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 m 3 ), 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.
Undeveloped variants
After ending the MD-12 program, McDonnell Douglas focused on 300–400-seat MD-11
derivatives. At the 1996 Farnborough International Air Show, the company presented
plans for a new trijet with high-seating and long-range named “MD-XX".
It was offered in the MD-XX Stretch and MD-XX LR versions. The MD-XX Stretch version
was to have a longer fuselage than the MD-11 and seat 375 in a typical three-class
arrangement. The MD-XX LR was to have a longer range and be the same length as the
MD-11; it was to have typical three-class seating for 309. However, the MDC board of
directors decided to end the MD-XX program in October 1996, because the financial
investment was too large for the company
