Boeing 777X Wikipedia

First deliveries are planned for May 2020 while the first production wing spar was going to be loaded in early December. By late 2019, it should be joined in the flight program by the other four prototypes which were undergoing assembly. By September, the static test 777X article was completed, lacking engines and various systems, ahead of its structural testing on ground. The first wing was completed in May for static tests before the flight test wings. The wings are the first produced by Boeing in composite and not out-sourced like for the 787, and production is largely automated as well. A major leap in automated production, it drills the tens of thousands of holes in the fuselage more quickly, accurately, and safely.

With a 656,000 lb (298 t) MTOW and 93,700 lbf (417 kN) engines, it has a 7,065 nmi (13,084 km; 8,130 mi) range with 301 passenger seats in a three-class configuration. With a 545,000 lb (247 t) MTOW and 77,000 lbf (340 kN) engines, it has a range of 5,240 nautical miles (9,700 km; 6,030 mi) with 305 passenger seats in a three-class configuration. Located above the main cabin and connected via staircases, the forward flight crew rest contains two seats and two bunks, while the aft cabin crew rest features multiple bunks.

In July 2021, Boeing CEO David Calhoun viewed a freighter version as a logical next aircraft program to comply with emerging ICAO aircraft emission standards. It would seat typically 395 passengers with a range of 8,745 nmi (16,170 km; 10,050 mi). For the longer 777-9, replacing the engines should improve fuel consumption by 10%, with the longer, carbon-fiber wings adding an estimated 7% improvement. On October 11, 2024, Boeing confirmed that the expected first delivery of the aircraft had slipped to 2026, following development challenges and workplace strikes at the company. After the first delivery was pushed back from 2021 to 2022, the third aircraft made its maiden flight on August 3; it is slated for avionics systems, APU, flight loads and propulsion performance tests. By mid-November, a pair of flight compliant engines were installed on the first 777-9.

Advanced alloys saved 1,450 kilograms (3,200 pounds) of structural weight on the 777. Raked wingtips were added to improve overall aerodynamic efficiency, extending each wing by 2 meters (6.5 feet). On January 31, 2022, Qatar Airways became the launch customer for the 777X Freighter program, with an order of up to 50 Boeing Freighters, expanding its commitment to the Boeing 777X family. On November 7, 2019, Lufthansa stated it had converted 14 orders into options, leaving 6 firm commitments, after having negotiated a change as part of its order for s. On February 14, 2019, it was reported that Etihad would take only 6 of the X airliners it had originally ordered.

The high degree of commonality among all 777 models gives airlines the opportunity to minimize spares, equipment, and training costs. In late 2011, the new- generation 777s with GE engines received type-design approval from the FAA for ETOPS up to 330 minutes. The ability to carry revenue cargo with a full passenger load gives airlines the flexibility to negotiate long-term contracts for time-definite shipments.

Freighters

• A third passenger died six days later as a result of injuries sustained during the crash.
• Boeing built a 1,300,000 sq ft (120,000 m2) building adjacent to the Everett factory, with a 120 ft (37 m) autoclave, and a robot to wind fiber for the wings.
• The 777 was first flown on June 12, 1994, and commercial service commenced on June 7, 1995.
• Open and spacious, the 777 has a wider cabin and larger windows than any competing airplane.
• Optimized engine integrationAdvanced computational tools used to optimally design nacelle together with wing
• The preliminary investigation indicated that the aircraft was attempting a landing during active wind shear conditions.

It holds the world record for the longest nonstop flight by a commercial airliner. Boeing uses two characteristics – fuselage length and range – to define its 777 models. The higher-thrust GE90 variants are the first production engines to feature swept rotor blades.

The first commercial flight took place on June 7, 1995, from London Heathrow Airport to Dulles International Airport near Washington, D.C. Longer ETOPS clearance of 207 minutes was approved in October 1996.a At the successful conclusion of flight testing, the 777 was awarded simultaneous airworthiness certification by the US Federal Aviation Administration (FAA) and European Joint Aviation Authorities (JAA) on April 19, 1995. To satisfy ETOPS requirements, eight 180-minute single-engine test flights were performed.

Boeing: 777 Design Highlights

The National Aeronautic Association (NAA) recognized the Boeing Company and the 777 team with its Robert J. Collier Trophy for 1995 for their work designing, manufacturing, and introducing the 777 into service. A prototype was released in April 1994, and the first flight of a 777 was on June 12, 1994, marking the beginning of an 11-month test program. The 777 is the first commercial American-made plane to use a fly-by-wire flight control system, in which pilots control rudders and flaps electronically. The Boeing 777 was designed by using CATIA, a three-dimensional design technology that incorporated digital design, engineering, and manufacturing.

Boeing in the Middle East

• It would have been powered by 99,500 lbf (443 kN) engines, targeting per-seat 21% better fuel burn and 16% better operating cost.
• Boeing acknowledged that the GE9X engine would have sufficient margin to power a stretched variant.
• As of the end of 2022 Boeing had received over 2,100 orders for the 777 and had made more than 1,600 deliveries of it to some 60 customers since the 777’s introduction, making it the aircraft with the most orders and deliveries of any wide-body jetliner.

The eight airlines that contributed to the design process became known within Boeing as the “Working Together” group. Airline planners’ requirements for larger aircraft had become increasingly specific, vegas casino apk adding to the heightened competition among aircraft manufacturers. In the early 1970s, the Boeing 747, McDonnell Douglas DC-10, and the Lockheed L-1011 TriStar became the first generation of wide-body passenger airliners to enter service. As of 2018update, Emirates was the largest operator with a fleet of 163 aircraft. In November 2013, Boeing announced the development of the third generation 777X (variants include the 777-8, 777-9, and 777-8F), featuring composite wings with folding wingtips and General Electric GE9X engines, and slated for first deliveries in 2027. These second-generation 777 variants have extended raked wingtips and are powered exclusively by 110,000–115,300 lbf (489–513 kN) GE90 engines.

Several aircraft have also been fitted with VIP interiors for non-airline use. The 777’s windows were the largest of any current commercial airliner until the 787, and measure 15 by 10 inches (380 by 250 mm) for all models outside the and -9. The aircraft has triple redundant hydraulic systems with only one system required for landing.

From the program’s start, Boeing had considered building ultra-long-range variants. New production methods were developed, including a turn machine that could rotate fuselage subassemblies 180 degrees, giving workers access to upper body sections. To accommodate production of its new airliner, Boeing doubled the size of the Everett factory at the cost of nearly US$1.5 billion (~$2.93 billion in 2024) to provide space for two new assembly lines. An agreement between Boeing and the Japan Aircraft Development Corporation, representing Japanese aerospace contractors, made the latter risk-sharing partners for 20 percent of the entire development program. International contributors included Mitsubishi Heavy Industries and Kawasaki Heavy Industries (fuselage panels), Fuji Heavy Industries, Ltd. (center wing section), Hawker de Havilland (elevators), and Aerospace Technologies of Australia (rudder). At 242.4 ft (73.9 m) in length, the -300 became the longest airliner yet produced (until the A ), and had a 20 percent greater overall capacity than the standard length model.

Digitally Designed

The gentle contour of the walls, ceiling, and integrated stowage bins allows tall passengers to enter the aisle and return to their seat without stooping. A wide cabin and open sight lines provide the ideal setting for the airline’s signature service. The 777 cabin is designed to make every passenger aspire to be a frequent passenger. Large flat‐panel displays present flight information in a readily accessible form, allowing pilots to quickly analyze flight parameters for safety, schedule, passenger comfort, and economics. Thoroughly integrated displays, controls, and automation work together to enhance the pilot‐airplane interface while making flight deck procedures efficient.

Aircraft Numbers 1 and 6 were planned to be used for ground tests; four 777-9s (No. 2 to 5) were slated for the flight test and certification campaign, with two 777-8s to come later. In April 2017, the initial one-piece wing spar came onto the assembly jig and was about to enter lay-up in June; first parts assembly for the initial -9, a static test airframe, were underway in the purpose-built wing center near Everett, Washington. Boeing built a 1,300,000 sq ft (120,000 m2) building adjacent to the Everett factory, with a 120 ft (37 m) autoclave, and a robot to wind fiber for the wings. In December 2014, Boeing began construction on a 367,000 sq ft (34,100 m2) composites facility in St. Louis to be completed in 2016, to build 777X parts with six autoclaves for the wing and empennage parts, starting in 2017. Airbus points out that handling more than one engine type adds millions of dollars to an airliner cost.

The 240 design teams, with up to 40 members each, addressed almost 1,500 design issues with individual aircraft components. This was a departure from industry practice, where manufacturers typically designed aircraft with minimal customer input. The jetliner is recognizable for its large-diameter turbofan engines, raked wingtips, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped tail cone. The Triple Seven can accommodate a ten–abreast seating layout and has a typical 3-class capacity of 301 to 368 passengers, with a range of 5,240 to 8,555 nautical miles nmi (9,700 to 15,840 km; 6,030 to 9,840 mi). The 777 is the world’s largest twinjet and the most-built wide-body airliner.The jetliner was designed to bridge the gap between Boeing’s other wide body airplanes, the twin-engined 767 and quad-engined 747, and to replace aging DC-10 and L-1011 trijets.

Nine aircraft fitted with General Electric, Pratt & Whitney, and Rolls-Royce engines were flight tested at locations ranging from the desert airfield at Edwards Air Force Base in California to frigid conditions in Alaska, mainly Fairbanks International Airport. Whether it’s flying passengers across the globe or transporting vital cargo, this aircraft is built to stay relevant in an ever-changing industry. Airlines around the world are looking for efficient, long-range aircraft that can handle high passenger volumes without skyrocketing costs.

Resistant to fatigue and corrosion, composite materials reduce maintenance time, saving airlines money and increasing airplane availability. Optimized engine integrationAdvanced computational tools used to optimally design nacelle together with wing Raked wingtipImproved fuel efficiency and lighter weight alternative to a vertical winglet Optimized for the greatest lift with the least drag, the advanced wing shape allows the 777 to climb quicker, cruise faster and higher, and consume less fuel during cruise. On August 6, 2025, Cathay Pacific ordered an additional 14 aircraft, which brings the airline’s total commitment to 35 airframes. The deal also includes 8 spare engines plus two options and a maintenance service contract for the General Electric GE9X engines.

Initial design

With the launch of the 777X in 2013, Boeing confirmed that the aircraft would be receiving a new interior featuring 787 cabin elements and larger windows. This helps reduce weight and simplifies the aircraft’s braking and hydraulic systems. The six-wheel bogies are designed to spread the load of the aircraft over a wide area without requiring an additional centerline gear.

It quickly became a favorite for long-range routes, where reliability and efficiency are crucial. The Boeing 777 had its first flight on June 12, 1994, and it was an instant hit. When we talk about game-changing planes in the skies, the Boeing 777 often tops the list. These new offerings further demonstrate Boeing’s commitment to helping customers maximize profits and enhance the passenger flying experience.

With one of the best safety records in commercial aviation, the 777 gives passengers and airlines peace of mind. From its design to its performance, it’s built to impress airlines and passengers. Airlines and passengers alike love it for its fuel efficiency, spacious cabins, and impressive range. Carrying lucrative cargo payloads with a full passenger load, the 777 allows airlines to supplement passenger revenues on routes where less-capable airplanes cannot carry cargo when all seats are sold.

The development phase of the 777 coincided with United Airlines replacement program for its aging DC-10s. By 1988, Boeing realized that the only answer was a clean-sheet design, which became the twinjet 777. In 1986, Boeing unveiled proposals for an enlarged 767, tentatively named 767-X, to target the replacement market for first-generation wide-bodies such as the DC-10, and to complement existing 767 and 747 models in the company lineup. The trijet “777” was later dropped, following marketing studies that favored the 757 and 767 variants.

Airlines loved its performance, and passengers enjoyed the extra comfort. Back in the 1980s, Boeing started working on this idea, listening to airlines to create a plane that hit the sweet spot. The Boeing 777 was born out of a simple need, airlines wanted a plane bigger than the 767 but smaller than the 747. Customers’ expectations for continually better performance keep the airplane evolving, further distinguishing it from the competition. The combination of baseline and priced optional features will result in an approximate five percent overall fuel use per seat improvement. Optional priced features allow operators to accommodate more seats for more revenue and further improve fuel efficiency per seat.
