This paper examines the requirement for a new type of display for the pilot navigator of the S.S.T. (supersonic transport). The author holds that inductive reasoning, which is the basis of manual navigation techniques, should not be dispensed with and the benefits of automatic systems will not be achieved until a similar awareness of the processes going on about the navigator can be reproduced. A well-designed display system might have this potential.

The ideas behind this paper were first described at the Annual Meeting of the American Institute of Navigation in Long Beach, California, in June 1965 and further developed at a meeting of the Deutsche Gesellschaft für Ortung und Navigation held at Munich in August of 1965.
