An Investigation of Pattern Recognition of Aircraft Attitudes Indicator Displays.

摘要

Spatial disorientation accident statistics are reviewed,along with unsuccessful attempts to prevent these aircraft accidents. The lack of a theoretical basis for flight instrument design is noted. A systems approach to the problem is proposed,which requires a knowledge of the human visual system. It is suggested that attitude indicator displays,the interface between man and machine,should be designed to be compatible with an internal model of spatial position. Orientation in space by the use of flight instruments is identified as a pattern recognition problem. A Fourier transform model of the human visual system is used to evaluate and classify attitude indicator displays. An algorithm is proposed for separating patterns. (Modified author abstract)
