The Effect of Training on Accuracy of Angle Estimation.
Waller, T. Gary; Wright, Robert H.
This report describes a study to determine the effect of training on accuracy in estimating angles. The study was part of a research program directed toward improving navigation techniques for low-level flight in Army aircraft and was made to assess the feasibility of visually estimating angles on a map in order to determine angles of drift. Eighteen subjects were randomly divided into a control group and two training groups. One group was trained using angles drawn on plain white cards and the other group used angles drawn on both cards and tactical maps. The groups estimated the size of angles ranging from 1 degree to 18 degrees. After training, it was found that the test performance of the two training groups on map items was significantly superior to test performance of the control group; on card items there were no significant differences between the two training groups and the control group. There were no significant differences between the two training groups on either card items or map items. The authors conclude that visual estimation of angles on maps appears to be a feasible technique for determining angles of drift. (DT)
