Boeing 777 Wikipedia

Following flight testing, aerodynamic refinements have reduced fuel burn by an additional 1.4%. As of April 2021update, 247 aircraft had been ordered by 25 customers, with 45 orders remaining unfilled. The 777F includes a supernumerary area forward of the rigid cargo barrier with four business-class seats, two crew bunks, a galley, and a lavatory. The closest competing aircraft from Airbus are the discontinued A HGW and the current A ULR. It has a maximum design range of 8,555 nautical miles (15,844 km; 9,845 mi) as of 2017update. The value of a new -200ER rose from US$110 million at service entry to US$130 million in 2007; a 2007 model 777 was selling for US$30 million ten years later, while the oldest ones had a value around US$5–6 million, depending on the remaining engine time.

The 777 Freighter, or 777F, was released in 2008, having been designed specifically to carry cargo. It is the world’s largest two-engine jet (twin jet), and more than vegas casino app 1, s were in operation in the early 2020s. The new Boeing 777X will be the world’s largest and most efficient twin-engine jet, unmatched in every aspect of performance. Several countries also restricted flights of PW4000-equipped 777s in their territory. The captain declared an emergency and returned to land at the Denver airport.

• Boeing uses two characteristics – fuselage length and range – to define its 777 models.
• Electronic checklists, which airlines can customize with airline-specific information and procedures, speed preflight checks and save valuable minutes that can buffer departure schedules.
• Cabins were designed with flexibility zones and easily removable components, allowing for configuration changes in a fraction of the time required for other aircraft.
• Airlines can arrange the seating to maximize comfort and capacity, making it a favorite for long flights.

Operators

From its design to its performance, it’s changed the way we think about air travel. Airlines are retiring older, less efficient jets in favor of newer, fuel-saving models like the 777. The Boeing 777 has proven itself as a leader in commercial aviation, but what does the future hold? The cabin is spacious, the air feels fresher thanks to advanced systems, and there’s plenty of room for luggage. The 777 is a long-range jet, able to connect cities halfway across the world without refueling.

• 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.
• It can cover long-range routes without needing a refuel, which is a big deal for airlines trying to connect cities like Dubai to Los Angeles or Sydney to London.
• By 2004, the airliner accounted for the bulk of wide-body revenues for Boeing Commercial Airplanes.
• Through these improvements, the 777 remains the largest twin-engine jetliner in the world.

Future Prospects: What’s Next for the Boeing 777?

In late 1991, Boeing selected its Everett factory in Washington, home of 747 (and, later, 787) production, as the 777’s final assembly line (FAL). 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.

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.

United Airlines received its first delivery on June 7, 1995, and the aircraft entered commercial service with the airline on that date, flying from London’s Heathrow Airport to Dulles International Airport near Washington, D.C. It followed the medium-range narrow-body 757 and the medium-to-long-range wide-body 767, which Boeing designed in tandem and introduced into commercial service in the early 1980s. The 777 was the first aircraft to be designed entirely by using a computer, and it was the first completely new commercial jet aircraft developed by the Boeing Company in more than a decade. Two passengers, who had not been wearing their seatbelts, were ejected from the aircraft during the crash and were killed.

The first member of the 777X family was projected to enter service in 2020 at the time of the program announcement. Boeing was also redesigning the inboard flap fairings to reduce drag by reducing pressure on the underside of the wing. Under the deal with General Electric, Boeing agreed to only offer GE90 engines on new 777 versions. A more powerful engine in the thrust class of 100,000 lbf (440 kN) was required, leading to talks between Boeing and engine manufacturers.

The Award-Winning Boeing 777 Signature Experience

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. 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. Baseline engine, weight and aerodynamic improvements will be phased into production by the third quarter of 2016, improving fuel efficiency by two percent.

The preliminary investigation indicated that the aircraft was attempting a landing during active wind shear conditions. All 298 people (283 passengers and 15 crew) on board were killed, making this the deadliest crash involving the Boeing 777. On July 29, 2015, an item later identified as a flaperon from the still missing aircraft was found on the island of Réunion in the western Indian Ocean, consistent with having drifted from the main search area. Air Traffic Control’s last reported coordinates for the aircraft were over the South China Sea.

Built for Passengers:

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).

Preferred by Passengers

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.

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. However, the -100X would have carried fewer passengers than the -200 while having similar operating costs, leading to a higher cost per seat. In March 2018, as previously predicted, the 777 overtook the 747 as the world’s most produced wide body aircraft. In 2018, assembling test aircraft was expected to lower output to an effective rate of 5.5 per month. By 2004, the airliner accounted for the bulk of wide-body revenues for Boeing Commercial Airplanes. Offering greater long-haul performance, the variant became the most widely ordered version of the aircraft through the early 2000s.

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.

Along with traditional yoke and rudder controls, the cockpit features a simplified layout that retains similarities to previous Boeing models. In 2003, Boeing began offering the option of cockpit electronic flight bag computer displays. Mindful of the long time required to bring the 777X to the market, Boeing continued to develop improvement packages which improve fuel efficiency, as well as lower prices for the existing product. The outboard raked wingtip was to have a divergent trailing edge, described as a “poor man’s airfoil” by Boeing; this was originally developed for the McDonnell Douglas MD-12 project.

On February 29, 2000, Boeing launched its next-generation twinjet program, initially called 777-X, and began issuing offers to airlines. By the late 1990s, design plans shifted to longer-range versions of existing models. From the program’s start, Boeing had considered building ultra-long-range variants. By February 2015, the backlog of undelivered 777s totaled 278 aircraft, equivalent to nearly three years at the then production rate of 8.3 aircraft per month, causing Boeing to ponder the 2018–2020 time frame.

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.

The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. Optional priced features allow operators to accommodate more seats for more revenue and further improve fuel efficiency per seat. And, GE90-115BL engines feature carbon composite, swept fan blades and are considered the world’s most powerful jet engines, producing 115,300 pounds (512 kN) of thrust. The industry-leading flight deck features flat-panel displays that present flight information in a readily accessible form, allowing pilots to quickly optimize flight parameters for schedule, passenger comfort and economy. By moving crew and attendant quarters off the main deck, operators can free as many as four to seven revenue passenger seats, or room for up to six LD-3 containers. Open and spacious, the 777 has a wider cabin and larger windows than any competing airplane.

Production

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 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.

The 777 was the first aircraft to be designed entirely by using a computer. For the design of the 777, Boeing employed a “working together” concept, with input from eight major world airlines in the design process. Boeing recommended suspending flights of all 128 operational 777s equipped with Pratt & Whitney PW4000 engines until they had been inspected. As the undercarriage was in the process of being retracted, the aircraft landed on its rear underbody and engine nacelles, resulting in the separation of one engine, loss of control and subsequent crash. US officials believe the most likely explanation to be that someone in the cockpit of Flight 370 re-programmed the aircraft’s autopilot to travel south across the Indian Ocean. The accident was attributed to ice crystals suspended in the aircraft’s fuel clogging the fuel-oil heat exchanger (FOHE).
