Lockheed L-1011 TriStar 500 Long Range Widebody Airliner
The Lockheed L-1011 TriStar is a three-engine medium- to long-range widebody jet airliner for up to 400 passengers
produced by the US-American manufacturer Lockheed Corporation.
The L-1011 TriStar 500 (L-1011-385-3) is a long-range variant with shortened fuselage (-4,11m / 13ft 6in) and a capacity of
max. 315 passengers (typical 253). All other variants have a length of length 54,17m (177ft 8in) and a capacity of max. 400
passengers (typical 234). The TriStar was Lockheed's last commercial aircraft.
Much like the DC-10 (sans military involvement) the L1011 started with a request from American Airlines for a widebody
airliner smaller than a 747 that had similar, if not identical, range. The L1011, unlike its competitors, was a much more
optimized design. Though mechanics and engineers disliked an engine being hidden in an S-duct in the aft fuselage behind the pressure bulkhead, it was more aerodynamically efficient.
The Aircraft was one of the first to feature a truly independent autoland system (it was, indeed, the first aircraft the FAA certified for Cat-III-C autolandings), even automated descent
control. This aircraft was on the bleeding edge of technology. So advanced, in fact, that the original and long-term goals of
the L1011 were to manufacture it as a “jumbo twin”.
