Abstract : The study consisted of two separate experiments. In both experiments private pilots drew solutions to navigation problems, using printed drawings of pictorial aircraft instrument displays. The purpose of the first experiment was to compare performances of the subjects in drawing the movement which would be made by the moving figure of the display throughout the solution of the problem, when the moving figure represented (1) the station, and (2) the aircraft. (When the station moved, the aircraft was represented at the center of the display and heading was always straight up the face of the display. When the aircraft moved, the station was in a fixed position.) Results of the first experiment showed that it took over seven times as long to work the station movement problems, with only one fifth of them correct, as it took to work the aircraft movement problems, with four fifths of them correct. The purpose of the second experiment was to compare performances of private pilots in drawing the figure movement for the solutions to navigation problems when the moving figure always represented the aircraft and in which there were different arrangements of two variables, namely, (1) the location of the fixed station, and (2) the orientation of the compass rose ('North' at the top of the display or 'North' not at the top).
