British Airways Tri‐Star: Present and Future Available to Purchase

British Airways has for some time been operating TriStar ‐1 aircraft over a wide range of sector lengths and is currently planning the introduction of the ‐500 longer range variant in 1979. Development of the engineering aid maintenance organisation to support these wide‐body aircraft has progressed in parallel with the increase in the airlines' fleet, and has had to take account of the ‘Reliability’ and ‘Maintainability’ concepts formulated in the 1960's. Commonality of systems and components in the two models ordered by British Airways, and where possible, throughout the TriStar tange, is a significant factor in keeping the cost and complexity of operating different versions of the same aircraft within acceptable limits.
