Abstract
A function of North American Aerospace Defence (NORAD) in North Bay, Ontario is to identify all aircraft entering Canadian air space. The first step in performing this task is to detect visually the presence of aircraft from either radar or transponder information presented on display consoles. This challenging, real-world vigilance task was used in two experiments to investigate factors affecting detection latencies. Taken as a whole, the experiments revealed that (1) transponder tracks, with their unique symbology, were more easily detected than radar tracks; (2) performance varied as a function of geographic area of coverage; (3) the midnight shift was particularly sensitive to vigilance decrements; and (4) a 'vigilance decrement' effect can occur in a real world task, but this effect is not as strong as those reported in laboratory studies.
