With a 660,000 lb (299 t) MTOW and 90,000 lbf (400 kN) engines, it has a range of 6,005 nautical miles (11,121 km; 6,910 mi) with 368 passengers in three-class. 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.
- The 4.5 ft (1.37 m) wider wing was to be strengthened and the fuel capacity enlarged, and it was to be powered by simple derivatives with similar fans.
- 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.
- After having considered a -200ER P2F program, Boeing was hoping to conclude its study by the fall as the 777X replacing aging -300ERs from 2020 will generate feedstock.
- The fly-by-wire system also incorporates flight envelope protection, a system that guides pilot inputs within a computer-calculated framework of operating parameters, acting to prevent stalls, overspeeds, and excessively stressful maneuvers.
The 777 was completed with such precision that it was the first Boeing jetliner that did not require the details to be worked out on an expensive physical aircraft mock-up. In January 1993, a team of United developers joined other airline teams and Boeing designers at the Everett factory. Alan Mulally served as the Boeing 777 program’s director of engineering, and then was promoted in September 1992 to lead it as vice-president and general manager. The company opted for the twin-engine configuration given past design successes, projected engine developments, and reduced-cost benefits.
The first fatality involving the twinjet occurred in a fire while an aircraft was being refueled at Denver International Airport in the United States on September 5, 2001, during which a ground worker sustained fatal burns. The program started in 2011, with the first ecoDemonstrator aircraft flying in 2012. KMC claims this requires less structural reinforcement, which results in a lighter and more fuel-efficient aircraft. The provides seating for 395 passengers and has a range of 8,745 nmi (16,196 km; 10,064 mi), while the has seating for 426 passengers and a range of over 7,285 nmi (13,492 km; 8,383 mi).
The Boeing 777 Game Changer
Whether you’re in economy class or business class, the cabin feels roomy and modern. 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. Enjoy more room to stretch out and greater privacy in Business Class – our seats are now all in pairs, with six in each row. The first refreshed aircraft are taking off.
The Story Behind Boeing 777
- This marked the start of an 11-month flight test program that was more extensive than testing for any previous Boeing model.
- The 777 is a long-range jet, able to connect cities halfway across the world without refueling.
- The higher-thrust variants, GE90-110B1 and -115B, have a different architecture from that of the earlier GE90 versions.
- In 2013, Boeing announced that the upgraded 777X models would incorporate airframe, systems, and interior technologies from the 787.
- The 777 was the first commercial aircraft to be developed using an entirely computer-aided design (CAD) process.
Outboard as well as center stowage units are designed to open downward for convenient loading. It has the highest schedule reliability of any twin aisle airplane at 99.5 percent – the airplane is on time, nearly all the time. The 777 delivers exceptional performance, passenger comfort and low operating cost. Cairo International AirportBuilding No. 1 – Hall No. 3 In the skies or on the ground, the Boeing 777 is a true engineering marvel.
Passenger Comfort:
The higher-thrust GE90 variants are the first production engines to feature swept rotor blades. 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. 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 wings are designed with increased thickness and a longer span than previous airliners, resulting in greater payload and range, improved takeoff performance, and a higher cruising altitude. The is a further stretched variant with a capacity of over 400 passengers and a range of over 8,200 nmi (15,200 km; 9,400 mi), whereas the is slated to seat approximately 350 passengers and have a range of over 9,300 nmi (17,200 km; 10,700 mi). These changes were to increase fuel efficiency and allow airlines to add 14 additional seats to the airplane, increasing per seat fuel efficiency by 5%.
The Award-Winning Boeing 777 Signature Experience
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. This marked the start of an 11-month flight test program that was more extensive than testing for any previous Boeing model.
Now’s the perfect time to extend your success.
It was the first commercial airplane to be fully designed on computers, which allowed for better precision and faster development. The 777 is a jet that’s perfectly designed for long-range flights without breaking the bank on operating costs. As of late 2023 the 777 program was launching three new aircraft every month. By the time manufacturing of the 777 began in 1993 at Boeing’s factory in Everett, Washington, the manufacturer had received 118 orders for the aircraft from 10 airlines. Cabins were designed with flexibility zones and easily removable components, allowing for configuration changes in a fraction of the time required for other aircraft.
A ram air turbine—a small retractable device which can provide emergency power—is also fitted in the wing root fairing. Folding wingtips reemerged as a design feature at the announcement of the upgraded 777X in 2013. In 2013, a new wing made of composite materials was introduced for the upgraded 777X, with a wider span and design features based on the 787’s wings. The fly-by-wire system also incorporates flight envelope protection, a system that guides pilot inputs within a computer-calculated framework of operating parameters, acting to prevent stalls, overspeeds, and excessively stressful maneuvers.
The new flight control software would eliminate the need for the tail skid by keeping the tail off the runway surface regardless of the extent to which pilots command the elevators. These improvements, of which the latter is the most important and was derived from work to develop the 787, were stated by GE to lower fuel burn by 0.5%. More changes were targeted for late 2012, including possible extension of the wingspan, along with other major changes, including a composite wing, a new generation engine, and different fuselage lengths. Through these improvements, the 777 remains the largest twin-engine jetliner in the world. On February 24, 2003, the -300ER made its first flight, and the FAA and EASA (European Aviation Safety Agency, successor to the JAA) certified the model on March 16, 2004. General Electric offered to develop the GE90-115B engine, while Rolls-Royce proposed developing the Trent 8104 engine.
Seating options range from four to six–abreast in first class up to ten–abreast in economy. The aircraft has triple redundant hydraulic systems with only one system required for landing. This helps reduce weight and simplifies the aircraft’s braking and hydraulic systems.
The aircraft sustained structural, heat and smoke damage, and was written off. The aircraft was evacuated with no injuries, and airport fire teams extinguished the fire. Two other minor momentary losses of thrust with Trent 895 engines occurred later in 2008. It entered service with Ethiopian Airlines in December 2024 on lease from Altavair. Emirates is the largest airline operator as of 2018update, and is the only customer to have operated all 777 variants produced, including the -200, -200ER, -200LR, -300, -300ER, and 777F. Various airframes have been used since to test a wide variety of technologies in collaboration with a range of industrial partners.
Customers’ expectations for continually better performance keep the airplane evolving, further distinguishing it from the competition. These new offerings further demonstrate Boeing’s commitment to helping customers maximize profits and enhance the passenger flying experience. The combination of baseline and priced optional features will result in an approximate five percent overall fuel use per seat improvement. Renowned for its comfort and convenience, it features spacious overhead bins that make it easier for travelers to stow carry-on luggage close to their seats. Comfort at every seat and convenience throughout the cabin makes flying productive for business travelers, restful for leisure travelers and enjoyable for all on board. Further enhancing the flying experience, the 777 passenger windows are 12% larger than the A350.
The aircraft in question was built for the airline Emirates, and rolled out of the production facility in March 2012. In 2010, Boeing announced plans to increase production from 5 aircraft per month to 7 aircraft per month by mid-2011, and 8.3 per month by early 2013. 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. 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.
The six-wheel bogies are designed to spread the load of the aircraft over a wide area without requiring an additional centerline gear. The aircraft features the largest landing gear and the biggest tires ever used in a commercial jetliner. Folding wingtips, 21 feet (6.40 m) long, were offered when the 777 was first launched, to appeal to airlines who might use gates made to accommodate smaller aircraft, but no airline purchased this option. The wings also serve as fuel storage, with longer-range models able to carry up to 47,890 US gallons (181,300 L) of fuel.
The 1,000th 777 off the production line, a -300ER set to be Emirates’ 102nd 777, was unveiled at a factory ceremony in March 2012. Kansas Modification Center claims a maximum payload of 205,000 lb (93 t), room for 47 pallets, and a range of about 5,400 nmi (10,000 km; 6,200 mi) at maximum payload. By March 2023, IAI had a backlog of over 60 orders, and completed the first flight of its prototype. After having considered a -200ER P2F program, Boeing was hoping to conclude its study by the fall as the 777X replacing aging -300ERs from 2020 will generate feedstock. At Mach 0.839 (495 kn; 916 km/h), FL300, -59 °C and at a 513,400 lb (232.9 t) weight, it burns 17,300 lb (7.8 t) of fuel per hour. It is powered by the GE90-115B turbofan, the world’s most powerful jet engine with a maximum thrust of 115,300 lbf (513 kN).
The -300ER, which combined the -300’s added capacity with the -200ER’s vegas casino app range, became the top-selling 777 variant in the late 2000s, benefitting as airlines replaced comparable four-engine models with twinjets for their lower operating costs. 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. The 777 Freighter (777F) is an all-cargo variant which shares several features with the -200LR, including its airframe, engines, and fuel capacity. In designing the 777 as its first fly-by-wire commercial aircraft, Boeing decided to retain conventional control yokes rather than change to sidestick controllers as used in many fly-by-wire fighter aircraft and in many Airbus airliners.
