The McDonnell Douglas MD-11 is an American tri-jet wide-body airliner manufactured by American McDonnell Douglas (MDC) and later by Boeing. Following DC-10 development studies, the MD-11 program was launched on December 30, 1986. The first delivery was to Finnair on December 7, 1990.
It retains the basic trijet configuration of the DC-10 with updated GE CF6-80C2 or PW4000 turbofan engines. It has a slightly wider wing with winglets, and its MTOW was increased by 14% to 274 t.
Its fuselage is stretched by 11% to 202 ft (61.6 m) to accommodate 298 passengers in three classes over a range of up to 7,130 nmi (13,200 km). It features a glass cockpit that eliminates the need for a flight engineer. Some MD-11 freighters were built, but many more are converted MD-11 passenger aircraft.
