![]() ![]() The L-1011 TriStar's sales were hampered by two years of delays due to developmental and financial problems at Rolls-Royce, the sole manufacturer of the aircraft's engines. Post-production conversions for the L-1011-1 with increased takeoff weights included the L-1011-50 and L-1011-150. The original-length TriStar was also produced as the high gross weight L-1011-100, up-rated engine L-1011-200, and further upgraded L-1011-250. The shortened, longer range L-1011-500 first flew in 1978 and entered service with British Airways a year later. The original L-1011-1 first flew in November 1970 and entered service with Eastern Air Lines in 1972. The L-1011 TriStar was produced in two fuselage lengths. The aircraft has an autoland capability, an automated descent control system, and available lower deck galley and lounge facilities. Its trijet configuration has three Rolls-Royce RB211 engines with one engine under each wing, along with a third engine center-mounted with an S-duct air inlet embedded in the tail and the upper fuselage. The airliner has a seating capacity of up to 400 passengers and a range of over 4,000 nautical miles (7,410 km). It was the third wide-body airliner to enter commercial operations, after the Boeing 747 and the McDonnell Douglas DC-10. The Lockheed L-1011 TriStar, also known as the L-1011 (pronounced "El-ten-eleven") and TriStar, is an American medium-to-long-range, wide-body trijet airliner built by the Lockheed Corporation. ![]()
