Lockheed created the abbreviated fuselage L-1011 Tristar 500 as a long run, more modest limit subordinate of the Tristar 200.

Propelled in August 1976, the key progressions joined in the 500 over the standard L-1011s are the 4.11m (13ft 6in) shorter fuselage, more prominent takeoff weights, expanded fuel limit and all the more compelling Rb211-524 motors. The abbreviated fuselage lessens seating ability to a greatest of 330, 70 short of what the standard length Tristars, while the underneath deck galleys that had been a gimmick of the L-1011 family were supplanted with customary primary deck units.

Different enhancements incorporate improved wing-to-fuselage and fuselage-to-back motor admission fairings, programmed braking and programmed push control. Most have three, as opposed to four, entryways/crisis retreats on each one side of the fuselage. The outline progressions join together to give the 500 a greatest scope of 11,260km (6100nm), roughly 2000km (1300nm) more remote than the long extend 200.

The Tristar 500 first flew on October 16 1978 and entered administration with British Airways in May 1979.

Before long, the 500 likewise presented the dynamic aileron enhancements initially spearheaded on the Advanced Tristar, which was the first model Tristar fitted with various progressed gimmicks expected for prologue to the Tristar creation line. The Advanced Tristar joined expanded compass wings to lessen drag, with dynamic, programmed operation of the ailerons used to adapt to the expanded weight and air motion facilitating loads as opposed to fortifying the wing structure.

The initial 500 with dynamic ailerons and developed wingtips flew in November 1979 and conveyances of 500s with the new wing tip augmentation started the accompanying year, while in 1981 it turned into a standard peculiarity. Lockheed started retrofitting the dynamic aileron wingtip augmentation to all beforehand fabricated Tristar 500s from 1981. Creation stopped in 1983 after 50 had been fabricated, despite the fact that the last 500 was not conveyed until 1985.

In December 1982 Britain's Royal Air Force purchased 6 Tristar 500s from British Airways and contracted Marshall of Cambridge (Engineering) Ltd for the transformations. Four of them were changed over to tanker-transports as Tristar K1. The change includes the establishment of matched Hdus (Hose Drum Units) in the lower back fuselage, underfloor fuel tanks in the fore and rearward things compartments, including an extra 100,060lbs (45,385kg) of fuel, a shut circuit TV Polaroid to screen refueling, and military interchanges and route gear. The airplane are likewise furnished with a refueling test over the forward fuselage.

The main flight was made on July 9, 1985. As full traveler seating is accessible in the lodge, the K1 is an astounding air ship for squadron organizations, ready to refuel their airplane buzzing around and in the meantime convey squadron work force and supplies.

The other two airplane, and two of the K1s, were changed over to Tristar Kc1 with the same adjustments as the K1 however with an extra extensive payload entryway in the port side front fuselage, a cargo taking care of framework, and a fortified floor. They can convey load on beds and 35 travelers. The primary Kc1 was flown in 1988.

Three more, ex Pan Am, Tristar 500s were purchased in 1984, two of them serving as troop transport Tristar C2s. They hold the typical traveler seating and are not outfitted with a flight refueling test. It was wanted to change over the third one to a tanker K2, however these arrangements were relinquished and it was conveyed rather as a Tristar C2a, with another inner part, military flying, and the advanced autopilot supplanted by the same simple autopilot as fitted to the K1 and Kc1. The MTOW for all RAF Tristars was expanded to 540,000lbs (244,945kg). They present with 216 Squadron.

In late 2002 28 of the 50 Tristar 500s fabricated were in dynamic administration, 16 in air transport benefit, 3 as corporate transport, and 9 in RAF military administration.
