TECHNIQUES FOR LOW ALTITUDE NAVIGATION: DIRECTION ESTIMATION FROM TACTICAL MAPS.
Abstract
The objective was to study the effects of map scale, map reference point variables, and training on the ability of pilots to estimate direction using Army tactical maps for low-level navigation. Twenty-four experienced officer and warrant officer pilot personnel working with various map reference point conditions made direction estimates using 48 maps with a scale of 1:100,000 and 48 maps with a scale of 1:250,000. The effect of training was studied by using a test-train-retest-delay-retest procedure. Performance was measured in terms of absolute error, in degrees, between the estimated direction and the correct direction. Analyses showed that average error in direction estimation using tactical maps was reduced significantly by training, dropping from a mean of 6.1 degrees before training to 4.8 degrees after training. There were also significant differences in accuracy of direction estimates as a function of map scale, distance between reference points, and compass octant in which the reference points were located.
