McDonnell Douglas MD-11 - Variants

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 (10); KLM (10), and other airlines with fewer aircraft.
• MD-11C (5 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 (6 built): the Convertible Freighter variant was launched in 1991 by an order from Martinair for 3 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 twenty six 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 (4) and World Airways (2) during 1995. The two World Airways aircraft have been converted to freighter-only in 2002.

• MD-11ER (5 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 Take-Off 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 (3) and World Airways (2). 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.
