Lockheed L-1011-385-3 (TriStar 500)

The TriStar 500 is 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 TriStar 500 does not have the lower galley to allow for more cargo space and the front cargo door was redesigned to be bigger. Only fifty L-1011-500s were built until the end of production in 1983.
