Lockheed L-1011-385-3 TriStar 500

The L-1011-500 TriStar was a three-engined wide-body aircraft. Announced in November 1975, this model first flew in 16 October 1978. It was designed by Lockheed as a true long-range aircraft with a shortened fuselage with less 4.1 m in comparison with standard TriStars. A larger wingspan and active ailerons provided a higher MTOW. Other design changes included more powerful Rolls-Royce engines (50,000 lbs), a noise-reducing Frisbee fairing (named after the Lockheed engineer Lloyd Frisbee) below the center engine intake, shorter wing-to-fuselage fairings, digital autopilot and FMS. The retractable tailskid installed on previous versions was removed since the fuselage length is shorter. The L-1011-500 didn't have the lower galley - to allow for more cargo space - and the front cargo door also was redesigned to be larger. Only fifty L-1011-500 were built until the end of production in 1983.
