In its initial version, the L-1011 TriStar (the Dash One) is designed for short/medium-haul routes—typically carrying 250/270 mixed-class passengers distances of from 300 to more than 3000 nm. A general arrangement is shown in Fig. 1. As indicated in Fig. 2, the L-1011-1 payload/range curve is placed between those of the DC-8-61 and the Boeing 747. It should be noted that both these aircraft are designed for long ranges and are suited only for operation from major airports. On the other hand, the TriStar has airport performance, in terms of field length, comparable to that of the much smaller short-range types, typified by the Boeing 727. This, in broad terms, illustrates the primary design objective of the Dash One. The dashed line on Fig. 2 shows the payload/range curve of the L-1011-2 which will, of course, have an airport performance at the heavier gross weights more in keeping with long-haul requirements.
