A twin-engine replacement for the single-engine DHC-3 Otter retaining DHC's renowned STOL qualities, its design features included double-slotted trailing-edge flaps and ailerons that work in unison with the flaps to boost STOL performance. The availability of the Pratt & Whitney Canada PT6A-20 turboprop in the early 1960s made the concept of a twin more feasible. To bush operators, the improved reliability of turboprop power and the improved performance of a twin-engine configuration made it an immediately popular

The first six aircraft produced were designated Series 1, indicating that they were prototype aircraft. The initial production run consisted of Series 100 aircraft, serial numbers seven to 115 inclusive. In 1968, Series 200 production began with serial number 116. Changes made at the beginning of Series 200 production included improving the STOL performance, adding a longer nose that was equipped with a larger baggage compartment (except for aircraft fitted with floats), and fitting a larger door to the rear baggage compartment. All Series 1, 100, and 200 aircraft

In 1969, the Series 300 was introduced, beginning with serial number 231. Both aircraft performance and payload were improved by fitting more powerful PT6A-27 engines. This was a engine that was flat-rated to for use in the Series 300 Twin Otter. The Series 300 proved to be the most successful variant by far, with 614 Series 300 aircraft and their subvariants (Series 310 for United Kingdom operators, Series 320 for Australian operators, etc.) sold before production in Toronto by de Havilland Canada ended in 1988.

After Series 300 production ended, the remaining tooling was purchased by Viking Air of Victoria, British Columbia, which manufactures replacement parts for all of the out-of-production de Havilland Canada aircraft. On February 24, 2006, Viking purchased the type certificates from Bombardier Aerospace for all the out-of-production de Havilland Canada aircraft (DHC-1 through DHC-7). The ownership of the certificates gives Viking the exclusive right to manufacture new aircraft. On July

Many Twin Otters still serve in the far north, but they can also be found in Africa, Australia, Asia, Antarctica, and other regions where bush planes are the optimum means of travel. Their versatility and maneuverability have made them popular in areas with difficult flying environments such as Papua New Guinea. In Norway, the Twin Otter paved the way for the network of short-field airports, connecting rural areas with larger towns. The Twin Otter showed outstanding reliability, and remained in service until 2000

title: "De Havilland Canada DHC-6 Twin Otter" content: on certain routes. Widerøe of Norway was, at one time, the world's largest operator of Twin Otters. During one period of its tenure in Norway, the Twin Otter fleet achieved over 96,000 cycles (take-off, flight, and landing) per year. A number of commuter airlines in the United States got their start by operating Twin Otters in scheduled passenger operations. Houston Metro Airlines (which later changed its name to Metro Airlines) constructed their own STOLport airstrip with a passenger terminal and maintenance hangar in Clear Lake City, Texas, near the NASA Johnson Space Center. The Clear Lake City STOLport was specifically

According to the February 1976 edition of the "Official Airline Guide", Houston Metro operated 22 round-trip flights every weekday at this time between Clear Lake City (CLC) and Houston Intercontinental Airport (IAH, now Houston George Bush Intercontinental Airport) in a scheduled passenger airline shuttle operation. Houston Metro had agreements in place for connecting passenger feed services with Continental Airlines and Eastern Airlines at Houston Intercontinental, with this major airport having a dedicated STOL landing area at the time specifically for Twin Otter flight operations.

The Walt Disney World Airport (DWS), also known as the Lake Buena Vista STOLport, was a private airfield constructed by the Walt Disney Company with Twin Otter operations in mind. In the early 1970s, Shawnee Airlines operated scheduled Twin Otter flights between the Disney resort and nearby Orlando Jetport (MCO, now Orlando International Airport), as well as to Tampa International Airport (TPA).

Another commuter airline in the U.S., Rocky Mountain Airways, operated Twin Otters from the Lake County Airport in Leadville, CO. At an elevation of 9,927 feet above mean sea level, this airport is the highest airfield in the U.S. ever to have received scheduled passenger airline service, thus demonstrating the wide-ranging flight capabilities of the Twin Otter. Rocky Mountain Airways went on to become the worldwide launch customer for the larger, four-engine de Havilland Canada DHC-7 Dash 7 STOL turboprop, but

Larger scheduled passenger airlines based in the United States, Canada, Mexico, the Caribbean and Australia, particularly jetliner operators, also flew Twin Otters, with the aircraft providing connecting feeder service for these airlines. Jet aircraft operators which also flew the Twin Otter included Aeronaves de Mexico, Air BC, Alaska Airlines, ALM Antillean Airlines, Ansett Airlines, Cayman Airways, Frontier Airlines (1950-1986), LIAT, Norcanair, Nordair, Ozark Air Lines, Pacific Western Airlines, Quebecair, South Pacific Island Airways, Time Air, Transair (Canada), Trans Australian Airlines (TAA), Wardair Canada and Wien Air Alaska. In many cases, the excellent

Twin Otters are also a staple of Antarctic transportation. Four Twin Otters are employed by the British Antarctic Survey on research and supply flights, and several are employed by the United States Antarctic Program via contract with Kenn Borek Air. On April 24–25, 2001, two Twin Otters performed the first winter flight to Amundsen–Scott South Pole Station to perform a medical evacuation.

The Argentine Air Force has used the Twin Otter in Antarctica since the 1970s, with at least one of them deployed year-round at Marambio Base. The Chilean Air Force has operated the type since 1980, usually having an example based at Presidente Frei Antarctic base of the South Shetland islands. As of August 2006, a total of 584 Twin Otter aircraft (all variants) remain in service worldwide. Major operators include: Libyan Arab Airlines (16), Maldivian Air Taxi (22), Trans Maldivian Airways (23), Kenn

title: "Memorial to the Murdered Jews of Europe" content: Memorial to the Murdered Jews of Europe The Memorial to the Murdered Jews of Europe (), also known as the Holocaust Memorial (German: "Holocaust-Mahnmal"), is a memorial in Berlin to the Jewish victims of the Holocaust, designed by architect Peter Eisenman and engineer Buro Happold. It consists of a site covered with 2,711 concrete slabs or "stelae", arranged in a grid pattern on a sloping field. The stelae are long, wide and vary in height from . They are organized in rows, 54 of them going north–south, and 87 heading east–west at right angles but set slightly askew. An attached

title: "Memorial to the Murdered Jews of Europe" content: underground "Place of Information" () holds the names of approximately 3 million Jewish Holocaust victims, obtained from the Israeli museum Yad Vashem. Building began on April 1, 2003, and was finished on December 15, 2004. It was inaugurated on May 10, 2005, sixty years after the end of World War II, and opened to the public two days later. It is located one block south of the Brandenburg Gate, in the Mitte neighborhood. The cost of construction was approximately €25 million. The memorial is located on Cora-Berliner-Straße 1, 10117 in Berlin, a city with one of the largest Jewish populations

title: "Memorial to the Murdered Jews of Europe" content: the grey flat stones and the blue sky as a recognition of the "dismal times" of the Holocaust. As one slopes downwards into the memorial entrance, the grey pillars begin to grow taller until they completely consume the visitor. Eventually the grey pillars become smaller again as visitors ascend towards the exit. Some have interpreted this as the rise and fall of the Third Reich or the Regime's gradual momentum of power that allowed them to perpetrate such atrocities on the Jewish community. The space in between the concrete pillars offers a brief encounter with the sunlight. As visitors wander

title: "Memorial to the Murdered Jews of Europe" content: from society and eventually they were removed from existence. The more a visitor descends into the memorial, he or she is without any visible contact of the outside world. He or she is completely ostracized and hidden from the world. It is common for groups of visitors to lose each other as they wander deeper into the memorial. This often reminds one of the separation and loss of family among the Jewish community during the Holocaust. Some have interpreted the shape and color of the grey slabs to represent the loss of identity during the Nazi regime. As one moves

title: "Memorial to the Murdered Jews of Europe" content: lack of unified shape within the group of blocks has also been understood as a symbolic representation of the "task of remembering". Some of the blocks appear to be unfinished. Many see this unfinished appearance as asserting that the task of remembering the Holocaust is never over. Benjamin has said "The monument works to maintain the incomplete". As the effects of the Holocaust are impossible to fully represent, the memorial's structures have remained unfinished. The missing parts of the structure illustrate the missing members of the Jewish community that will never return. The destruction of the Holocaust has resulted in

title: "Memorial to the Murdered Jews of Europe" content: a missing epoch of Jewish heritage. The memorial's structures also deny any sense of collectivity. Some have interpreted this to reflect the lack of collective guilt amongst the German population. Others have interpreted the spatial positioning of the blocks to represent an individual guilt for the Holocaust. Many Germans have viewed the memorial as targeting German society and claim the memorial is presented as "an expression of our – non-Jewish Germans' – responsibility for the past". The site is also enclosed by borders of trees and Berlin's center city. The enclosure from these borders has often evoked feelings of entrapment.

title: "Memorial to the Murdered Jews of Europe" content: This can be understood as a symbolic representation of the closure of European and American borders following the Evian Conference that forced Jews to stay in Germany. Three years after the official opening of the memorial, half of the blocks made from compacting concrete started to crack. While some interpret this defect as an intentional symbolization of the immortality and durability of the Jewish community, the Memorials' Foundation deny this. Many analyze the lack of individual names on the monument as an illustration of the unimaginable number of murdered Jews in the Holocaust. In this way, the memorial illustrates that

title: "Memorial to the Murdered Jews of Europe" content: the number of Jewish individuals lost in the Holocaust was so colossal that is impossible to physically visualize. Several have noted that the number of stelae is identical to the number of pages in the Babylonian Talmud. The information center, which is located at the site's eastern edge, begins with a timeline that lays out the history of the Final Solution, from when the National Socialists took power in 1933 through the murder of 500,000 Soviet Jews in 1941. The rest of the exhibition is divided into four rooms dedicated to personal aspects of the tragedy, e.g. the individual families

title: "Memorial to the Murdered Jews of Europe" content: or the letters thrown from the trains that transported them to the death camps. The "Room of Families" focuses on the fates of 15 specific Jewish families. In the "Room of Names", names of all known Jewish Holocaust victims obtained from the Yad Vashem memorial in Israel are read out loud. Each chamber contains visual reminders of the stelae above: rectangular benches, horizontal floor markers and vertical illuminations. Critics have questioned the placement of the center. It is discreetly placed on the eastern edge of the monument. Architecturally, the information center's most prominent feature lies in its coffered concrete ceilings.

title: "Memorial to the Murdered Jews of Europe" content: The undulating surfaces mirror the pattern of the pillars and pathways overhead, causing the visitor to feel like they have entered a collection of graves. "Aesthetically, the Information Center runs against every intention of the open memorial. The aboveground pavilion of the subterranean documentation area mars the steady measure of the order of rectangles. Admittedly, all objections against this pedagogical extra fall silent when one has descended the stairs to the Information Center and entered the first four rooms". The visitors center contains and displays some of the most important moments and memories of the Holocaust, through carefully chosen examples

title: "Memorial to the Murdered Jews of Europe" content: in a concise and provocative display. The entrances cut through the network of paths defined by the stelae, and the exhibit area gives the memorial that which by its very conception it should not have: a defined attraction. "The exhibitions are literal, a sharp contrast to the amorphous stelae that the memorial is composed of. "It is as if they (exhibits) were directed at people who cannot find the capacity to believe that the Holocaust occurred". The debates over whether to have such a memorial and what form it should take extend back to the late 1980s, when a small

With growing support, the Bundestag passed a resolution in favour of the project. On 25 June 1999, the German Federal Parliament decided to build the memorial designed by Peter Eisenman.

The other winner was a design by Christine Jackob-Marks. Her concept consisted of 100x100 meters large concrete plate, seven meters thick.

The foundation operating the memorial considered this a success; its head, Uwe Neumärker, called the memorial a "tourist magnet". The monument has been criticized for only commemorating the Jewish victims of the Holocaust, however, other memorials have subsequently opened which commemorate other identifiable groups that were also victims of the Nazis, for example, the Memorial to Homosexuals Persecuted Under Nazism (in 2008) and the Memorial to the Sinti and Roma Victims of National Socialism (in 2012).

The first six aircraft produced were designated Series 1, indicating that they were prototype aircraft. The initial production run consisted of Series 100 aircraft, serial numbers seven to 115 inclusive. In 1968, Series 200 production began with serial number 116. Changes made at the beginning of Series 200 production included improving the STOL performance, adding a longer nose that was equipped with a larger baggage compartment (except for aircraft fitted with floats), and fitting a larger door to the rear baggage compartment. All Series 1, 100, and 200 aircraft

Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada, and the park supports a diversity of plants and animals. The park has an elevation range from and contains five major vegetation zones: chaparral and oak woodland, lower montane forest, upper montane forest, subalpine zone, and alpine. Of California's 7,000 plant species, about 50% occur in the Sierra Nevada and more than 20% are within Yosemite. The park contains suitable

The geology of the Yosemite area is characterized by granitic rocks and remnants of older rock. About 10 million years ago, the Sierra Nevada was uplifted and then tilted to form its relatively gentle western slopes and the more dramatic eastern slopes. The uplift increased the steepness of stream and river beds, resulting in the formation of deep, narrow canyons. About one million years ago, snow and ice accumulated, forming glaciers at the higher alpine meadows

On September 7, 2016, the National Park Service accepted the donation of the land, making the meadow the largest addition to Yosemite since 1949. Yosemite National Park is located in the central Sierra Nevada of California. Three wilderness areas are adjacent to Yosemite: the Ansel Adams Wilderness to the southeast, the Hoover Wilderness to the northeast, and the Emigrant Wilderness to the north. The park is roughly the size of the U.S. state of Rhode Island and contains thousands of lakes

Two federally designated Wild and Scenic Rivers, the Merced and the Tuolumne, begin within Yosemite's borders and flow westward through the Sierra foothills, into the Central Valley of California. On average, about 4 million people visit the park each year, with most visitor use concentrated in the seven-square-mile (18 km) area of Yosemite Valley. Almost all of the landforms in the Yosemite area are cut from the granitic rock of the Sierra Nevada Batholith (a batholith is a large mass of intrusive igneous rock that formed deep below the surface).

The high country of Yosemite contains beautiful areas such as Tuolumne Meadows, Dana Meadows, the Clark Range, the Cathedral Range, and the Kuna Crest. The Sierra crest and the Pacific Crest Trail run through Yosemite, with peaks of red metamorphic rock, such as Mount Dana and Mount Gibbs, and granite peaks, such as Mount Conness. Mount Lyell is the highest point in the park, standing at . The Lyell Glacier is the largest glacier in Yosemite National Park and is one of the few remaining in the Sierra Nevada today. The park has three groves of ancient giant

This species grows larger in volume than any other and is one of the tallest and longest-lived. The Tuolumne and Merced River systems originate along the crest of the Sierra Nevada in the park and have carved river canyons deep. The Tuolumne River drains the entire northern portion of the park, an area of approximately . The Merced River begins in the park's southern peaks, primarily the Cathedral and Clark Ranges, and drains an area of approximately . Hydrologic processes,

Heat generated from the Farallon Plate subducting below the North American Plate led to the creation of an island arc of volcanoes on the west coast of proto-North America between the late Devonian and Permian periods. Later volcanism in the Jurassic intruded and covered these rocks in what may have been magmatic activity associated with the early stages of the creation of the Sierra Nevada Batholith. 95% of these rocks were eventually removed by uplifted-accelerated erosion. The first phase of

title: "Yosemite National Park" content: regional plutonism started 210 million years ago in the late Triassic and continued throughout the Jurassic to about 150 million years before present (BP). Around the same time, the Nevadan orogeny built the Nevadan mountain range (also called the Ancestral Sierra Nevada) to a height of . This was directly part of the creation of the Sierra Nevada Batholith, and the resulting rocks were mostly granitic in composition and emplaced about below the surface. The second major pluton emplacement phase lasted from about 120 million to 80 million years ago during the Cretaceous. This was part of the Sevier orogeny.

These igneous deposits blanketed the region north of the Yosemite region. Volcanic activity persisted past 5 million years BP east of the current park borders in the Mono Lake and Long Valley areas. Starting 10 million years ago, vertical movement along the Sierra fault started to uplift the Sierra Nevada. Subsequent tilting of the Sierra block and the resulting accelerated uplift of the Sierra Nevada increased the gradient

Numerous vertical joint planes controlled where and how fast erosion took place. Most of these long, linear and very deep cracks trend northeast or northwest and form parallel, often regularly spaced sets. They were created by uplift-associated pressure release and by the unloading of overlying rock via erosion.

Only the highest peaks, such as Mount Dana and Mount Conness, were not covered by glaciers. Retreating glaciers often left recessional moraines that impounded lakes such as the long Lake Yosemite (a shallow lake that periodically covered much of the floor of Yosemite Valley).

This species, however, is now found in the Yosemite area only around Tioga Pass, where a small, reintroduced population exists. At a variety of elevations, meadows provide important, productive habitat for wildlife. Animals come to feed on the green grasses and use the flowing and standing water found in many meadows. Predators, in turn, are attracted to these areas. The interface between meadow and forest is also favored by many animal species because of the proximity of open areas for foraging and cover for protection. Species that

title: Tetrahedron content: In the case of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid". Like all convex polyhedra, a tetrahedron can be folded from a single sheet of paper. It has two such nets. For any tetrahedron there exists a sphere (called the circumsphere) on which all four vertices lie, and another sphere (the insphere) tangent to the tetrahedron's faces. A regular tetrahedron is one in which all four faces are equilateral triangles. It is one of the five regular Platonic solids, which

title: Tetrahedron content: from "C" to the midpoint of an edge of the base. This follows from the fact that the medians of a triangle intersect at its centroid, and this point divides each of them in two segments, one of which is twice as long as the other (see ). For a regular tetrahedron with side length "a", radius "R" of its circumscribing sphere, and distances "d" from an arbitrary point in 3-space to its four vertices, we have The vertices of a cube can be grouped into two groups of four, each forming a regular tetrahedron (see above, and also ,

title: Tetrahedron content: on this plane, both halves become wedges. This property also applies for tetragonal disphenoids when applied to the two special edge pairs. The tetrahedron can also be represented as a spherical tiling, and projected onto the plane via a stereographic projection. This projection is conformal, preserving angles but not areas or lengths. Straight lines on the sphere are projected as circular arcs on the plane. An isosceles tetrahedron, also called a disphenoid, is a tetrahedron where all four faces are congruent triangles. A space-filling tetrahedron packs with congruent copies of itself to tile space, like the disphenoid tetrahedral honeycomb. In

title: Tetrahedron content: the 1st century Heron's formula for the area of a triangle. Denote "a,b,c" be three edges that meet at a point, and "x,y,z" the opposite edges. Let "V" be the volume of the tetrahedron; then where The above formula uses different expressions with the following formula,The above formula uses six lengths of edges, and the following formula uses three lengths of edges and three angles. If "U", "V", "W", "u", "v", "w" are lengths of edges of the tetrahedron (first three form a triangle; "u" opposite to "U" and so on), then where A plane that divides two opposite edges

Let "d" be the distance between the skew lines formed by opposite edges a and as calculated here. Then another volume formula is given by The tetrahedron has many properties analogous to those of a triangle, including an insphere, circumsphere, medial tetrahedron, and exspheres. It has respective centers such as incenter, circumcenter, excenters, Spieker center and points such as a centroid. However, there is generally no orthocenter in the sense of intersecting altitudes. Gaspard Monge found a center that

title: Tetrahedron content: between its Monge point and circumcenter. These points define the "Euler line" of the tetrahedron that is analogous to the Euler line of a triangle. The nine-point circle of the general triangle has an analogue in the circumsphere of a tetrahedron's medial tetrahedron. It is the twelve-point sphere and besides the centroids of the four faces of the reference tetrahedron, it passes through four substitute "Euler points", one third of the way from the Monge point toward each of the four vertices. Finally it passes through the four base points of orthogonal lines dropped from each Euler point to the

title: Tetrahedron content: Putting any of the four vertices in the role of "O" yields four such identities, but at most three of them are independent: If the "clockwise" sides of three of them are multiplied and the product is inferred to be equal to the product of the "counterclockwise" sides of the same three identities, and then common factors are cancelled from both sides, the result is the fourth identity. Three angles are the angles of some triangle if and only if their sum is 180° (π radians). What condition on 12 angles is necessary and sufficient for them to be the

title: Tetrahedron content: 12 angles of some tetrahedron? Clearly the sum of the angles of any side of the tetrahedron must be 180°. Since there are four such triangles, there are four such constraints on sums of angles, and the number of degrees of freedom is thereby reduced from 12 to 8. The four relations given by this sine law further reduce the number of degrees of freedom, from 8 down to not 4 but 5, since the fourth constraint is not independent of the first three. Thus the space of all shapes of tetrahedra is 5-dimensional. Let be the points of a

Question: who/what operates this aircraft?

Instruction: Utilizing the given image, obtain documents that respond to the following question:

title: "Boeing 767" content: the 777, a larger wide-body twinjet. In the 1990s, the 767 became the most frequently used airliner for transatlantic flights between North America and Europe. The 767 is the first twinjet wide-body type to reach 1,000 aircraft delivered. , Boeing has received 1,224 orders for the 767 from 74 customers with 1,118 delivered. A total of 742 of these aircraft were in service in July 2018. The most popular variant is the 767-300ER with 583 delivered. Delta Air Lines is the largest operator with 77 aircraft. Competitors have included the Airbus A300, A310, and A330-200. Non-passenger variants of the 767

title: "Boeing 767" content: similar to the one which had debuted on 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 lighter construction materials were to be applied to the 7X7. Many of these features were also included in

title: "Boeing 767" content: 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 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 around 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

title: "Boeing 767" content: 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 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 the choice of Pratt & Whitney

title: "Boeing 767" content: in July 1979. The prototype aircraft, registered N767BA and equipped with JT9D turbofans, 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 the inability to retract the landing gear because of a hydraulic fluid leak. The prototype was used for subsequent flight tests.

title: "Boeing 767" content: 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 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

title: "Boeing 767" content: 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 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 the 767-200 in late 1982, while Air

title: "Boeing 767" content: extended-range twin-engine operational performance standards (ETOPS) regulations, the FAA's safety rules governing transoceanic flights by aircraft with two engines. Before the 767, overwater flight paths of twinjets could be no more than 90 minutes away from diversion airports. In May 1985, the FAA granted its first approval for 120-minute ETOPS flights to 767 operators, 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 larger safety margins were permitted because of the improved reliability demonstrated by the

title: "Boeing 767" content: 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 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. By 1988, the 767-X had evolved into an all-new twinjet, which revived the 777 designation. Until the 777's 1995 debut, the 767-300 and 767-300ER remained Boeing's second-largest wide-bodies behind the 747. Buoyed by a recovering global economy and ETOPS approval, 767 sales accelerated in the mid-to-late 1980s; 1989

title: "Boeing 767" content: flights to secondary population centers, thereby eliminating the need for connecting flights. The increased number of cities receiving non-stop services caused 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 the extra weight of the RB211 engines, which are heavier than other 767 engines. During

The first two , featuring extensive modifications to accommodate surveillance radar and other monitoring equipment, were delivered in 1998 to the Japan Self-Defense Forces. 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 the 767-300, and featured an upgraded flight deck, enhanced interior, and greater wingspan. The variant was specifically aimed at Delta Air Lines'

title: "Boeing 767" content: 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 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

title: "Boeing 767" content: 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 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

title: "Boeing 767" content: 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 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, 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

title: "Boeing 767" content: 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 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

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 the flight engineer. The CRTs replace conventional electromechanical instruments found on earlier aircraft. An enhanced flight

title: "Boeing 767" content: 2012, Boeing and Rockwell Collins launched 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 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

title: "Boeing 767" content: 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 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, the Signature Interior features even larger overhead bins, indirect lighting,

title: "Boeing 767" content: 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. The International Civil Aviation Organization (ICAO) aircraft type designator system uses 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
