thrust would have been reduced to 70,000–75,000 lbf (310–330 kN) from the standard 85,000 lbf (380 kN) and the variant would have been optimised for routes up to 6,800 nmi (12,600 km) with seating for up to 360 passengers in a single-class layout. Remembers the user's selected language version of a website, Used by the social networking service, LinkedIn, for tracking the use of embedded services. [201] The main landing gear is a 6-wheel bogie instead of a 4-wheel bogie, put in a one frame longer bay. Registers a unique ID that is used to generate statistical data on how the visitor uses the website. [108] The cabin's internal width is 5.61 m (18.4 ft) at armrest level compared to 5.49 m (18.0 ft) in the Boeing 787[109] and 5.87 m (19.3 ft) in the Boeing 777. [93], In October 2017, Airbus was testing extended sharklets, which could offer 100–140 nmi (185–259 km) extra range and reduce fuel burn by 1.4–1.6%. [148], The ram air turbine, capable of generating 100 kilovolt-ampere, is supplied by Hamilton Sundstrand and located in the lower surface of the fuselage. [31] However, it was decided programme costs are to be borne mainly from cash-flow. In 2010, after low-speed wind tunnel tests, Airbus finalised the static thrust at sea level for all three proposed variants to the 74,000–94,000 lbf (330–420 kN) range. [93] Singapore Airlines operated the longest leg, Singapore to San Francisco 7,340 nmi (13,594 km), and the shortest leg, Singapore to Kuala Lumpur 160 nmi (296 km). This online tutorial program is designed to guide users of all experience levels though the Open Vehicle Sketch Pad parametric geometry design tool. Three flight test aircraft was planned with entry into service scheduled for mid-2017. [162] It will enable non-stop Manila-New York City flights without payload limitations in either direction,[163] a 7,404 nmi (13,712 km) flight. During the wing design process, eighteen parameters must be determined. [225] A potential 4 m stretch would remain within the exit limit of four door pairs, and a modest MTOW increase from 308 t to 319 t would need only 3% more thrust, within the Rolls-Royce Trent XWB-97 capabilities, and would allow a 14,100 km (7,600 nmi) range to compete with the Boeing 777-9 capabilities. [51] US-based Rockwell Collins and Moog Inc. were chosen to supply the horizontal stabiliser actuator and primary flight control actuation, respectively. We also allow third parties to use tracking technologies for similar purposes. [41][42][43] Rolls-Royce agreed with Airbus to supply a new variant of the Trent turbofan engine for the A350 XWB, named Trent XWB. Airline dissatisfaction with this proposal motivated Airbus to commit €4 billion to a new airliner design. [88], In January 2017, two years after introduction, 62 aircraft were in service with 10 airlines. Youtube – Opt out – Privacy policy. [199] The 7 m (23 ft) extension seats 40 more passengers with 40% more premium area. You can set your browser to block or alert you about these cookies, but some parts of the site may not work then. The average flight was 6.8 hours, with the longest average being 9.6 hours by TAM Airlines and the shortest being 2.1 hours by Cathay Pacific's. Service entry would be determined by ultra-high bypass ratio engine developments pursued by Pratt & Whitney, testing its Geared Turbofan upgrade; Safran Aircraft Engines, ground testing a demonstrator from 2021; and Rolls-Royce, targeting a 2025 Ultrafan service entry. 16. Although its launch is not guaranteed, it would be delivered in the mid-2020s, after the A321XLR and a stretched A320neo "plus", potentially competing with the Boeing New Midsize Airplane. [239] He later confirmed at a September 2014 press conference that development of the A350-800 had been "cancelled. It holds crew, passengers, and cargo.In single-engine aircraft, it will usually contain an engine, as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. [209] Flight tests allowed raising the MTOW from 308 to 316 t (679,000 to 697,000 lb), the 8 t (18,000 lb) increase giving 450 nmi (830 km) more range. in terms of seat design, placement, and storage space or it may be to satisfy the structural support for wing and tail forces acting in flight etc. Parker estimates the contracts will generate more than US$2 billion in revenues over the life of the programme. However, Shanley has shown that another parameter better captures the efficiency of the frame in bending. [205] In February 2016, final assembly started at the A350 Final Assembly Line in Toulouse. The crew rest areas in the Boeing 777 are a good example of using otherwise unproductive space in a circular-cross section. [84] The first delivery to launch customer Qatar Airways took place on 22 December 2014. [150] In late 2015, A350 XWB msn. [191] Since 2013, there has been no further announcement about this variant. These cookies allow us to count visits and traffic sources, so we can measure and improve the performance of our site. [77], The A350 received type certification from the European Aviation Safety Agency (EASA) on 30 September 2014. [93][70] Seating varied from 253 for Singapore Airlines to 389 for Air Caraïbes, with most between 280 and 320. 23 497 7. [99] In section 5, a tight coupling integration is presented. [212], Its basic 308 t (679,000 lb) MTOW was increased to 311 t (686,000 lb) before offering a possible 316 t (697,000 lb) version. Further recent publications concerning the subject are listed. It features frames designed to create the shell of the fuselage, which are secured via cross sections on a rigid fixture. Today manufacturers are blowing aircraft as bubbles, but tomorrow they may offer a completely different approach to plane design. [132], The manufacturer has extensively used computational fluid dynamics and also carried out more than 4,000 hours of low- and high-speed windtunnel testing to refine the aerodynamic design. [174], Singapore Airlines, the launch customer, used its seven -900ULR aircraft on non-stop flights between Singapore and New York City and cities on the U.S. west coast. It is of major importance for the design of the fuselage as the systems affect the overall arrangement of it. [47][48] In June 2007, John Leahy indicated that the A350 XWB would not feature the GEnx engine, saying that Airbus wanted GE to offer a more efficient version for the airliner. [80] On 12 November 2014, the A350 received certification from the FAA. of the elliptical cross-section with respect to θ is defined by a polar equation as follows r ellipse(θ) = ab p b 2cos(θ) +a2 sin(θ). This will enable a 8,100 nmi (15,000 km) range with 325 seats in a three-class layout. [6], A350 XWB msn. So by indenting the fuselage (reducing the volume of the fuselage) at the waist, the cross-sectional area is maintained as smooth as possible, providing almost a uniform and continuous area of smooth interaction to the airflow. Used by Google DoubleClick to register and report the website user's actions after viewing or clicking one of the advertiser's ads with the purpose of measuring the efficacy of an ad and to present targeted ads to the user. [65], The production rate was expected to rise from three aircraft per month in early 2015 to five at the end of 2015, and would ramp to ten aircraft per month by 2018. As result the fuselage cross section may not be in the form as a circular cross section. Neither double bubble nor triple bubble designs require extra strength, except that the floors must be designed to take the tension at the bubble junctions. Forgeard did not give a project name, and did not state whether it would be an entirely new design or a modification of an existing product. After designing the truss, it is expected to create a finite element model. They may be set by us or by third party providers whose services we have added to our pages. 1., a,b,c. Today’s passenger aircraft have a constant fuselage cross-section in the central section. The double bubble concept applied to a small airliner as a vertical configuration can expand the usable cabin and cargo space. The revised design of the A350 XWB's glass cockpit dropped the A380-sized display and adopted 38 cm (15 in) liquid-crystal display screens. For current aircraft a method called the `inside-out approach' is used, where the design of the fuselage is dictated by the requirements for the passenger and cargo compartment. As shown in Fig. The A350's IMA will manage up to 40 functions (versus 23 functions for the A380) such as undercarriage, fuel, pneumatics, cabin environmental systems, and fire detection. This initial estimate of empennage size is important for calculating the aircraft mass and center of gravity. They had accumulated 25,000 flights over 154,000 hours with an average daily utilisation of 12.5 hours, and transported six million passengers with a 98.7% operational reliability. This is important not only for passengers, but also for pilots managing the aircraft. The onboard Maintenance, Repair, Overhaul network needed software improvements. [136] Airbus says the cockpit design allows for future advances in navigation technology to be placed on the displays plus gives flexibility and capacity to upload new software and to combine data from multiple sources and sensors for flight management and aircraft systems control. [149] In light of the Boeing 787 Dreamliner battery problems, in February 2013 Airbus decided to revert from lithium-ion to the proven nickel-cadmium technology although the flight test programme will continue with the lithium-ion battery systems. [134] The wingtip device curves upwards over the final 4.4 m (14 ft). [13][14], On 6 October 2005, the programme's industrial launch was announced with an estimated development cost of around €3.5 billion. It features frames designed to create the shell of the fuselage, which are secured via cross sections on a rigid fixture. Pressurized aircraft generally have cylindrical fuselage cross-sections as this is the most efficient shape to resist the internal pressure. Examples of past studies [1]-[8] related to aerodynamic characteristics due to the fu-selage configuration include missiles which studied effect on the location of vortex breakdown on the delta wing. Chief operating officer, John Leahy indicated existing A350 contracts were being re-negotiated due to price increases compared to the original A350s contracted. [137] A head-up display is also present in the cockpit. It has a new fuselage designed around a nine-abreast economy cross-section, up from the eight-abreast A330/A340. In 2017, average test flights before delivery decreased to 4.1 from 12 in 2014, with an average delay down to 25 days from 68. [234] The −800's fuselage is 10 frames shorter (six forward and four aft of wing) than the −900 aircraft. [236] Airbus planned to decrease structural weight in the -800 as development continued, which should have been around airframe 20. er fuselage cross section compared with that of aircrafts. It allows for an eight-abreast 2–4–2 arrangement in a premium economy layout, with the seats being 49.5 cm (19.5 in) wide between 5 cm (2.0 in) wide arm rests. [53] On 4 February 2010, Airbus signed a contract with Panasonic Avionics Corporation to deliver in-flight entertainment and communication (IFEC) systems for the Airbus A350 XWB. The company planned to announce this version at the 2004 Farnborough Airshow, but did not proceed. fuselage design which achieves a flattened cabin shape without incurring the large bending stress penalty Have you flown one? [67] Airbus announced plans to increase its production rate from 10 monthly in 2018 to 13 monthly from 2019, while the Boeing 787 production will increase from 12 to 14 per month in 2019, and six A330 are produced monthly. It seats 350-410 passengers in a typical three-class layout with a range of 8,700 nmi (16,100 km). [95] In the case of circular fuselage cross sections, the fuselage teardrop is determined uniquely by the distribution of the radii R(x) (Fig. [62] The forward fuselage of the first A350 was delivered to the final assembly plant in Toulouse on 29 December 2011. [39] Airbus used a full mock up fuselage to develop the wiring, a different approach from the A380, on which the wiring was all done on computers. Semi monocoque fuselage design usually uses combination of stringers, bulkheads, and frames to reinforce the skin and maintain the cross sectional shape of the fuselage. Used by Youtube to registers an unique ID to keep statistics of what videos from YouTube the user has seen. "[17], Airbus responded that they were considering A350 improvements to satisfy customer demands. The name double bubble is a direct one as the configuration reminds of two soap bubbles joined together by one membrane. The order replaced the February agreement for 30 A350s and 40 A330Neos, compensating the cancellation for 39 A380s, causing the end of the double-decker production. [170] The MTOW is increased by 5 tonnes from the previously certified 275 tonnes variant. [27] The A350 cabin is 12.7 cm (5.0 in) wider at the eye level of a seated passenger than the 787's cabin,[28] and 28 cm (11 in) narrower than the Boeing 777's cabin (see the Wide-body aircraft comparison of cabin widths and seating). It has a common type rating with the A330. [22] Within four days, Singapore Airlines agreed to order 20 A350 XWBs with options for another 20 A350 XWBs.[23]. [81] On 1 August 2017, the EASA issued an airworthiness directive mandating operators to power cycle (reset) early A350-900s before 149 hours of continuous power-on time, reissued in July 2019. Hence, the fuselage is not circular, but a double bubble, the advantage of which is more storage space for passenger items. As a result of the increased fuel capacity from the -900ULR, the ACJ350 has a maximum range of 20,000 km (10,800 nmi).
