McDonnell Douglas MD-11
Wide-body jet airliner · 1990
The McDonnell Douglas MD-11 is an American trijet wide-body airliner which was manufactured by McDonnell Douglas and later by Boeing. The MD-11 is the largest trijet ever built. Following DC-10 development studies, the MD-11 program was launched on December 30, 1986. Assembly of the first prototype began on March 9, 1988.
Its maiden flight occurred on January 10, 1990, and it achieved Federal Aviation Administration (FAA) certification on November 8. The first delivery was to Finnair on December 7 and it entered service on December 20, 1990. It retains the basic trijet configuration of the DC-10 with updated General Electric CF6-80C2 or Pratt & Whitney PW4000 turbofan engines.
Its wingspan is slightly larger than the DC-10 and it has winglets. Its maximum takeoff weight (MTOW) is increased by 14% to 630,500 lb (286 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 nautical miles [nmi] (13,200 km; 8,210 mi). It features a glass cockpit that eliminates the need for a flight engineer.
