Nine different -200 customers have taken delivery of 88 aircraft, with 55 in airline service as of 2018update. The International Civil Aviation Organization (ICAO) aircraft type designator system adds a preceding manufacturer letter, in this case “B” for Boeing, hence “B772” or “B773”. Each manufacturer agreed to develop an engine in the 77,200–98,000 lbf (343–436 kN) of thrust class for the world’s largest twinjet, resulting in the General Electric GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800 engines. 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. 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.

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. A further program, the ecoDemonstrator series, is intended to test and develop technologies and techniques to reduce aviation’s environmental impact. The first program, the Quiet Technology Demonstrator (QTD) was run in collaboration with Rolls-Royce and General Electric to develop and validate engine intake and exhaust modifications, including the chevrons subsequently used in the 737 MAX, and 787 series. The company has been in discussion with several airline customers, including FedEx Express, UPS Airlines, and GE Capital Aviation Services, to provide launch orders for a 777 BCF program.
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.
Production
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. Smaller folding wingtips of 11 feet (3.35 m) in length will allow 777X models to use the same airport gates and taxiways as earlier 777s.
Boeing developed its high-performance visualization system, FlyThru, later called IVT (Integrated Visualization Tool) to support large-scale collaborative engineering design reviews, production illustrations, and other uses of the CAD data outside of engineering. This allowed engineers to virtually assemble the 777 aircraft on a computer system to check for interference and verify that the thousands of parts fit properly before the actual assembly process—thus reducing costly rework. The 240 design teams, with up to 40 members each, addressed almost 1,500 design issues with individual aircraft components. At the group’s first meeting in January 1990, a 23-page questionnaire was distributed to the airlines, asking what each wanted in the design.
Before you fly
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 vegas casino apk crystals suspended in the aircraft’s fuel clogging the fuel-oil heat exchanger (FOHE).
The airplane is renowned for its Boeing Signature Interior and spacious passenger cabin. Large overhead compartments provide passengers with increased stowage capacity. The airplane’s performance, economics, range capability and payload capacity help operators maximize profits. It can carry hundreds of passengers and still go the distance, thanks to its incredible fuel efficiency. Airlines can arrange the seating to maximize comfort and capacity, making it a favorite for long flights. The 777 is a wide-body jet, meaning it’s designed to fit more passengers comfortably.
A third passenger died six days later as a result of injuries sustained during the crash. Investigators found these were also caused by ice in the fuel clogging the FOHE. 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.
Entry into service
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. By June 1997, orders for the 777 numbered 323 from 25 airlines, including launch customers that had ordered additional aircraft. The first Rolls-Royce Trent 877-powered aircraft was delivered to Thai Airways International on March 31, 1996, completing the introduction of the three power plants initially developed for the airliner. On November 12, 1995, Boeing delivered the first model with General Electric GE90-77B engines to British Airways, which entered service five days later. The first aircraft built was used by Boeing’s nondestructive testing campaign from 1994 to 1996, and provided data for the -200ER and -300 programs.
Variants for the Boeing 777
By the late 2000s, the 777 was facing increased potential competition from Airbus’ planned A350 XWB and internally from proposed 787 series, both airliners that offer fuel efficiency improvements. Lasting 22 hours and 42 minutes, the flight surpassed the -200LR’s standard design range and was logged in the Guinness World Records. 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.
- 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.
- 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.
- 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 first generation of Boeing 777 models, the -200, -200ER, and -300 have since been known collectively as the Boeing 777 Classics. The -300 was awarded type certification simultaneously from the FAA and JAA on May 4, 1998, and entered service with launch customer Cathay Pacific on May 27, 1998. Initial service was affected by gearbox bearing wear issues, which caused British Airways to temporarily withdraw its 777 fleet from transatlantic service in 1997, returning to full service later that year. The first flight took place on June 12, 1994, under the command of chief test pilot John E. Cashman. Each design drawing was created on a three-dimensional CAD software system known as CATIA, sourced from Dassault Systèmes and IBM. 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).
- Seating options range from four to six–abreast in first class up to ten–abreast in economy.
- Developed in consultation with eight major airlines, the 777 program was launched in October 1990, with an order from United Airlines.
- 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.
- The aircraft features the largest landing gear and the biggest tires ever used in a commercial jetliner.
- The first refreshed aircraft are taking off.
Boeing 777: A Game-Changer in Commercial Aviation
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. 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). Room for an additional seat in every row gives airlines the opportunity to boost revenue passenger capacity while maintaining a high level of passenger comfort. 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.
You can also sit back and relax in our refreshed Economy Class cabin. And our already spacious seats are now two inches wider for even more comfort. 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 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.
The airframe incorporates the use of composite materials, accounting for nine percent of the original structural weight, while the third-generation models, the and 777-9, feature more composite parts. In 2013, Boeing announced that the upgraded 777X models would incorporate airframe, systems, and interior technologies from the 787. The first member of the 777X family was projected to enter service in 2020 at the time of the program announcement.

New production methods were developed, including a turn machine that could rotate fuselage subassemblies 180 degrees, giving workers access to upper body sections. 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. The production process included substantial international content, an unprecedented level of global subcontracting for a Boeing jetliner, later exceeded by the 787.
The main purpose has been for VIP transport, including as an air transport for heads of state, although the aircraft has also been proposed for other military applications. The third-generation of the 777, launched as the 777X, is to feature new GE9X engines and new composite wings with folding wingtips. 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.
Launched at the Paris Air Show on June 26, 1995, its major assembly started in March 1997 and its body was joined on July 21, it was rolled-out on September 8 and made its first flight on October 16. Other new features include extended raked wingtips, redesigned main landing gear, and additional structural strengthening. Developed alongside the -300ER, the -200LR features an increased MTOW and three optional auxiliary fuel tanks in the rear cargo hold. Boeing named it Worldliner as it can connect almost any two airports in the world, although it is still subject to ETOPS restrictions. As of 2019update, Boeing no longer markets the -200, as indicated by its removal from the manufacturer’s price listings for 777 variants.
