Abstract : These experiments had two purposes: (a) to find out how fast and how accurately operators could extract bearing and range information from the VJ remote radar indicator when they used it in different ways, and (b) to provide information about ways of performing equipment appraisals. Two experiments were performed, each involving many thousands of separate data obtained under a variety of operating conditions. Throughout most of these experiments, the VF was used as the criterion of accuracy because it is inherently much more accurate than the VJ. In some of the analyses, comparisons were made of range (or bearing) differences between the reports turned in from two VJs on identical targets. The latter is a measure of how much two VJs will disagree when they report on identical targets. (Author)
