[144], The wings on the 777 feature a supercritical airfoil design that is swept back at 31.6 degrees and optimized for cruising at Mach 0.83 (revised after flight tests up to Mach 0.84). [63] 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. [185] It holds the world record for the longest nonstop flight by a commercial airliner. Its operating empty weight with Rolls-Royce engines in typical tri-class layout is 343,300 lb (155.72 t) compared to 307,300 lb (139.38 t) for a similarly configured -200. [111] Program sales accounted for an estimated US$400 million of Boeing's pretax earnings in 2000, US$50 million more than the 747. [190] The 777 was designed to be stretched by 20%: 60 extra seats to almost 370 in tri-class, 75 more to 451 in two classes, or up to 550 in all-economy like the 747SR short-range variant. In 2003, Boeing introduced overhead crew rests as an option on the 777. [241][242] The accident was attributed to ice crystals suspended in the aircraft's fuel clogging the fuel-oil heat exchanger (FOHE). [189], 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. [181][182], The 777-200LR ("LR" for Long Range), the C-market model, entered service in 2006 as one of the longest-range commercial airliners. [163] 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. [101] On November 10, 2005, the first -200LR set a record for the longest non-stop flight of a passenger airliner by flying 11,664 nautical miles (21,602 km) eastward from Hong Kong to London. [51] 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 777 entered service with the launch customer, United Airlines, on June 7, 1995. [200], The first -300ER was delivered to Air France on April 29, 2004. [115] Complete assembly of each 777-300ER requires 49 days. The passengers and crew were deplaned, and the fire was extinguished, but not before causing substantial damage to the aircraft. 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. [132], In tandem with the development of the third generation Boeing 777X, Boeing worked with General Electric to offer a 2% improvement in fuel efficiency to in-production 777-300ER aircraft. With windows plugged, passenger doors deactivated, fuselage and floor reinforced, and a main-deck cargo door installed, the 777-300ERSF has 15% more volume than a 747-400BCF. [102] Lasting 22 hours and 42 minutes, the flight surpassed the -200LR's standard design range and was logged in the Guinness World Records. [61] General Electric subsequently announced engine upgrades. [247][248] Investigators focused on a possible short circuit between an electrical cable and a supply hose in the cockpit crew oxygen system. Max. [47], The production process included substantial international content, an unprecedented level of global subcontracting for a Boeing jetliner,[48] later exceeded by the 787. The aircraft skidded just over 1000 feet, tearing off its landing gear and coming to rest on the tarmac just to the right of the end of the runway. [153] A ram air turbine—a small retractable device which can provide emergency power—is also fitted in the wing root fairing. There were no passengers on either aircraft during the crash. The 777-300ER was to shed 1,800 lb (820 kg) by replacing the fuselage crown with tie rods and composite integration panels, similar to those used on the 787. Boeing's 737 MAX has been grounded for more than 10 months following two devastating crashes. [210], In October 2019, Boeing and Israeli Aerospace Industries (IAI) launched the 777-300ERSF passenger to freighter conversion program with GECAS ordering 15 aircraft and 15 options, the first aftermarket 777 freighter conversion program. Other Continental plane crashes [90] GE was proposing a 454 kN (102,000 lbf) GE90-102B, while P&W offered its 436 kN (98,000 lbf) PW4098 and R-R was proposing a 437 kN (98,000 lbf) Trent 8100. 767, 777, 787, Related information [21] By March 1990, Boeing and the airlines had decided upon a basic design configuration: a cabin cross-section close to the 747's, capacity up to 325 passengers, flexible interiors, a glass cockpit, fly-by-wire controls, and 10 percent better seat-mile costs than the A330 and MD-11. In November 2013, Boeing announced the 777X development with the -8 and -9 variants, scheduled to enter service by 2020. Large 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. [118], A total of 1,416 aircraft (all variants) were in airline service as of July 2018[update], with Emirates (163), United Airlines (91), Air France (70), Cathay Pacific (69), American Airlines (67), Qatar Airways (67), British Airways (58), Korean Air (53), All Nippon Airways (50), Singapore Airlines (46), and other operators with fewer aircraft of the type. French Bee’s is even more dense with its 411 seats A350-900, due to 10-abreast economy seating, reaching a €.04 CASK according to Air France, and lower again with its 480 seats -1000. [12] Emirates is the largest operator of the LR variant with 10 aircraft. The 777 was designed to bridge the gap between Boeing's 767 and 747, and to replace older DC-10s or L-1011s. [16] In 1978, Boeing unveiled three new models: the twin-engine Boeing 757 to replace its 727, the twin-engine 767 to challenge the Airbus A300, and a trijet 777 concept to compete with the DC-10 and L-1011. [35] In January 1993, a team of United developers joined other airline teams and Boeing designers at the Everett factory. In March 2019, the Boeing 737 MAX passenger airliner was grounded worldwide after 346 people died in two crashes, Lion Air Flight 610 on October 29, 2018 and Ethiopian Airlines Flight 302 on March 10, 2019. [168], When referring to different variants, the International Air Transport Association (IATA) code collapses the 777 model designator and the -200 or -300 variant designator to "772" or "773". [146] This capacity allows the 777-200LR to operate ultra-long-distance, trans-polar routes such as Toronto to Hong Kong. [192] Its wings have an aspect ratio of 9.0. [149] Elements made from composite material include the cabin floor and rudder. [123], In November 2013, with orders and commitments totaling 259 aircraft from Lufthansa, Emirates, Qatar Airways, and Etihad Airways, Boeing formally launched the 777X program, the third generation of the 777 (not to be confused with the 777-X variants, which were the second generation of the aircraft), with two models: the 777-8 and 777-9. But the Boeing 777 is considered a staple of major airlines' long-haul fleets and has never been involved in a fatal accident since entering service in June 1995. [37] New production methodologies were developed, including a turn machine that could rotate fuselage subassemblies 180 degrees, giving workers access to upper body sections. At this time, the position of the aircraft was estimated 90 NM northeast of … [14][15], 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 Boeing 777-200ER, registration HL7742, was powered by two Pratt and Whitney PW4090 engines. EgyptAir plane crashes, Other Boeing Models [2] The most common and successful variant is the 777-300ER with 844 aircraft ordered and 810 delivered. [81] With a 658,000 lb (298 t) MTOW and 93,700 lbf (417 kN) engines, it has a 7,065 nmi (13,084 km) range.
