Six pilot studies were conducted to determine the effects of training on range estimation performance for aerial targets, and to identify some of the relevant variables. Observers were trained to estimate ranges of 350, 400, 800, 1,500, or 2,500 meters. Several variations of range estimation training methods were studied, including immediate knowledge of results after making an estimation, paired associate presentation of observed aircraft position with actual range information, and the use of an occluding object as a range estimation aid. Two variables that tended to influence performance were aircraft elevation and incoming-outgoing directions of flight.
