The purpose of this paper is to explore one part of the 1972 commercial air transport picture. New jet engine and aircraft technology will be available which offers substantial advantages in operating economics. A major portion of the improvement will come by way of the engine redesigns. Higher bypass ratios, higher turbine inlet temperatures, and substantially advanced structural concepts point in the direction of lower direct operating costs.An analysis is made using these “new technology” engines on older fleets of large jet transports. Results show that the domestic operators have little to gain. Longer range, intercontinental operators may find the engine conversion attractive for some route segments where range is critical. Engine maintenance costs, among other costs, associated with reengining are considered. Finally, using these results, an estimate is made of an airplane size which will maximize the cost-reduction potential of the engines.
