118-400: The Boeing 767 is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes . The aircraft was launched as the 7X7 program on July 14, 1978, the prototype first flew on September 26, 1981, and it was certified on July 30, 1982. The initial 767-200 variant entered service on September 8, 1982, with United Airlines , and the extended-range 767-200ER in 1984. It

236-529: A Lockheed L-1011 TriStar on the route between Boston and Paris, a huge savings. The Airbus A310 secured approval for 120-minute ETOPS flights one month later in June. The larger safety margins were permitted because of the improved reliability demonstrated by twinjets and their turbofan engines. The FAA lengthened the ETOPS time to 180 minutes for CF6-powered 767s in 1989, making the type the first to be certified under

354-414: A short take-off and landing airliner intended for short-distance flights, but customers were unenthusiastic about the concept, leading to its redefinition as a mid-size, transcontinental-range airliner. At this stage the proposed aircraft featured two or three engines, with possible configurations including over-wing engines and a T-tail . By 1976, a twinjet layout, similar to the one which had debuted on

472-467: A 50-foot (15 meters) obstacle within 1,500 feet (450 meters) of commencing takeoff or in landing, to stop within 1,500 feet (450 meters) after passing over a 50-foot (15 meters) obstacle. Also called STOL. STOL (Short Take Off and Landing). STOL performance of an aircraft is the ability of aircraft to take off and clear a 50-foot obstruction in a distance of 1,500 feet from beginning the takeoff run. It must also be able to stop within 1,500 feet after crossing

590-443: A 50-foot obstacle on landing. An aircraft that, at some weight within its approved operating weight, is capable of operating from a STOL runway in compliance with the applicable STOL characteristics and airworthiness, operations, noise, and pollution standards" and ""aircraft" means any machine capable of deriving support in the atmosphere A STOL aircraft is an aircraft with a certified performance capability to execute approaches along

708-467: A 50-ft (15-m) obstacle at the end of that distance and upon landing can clear the same obstacle and then land within 1,000 ft. The STOL mode of flight is one during which an airplane taking off or landing is operated at climb-out and approach speeds lower than the conventionally accepted margins of airspeed above the power-off stalling speed of the airplane. Additionally, some aircraft manufacturers market their products as STOL without providing evidence that

826-555: A 767-300F order for 27 aircraft to replace its DC-10 freighters, citing the USAF tanker order and Boeing's decision to continue production as contributing factors. FedEx Express agreed to buy 19 more of the −300F variant in June 2012. In June 2015, FedEx said it was accelerating retirements of planes both to reflect demand and to modernize its fleet, recording charges of $ 276 million (~$ 347 million in 2023). On July 21, 2015, FedEx announced an order for 50 767-300F with options on another 50,

944-557: A commercial twinjet of 12,082 km (6,524 nmi; 7,507 mi) from Washington, D.C. to Addis Ababa . In the mid-1980s, the 767 and its European rivals, the Airbus A300 and A310 , spearheaded the growth of twinjet flights across the northern Atlantic under extended-range twin-engine operational performance standards ( ETOPS ) regulations, the FAA's safety rules governing transoceanic flights by aircraft with two engines. In 1976,

1062-514: A conventional tail and a supercritical wing for reduced aerodynamic drag . Its two-crew glass cockpit , a first for a Boeing airliner, was developed jointly for the 757 − a narrow-body aircraft , allowing a common pilot type rating . Studies for a higher-capacity 767 in 1986 led Boeing to develop the larger 777 twinjet, introduced in June 1995. The 159-foot-long (48.5 m) 767-200 typically seats 216 passengers over 3,900  nautical miles  [nmi] (7,200 km; 4,500 mi), while

1180-477: A crew of two was safe for operating wide-body jets. A three-crew cockpit remained as an option and was fitted to the first production models. Ansett Australia ordered 767s with three-crew cockpits due to union demands; it was the only airline to operate 767s so configured. The 767's two-crew cockpit was also applied to the 757, allowing pilots to operate both aircraft after a short conversion course, and adding incentive for airlines to purchase both types. To produce

1298-626: A fan diameter of 290 centimetres (116 in), slightly smaller than the GE90 engines on the Boeing 777. The Trent 900 is designed to fit into a Boeing 747-400F freighter for easier transport by air cargo . The interiors of aircraft, known as the aircraft cabin , have been undergoing evolution since the first passenger aircraft. Today, between one and four classes of travel are available on wide-body aircraft. Bar and lounge areas which were once installed on wide-body aircraft have mostly disappeared, but

1416-575: A few have returned in first class or business class on the Airbus A340-600 , Boeing 777-300ER , and on the Airbus A380. Emirates has installed showers for first-class passengers on the A380; twenty-five minutes are allotted for use of the room, and the shower operates for a maximum of five minutes. Depending on how the airline configures the aircraft, the size and seat pitch of

1534-651: A freighter variant, the 767-300F, which entered service with UPS on October 16, 1995. The 767-300F featured a main deck cargo hold, upgraded landing gear, and strengthened wing structure. In November 1993, the Japanese government launched the first 767 military derivative when it placed orders for the E-767 , an Airborne Early Warning and Control (AWACS) variant based on the 767-200ER. The first two E-767s , featuring extensive modifications to accommodate surveillance radar and other monitoring equipment, were delivered in 1998 to

1652-416: A further 787-based cockpit upgrade for the 767, featuring three landscape-format LCD screens that can display two windows each. The 767 is equipped with three redundant hydraulic systems for operation of control surfaces, landing gear, and utility actuation systems. Each engine powers a separate hydraulic system, and the third system uses electric pumps. A ram air turbine provides power for basic controls in

1770-470: A glideslope of 6 degrees or steeper and to execute missed approaches at a climb gradient sufficient to clear a 15:1 missed approach surface at sea level... A STOL runway is one which is specifically designated and marked for STOL aircraft operations, and designed and maintained to specified standards. Heavier-than-air craft that cannot take off and land vertically, but can operate within areas substantially more confined than those normally required by aircraft of

1888-432: A new design available, asked for and received another time-limited exemption for just the 767-300 and 767-300ER until 2019 when commercial production was expected to cease. But in 2017, with continual demand for the 767-300F, Boeing asked for another exemption up to the end of 2027, well past the revised production end date. It is noted that while Boeing requested extension of the original exemption from 2016 to 2019 based upon

2006-658: A new jetliner which aimed to fly 15 percent faster while having comparable fuel costs to the 767. The following year, Boeing announced the KC-767 Tanker Transport , a second military derivative of the 767-200ER. Launched with an order in October 2002 from the Italian Air Force , the KC-767 was intended for the dual role of refueling other aircraft and carrying cargo. The Japanese government became

2124-434: A paradigm shift in the airline industry as point-to-point travel gained prominence at the expense of the traditional hub-and-spoke model. In February 1990, the first 767 equipped with Rolls-Royce RB211 turbofans, a 767-300, was delivered to British Airways . Six months later, the carrier temporarily grounded its entire 767 fleet after discovering cracks in the engine pylons of several aircraft. The cracks were related to

2242-449: A passenger 767-300ER production to bridge the gap. A demand for 50 to 60 aircraft could have to be satisfied. Having to replace its 40 767s, United Airlines requested a price quote for other widebodies. In November 2017, Boeing CEO Dennis Muilenburg cited interest beyond military and freighter uses. However, in early 2018 Boeing Commercial Airplanes VP of marketing Randy Tinseth stated that the company did not intend to resume production of

2360-427: A recovering global economy and ETOPS approval, 767 sales accelerated in the mid-to-late 1980s; 1989 was the most prolific year with 132 firm orders. By the early 1990s, the wide-body twinjet had become its manufacturer's annual best-selling aircraft, despite a slight decrease due to economic recession. During this period, the 767 became the most common airliner for transatlantic flights between North America and Europe. By

2478-423: A retractable tailskid . All passenger 767 models have exit doors near the front and rear of the aircraft. Most 767-200 and -200ER models have one overwing exit door for emergency use; an optional second overwing exit increases maximum allowable capacity from 255 to 290. The 767-300 and -300ER typically feature two overwing exit doors or, in a configuration with no overwing exits, three exit doors on each side and

2596-602: A second aisle, the wider aircraft could accommodate as many as 10 seats across, but could also be easily converted to a freighter and carry two eight-by-eight freight pallets abreast. The engineers also opted for creating "stretched" versions of the DC-8 (61, 62 and 63 models), as well as longer versions of Boeing's 707 (-320B and 320C models) and 727 (-200 model); and Douglas' DC-9 (-30, -40, and -50 models), all of which were capable of accommodating more seats than their shorter predecessor versions. The wide-body age began in 1970 with

2714-458: A similar numbering scheme, but adds a preceding manufacturer letter; all variants based on the 767-200 and 767-300 are classified under the codes "B762" and "B763"; the 767-400ER receives the designation of "B764". The 767-200 was the original model and entered service with United Airlines in 1982. The type has been used primarily by mainline U.S. carriers for domestic routes between major hub centers such as Los Angeles to Washington. The 767-200

2832-423: A smaller exit door aft of the wing. A further configuration featuring three exit doors on each side plus one overwing exit allows an increase in maximum capacity from 290 to 351. All 767-400ERs are configured with three exit doors on each side and a smaller exit door aft of the wing. The 767-300F has one exit door at the forward left-hand side of the aircraft. In addition to shared avionics and computer technology,

2950-480: A third of the 767's design drawings, and performed 26,000 hours of wind tunnel tests. Design work occurred concurrently with the 757 twinjet, leading Boeing to treat both as almost one program to reduce risk and cost. Both aircraft would ultimately receive shared design features, including avionics , flight management systems , instruments, and handling characteristics. Combined development costs were estimated at $ 3.5 to $ 4 billion. Early 767 customers were given

3068-504: A twinjet. Most modern wide-body aircraft have two engines, although the heaviest wide-body aircraft, the Airbus A380 and the Boeing 747-8, are built with four engines. The upcoming Boeing 777X-9 twinjet is approaching the capacity of the earlier Boeing 747. The Boeing 777 twinjet features the most powerful jet engine, the General Electric GE90 . The early variants have a fan diameter of 312 centimetres (123 in), and

3186-562: A typical narrow-body aircraft has a diameter of 3 to 4 m (10 to 13 ft), with a single aisle, and seats between two and six people abreast. Wide-body aircraft were originally designed for a combination of efficiency and passenger comfort and to increase the amount of cargo space. However, airlines quickly gave in to economic factors, and reduced the extra passenger space in order to insert more seats and increase revenue and profits. Wide-body aircraft are also used by commercial cargo airlines , along with other specialized uses. By

3304-538: A window or aisle. As a result, the aircraft can be largely occupied before center seats need to be filled, and each passenger is no more than one seat from the aisle. It is possible to configure the aircraft with extra seats for up to an eight abreast configuration, but this is less common. The 767 interior introduced larger overhead bins and more lavatories per passenger than previous aircraft. The bins are wider to accommodate garment bags without folding, and strengthened for heavier carry-on items. A single, large galley

3422-476: Is a conventional fixed-wing aircraft that has short runway requirements for takeoff and landing . Many STOL-designed aircraft also feature various arrangements for use on airstrips with harsh conditions (such as high altitude or ice). STOL aircraft, including those used in scheduled passenger airline operations, have also been operated from STOLport airfields which feature short runways. Many fixed-wing STOL aircraft are bush planes , though some, like

3540-438: Is a function of the square of the minimum flying speed ( stall speed ), and most design effort is spent on reducing this number. For takeoff , large power/weight ratios and low drag help the plane to accelerate for flight. The landing run is minimized by strong brakes , low landing speed, thrust reversers or spoilers (less common). Overall STOL performance is set by the length of runway needed to land or take off, whichever

3658-679: Is critical, because many small, isolated communities rely on STOL aircraft as their only transportation link to the outside world for passengers or cargo; examples include many communities in the Canadian north and Alaska . Most STOL aircraft can land either on- or off-airport. Typical off-airport landing areas include snow or ice (using skis), fields or gravel riverbanks (often using special fat, low-pressure tundra tires ), and water (using floats ): these areas are often extremely short and obstructed by tall trees or hills. Wheel skis and amphibious floats combine wheels with skis or floats, allowing

3776-425: Is equipped with six-panel leading edge slats , single- and double-slotted flaps , inboard and outboard ailerons , and six spoilers . The airframe further incorporates Carbon-fiber-reinforced polymer composite material wing surfaces, Kevlar fairings and access panels, plus improved aluminum alloys , which together reduce overall weight by 1,900 pounds (860 kg) versus preceding aircraft. To distribute

3894-480: Is installed near the aft doors, allowing for more efficient meal service and simpler ground resupply. Passenger and service doors are an overhead plug type, which retract upwards, and commonly used doors can be equipped with an electric-assist system. In 2000, a 777-style interior, known as the Boeing Signature Interior, debuted on the 767-400ER. Subsequently, adopted for all new-build 767s,

4012-436: Is longer. Of equal importance to short ground run is the ability to clear obstacles, such as hills, on both take off and landing. For takeoff, large power/weight ratios and low drag result in a high rate of climb required to clear obstacles. For landing, high drag allows the aeroplane to descend steeply to the runway without building excess speed resulting in a longer ground run. Drag is increased by use of flaps (devices on

4130-407: Is the main target, but a passenger version could be a cheaper alternative to the proposed New Midsize Airplane . The 767 is a low-wing cantilever monoplane with a conventional tail unit featuring a single fin and rudder. The wings are swept at 31.5 degrees and optimized for a cruising speed of Mach 0.8 (533 mph or 858 km/h). Each wing features a supercritical airfoil cross-section and

4248-626: The Airbus A300 , became the baseline configuration. The decision to use two engines reflected increased industry confidence in the reliability and economics of new-generation jet powerplants. While airline requirements for new wide-body aircraft remained ambiguous, the 7X7 was generally focused on mid-size, high-density markets. As such, it was intended to transport large numbers of passengers between major cities. Advancements in civil aerospace technology, including high-bypass-ratio turbofan engines, new flight deck systems, aerodynamic improvements, and more efficient lightweight designs were to be applied to

4366-725: The Boeing 787 Dreamliner and Airbus A350 XWB . The proposed Comac C929 and C939 may also share this new wide-body market. The production of the large Boeing 747-8 and Airbus A380 four-engine, long-haul jets has come to an end as airlines are now preferring the smaller, more efficient Airbus A350, Boeing 787 and Boeing 777 twin-engine, long-range airliners. Although wide-body aircraft have larger frontal areas (and thus greater form drag ) than narrow-body aircraft of similar capacity, they have several advantages over their narrow-body counterparts, such as: British and Russian designers had proposed wide-body aircraft similar in configuration to

4484-668: The Boeing Yellowstone Project . Customers embraced the 7E7, later renamed 787 Dreamliner, and within two years it had become the fastest-selling airliner in the company's history. In 2005, Boeing opted to continue 767 production despite record Dreamliner sales, citing a need to provide customers waiting for the 787 with a more readily available option. Subsequently, the 767-300ER was offered to customers affected by 787 delays, including All Nippon Airways and Japan Airlines. Some aging 767s, exceeding 20 years in age, were also kept in service past planned retirement dates due to

4602-554: The Japan Self-Defense Forces . The longest flight for the -400ER variant was completed by OMD275 of Nomadic Aviation from Bogota to Abu Dubai in the UAE on May 31, 2024. In November 1995, after abandoning development of a smaller version of the 777, Boeing announced that it was revisiting studies for a larger 767. The proposed 767-400X, a second stretch of the aircraft, offered a 12 percent capacity increase versus

4720-728: The President of the United States . Some wide-body aircraft have been modified to enable transport of oversize cargo . Examples include the Airbus Beluga , Airbus BelugaXL and Boeing Dreamlifter . Two specially modified Boeing 747s were used to transport the U.S. Space Shuttle , while the Antonov An-225 was initially built to carry the Buran shuttle .

4838-626: The United States that were used for scheduled passenger airline operations but are now no longer in existence. Cruise -efficient short takeoff and landing (CESTOL), is an aircraft with both very short runway requirements and high cruise speeds (greater than Mach 0.8). Many different definitions of STOL have been used by different authorities and nations at various times and for a myriad of regulatory and military purposes. Some accepted definitions of STOL include: short takeoff and landing: ( DOD / NATO ) The ability of an aircraft to clear

4956-681: The United States , it is a requirement to suffix the aircraft's call sign with the word heavy (or super ) when communicating with air traffic control in certain areas. Wide-body aircraft are used in science, research, and the military. Some wide-body aircraft are used as flying command posts by the military like the Ilyushin Il-80 or the Boeing E-4 , while the Boeing E-767 is used for airborne early warning and control . New military weapons are tested aboard wide-bodies, as in

5074-567: The Vickers VC10 and Douglas DC-9 , but with a wide-body fuselage. The British BAC Three-Eleven project did not proceed due to lack of government backing, while the Russian Ilyushin Il-86 wide-body proposal eventually gave way to a more conventional wing-mounted engine design, most likely due to the inefficiencies of mounting such large engines on the aft fuselage. As jet engine power and reliability have increased over

5192-411: The airline seats will vary significantly. For example, aircraft scheduled for shorter flights are often configured at a higher seat density than long-haul aircraft. Due to current economic pressures on the airline industry, high seating densities in the economy class cabin are likely to continue. In some of the largest single-deck wide-body aircraft, such as the Boeing 777, the extra space above

5310-670: The de Havilland Canada Dash-7 , are designed for use on prepared airstrips; likewise, many STOL aircraft are taildraggers , though there are exceptions like the PAC P-750 XSTOL , the Quest Kodiak , the de Havilland Canada DHC-6 Twin Otter and the Peterson 260SE . Autogyros also have STOL capability, needing a short ground roll to get airborne, but capable of a near-zero ground roll when landing. Runway length requirement

5428-561: The wake turbulence they produce. Because wake turbulence is generally related to the weight of an aircraft, these categories are based on one of four weight categories: light, medium, heavy, and super. Due to their weight, all current wide-body aircraft are categorized as " heavy ", or in the case of the A380 in U.S. airspace, "super". The wake-turbulence category also is used to guide the separation of aircraft. Super- and heavy-category aircraft require greater separation behind them than those in other categories. In some countries, such as

5546-415: The 1,000th 767 rolled out, destined for All Nippon Airways. The aircraft was the 91st 767-300ER ordered by the Japanese carrier, and with its completion the 767 became the second wide-body airliner to reach the thousand-unit milestone after the 747. The 1,000th aircraft also marked the last model produced on the original 767 assembly line. Beginning with the 1,001st aircraft, production moved to another area in

5664-499: The 1960s, it was also believed that supersonic airliners would succeed larger, slower planes. Thus, it was believed that most subsonic aircraft would become obsolete for passenger travel and would be eventually converted to freighters. As a result, airline manufacturers opted for a wider fuselage rather than a taller one (the 747 , and eventually the McDonnell Douglas DC-10 and Lockheed L-1011 TriStar ). By adding

5782-585: The 201.3-foot-long (61.37 m) 767-400ER typically seats 245 passengers over 5,625 nmi (10,415 km; 6,473 mi). Military derivatives include the E-767 for surveillance and the KC-767 and KC-46 aerial tankers . Initially marketed for transcontinental routes , a loosening of ETOPS rules starting in 1985 allowed the aircraft to operate transatlantic flights . A total of 742 of these aircraft were in service in July 2018, with Delta Air Lines being

5900-406: The 707 and DC-8 seated passengers along either side of a single aisle, with no more than six seats per row. Larger aircraft would have to be longer, higher ( double-deck aircraft ), or wider in order to accommodate a greater number of passenger seats. Engineers realized having two decks created difficulties in meeting emergency evacuation regulations with the technology available at that time. During

One of the justification by Boeing: changes to the fuel quantity indication system would require a halt of delivery by three years as production of the 767 model was expected to end shortly. FAA gave the manufacturer three years to have a compliant system while deliveries continued. In 2014, Boeing, without

6136-638: The 767 uses the same auxiliary power unit , electric power systems, and hydraulic parts as the 757. A raised cockpit floor and the same forward cockpit windows result in similar pilot viewing angles. Related design and functionality allows 767 pilots to obtain a common type rating to operate the 757 and share the same seniority roster with pilots of either aircraft. The original 767 flight deck uses six Rockwell Collins CRT screens to display electronic flight instrument system (EFIS) and engine indication and crew alerting system (EICAS) information, allowing pilots to handle monitoring tasks previously performed by

6254-662: The 767, Boeing formed a network of subcontractors which included domestic suppliers and international contributions from Italy's Aeritalia and Japan's CTDC. The wings and cabin floor were produced in-house, while Aeritalia provided control surfaces, Boeing Vertol made the leading edge for the wings, and Boeing Wichita produced the forward fuselage. The CTDC provided multiple assemblies through its constituent companies, namely Fuji Heavy Industries ( wing fairings and gear doors), Kawasaki Heavy Industries (center fuselage), and Mitsubishi Heavy Industries (rear fuselage, doors, and tail). Components were integrated during final assembly at

6372-440: The 767-200 in late 1982, while Air Canada, China Airlines , El Al , and Pacific Western began operating the aircraft in 1983. The aircraft's introduction was relatively smooth, with few operational glitches and greater dispatch reliability than prior jetliners. Following the 1996 in-flight explosion of TWA Flight 800 , the FAA introduced new rules about flammability reduction in 2008. In 2012, Boeing requested an exemption for

6490-400: The 767-200ER seats 181 over a 6,590 nmi (12,200 km; 7,580 mi) range . The 180-foot-long (54.9 m) 767-300 typically seats 269 passengers over 3,900 nmi (7,200 km; 4,500 mi), while the 767-300ER seats 218 over 5,980 nmi (11,070 km; 6,880 mi). The 767-300F can haul 116,000 lb (52.7 t) over 3,225 nmi (6,025 km; 3,711 mi), and

6608-566: The 767-300, and featured an upgraded flight deck, enhanced interior, and greater wingspan. The variant was specifically aimed at Delta Air Lines' pending replacement of its aging Lockheed L-1011 TriStars, and faced competition from the A330-200, a shortened derivative of the Airbus A330. In March 1997, Delta Air Lines launched the 767-400ER when it ordered the type to replace its L-1011 fleet. In October 1997, Continental Airlines also ordered

6726-546: The 767-300F, a production freighter, and conversions of passenger 767-200 and 767-300 models. When referring to different variants, Boeing and airlines often collapse the model number (767) and the variant designator, e.g. –200 or –300, into a truncated form, e.g. "762" or "763". Subsequent to the capacity number, designations may append the range identifier, though -200ER and -300ER are company marketing designations and not certificated as such. The International Civil Aviation Organization (ICAO) aircraft type designator system uses

6844-709: The 767-300F. Renewed freighter interest led Boeing to consider enhanced versions of the 767-200 and 767-300F with increased gross weights, 767-400ER wing extensions, and 777 avionics. Net orders for the 767 declined from 24 in 2008 to just three in 2010. During the same period, operators upgraded aircraft already in service; in 2008, the first 767-300ER retrofitted with blended winglets from Aviation Partners Incorporated debuted with American Airlines. The manufacturer-sanctioned winglets, at 11 feet (3.35 m) in height, improved fuel efficiency by an estimated 6.5 percent. Other carriers including All Nippon Airways and Delta Air Lines also ordered winglet kits. On February 2, 2011,

6962-422: The 767-400ER to replace its McDonnell Douglas DC-10 fleet. The type completed its first flight on October 9, 1999, and entered service with Continental Airlines on September 14, 2000. In the early 2000s, cumulative 767 deliveries approached 900, but new sales declined during an airline industry downturn. In 2001, Boeing dropped plans for a longer-range model, the 767-400ERX, in favor of the proposed Sonic Cruiser ,

7080-419: The 767. Using a conventional tail design also allowed the rear fuselage to be tapered over a shorter section, providing for parallel aisles along the full length of the passenger cabin, and eliminating irregular seat rows toward the rear of the aircraft. The 767 was the first Boeing wide-body to be designed with a two-crew digital glass cockpit. Cathode-ray tube (CRT) color displays and new electronics replaced

7198-444: The 7X7. Many of these features were also included in a parallel development effort for a new mid-size narrow-body airliner, code-named 7N7, which would become the 757. Work on both proposals proceeded through the airline industry upturn in the late 1970s. In January 1978, Boeing announced a major extension of its Everett factory —which was then dedicated to manufacturing the 747—to accommodate its new wide-body family. In February 1978,

In May 1985, the FAA granted its first approval for 120-minute ETOPS flights to the 767, on an individual airline basis starting with TWA, provided that the operator met flight safety criteria. This allowed the aircraft to fly overseas routes at up to two hours' distance from land. The 767 burned 7,000 lb (3.2 t) less fuel per hour than

7434-498: The Boeing 747 was not surpassed until October 2007, when the Airbus A380 entered commercial service with the nickname "Superjumbo". Both the Boeing 747 and Airbus A380 "jumbo jets" have four engines each (quad-jets), but the upcoming Boeing 777X ("mini jumbo jet") is a twinjet. In the mid-2000s, rising oil costs in a post- 9/11 climate caused airlines to look towards newer, more fuel-efficient aircraft. Two such examples are

7552-590: The DC-10-based Tanker 910 and the 747-200 -based Evergreen Supertanker . Some wide-body aircraft are used as VIP transport. To transport those holding the highest offices, Canada uses the Airbus A310 , while Russia uses the Ilyushin Il-96 . Germany replaced its Airbus A310 with an Airbus A340 in spring 2011. Specially-modified Boeing 747-200s ( Boeing VC-25s ) are used to transport

7670-526: The Everett factory which occupied about half of the previous floor space. The new assembly line made room for 787 production and aimed to boost manufacturing efficiency by over twenty percent. At the inauguration of its new assembly line, the 767's order backlog numbered approximately 50, only enough for production to last until 2013. Despite the reduced backlog, Boeing officials expressed optimism that additional orders would be forthcoming. On February 24, 2011,

7788-447: The Everett factory. For expedited production of wing spars , the main structural member of aircraft wings, the Everett factory received robotic machinery to automate the process of drilling holes and inserting fasteners . This method of wing construction expanded on techniques developed for the 747. Final assembly of the first aircraft began in July 1979. The prototype aircraft, registered as N767BA and equipped with JT9D turbofans,

7906-564: The FAA for landings with 980 feet (300 m) minimum visibility in 1984. On the 767-400ER, the cockpit layout is simplified further with six Rockwell Collins liquid crystal display (LCD) screens, and adapted for similarities with the 777 and the Next Generation 737 . To retain operational commonality , the LCD screens can be programmed to display information in the same manner as earlier 767s. In 2012, Boeing and Rockwell Collins launched

8024-575: The Japan Self-Defense Forces. In late 2002, after airlines expressed reservations about its emphasis on speed over cost reduction, Boeing halted development of the Sonic Cruiser. The following year, the manufacturer announced the 7E7, a mid-size 767 successor made from composite materials which promised to be 20 percent more fuel efficient. The new jetliner was the first stage of a replacement aircraft initiative called

8142-453: The NuLook 767 package by Heath Tecna. In its first year, the 767 logged a 96.1 percent dispatch rate, which exceeded the industry average for all-new aircraft. Operators reported generally favorable ratings for the twinjet's sound levels, interior comfort, and economic performance. Resolved issues were minor and included the recalibration of a leading edge sensor to prevent false readings,

8260-598: The Signature Interior features even larger overhead bins, indirect lighting, and sculpted, curved panels. The 767-400ER also received larger windows derived from the 777. Older 767s can be retrofitted with the Signature Interior. Some operators have adopted a simpler modification known as the Enhanced Interior, featuring curved ceiling panels and indirect lighting with minimal modification of cabin architecture, as well as aftermarket modifications such as

8378-457: The US only. Boeing is widely expected to begin production of 787 Freighter during that extension period. After the debut of the first stretched 767s, Boeing sought to address airline requests for greater capacity by proposing larger models, including a partial double-deck version informally named the "Hunchback of Mukilteo" (from a town near Boeing's Everett factory) with a 757 body section mounted over

8496-547: The USAF announced its selection of the KC-767 Advanced Tanker, an upgraded variant of the KC-767, for its KC-X fleet renewal program. The selection followed two rounds of tanker competition between Boeing and Airbus parent EADS , and came eight years after the USAF's original 2003 announcement of its plan to lease KC-767s. The tanker order encompassed 179 aircraft and was expected to sustain 767 production past 2013. In December 2011, FedEx Express announced

8614-424: The aft main fuselage. In 1986, Boeing proposed the 767-X, a revised model with extended wings and a wider cabin, but received little interest. The 767-X did not get enough interest from airlines to launch and the model was shelved in 1988 in favor of the Boeing 777 . In March 2000, Boeing was to launch the 259-seat 767-400ERX with an initial order for three from Kenya Airways with deliveries planned for 2004, as it

8732-662: The aircraft to Aeroflot. However, in 1976 the Soviet Union launched its own first four-engined wide-body, the Ilyushin Il-86 . After the success of the early wide-body aircraft, several subsequent designs came to market over the next two decades, including the Boeing 767 and 777 , the Airbus A330 and Airbus A340 , and the McDonnell Douglas MD-11 . In the "jumbo" category, the capacity of

8850-465: The aircraft's weight on the ground, the 767 has a retractable tricycle landing gear with four wheels on each main gear and two for the nose gear. The original wing and gear design accommodated the stretched 767-300 without major changes. The 767-400ER features a larger, more widely spaced main gear with 777 wheels, tires, and brakes. To prevent damage if the tail section contacts the runway surface during takeoff, 767-300 and 767-400ER models are fitted with

8968-417: The cabin is used for crew rest areas and galley storage. The term "jumbo jet" usually refers to the largest variants of wide-body airliners; examples include the Boeing 747 (the first wide-body and original "jumbo jet"), Airbus A380 ("superjumbo jet"), and Boeing 777-9 . The phrase "jumbo jet" derives from Jumbo , a circus elephant in the 19th century. Aircraft are categorized by ICAO according to

9086-572: The choice of Pratt & Whitney JT9D or General Electric CF6 turbofans, marking the first time that Boeing had offered more than one engine option at the launch of a new airliner. Both jet engine models had a maximum output of 48,000 pounds-force (210 kN) of thrust . The engines were mounted approximately one-third the length of the wing from the fuselage, similar to previous wide-body trijets. The larger wings were designed using an aft-loaded shape which reduced aerodynamic drag and distributed lift more evenly across their surface span than any of

9204-471: The choice of landing on snow/water or a prepared runway. A number of aircraft modification companies offer STOL kits for improving short-field performance. A STOLport is an airport designed with STOL operations in mind, normally having a short single runway. STOLports are not common but can be found, for example, at London City Airport in London , United Kingdom . There were also several STOLports in

9322-407: The core, then the engines may be shipped on a Boeing 747 Freighter. The General Electric GE9X , powering the Boeing 777X, is wider than the GE90 by 15 centimetres (6 in). The 560 tonnes (1,230,000 lb) maximum takeoff weight of the Airbus A380 would not have been possible without the engine technology developed for the Boeing 777 such as contra-rotating spools. Its Trent 900 engine has

9440-486: The cost of upgrading the design and their low production rate and ending production in 2019, Boeing developed the KC-46 tanker (based on the 767) which fully compliant with the new rulings and is assembled on the same production line as the 767. Since the 2019 exemption went into effect, Boeing has increased production of the freighter to satisfy demand. Forecasting airline interest in larger-capacity models, Boeing announced

9558-413: The delays. To extend the operational lives of older aircraft, airlines increased heavy maintenance procedures, including D-check teardowns and inspections for corrosion , a recurring issue on aging 767s. The first 787s entered service with All Nippon Airways in October 2011, 42 months behind schedule. In 2007, the 767 received a production boost when UPS and DHL Aviation placed a combined 33 orders for

9676-475: The end of 2017, nearly 8,800 wide-body airplanes had been delivered since 1969, with production peaking at 412 in 2015. Following the success of the Boeing 707 and Douglas DC-8 in the late 1950s and early 1960s, airlines began seeking larger aircraft to meet the rising global demand for air travel. Engineers were faced with many challenges as airlines demanded more passenger seats per aircraft, longer ranges and lower operating costs. Early jet aircraft such as

9794-551: The end of the decade, 767s crossed the Atlantic more frequently than all other aircraft types combined. The 767 also propelled the growth of point-to-point flights which bypassed major airline hubs in favor of direct routes . Taking advantage of the aircraft's lower operating costs and smaller capacity, operators added non-stop flights to secondary population centers, thereby eliminating the need for connecting flights. The increased number of cities receiving non-stop services caused

9912-622: The entry into service of the first wide-body airliner, the four-engined, partial double-deck Boeing 747 . New trijet wide-body aircraft soon followed, including the McDonnell Douglas DC-10 and the L-1011 TriStar. The first wide-body twinjet , the Airbus A300 , entered service in 1974. This period came to be known as the "wide-body wars". L-1011 TriStars were demonstrated in the USSR in 1974, as Lockheed sought to sell

10030-496: The event of an emergency. An early form of fly-by-wire is employed for spoiler operation, utilizing electric signaling instead of traditional control cables. The fly-by-wire system reduces weight and allows independent operation of individual spoilers. The 767 features a twin-aisle cabin with a typical configuration of six abreast in business class and seven across in economy . The standard seven abreast, 2–3–2 economy class layout places approximately 87 percent of all seats at

10148-412: The extended-range model could carry heavier payloads at distances up to 6,385 nautical miles (11,825 km; 7,348 mi), and was targeted at overseas customers. The 767-200ER entered service with El Al Airline on March 27, 1984. The type was mainly ordered by international airlines operating medium-traffic, long-distance flights. In May 1984, an Ethiopian Airlines 767-200ER set a non-stop record for

10266-536: The extra weight of the RB211 engines, which are 2,205 pounds (1,000 kg) heavier than other 767 engines. During the grounding, interim repairs were conducted to alleviate stress on engine pylon components, and a parts redesign in 1991 prevented further cracks. Boeing also performed a structural reassessment, resulting in production changes and modifications to the engine pylons of all 767s in service. In January 1993, following an order from UPS Airlines , Boeing launched

10384-523: The first delivery to Delta Air Lines on October 25, 1982. The 767 entered service with United Airlines on September 8, 1982. The aircraft's first commercial flight used a JT9D-powered 767-200 on the Chicago-to-Denver route. The CF6-powered 767-200 commenced service three months later with Delta Air Lines. Upon delivery, early 767s were mainly deployed on domestic routes, including US transcontinental services. American Airlines and TWA began flying

10502-454: The first wide-body jetliner with a fuselage wide enough to feature a twin-aisle cabin. Two years later, the manufacturer began a development study, code-named 7X7, for a new wide-body jetliner intended to replace the 707 and other early generation narrow-body airliners. The aircraft would also provide twin-aisle seating, but in a smaller fuselage than the existing 747, McDonnell Douglas DC-10 , and Lockheed L-1011 TriStar wide-bodies. To defray

10620-414: The flight engineer. The CRTs replace conventional electromechanical instruments found on earlier aircraft. An enhanced flight management system, improved over versions used on early 747s, automates navigation and other functions, while an automatic landing system facilitates CAT IIIb instrument landings in low visibility situations. The 767 became the first aircraft to receive CAT IIIb certification from

10738-558: The high cost of development, Boeing signed risk-sharing agreements with Italian corporation Aeritalia and the Civil Transport Development Corporation (CTDC), a consortium of Japanese aerospace companies. This marked the manufacturer's first major international joint venture, and both Aeritalia and the CTDC received supply contracts in return for their early participation. The initial 7X7 was conceived as

10856-530: The horizontal tail. The 767-400ERX would offer the capacity of the Airbus A330-200 with 3% lower fuel burn and costs. Boeing cancelled the variant development in 2001. Kenya Airways then switched its order to the 777-200ER. In October 2019, Boeing was reportedly studying a re-engined 767-XF for entry into service around 2025, based on the 767-400ER with an extended landing gear to accommodate larger General Electric GEnx turbofan engines. The cargo market

10974-426: The inability to retract the landing gear because of a hydraulic fluid leak. The prototype was used for subsequent flight tests. The 10-month 767 flight test program utilized the first six aircraft built. The first four aircraft were equipped with JT9D engines, while the fifth and sixth were fitted with CF6 engines. The test fleet was largely used to evaluate avionics, flight systems, handling, and performance, while

11092-463: The larger GE90-115B has a fan diameter of 325 centimetres (128 in). This is almost as wide as the 3.30 metres (130 in) Fokker 100 fuselage. Complete GE90 engines can only be ferried by outsize cargo aircraft such as the Antonov An-124 , presenting logistics problems if a 777 is stranded in a place due to emergency diversions without the proper spare parts. If the fan is removed from

11210-406: The largest operator with 77 aircraft in its fleet. As of October 2024, Boeing has received 1,407 orders from 74 customers, of which 1,319 airplanes have been delivered, while the remaining orders are for cargo or tanker variants. Competitors have included the Airbus A300 , A310 , and A330-200 . Its successor, the 787 Dreamliner , entered service in 2011. In 1970, the 747 entered service as

11328-496: The largest order for the type. With the announcement FedEx confirmed that it has firm orders for 106 of the freighters for delivery between 2018 and 2023. In February 2018, UPS announced an order for 4 more 767-300Fs to increase the total on order to 63. With its successor, the Boeing New Midsize Airplane , that was planned for introduction in 2025 or later, and the 787 being much larger, Boeing could restart

11446-475: The laser weapons testing on the Boeing YAL-1 . Other wide-body aircraft are used as flying research stations, such as the joint German–U.S. Stratospheric Observatory for Infrared Astronomy (SOFIA). Airbus A340, Airbus A380, and Boeing 747 four-engine wide-body aircraft are used to test new generations of aircraft engines in flight. A few aircraft have also been converted for aerial firefighting , such as

11564-493: The last decades, most of the wide-body aircraft built today have only two engines. A twinjet design is more fuel-efficient than a trijet or quadjet of similar size. The increased reliability of modern jet engines also allows aircraft to meet the ETOPS certification standard, which calculates reasonable safety margins for flights across oceans. The trijet design was dismissed due to higher maintenance and fuel costs compared to

11682-439: The longer duration, and all available engines received approval by 1993. Regulatory approval spurred the expansion of transoceanic flights with twinjet aircraft and boosted the sales of both the 767 and its rivals. The 767 has been produced in three fuselage lengths. These debuted in progressively larger form as the 767-200, 767-300, and 767-400ER. Longer-range variants include the 767-200ER and 767-300ER, while cargo models include

11800-685: The longer-range -400ERX would have a strengthened wing, fuselage and landing gear for a 15,000 lb (6.8 t) higher MTOW , up to 465,000 lb (210.92 t). Thrust would rise to 72,000 lbf (320 kN) for better takeoff performance, with the Trent 600 or the General Electric/Pratt & Whitney Engine Alliance GP7172, also offered on the 747X. Range would increase by 525 nmi (950 km; 604 mi) to 6,150 nmi (11,390 km; 7,080 mi), with an additional fuel tank of 2,145 U.S. gallons (8,120 L) in

11918-407: The manufacturer's previous aircraft. The wings provided higher-altitude cruise performance, added fuel capacity, and expansion room for future stretched variants. The initial 767-200 was designed for sufficient range to fly across North America or across the northern Atlantic, and would be capable of operating routes up to 3,850 nautical miles (7,130 km; 4,430 mi). The 767's fuselage width

12036-509: The new jetliner received the 767 model designation, and three variants were planned: a 767-100 with 190 seats, a 767-200 with 210 seats, and a trijet 767MR/LR version with 200 seats intended for intercontinental routes. The 767MR/LR was subsequently renamed 777 for differentiation purposes. The 767 was officially launched on July 14, 1978, when United Airlines ordered 30 of the 767-200 variant, followed by 50 more 767-200 orders from American Airlines and Delta Air Lines later that year. The 767-100

12154-538: The passenger variant. In its first quarter of 2018 earnings report, Boeing plans to increase its production from 2.5 to 3 monthly beginning in January 2020 due to increased demand in the cargo market, as FedEx had 56 on order, UPS has four, and an unidentified customer has three on order. This rate could rise to 3.5 per month in July 2020 and 4 per month in January 2021, before decreasing to 3 per month in January 2025 and then 2 per month in July 2025. In 2019, unit cost

12272-468: The replacement of an evacuation slide latch, and the repair of a tailplane pivot to match production specifications. Seeking to capitalize on its new wide-body's potential for growth, Boeing offered an extended-range model, the 767-200ER, in its first year of service. Ethiopian Airlines placed the first order for the type in December 1982. Featuring increased gross weight and greater fuel capacity,

12390-401: The role of the flight engineer by enabling the pilot and co-pilot to monitor aircraft systems directly. Despite the promise of reduced crew costs, United Airlines initially demanded a conventional three-person cockpit, citing concerns about the risks associated with introducing a new aircraft. The carrier maintained this position until July 1981, when a US presidential task force determined that

12508-462: The same size. Derived from short takeoff and landing aircraft. short takeoff and landing aircraft (STOL), heavier-than-air craft, capable of rising from and descending to the ground with only a short length of runway, but incapable of doing so vertically. The precise definition of an STOL aircraft has not been universally agreed upon. However, it has been tentatively defined as an aircraft that upon taking off needs only 1,000 ft (305 m) of runway to clear

12626-634: The second customer for the type in March 2003. In May 2003, the United States Air Force (USAF) announced its intent to lease KC-767s to replace its aging KC-135 tankers. The plan was suspended in March 2004 amid a conflict of interest scandal , resulting in multiple US government investigations and the departure of several Boeing officials, including Philip Condit , the company's chief executive officer , and chief financial officer Michael Sears. The first KC-767s were delivered in 2008 to

12744-848: The sixth aircraft was used for route-proving flights. During testing, pilots described the 767 as generally easy to fly, with its maneuverability unencumbered by the bulkiness associated with larger wide-body jets. Following 1,600 hours of flight tests, the JT9D-powered 767-200 received certification from the US Federal Aviation Administration (FAA) and the UK Civil Aviation Authority (CAA) in July 1982. The first delivery occurred on August 19, 1982, to United Airlines. The CF6-powered 767-200 received certification in September 1982, followed by

12862-519: The stretched 767-300 in 1983 and the extended-range 767-300ER in 1984. Both models offered a 20 percent passenger capacity increase, while the extended-range version was capable of operating flights up to 5,990 nautical miles (11,090 km; 6,890 mi). Japan Airlines placed the first order for the -300 in September 1983. Following its first flight on January 30, 1986, the type entered service with Japan Airlines on October 20, 1986. The 767-300ER completed its first flight on December 9, 1986, but it

12980-433: The wings) and by a forward slip (causing the aeroplane to fly somewhat sideways through the air to increase drag). Normally, a STOL aircraft will have a large wing for its weight. These wings often use aerodynamic devices like flaps, slots , slats , and vortex generators . Typically, designing an aircraft for excellent STOL performance reduces maximum speed, but does not reduce payload lifting ability. The payload

13098-501: Was US$ 217.9 million for a -300ER, and US$ 220.3 million for a -300F. Production of the 767 was expected to cease by the end of 2027 due to more stringent emissions and noise limits that will go into effect in 2028. However, as of May 2024, the US Congress is considering giving Boeing a waiver to continue to produce the 767 freighter for an additional five years. If granted, these aircraft would be restricted to domestic use within

13216-415: Was not until March 1987 that the first firm order, from American Airlines, was placed. The type entered service with American Airlines on March 3, 1988. The 767-300 and 767-300ER gained popularity after entering service, and came to account for approximately two-thirds of all 767s sold. Until the 777's 1995 debut, the 767-300 and 767-300ER remained Boeing's second-largest wide-bodies behind the 747. Buoyed by

13334-407: Was proposed to Lauda Air . Increased gross weight and a tailplane fuel tank would have boosted its range by 11,100 to 12,025 km (5,990 to 6,490 nmi; 6,900 to 7,470 mi), and GE could offer its 65,000–68,000 lbf (290–300 kN) CF6 -80C2/G2. Rolls-Royce offered its 68,000–72,000 lbf (300–320 kN) Trent 600 for the 767-400ERX and the Boeing 747X . Offered in July,

13452-427: Was rolled out on August 4, 1981. By this time, the 767 program had accumulated 173 firm orders from 17 customers, including Air Canada , All Nippon Airways , Britannia Airways , Transbrasil , and Trans World Airlines (TWA). On September 26, 1981, the prototype took its maiden flight under the command of company test pilots Tommy Edmonds, Lew Wallick, and John Brit. The maiden flight was largely uneventful, save for

13570-462: Was set midway between that of the 707 and the 747 at 16.5 feet (5.03 m). While it was narrower than previous wide-body designs, seven abreast seating with two aisles could be fitted, and the reduced width produced less aerodynamic drag. The fuselage was not wide enough to accommodate two standard LD3 wide-body unit load devices side-by-side, so a smaller container, the LD2, was created specifically for

13688-609: Was stretched into the 767-300 in October 1986, followed by the extended-range 767-300ER in 1988, the most popular variant. The 767-300F, a production freighter version, debuted in October 1995. It was stretched again into the 767-400ER from September 2000. Designed to complement the larger 747 , it has a seven-abreast cross-section accommodating smaller LD2 ULD cargo containers. The 767 is Boeing's first wide-body twinjet , powered by General Electric CF6 , Rolls-Royce RB211 , or Pratt & Whitney JT9D turbofans. JT9D engines were eventually replaced by PW4000 engines. The aircraft has

13806-475: Was the first aircraft to be used on transatlantic ETOPS flights, beginning with TWA on February 1, 1985, under 90-minute diversion rules. Deliveries for the variant totaled 128 aircraft. There were 52 examples of the model in commercial service as of July 2018, almost entirely as freighter conversions. The type's competitors included the Airbus A300 and A310. Wide-body airliner By comparison,

13924-567: Was ultimately not offered for sale, as its capacity was too close to the 757's seating, while the 777 trijet was eventually dropped in favor of standardizing the twinjet configuration. In the late 1970s, operating cost replaced capacity as the primary factor in airliner purchases. As a result, the 767's design process emphasized fuel efficiency from the outset. Boeing targeted a 20 to 30 percent cost saving over earlier aircraft, mainly through new engine and wing technology. As development progressed, engineers used computer-aided design for over
