McDonnell Douglas MD-11

The McDonnell Douglas MD-11 is a three-engine medium- to long-range wide-body jet airliner, manufactured by McDonnell Douglas and, later, by Boeing Commercial Airplanes. Based on the DC-10, it features a stretched fuselage, increased wingspan with winglets, refined airfoils on the wing and smaller tailplane, new engines and increased use of composite materials. Two of its engines are mounted on underwing pylons and a third engine at the base of the vertical stabilizer. It also features an all-digital glass cockpit that decreases the flight deck crew from the three required on the DC-10 to two by eliminating the need for a flight engineer.

Development

Although the MD-11 program was launched in 1986, McDonnell Douglas started to search for a DC-10 derivative as early as 1976. Two versions were considered then, a DC-10-10 with a fuselage stretch of 40 feet (12 m) and a DC-10-30 stretched by 30 feet (9.1 m). That later version would have been capable of transporting up to 340 passengers in a multi-class configuration, or 277 passengers and their luggage over 5,300 nautical miles (9,800 km). At the same time, the manufacturer was searching to reduce wing and engine drag on the trijet. Another version of the aircraft was also envisaged, the "DC-10 global", aimed to counter the risks of loss of orders for the DC-10-30 that the Boeing 747SP and its range were creating. The DC-10 global would have incorporated more fuel tanks.

While continuing their research for a new aircraft, McDonnell Douglas designated the program DC-10 Super 60, previously known for a short time as DC-10 Super 50. The Super 60 was to be an intercontinental aircraft incorporating many aerodynamic improvements in the wings, and a fuselage lengthened by 26 feet 8 inches (8.13 m) to allow for up to 350 passengers to be seated in a mixed-class layout, compared to 275 in the same configuration of the DC-10.

Following more refinements, in 1979 the DC-10 Super 60 was proposed in three distinct versions like the DC-8. The DC-10-61 was designed to be a high-capacity medium-range aircraft. It would have a fuselage stretch of 40 feet (12 m) over the earlier DC-10 models, enabling it to carry 390 passengers in a mixed class or 550 passengers in an all-economy layout, similar to Boeing's later 777-300 and Airbus A340-600. Like for the DC-8, the series 62 was proposed for long-range routes. It would feature a more modest fuselage stretch of 26 ft 7 in (8.10 m), along with an increased wingspan and fuel capacity. It would be capable of carrying up to 350 passengers (mixed class) or 440 passengers (all-economy), similar to the later Boeing 777-200 or the Airbus A330-300/A340-300/500. Finally, the series 63 would have incorporated the same fuselage as the DC-10-61 as well as all the larger wing of the -62. After three high-profile accidents in the 1970s (Turkish Airlines Flight 981, American Airlines Flight 191, and Air New Zealand Flight 901), the trijet's reputation was seriously damaged by doubts regarding its structural integrity. For these reasons, and due to a downturn in the airline industry, all work on the Super 60 was stopped.

In 1981, a Continental DC-10-10 (registration number N68048) was leased to conduct more research, particularly the effects the newly designed winglets would have on aircraft performance. Different types of winglets were tested during that time in conjunction with NASA. McDonnell Douglas was again planning new DC-10 versions that could incorporate winglets and more efficient engines developed at the time by Pratt & Whitney (PW2037) and Rolls-Royce (RB.211-535F4). The manufacturer finally rationalized all these studies under the MD-EEE (Ecology-Economy-Efficiency) designation, that was later modified to the MD-100 following some more changes. The MD-100 was proposed in two versions: the Series 10, having an airframe shorter by 6 ft 6 in (1.98 m) compared to the DC-10 and seating up to 270 passengers in a mixed-class configuration; and the Series 20, incorporating a fuselage stretch of 20 ft 6 in (6.25 m) over the DC-10 and able to seat up to 333 passengers in the same kind of configuration as the Series 10. Both versions could be powered by the same engine families as the actual MD-11 plus the RB.211-600. However, the situation for the manufacturer, and the airline industry in general, did not look bright. No new DC-10 orders were received, and many among the observers and customers doubted that the manufacturer would be operating much longer. Thus, the Board of Directors decided in November 1983 to once again cease all work on the projected new trijet.

The following year no new orders for the DC-10 were received. The production line was kept active thanks to earlier orders from the U.S. Air Force for 60 KC-10A tankers. McDonnell Douglas was still convinced that a new derivative for the DC-10 was needed, as shown by the second-hand market for their Series 30 and the heavier DC-10-30ER version. Thus, in 1984 a new derivative aircraft version of the DC-10 was designated MD-11. From the very beginning, the MD-11X was conceived in two different versions. The MD-11X-10, based on a DC-10-30 airframe, offered a range of 6,500 nautical miles (12,000 km) with passengers. That first version would have had a maximum takeoff weight (MTOW) of 580,000 pounds (260,000 kg) and would have used CF6-C2 or PW4000 engines. The MD-11X-20 was to have a longer fuselage, accommodating up to 331 passengers in a mixed-class layout, and a range of 6,000 nautical miles (11,000 km).

As more orders for the DC-10 were received, McDonnell Douglas used the time gained before the end of DC-10 production to consult with potential customers and to refine the proposed new trijet. In July 1985, the Board of Directors authorized the Long Beach plant to offer the MD-11 to potential customers. At the time, the aircraft was still proposed in two versions, both with the same fuselage length, a stretch of 22 ft 3 in (6.78 m) over the DC-10 airframe, as well as the same engine choice as the MD-11X. One version would have a range of 4,780 nautical miles (8,850 km) with a gross weight of 500,000 pounds (230,000 kg) and transport up to 337 passengers, while the second would carry 331 passengers over 6,900 nautical miles (12,800 km). A year later, as several airlines had committed to the MD-11, the situation was looking optimistic. The aircraft was now a 320-seater baseline and defined as an 18 ft 7 in (5.66 m) stretch over the DC-10-30 powered by the new advanced turbofans offered by the major engine manufacturers and giving it a range of 6,800 nautical miles (12,600 km). Other versions, such as a shortened ER with a range of 7,500 nautical miles (13,900 km), an all-cargo offering a maximum payload of 200,970 pounds (91,160 kg) and a Combi with a provision for ten freight pallets on the main deck, were proposed. Further growth of the aircraft was also foreseen, such as the MD-11 Advanced.

Design phase

Finally, the MD-11 was launched on December 30, 1986 with commitments for 52 firm orders and 40 options in three different versions (passenger, combi and freighter) from ten airlines (Alitalia, British Caledonian, Dragonair, FedEx Express, Finnair, Korean Air , Scandinavian Airlines System, Swissair, Thai Airways International , and Varig) and two leasing companies (Guinness Peat Aviation and Mitsui). Orders from Dragonair, Scandinavian and UTA, an undisclosed customer, were canceled by 1988.

Assembly of the first MD-11 began on March 9, 1988, and the mating of the fuselage with wings occurred in October that year. The first flight was originally planned to occur in March 1989, but numerous problems with the manufacturing, delays with suppliers producing essential components and labor industrial actions delayed the ceremonial roll out of the prototype until September of that year. The following months were used to prepare the prototype for its maiden flight, which finally happened on January 10, 1990. The first two aircraft manufactured were intended for FedEx and thus, were already fitted with the forward side cargo door. They remained with the manufacturer as test aircraft until 1991 before being completely converted to freighters and delivered to their customer. FAA certification was achieved on November 8, 1990 while the European Joint Aviation Authorities (JAA) certified the MD-11 on October 17, 1991 after approximately 200 separate issues were resolved.

Yugoslav Airlines, already flying several DC-10s, became the first customer of the MD-11. Three aircraft were manufactured but were never delivered due to war in Yugoslavia. The first MD-11 was delivered to Finnair on December 7, 1990 and it accomplished the first revenue service by an MD-11 on December 20, 1990, carrying passengers from Helsinki to Tenerife in the Canary Islands. MD-11 service in the U.S. was inaugurated by Delta Air Lines, also in 1990. It was during this period that flaws in the MD-11's performance became apparent. It failed to meet its targets for range and fuel burn. American Airlines in particular was unimpressed, as was Singapore Airlines, who canceled their order for 20 aircraft. American Airlines cited problems with the performance of the airframe and the Pratt & Whitney PW4000 engines as reasons for the cancellation while the Singapore Airlines stated that the MD-11 could not operate on the airline's long haul routes. Pre-flight estimates indicated that the P&W-powered MD-11 was to have a 7,000 nautical miles (13,000 km) range with 61,000 pounds (28,000 kg) of payload. With the Phase 1 drag reduction in place then, the aircraft could only achieve its full range with 48,500 pounds (22,000 kg) of payload, or a reduced range of 6,493 nautical miles (12,025 km) with a full payload.

In 1990, McDonnell Douglas, along with Pratt & Whitney and General Electric began a modification program known as the Performance Improvement Program (PIP) to improve the aircraft's weight, fuel capacity, engine performance and aerodynamics. McDonnell Douglas worked with NASA's Langley Research Center to study aerodynamic improvements. The PIP lasted until 1995 and recovered the range for the aircraft. However, by this point sales of the MD-11 had already been significantly impacted. The MD-11 was one of the first commercial designs to employ a computer-assisted pitch stability augmentation system that featured a fuel ballast tank in the tailplane, and a partly computer-driven horizontal stabilizer. Updates to the software package made the plane's handling characteristics in manual flight similar to the DC-10, despite a smaller tailplane to reduce drag and increase fuel efficiency.

After McDonnell Douglas merged with Boeing in 1997 the new company decided that MD-11 production would continue, though only for the freighter variant. However, in 1998 Boeing announced they would end MD-11 production after filling current orders. The last passenger MD-11 built was delivered to SABENA in April 1998. Assembly of the last two MD-11s were completed in August and October 2000; they were delivered to Lufthansa Cargo on February 22, and January 25, 2001 respectively. Production ended because of lack of sales, resulting from internal competition from comparable aircraft, such as the Boeing 777 and Boeing 767-400 and external competition from the Airbus A330/A340.

McDonnell Douglas and later Boeing performed studies on the feasibility of removing the tail engine and making it a twin-engine plane, but nothing came of it. McDonnell Douglas originally projected that they would sell more than 300 MD-11 aircraft, but only 200 planes were built. The MD-11 was assembled at McDonnell Douglas's Douglas Products Division in Long Beach, California (later Boeing's facility).

Design

The MD-11 is a medium- to long-range widebody airliner, with two engines mounted on underwing pylons and a third engine at the base of the vertical stabilizer. It is based on the DC-10, but features a stretched fuselage, increased wingspan with winglets, refined airfoils on the wing and tailplane, new engines and increased use of composites. The winglets are credited with improving fuel efficiency by about 2.5%. The MD-11 has a smaller empennage than the DC-10 it is based upon.

The MD-11 features a two-crew cockpit that incorporates six interchangeable CRT-units and advanced Honeywell VIA 2000 computers. The cockpit design is called Advanced Common Flightdeck (ACF) and is shared with the Boeing 717. Flight deck features include an Electronic Instrument System, a dual Flight Management System, a Central Fault Display System, and Global Positioning System. Category IIIb automatic landing capability for bad-weather operations and Future Air Navigation Systems are available.

The MD-11 incorporates hydraulic fuses not included in the initial DC-10 design, to prevent catastrophic loss of control in event of a hydraulic failure.

Variants

The MD-11 was manufactured in five variants.

  • MD-11 (131 built): the Passenger variant, sometimes referred to as MD-11P, was produced from 1988 to 1998. It was the first version on offer at launch of the aircraft in 1986, and was delivered to American Airlines (19), Delta Air Lines (17), Swissair (16), Japan Airlines (ten); KLM (ten), and other airlines with fewer aircraft.
  • MD-11C (five built): the Combi was the third variant on offer at launch in 1986 and was designed to accommodate both passengers and freight on the main deck, which featured a rear cargo compartment for up to ten pallets, each measuring 88 by 125 inches (2.2 m × 3.2 m) or 96 by 125 inches (2.4 m × 3.2 m). The main deck cargo compartment was accessible by a large rear port side cargo door, which measured 160 by 102 inches (4.1 m × 2.6 m). The main deck cargo volume was 10,904 cubic feet (308.8 m3). Additional freight was also carried in below-deck compartments. The MD-11C could also be configured as an all-passenger aircraft. All five aircraft were manufactured between 1991 and 1992 and delivered to Alitalia, the only customer for that variant. In 2005 and 2006 the airline converted them to full-freighter configurations to be operated by Alitalia's cargo division. Following that division's closure, the five aircraft were returned to their lessor in January 2009.
  • MD-11CF (six built): the Convertible Freighter variant was launched in 1991 by an order from Martinair for three aircraft plus two options. The MD-11CF feature a large forward port side cargo door (140 by 102 inches (3.6 m × 2.6 m)) located between the first two passenger doors, and can be used in an all-passenger or in an all-cargo configuration. As a freighter, it can transport 26 pallets of the same dimensions (88 by 125 inches (2.2 m × 3.2 m)) or 96 by 125 inches (2.4 m × 3.2 m)) as for the MD-11C and MD-11F for a main deck cargo volume of 14,508 cubic feet (410.8 m3) and offers a maximum payload of 196,928 pounds (89,325 kg). All six MD-11CFs were delivered to Martinair (four) and World Airways (two) during 1995. The two World Airways aircraft have been converted to freighter-only in 2002.
  • MD-11ER (five built): the Extended Range version was launched by the manufacturer at the Singapore Air Show in February 1994. The MD-11ER incorporates all the Performance Improvement Program (PIP) options, including a maximum takeoff weight of 630,500 pounds (286,000 kg) and an extra fuel tank of 3,000 US gallons (11,000 l)) in the forward cargo hold to offer a range of 7,240 nautical miles (13,410 km), an increase of 400 nautical miles (740 km) over the standard passenger variant. MD-11ERs were delivered between 1995 and 1997 to Garuda Indonesia (three) and World Airways (two). As of February 2007, only one Finnair MD-11ER has been converted to MD-11 with the removal of the extra fuel tank.
  • MD-11F (53 built): the Freight transport aircraft was the second variant on offer at launch in 1986 and was the last and longest (1988–2000) manufactured version. The all-cargo aircraft features the same forward port side cargo door (140 by 102 inches (3.6 m × 2.6 m)) as the MD-11CF, a main deck volume of 15,530 cubic feet (440 m3), a maximum payload of 200,151 pounds (90,787 kg) and can transport 26 pallets of the same dimensions (88 by 125 inches (2.2 m × 3.2 m) or 96 by 125 inches (2.4 m × 3.2 m)) as for the MD-11C and MD-11CF. The MD-11F was delivered between 1991 and 2001 to FedEx Express (22), Lufthansa Cargo (14), and other airlines with fewer aircraft.

MD-11 Boeing Converted Freighter (BCF) - Boeing and its group of international affiliates offer a conversion of used passenger airliners into freighters. The MD-11BCF is one of the models offered.

Note: Some or all the features of the MD-11ER, including the higher MTOW of 630,500 lb (286,000 kg), part or all of the PIPs aerodynamic improvements packages and composite panels were fitted to later built MD-11s (except the extra fuel tank), and could be retrofitted to any of the variants, except for the PIP Phase IIIB larger aft engine intake. Some airlines, such as Finnair, Martinair and FedEx have made the structural changes required to allow their aircraft to have the higher MTOW. Swissair's 16 newly delivered aircraft were retrofitted with all the features except for the extra fuel tank and were so-designated MD-11AH for Advanced Heavy.

Operators

In July 2013, 166 MD-11 aircraft (all variants) were in commercial service, with FedEx Express (64), UPS Airlines (38), Lufthansa Cargo (18), World Airways (4), KLM Royal Dutch Airlines (6), EVA Air (6), and other operators with fewer aircraft of the type.

Most of the airlines who ordered the MD-11 for their long-haul passenger flights had replaced it with Airbus A330, A340 and Boeing 777 aircraft by the end of 2004. Some carriers converted their MD-11s to freighters such as China Eastern Airlines and Korean Air . Korean Air announced as early as December 1994 its intention to convert its five passenger MD-11s to freighters for medium-range cargo routes. In 1995 American Airlines agreed to sell its 19 aircraft to FedEx, with the first MD-11 being transferred in 1996. Japan Airlines (JAL) announced the replacement of its 10 MD-11s in 2000; these aircraft were being converted into freighters and sold to UPS.

In February 2007 TAM Linhas Aéreas began operating the first of three leased MD-11s in intercontinental service following a 2006 order for four 777-300ERs to be delivered in 2008. In May 2007, Finnair announced the sale of their last two MD-11s to Aeroflot-Cargo to become part of the Russian airline cargo fleet in 2008 and 2009. Varig retired its MD-11s in 2007 after sixteen years of service. KLM is the last airline operating the MD-11 in passenger configuration on regular intercontinental flights. They are to be phased out by late 2014.

Two MD-11s were also operated in a VIP configuration, one by Saudia Royal Flight for members of the Royal family, and one by Mid East Jet for ASACO Aviation, both are now stored.

Accidents and incidents

As of November 2010, the MD-11 has been involved in 13 incidents, including eight hull-loss accidents, with 240 fatalities.

  • On April 6, 1993, China Eastern Flight 583, an MD-11 went into severe oscillations when a crew member accidentally deployed the slats during cruise flight over the Pacific Ocean near the Aleutian Islands. Two passengers ultimately died.
  • On July 31, 1997, FedEx Flight 14, MD-11 N611FE, crashed during a landing at Newark Liberty International Airport, New Jersey. The aircraft flipped onto its back and subsequently burned, following a landing attempt from an unstabilized flare.
  • On September 2, 1998, Swissair Flight 111, HB-IWF, crashed into the Atlantic Ocean while en route from New York City to Geneva, Switzerland. All 229 people on board perished. The cause of the crash was determined to be a fire caused by improper wiring of passenger entertainment system units added for Swissair. The fire started at the front of the aircraft and quickly grew uncontrollable, attributed partly to the poor flame retardant properties of its metalized mylar insulation.
  • On April 15, 1999, Korean Air Cargo Flight 6316, MD-11, registration number HL7373, crashed shortly after takeoff while operating cargo flight KE6316 from Shanghai Hongqiao International Airport to Seoul. After takeoff, the flight was cleared to climb to 1,500 meters (4,900 feet). The aircraft climbed to 4,500 feet (1,400 m). Due to confusion on the flight deck, the captain thought that the aircraft was too high and needed to go to 1,500 ft (460 m). The captain then pushed the control column abruptly forward causing the MD-11 to enter a rapid descent that they were unable to recover from. All three occupants on board and five people on the ground were killed.
  • On August 22, 1999, China Airlines Flight 642, an MD-11 operated by subsidiary Mandarin Airlines, crashed while landing at Hong Kong airport during a typhoon that exceeded the plane's crosswind specifications, also flipping onto its back and burning. Three passengers were killed.
  • On October 17, 1999, FedEx Express Flight 87, MD-11 N581FE, was written off after landing at Subic Bay International Airport, Philippines. The aircraft was operating from Shanghai Hongqiao International Airport. Upon landing, the aircraft rolled down the whole length of the runway before plunging into the bay where it was completely submerged except for the cockpit. An excessive approach and landing speed was pointed out as probable cause of the accident.
  • On March 23, 2009, FedEx Express Flight 80, MD-11F N526FE, crashed at Narita International Airport, Japan while landing in windy conditions. Airport surveillance video showed the aircraft becoming airborne again after the first touchdown, then impacting nose-first the second time and turning onto its left side, erupting into flames; the impact flipped the aircraft upside-down. The aircraft finally came to rest some distance left of the runway. The two flight crew members were killed.
  • On November 28, 2009, Avient Aviation Flight 324, MD-11F, registration Z-BAV (c/n 48408), crashed on takeoff from Shanghai Pudong International Airport on a flight to Bishkek-Manas International Airport, Kyrgyzstan with the loss of three lives. The aircraft was written off.
  • On July 27, 2010, Lufthansa Cargo Flight 8460, a MD-11F, crash-landed in Riyadh, Saudi Arabia. The two pilots are reported to have survived.

Safety issues

The MD-11 has had problems with its flight control systems, problems that have resulted in multiple accidents and incidents since the aircraft's introduction. The initial design of the slat/flap lever in the cockpit was conducive to accidental dislodgement by crew in flight. The defect has been corrected since 1992. In the early 2000s, Boeing improved the flight control software at the urging of the FAA to reduce the possibility of violent unintentional pitch movements.

In an effort to improve fuel efficiency, McDonnell Douglas designed the MD-11’s center of gravity to be much further aft than other commercial aircraft. This significantly reduces the margin for error during the takeoff and landing phases. A number of operators have introduced special training to assist crews in safely handling the MD-11's critical phases of flight.

    FAQ

    I don't see my comments any more!

    Please note that each page has it's own comment entry. So, if you enter a comment i.e. on the B-747, you will only see it on that related page.

    General comments are accessed via the "BLOG En" button.

    Comments are moderated, so please allow some delay before they appear, specially if you are outside Europe.

    Menus are developing below the page, because they are too long!

    But they remain accessible, for example by scrolling the mouse wheel, or with your finger (on the menu) on a smartphone or tablet.

    I see adds on all videos.

    Use a good free add remover software.

    The site is loading random pages at startup.

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    General

    Bilingual website

    You can change the language by clicking on the flag in the upper left or via "Options" in the central menu. Of course, the videos remain in the language in which they were posted ...

    Browser compatibility

    The site is not optimized, or even designed to run on older browsers or those deliberately deviating from standards. You will most probably encounter display issues with Internet Explorer. In this case, it is strongly recommended installing a modern (and free!) browser that's respecting the standards, like Firefox, Opera, Chrome or Safari.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
