Zusammenfassung:The experiment deals with the effect of increasing the work load on the output of a single operator and PPI console. Work load was increased by increasing the number of targets on the scope face. The information obtained in the study is a necessary preliminary to the evaluation of the Cadillac III CIC system. A rationale for the evaluation of this system is presented. It was found that detection time for a new target was a positive exponential function of the number of targets on the scope face. When the number of reports made within a minute interval was considered as a function of the running time of the experiment, a cyclical relationship appeared; i.e., about 10 to 12 reports were made per minute. The number of plots made per unit time remained constant under varying loads. The average number of plots was found to be 5.26 per minute.
