Abstract

This paper, which was presented at an Ordinary Meeting of the Institute held in London on 20 November, 1964, presents the results of a study on the interrelation of cruise fuel consumption, temperature and track selection in supersonic transport operations on the New York–London/Paris route. The range of temperature variations at S.S.T. altitudes over the North Atlantic for 26 months is illustrated and from this data period 24 cases are chosen to reflect extreme departures from standard and to give a seasonal distribution of such variation. The results of the application of a computerized nasa programme to these 24 cases to determine whether diversion from the great circle is warranted, in terms of economy of cruise fuel consumption due to existing temperature gradients over the area, are then discussed and illustrated.

The results of a general solution, taking into account all these considerations, applied to an additional 117 cases are also discussed and illustrated. Finally the influence of climb fuel consumption upon cruise fuel consumption and data requirements for temperature forecasts in climb and cruise are discussed.
