Long range TriStar for British Airways

Scheduled to enter service in 1979, British Airways ‐500 TriStars will be the first of this variant in operation and will be used on the airline's longer routes (up to 5,260 n miles). They will be suitable for such sectors as London‐Los Angeles, Sydney‐Hong Kong and New York‐Buenos Aires, carrying 246 passengers. The ‐500 has been designed to take advantage of a high degree of commonality with earlier TriStar models and from a maintenance standpoint, 95 per cent of the air‐frame spares and 100 per cent of the engine spares are the same as the ‐200 Series.
