Aircraft Overview

History

The original L-1011-1 first flew on 16 November 1970 and entered service with Eastern Air Lines in April 1972. Engine-development and financial problems at Rolls-Royce delayed the programme. Lockheed built 250 TriStars between 1968 and 1984.

Design

The TriStar incorporated automatic landing capability and direct lift control. Its wide cabin was offered with features such as a lower-deck galley. The original model was certified as L-1011-385-1.

Variants

The family includes the original-length L-1011-1, -100, -200 and -250, plus the shorter, longer-range L-1011-500. The reference dimensions shown here are for the L-1011-1.

Operations

Eastern Air Lines, Delta, Cathay Pacific, TWA, British Airways and Air Canada were among TriStar operators. A converted aircraft, Stargazer, has also served as an airborne launch platform for Pegasus rockets.
