Abstract : A study was conducted to determine which coding systems (used to highlight critical and supercritical events) on a threat-warning display would lead to optimal performance in terms of identifying and locating such events, and determine the best means of presenting range information. Four coding systems were used, each with three range presentations: a conventional map, an expanded inner range, and an exponential display. A 30-minute simulated air penetration mission against two heavily defended complexes was flown by 24 subjects. During the mission the subjects were required to perform a symbol identification task, a monitoring task and a tracking task. A symbology set is recommended as a result of the tests.
