An investigation was undertaken to provide a human factors evaluation of an electroluminescent display designed for the presentation of around-the-base weather messages. Time and error data were obtained for 42 Air Force weather, GCA, and pilot personnel in responding to six questions for each of 50 weather messages, 25 of which were presented on an electroluminescent display and 25 by conventional teletype format. The few significant differences found do not warrant a conclusion that the electrolumescent format employed is inferior to the conventional teletype format. It is concluded that weather message information processing may be improved by the development of time and error normative data for a standard set of weather messages, thereby permitting the identification of high-error perhaps error-prone personnel, by training to improve the interpretation of visibility coding and more specifically, by an improved formating of fractions concerned with visibility. The suggestion for the development of normative data may have applicability for other military information systems.
