The McDonnell Douglas MD-11 is an American tri-jet wide-body airliner manufactured by American manufacturer McDonnell Douglas (MDC) and later by Boeing. 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.
After liftoff, a speed V 2 will be called out, being the speed at which the aircraft is able to climb at a sufficient rate to reach its cruising altitude, and therefore at which the gear will be retracted. [2] Early or over-rotation can cause a tailstrike, which can damage the underside of the tail unless prevented by a protection device such ...
Three-engine aircraft such as the MD-11 and BN-2 Trislander do not have a V MCA2; a failed centerline engine has no effect on V MC. When two opposing engines of aircraft with four or more engines are inoperative, there is no thrust asymmetry, hence there is no rudder requirement for maintaining steady straight flight; V MCA s play no role ...
China Eastern Airlines Flight 583 was a commercial passenger flight from Shanghai, China, to Los Angeles, United States, operated by China Eastern Airlines.On April 6, 1993, the McDonnell Douglas MD-11 operating the flight experienced an in-flight upset due to a flight crew member inadvertently deploying the slats of the aircraft while the plane was cruising near the Aleutian Islands.
Seating plan B-150, the aircraft involved in the accident, painted in old China Airlines livery (circa 1992–93). The aircraft was a McDonnell Douglas MD-11 registered as B-150, which had been delivered to China Airlines in October 1992. The aircraft was powered by three Pratt & Whitney PW4460 turbofan engines.
Used instead of V R (in discussions of the takeoff performance of military aircraft) to denote rotation speed in conjunction with the term V ref (refusal speed). [19] V Ref: Landing reference speed or threshold crossing speed. [7] [8] [9] Must be at least 1.3 V S 0. Must be at least V MC for reciprocating-engine aircraft, or 1.05 V MC for ...
This aircraft would become the first L-1011 and first wide-body hull-loss as Eastern Air Lines Flight 401. TWA heralded the TriStar as one of the safest aircraft in the world in promotional literature in the 1980s when concern over the safety record of the McDonnell Douglas DC-10, flown by rival airlines, was at its peak.

X describes the aircraft manufacturer for which the engine is approved. A "0" stands for Boeing; "1" for Airbus; and "4" for the McDonnell Douglas MD-11. YZ denotes the certified thrust in US pounds (lbf) in pro-mile fraction. Example: A PW4090 identifies a PW4000 series engine certified for Boeing (777-200ER) and has a certified thrust of ...
