The Lockheed L-1011 Tristar also knows as L-1011 (L-ten-eleven), which was named as Tristar after a staff competition, is an American medium-to-long-range, wide-body trijet airliner that is to date the sole commercial jet transport produced by Lockheed Corporation. The Lockheed Tristar was the third wide-body airliner to enter commercial operations, and even though it encountered early financial and development issues, specifically with the engine, the airliner went on to secure an outstanding record in service for its reliability, economy of operation, and low noise emissions.

In 1975, the second production variant (after the L-1011-1) of the L-1011 Tristar designated as the L-1011-100 with Federal Aviation Administration certification L-1011-385-1-15 took to the skies for the first time. In May 1974, launch orders for the aircraft were placed by Saudia and Cathay Pacific Airways, for two each. After a year, in June 1975, aircraft deliveries started. The L-1011-100 version was also acquired by some airlines with longer-range flights such as Trans World Airlines (TWA), Air Canada, British European Airways which joined with British Overseas Airways Corporation (BOAC) to establish British Airways. The first two of this version with serial numbers 1110 and 1116 were delivered new to Saudia. The aircraft has the same fuel capacity as the L-1011-1 with FAA certification L-1011-385-1-14.

The L-1011-100 has an external length of 54.17 meters, a height of 16.87 meters, and a fuselage diameter of 5.97 meters. It has a wingspan of 47.35 meters and a wing area of 321.1 square meters. It is designed with a new center fuel tank and higher gross weight compared with the first version. The travel range is increased by around 810 nautical miles. The aircraft is equipped with a highly advanced autopilot system, inertial navigation system, direct lift control system, and autoclave system.

The aircraft is powered by three Rolls-Royce RB211-22 with a maximum thrust of 42,000 lbf each. The maximum cruise speed is 515 knots, the service ceiling is 4200 feet, and the rate of climb is 2,800 feet per minute.
