The McDonnell-Douglas MD-11
I
The successor to McDonnell-Douglas MD-11, for the previous DC-10 widebody and the third tri-jet DC-after the same 10 and Lockheed L-1011 TriStar, traces its origins to the General Electric and Pratt and Whitney engine competition to provide a suitable engine for Lockheed transport C-5A Galaxy military, resulting in the first turbofan high-pass ratio, while the DC-10, 1966 the result of requirements for an American Airlines aircraft 250-pasenger transcontinental passengers, was built in five basic versions, including the DC-10-10, the DC-10-15, the DC-10-30, the DC-10-40, and the KC-10 Extender achieving a final production run of 446. program cost overruns had intermittently demanded the merger of McDonnell Douglas Aircraft Company with so far a manufacturer of military aircraft in order to ensure the survival of the company and its planes.
design studies for both Douglas successors narrow-body wide, driven by high bypass ratio turbofans and capacity for 150 passengers, had already begun in the late 1970s. Although there was no Final aircraft program, the event started, detailed market analysis and new technology research, be useful later for the final design. The 60 orders for the KC-10 has maintained the Douglas DC-10 base production line longer than it would if it is based only on orders business, delaying the need for a replacement. However, because it would rely on its counterpart in previous generations, could come through its definition and design phase much faster than the afternoon, competing Airbus A-340 and Boeing 777, to enter the market sooner than the aircraft and building a base existing DC-10 customers for potential sales.
Unlike aircraft, however – whose five basic versions had shared the same fuselage length and cross-section – the planned successor to 1979 had offered a 40-foot fuselage with a capacity for 340 passengers in mixed class, three General Electric turbofans CF6-50J production of 54,000 pounds of thrust each, an enhanced wing, and a gross weight of 630,000 pounds.
The resulting DC-10-60, parallel to it, stretched, long-range DC-8-60 series, had offered an increase of 75-passenger on the DC-10 Air New Zealand and Swissair, which had been targeted as potential launch customers, but the use of existing wing had seriously eroded the performance, and extensions of five feet, along with a new fillet flaps its wings and assets to reduce gust loads, had improved considerably. In fact, revised and final edge flaps of a larger tailcone had resulted in a fuel reduction of 24 percent over the DC-10 and its seat-mile costs had been lower than those of the four Boeing 747 engines.
launch the program, intended for 1979, there were been usurped by a more precise definition of its versions Douglas, who under the name "DC-10-61", "DC-10-62," and "DC-10-63," was more closely reflects the DC-8-61 DC-8-62, and nomenclatures DC-8-63. The DC-10-61, for example, had been conceived as a domestic alternative to stretching the fuselage 40 feet and a capacity of 390 passengers, and had been driven by engines of 60,000 pounds of thrust. The DC-10-62 with a reduced insertion, fuselage 26.7 meters in height, had been intended for long-range operations, an increase of 14 foot wingspan, flaps assets, and a central line of four wheel drive main landing gear. He had planned to carry some 40 passengers unless the -61, -63, while the combination had the design features of both, resulting in high capacity long-range variant.
A series of intermittent DC-10 accidents, none of whom had been associated with an inherent design flaw, along with the recession economic situation, had prevented further Super DC-10 in development this time, although one of its characteristics over time has added to its successor, had been tested Continental Airlines flight in a DC-10-10 in August 1981. winglets, which extends both above and below the wing tip, and vary in size, had resulted fuel in a reduction of three percent due to an equal decrease in the friction generated.
Thus, driven only by the MD-80 sales, Douglas Aircraft Company recession mounted., Is projected to replace DC-10, bearing a designation MD-11X-10 in 1984 which offers much more advance than the original Super Series 60 had, was more closely based on the DC-10-30 with a maximum of 580,000 pounds to take a wide-6500 nautical miles with a full load, and three whether General Electric CF6-80C2 or Pratt and Whitney PW4000 engines. A higher capacity version, which will be offered in parallel with the basic airframe, fuselage had submitted a height 22.3 meters long, 331 to permit mixed-class passengers to be carried over ranges of 6,000 miles with a corresponding gross weight of 590,000 pounds. American, Delta, Lufthansa Airlines and Toa interior, taking into account this iteration, suggested improvements that were later incorporated in the final plane.
The following year, the Board authorized warrant applications, but both versions had, for once, had the same fuselage length, medium-range variant, a gross weight of 500,000 pounds, with a 4.781 miles wide, and long-range counterpart, with a gross weight of 590.000 pounds, with a large 6.900 miles. For about 335 passengers in a typical mixed systems were introduced in the composite material, a cabin for two, and an advanced electronic flight system.
In the time of release of the official program, which had occurred on December 30, 1986, 92 orders and choice had been left by Alitalia, British Caledonian, Federal Express, Korean Air, SAS, Swissair, Thai Airways International and Varig.
The MD-11, which was first deployed three years later, in September 1989 in Long Beach, California, and had been N111MD registered, had been stripped of its engine, wings, vertical stabilizer, and the paint scheme, but it shows the logos of the 29 customers who had ordered or type of option at this time. As these areas have been added later, however, kept a similarity to the DC-10-30's that had resulted.
With a length of 18.6 feet above the aircraft, achieved by means of two fuselage plugs, kept his nose and sections cabin, but introduced a long, drag reduction, tailcone chisel-shaped, and offered a total length of 201.4 feet when equipped with General Electric engines, or an overall length of 200.11 meters with Pratt & Whitney power plants.
The two Douglas aerofoil mast, built of chordwise ribs and skins spanwise reinforcements, there is a period of 169.6 meters, a sweepback 35 degrees in the chord quarter and six degrees of dihedral, an aspect ratio of 7.9 representing and an area of 3.648 square feet. low-speed lift was augmented by new, full-span leading edge slats and redesigned, behind the double slit fins edge, while controlling body roll was provided on the inside of the hull, at any speed metal flaps and composite skin outboard motor, low speed aileron who bowed to the trailing edge flaps for takeoff and were entirely of a composite material. Each wing also contained five panels spoiler.
Fuel made in the wing integral tanks amounted to 40,183 U.S. gallons.
Up-and downward winglets installed in the very tips of the wings, had provided the highest honor that the DC-10. Use of the vortex drag produce anything created by wingtips mixture pressure differential that had been formed by a two meter section angled up, made of a conventional rib and spar, but covered with an aluminum alloy and leather complete with a carbon fiber trailing edge, and 2.5 meters high, the lower section to the right angle made entirely of carbon fiber, collectively covering an area of 40 square meters.
So far more than arm and controlled by computer software to increase longitudinal stability, the MD-11 horizontal tail had been 30 percent smaller than the DC-10 and get a tank of 2,000 U.S. gallons member of the wider setting and facilitated the flight center of gravity of the optimization. Its advanced aerodynamic surface, curved, and reduced 33-degree sweepback, along with a variable incidence stabilizer equipped with two electro-active sections slotted final compound lifts on each side edge, gave rise to a 1900 pounds of weight reduction and decrease drag in flight.
Power had been provided by three 62,000 lbs thrust General Electric CF6-80C2 or 60,000 lb thrust Pratt and Whitney PW4462 high-bypass ratio turbofans, two of which had been registered at the lower basin of the wing leading edge and one of whom had settled in the queue behind the drawer vertical torsion fin. Tracing its origins to the 41,000 pounds of thrust TF39 engine originally developed for the Lockheed C-5A Galaxy, the former had become the most silent advanced CF-6 for commercial operation and its 40,000 pounds of thrust CF6-6D had fed the internal DC-10-10, while 48,000 pounds of thrust CF6-50C had the DC-powered intercontinental 10-30, with the Airbus A-300 and some versions of the Boeing 747. The most advanced CF6-80A was also chosen to provide the A-310 767.
The incorporation of the CF-6 is deep, with a larger 93-inch fan, two axes, the CF6-80C2 feeding of MD-11 had offered 17-percent more thrust and had a bypass ratio of 5.05. Linked to a full authority digital engine control, which had provided accelerator and an interface electronic automatic flight management system, the turbine had offered to reduce fuel consumption.
The alternative Whitney PW4060 and Pratt, whose short length decreased as the total length of the aircraft by two inches, had been the only option other customer. The Rolls Royce Trent RB.211-524L, summarized as a third alternative, had been specified by Air Europa for their firm and 18 option orders, but the financial collapse its parent company had prevented their continued supply.
The hydraulically operated, tricycle landing gear, such as the DC-10-30, had been made by a twin-wheel nose unit forward-retractable, two of four wheels, side retractable main gear bogies and a double with two wheels, with vision retraction strut center fuselage, all of which had offered oleo-pneumatic shock absorbers.
The MD-11 cockpit, deviates significantly DC-10 had been operated by a crew of two, the third, or the flight engineer position replaced by digital avionics and flight control computer and management systems, while the control system aircraft, or ASU, was composed of five separate computers, dual-channel automated all its functions above.
The passenger cabin is designed for flexibility, had built the seat, the kitchen sink, clothes closet and installation cabin on the tracks whose length is running a one-inch increments provided multiple configurations and densities and rapid rearrangements, thus allowing companies to operate the type on scheduled during the week and services high-density/charter weekends. Compared with the DC-10 cabin, the MD-11 appears lighter side panels and seat sets, better lighting, larger compartments, renovated storage operating costs tripled passenger volume by three cubic feet, standard containers longitudinal centerline of the second door, and the provision for overhead bed rest crews.
A typical two-class, 323-passenger configuration, 34 days had forced six first class seats in a 41 – to launch 42-inch and 289 nine-day tourist-class seats in a 33 – to 34-inch throw, while a three classes had included 16 six abreast seats first class in a field of 60-inch, 56 seven-day business class seats in a field of 38-inch and 221 nine-abreast seating in economy class by 32-inch field. Maximum capacity by ten per day, three four-three configuration, was 409.
The MD-11 with a payload of 114 100 pounds limited weight, had a 602,500 lbs maximum take off weight. With capacity for 298 passengers in three classes, which had offered a 6840-nautical mile range, including reservations required by the FAA.
Firstly, taking its first flight on January 10, 1990 in Long Beach, the MD-11 had tested the stability and control of the base Edwards Air Force, reaching a maximum altitude of 25,000 feet and 300 knots before concluding a successful two-hour, 56 minutes, first flight. Three hundred fifteen and options orders were received for the type at the moment.
The certification program, which had led to four General Electric CF6-80C2 and Pratt & Whitney PW4460-body power, there were several notches above the tri-jet business records, including a 9080 miles flight from Anchorage, Alaska, 31 July 1990 with the fourth prototype, which remained aloft for 16 hours, 35 minutes.
Type certification was achieved on 8 November for the CF6-80C2 power version and 19 December for the PW4460 aircraft, while it had authorized for Category IIIB landing following April.

Finnair, the client type of launch, had received its first aircraft, registration OH-LGA, at a ceremony in Long Beach on November 29, 1990, and a representative sector This intercontinental aircraft had made two years later, in October 1992.
Founded on November 1, 1923 by Bruno L. Lucander, the company Private, called "Aero O / Y" service was inaugurated the following March to Reval, Estonia with Junkers F.13 aircraft, before expanding to Stockholm with an intermediate stop in Turku, in cooperation with ABA of Sweden. Finnish development of national highways, due to the abundance of lakes country, the team did need a seaplane, although construction of the airport post-1936 has afforded two de Havilland Dragon Rapide biplanes and later two Ju.52/3ms Junkers.
Shortly after World War II the suspension of flights, the mandate was lifted, the fledgling airline, the government now 70-percent property and the name "Aero O / Y End Air Lines, had restored their Helsinki-Stockholm sector and acquired nine DC-3.
The 1950s characterized by continental expansion route network and modern, the Convair 340 aircraft acquisitions, had led to Dusseldorf, Hamburg, London and Moscow from Helsinki Flight Center in constant expansion, and the guy had been replaced by the slightly higher capacity 440 Convair.
The Sud-Aviation Caravelle SE.210-1A its first team of pure reaction, had replaced the pistonliners and had reduced flight time in Stockholm and Frankfurt routes, and the larger the, SE.210-10B, first delivered in 1964, eventually became the standard, four years before been officially new "Finnair."
The Douglas DC-8-62CF, his first long-range four-engine jet, was issued on January 27, 1969 and was enabled to launch intercontinental services Helsinki to New York via Copenhagen and Amsterdam on March 15 for the first time. The first of five DC-10-30, its wide-body aircraft in the first place had been accepted in 1975, and two Airbus A-300B4s was acquired 11 years later, in 1986, for the charter service.
The MD-11 powered by General Electric CF6-80C2D1F and configured for 58 business class and 278 economy class passengers, had been ordered to replace its DC-10-30s, and was first deployed on the route Helsinki-Tenerife on December 29, 1990, initial operational experience to accumulate before being transferred to the fields of North America and the Far East for what had been expected.
Operating a fleet of Airbus and McDonnell Douglas-made up of two MD-11s, five DC-10-30, two A-300B4s, 14 MD-82s and-83s, three MD-87s and 17 DC-9-40 50 years by falling 1992, Finnair carried 5.236 million passengers in a national, international and intercontinental network and charter routes, covering 25 destinations in Finland, 31 in Europe, two in North America and four in Asia. The first had been mostly operated on its behalf by Karair, which had a fleet of five ATR 72s and Finnaviation, who had SF flown six 340s. His two MD-11s were operated Helsinki Helsinki-Tokyo-Bangkok-Singapore route, while its DC-10-30 has continued to serve parts of New York and Beijing.
The first, to Japan, was distributed to 4862 miles and forced a nine-hour lock time of 35 minutes, and had been operated by the first MD-11 to enter passenger service, OH-LGA.
Tall trees and dense surrounding Helsinki Vantaa International Airport, fall coats still yellow and gold, appeared diffuse and the bite, the wind turned 30 degrees snowflakes to the geometric design of the ramps taxiways and runways. Goliath, blue-trimmed Finnair MD-11 tri-jet, currently only in the white widebody sprinkled with asphalt accompanied by a multitude of narrow body DC-9, MD-80, and twinjets 737-300, was towed to gate A-4 30 minutes before the scheduled time, starting in 1620 through the late afternoon, decreased Nordic light.
The MD-11 cabin for two, a radical break with the DC-10 years, had six eight square inch Cathode Ray Tube (CRT) glass display units, composed of duplicated primary flight display (PFD), Navigation Display (ND), engine and alert display (EAD), and systems Display (SD) schemes, while the automatic system controllers, located in the upper panel, is divided into sections for hydraulic, electric pneumatic, and fuel, each controlled by two independent teams. The Flight Control Panel (FCP) itself, located in the Control Panel Glareshield (BPC), introduced autopilot controls and mode of selection of flight director and flight management system of exchange controls so inclusive rate (SPD), navigation (NAV), and profile (PROF).
The wait, the departure of Siberia and the destination points, weights, times, flight plan, the off track (04) and make the best of the calculations obtained from the load sheet prepared the station had been entered on the keyboard, resembles Multifunction Control Display Unit (MCDU) located in the central pedestal between the two pilots. The flight of Standard Instrument Departure (SID) had subsequently been loaded into the flight management system during the initialization of the inertial reference system.
The number three engine, the first to operate and further from the bleed air source, had been engaged by pulling the switch to start the engine, the valve starts moving in the open position, which have verified by an amber light for confirmation. When the compressor speed N2 had equaled 15 percent, the choke lever was moved to the position "On" and the engine starter switch, reflecting an exhaust gas temperature (EGT) of between 45 – and 52 percent-had appeared in the valve disilluminating boot closed and the amber light. N1 engine tachometer had been established in 23 percent and its exhaust gas temperature had hovered in the mark 700 degrees Fahrenheit. The sequence was repeated for the other two turbofans, followed by success in the List of Home "After."
Tira and maneuvered his nose in parking position, the MD-11, operating as flight AY 914, had begun his independent movement, with almost imperceptible progress of accelerator, tests on their surfaces after Vantaa flight and Ground Control taxiing instructions.
Surfing the snow-patched, blue-lined streets of shooting in the dark virtual, the heavy tri-jet was a 180 degrees to the runway 04 with the help of her rudder nose wheel, nose wheel was positioned far behind the cockpit, the aircraft had been moved far beyond the centerline of the strip before it had actually started turning toward her, his body long, wide track following mode. full rudder deflection always ten degrees of the direction on the ground while the nose wheel to reach 70 percent of left and right laterability.
Receiving cleaning off the MD-11 sports 25 degrees of final front cover, had been a thunder the initial acceleration as accelerators, manually advanced to the position 70-percent, fueled its enormous diameter of General Electric turbofans with a constant flow fuel, as they eat large amounts of cold air with each other, the increasingly rapid rotation of the fan. AutoPilot button, located on the Panel Flight Control and autothrottle own participation, computer-controlled aircraft in your own setting takeoff thrust, with automatic synchronization engine.
Lift-leveraged in a nose wheel rotation, this release, the tri-jet surrendered at dusk purple, snowflake-blur, its load fuel, putting a load of flex-curved wingtip and wing leading edge light beams slice through the darkness, as it went along the track 15 and the low light spots representing Helsinki. Its landing gear retractable tricycle, the aircraft, whose field had indicated his attitude bar up correctly, automatically is attached to its normal output of the instrument.
The electric arc in a shallow right bank of the coast, flying 914 of its fins retracted edge escape, despite its leading edge slats had been postponed until the extra speed had accumulated. Mode active participation of the aircraft navigation to fly out his profile, while the activation of automatic flight system, together with the net assets "and" PROF "buttons, said he was followed your route, climbing, radial output and air traffic control assigned or whether the level of compensation of altitude. Airspeed was maintained at 250 knots below 10,000 feet, in which time has been speeded up to 355 or more, and its leading edge lights had been discarded.
Overcoming one of the many layers of clouds, aircraft crossed the Gulf of Finland, whose dark purple area of the horizon had been separated by a diffuse band of pale green light. Increasingly confined howling in the wake, it passed over the coast of the former Soviet Union at a speed of 472-knot ground, flying southwest of St. Petersburg in black sky that had been drawn by a thin, bright orange line on the western horizon, is now behind your left wingtip as it settled into its initial plateau, 33,000 feet in a field of 509-knot speed, for the Urals and Siberia.
The cabin sports diagonal with drawings, light and dark blue upholstery, had offered six rows of seven per day, two, three, two, set class seats on the front, followed by another at the stern of the cruise three seconds. seats economic class, entirely in one of ten deep, three-four and three years, arrangement, has included nine rows behind the business class and 21 in the aft cabin, which runs between the third and fourth cross aisles.
Dinner in the second, according to his bilingual English and Japanese menu (which, in October 1992, ironically had offered a profile on a Finnair flight DC-10-30), had included a selection of snacks, beer, wine and soft drinks served with peanuts and almonds lightly smoked salt, a crab meat and mushrooms seafood salad on a bed of lettuce with jumbo shrimp, sliced cucumbers and cherry tomatoes, a basket of warm white and wheat breads Finland butter, beef or chicken mango curry sauce and coconut cream, French camembert cheese, rye crackers, raspberry mousse cake, coffee Japanese tea or a selection of liquors, mints after dinner, and warm towels.
In-flight entertainment was covered, trilingual high quality Finnair Blue Wings magazine, who has devoted nearly 40 pages to the specific carriers, 14 channels of audio programming accessed through padded headphones, stereo, and two feature films.
Maintaining a low speed of 567-knot, the MD-11, penetrated the tropopause less 62-egree in an attitude of three degrees nose high, passing southeast of Arkhangelsk on the frozen tundra of Siberia, with seven hours, 30 minutes left on his flight plan. Thinning layer of clouds, which appear as covering veils, orange and white papers revealed the population of central pearls consistently represented under the party Excel, turbofans mass diameter, and that propelled to Adak and then south of Naryan-Mar
Alien or passengers, upper and lower fins delayed pressure otherwise created vortex mixing wingtips differential, reducing friction, while the adjustment of the horizontal stabilizer tank-situated had allowed the aircraft to shift its center of gravity back toward its limit of 34 percent aft design, reducing friction and fuel matching record 2.7 percent. The guy had standard operating mode within a 29 – to 32-percent range.
Oblivious to the passengers, the upper and lower fins delayed otherwise the pressure created vortex mixing wingtips differential, reducing friction, while the adjustment of the horizontal stabilizer tank, had located allowed the aircraft to shift its center of gravity back toward its limit of 34 percent aft design, reducing friction and fuel a matching record 2.7 percent. The guy had worked as standard in a 29 – to 32-percent range.
Flight 914 of the progress of the flight plan, indicated by a series of position and ground speed readings, had been the result of the position of the IRU and the coordination of the speed with VHF omnidirectional radio range (VOR) and distance measuring equipment (DME) stations between Finland and Japan. The Flight Plan (F-PLN) from selected in the MCDU screen gave the aircraft position and points aligned vertically on the screen, with the estimated time next to them, along with the speed and altitude, shown as "Position", "Estimated time above "(ETO)," Speed "(SPD), and" Flight Level "(ALT).
Irkutsk passing over the Cordillera Yabblonovyy and Tsitisihar, the plane never moved eastward to Vladivostok.
Cutting through the darkness and the day of the opening in the East, razor dawn crossed the eastern horizon with a thin section through which an orange glow had dumped in front of the port wing, somehow, emphasizing the character cylindrical planet on which the tri-jet arc current. "Tomorrow," apparently anxious to give vent to his strength, flow through the crack little by little, the expansion marks the line of demarcation between the two modes of 24-hour cycle, light to enhance and transform the black fate, night Siberia a cold, dark purple and partially habitable last blue before dawn. The amount of humanity and the awakening to light later in the vast land had been, without doubt, infinitesimal. The sun, appearing red mercury, liquid immersed in a sea of gray-black, little by little succeeded during the night, his superior, the edge head as indistinguishable as shyly revealed the rest of his body, illuminating the ice cover, the crust of corrugated roller coasters that covers the area immediately below the fuselage. At first it seemed to float in a sea of dark brown, which became independent distinguishable as the sun spread its rays lighting like the limbs pointing to them.
Overlooking winding, copper, reflecting the rivers, the 914 flight consumed two hours, 11 minutes left its flight plan.
Aromas of coffee brewed led the stunned, especially sleeping passengers on night sleep in the cabin, a single process increased by the previous breakfast hot scented towels. The food was included orange juice, a three-egg omelet filled with creamed spinach, thick sliced Danish ham, assorted rolls, Swiss black cherry preserves, cheese fondue in Finnish, cream wafers and coffee or tea.
Banking on a southeast heading with the help of fins inside the MD-11 had, after virtually the length of your cruise, left Soviet airspace for the first time snow-dust, chocolate color peaks whose peak had been careful to funnels graze vaporous mist, following the coast and the morning sun reflected from the copper surface Sea of Japan. One hour, 23 minutes had been to Tokyo.
Suspended motionless on the surface of glass-like water, which sailed beyond silver peak of Mount Fuji, now maintaining a south almost due course heading of 180 degrees. Banking clusters left over patches, who built his last link Japan, with its time of arrival at destination simply unwind the 40-minute mark.
The crests of the definition of the island of Honshu appeared before.
Tokyo had been reporting clear skies and temperatures of 20 degrees Celsius.
Along the coast of Niigata, the MD-11 had come to a position northeast of its destination, with 25 minutes to the end of its flight plan, disengaging himself from the air plateau for the first time in nearly nine hours half of the cabin-selected "NAV" and "PROF" modes.
Induced in the nose downward descent profile for more trail, the 914 flight path Coast briefly before moving along the whitecapped Pacific ATC now vector in a series of three banks right. Automatically guided the plane to speed reduced to 250 knots and had traveled the speed restriction of 10,000 feet, adhering to standard terminal arrival route (STAR), driven by its three N1 tachometers mass turbofans which were recorded quasi-steady, readings of 34 percent.
An air traffic control-applied for the reduction speed, 200 knots, had, according to the tape speed, requires a head start on the final extent of the flap, 15 degrees.
When the plane had plunged more than brown, beige, green farmland with geometric designs on its final approach heading of 340 degrees, the captain had selected the approach or the tiles of the earth, the automatic landing system armed by an instrument landing system (ILS) approach and ready to capture glide slope and localizer. Focus page of the MCDU, giving the weight of landing, the runway, barometric pressure readings and final configuration flap speed identified the following RJAA, ICAO four-letter code of Tokyo-Narita: a 208-knot "clean" of speed, a flap 158-knot speed at 28-degree extension position, an approach speed of 161 knots with 35 degrees of flap, a 158-V-knot speed reference and a touchdown speed of 150 knots.
Sporting significantly larger wing area with leading edge slat and the end extensions 35 degrees flap edge, blue-trimmed Finnair MD-11, projecting their train tricycle landing gear with four claws extended, made its final approach on the outskirts of Narita in the morning without problems blue, passing the runway threshold. Sinking into the concrete, during the time it is requested altitude had been generated by computer, the widebody tri-jet was launched by seven degrees, the flare nose high, slowing to idle authothrottle 50 feet and allowing the ground to cushion the effect of the main gear contact. manually strangled in inverter mode thrust, which had unleashed its upper surface of the wing spoilers, the handle being moved from the retraction (RET) the establishment through the "1 / 3 "" 2 / 3 "and" Full marks "as the plane slowed. The nose wheel sank to the ground.
Taxiing to satellite Four of Narita International Airport's South Wing, the aircraft was moved to its parking place at Gate 44 0855 local time, ending its intercontinental flight sector and completing the circular pattern of nose-wide-body aircraft, consisting of an Austrian Airlines A-310-300, a Japan Air Lines 747-200B, a British 747-400 Airways, ANA 747-200B, a Northwest 747-200B, and a Swissair MD-11.

MD-11 initial service was not always so routine. In fact, the plane had shown gross weight and the resistance increases well above the projected results, leading to the payload and range of impairments, and Robert Crandall, then CEO of American Airlines, had refused to accept delivery of the type, the replacement of an existing DC-10-30 in the San Jose-Tokyo route for which it had been expected. A series of performance improvement packages (PIPs), focusing on the shortcomings, ultimately, the situation had been corrected.
At January 1 1996, 147 MD-11 had been delivered to 24 original clients and agents who had participated collectively the aircraft daily utilization of 11.6 hours, experiencing a 98.3 percent dispatch reliability.
Apart from the initial MD-11 passengers, several other versions, although in very limited quantities had been produced.
The MD-11 Combi, for example, had offered a stern door on the left, opening up transport of goods, allowing several percentages passengers, 168 to 240, and cargo, ranging from four to ten pallets, which shall appear on the main deck, while the lower deck space had not changed. With a payload of 144,900 pounds of limited weight, the aircraft had a maximum range of between 5180 and 6860 miles nautical.
The MD-11CF Convertible Freighter had offered the main deck door was moved to the front port side. Martinair Holland, launch customer for the variant in August 1991, had placed four firm orders and an option for the type.
The MD-11F, with a payload of 202.100 pounds, was a pure cargo, passengers without windows or facilities FedEx ordered by internal, while the MD-11er Extended Range, released in February 1994, had offered an increase of 3,000 U.S. gallons fuel capacity carried in tanks penthouse aides, a payload of 6000 pounds higher, a range of 480 miles, and have a fresh weight of 630,500 pounds. World Airways, selection of Pratt and Whitney PW4462 engine, and Garuda Indonesia, specifying its counterpart General Electric CF6-80C2, had placed orders to launch.
The decline in sales, the result of the shortcomings of the initial design results, critiques of American Airlines, damaging the public reputation, cancellations orders, and competition for the Airbus A-340 and Boeing 777, had forced the McDonnell-Douglas to record $ 1,800,000 for the program in 1996 and the following year, after the merger of McDonnell-Douglas with Boeing Commercial Airplane Company, which was no longer viable to continue production. The original Douglas Aircraft Company Building 84, located in Long Beach airport and the point of incubation for all McDonnell-Douglas DC-10 and MD-11 widebody aircraft, three, was born last 200 MD-11 cargo ship, for Lufthansa Cargo, in June 2000 and the aircraft towed across the road to the track, titled "The perfect end to a was perfect. "
