| The present study investigated the effects of different display, hypothesis presentation, information presentation, and parameter presentation styles on pilot performance. It was hypothesized that performance would be maximal using picture-based displays, presenting hypothesis information as a composite, showing only out-of-tolerance parameter information, and when parameter information was displayed as a bargraph. The results of the study indicated that pilot performance was best when employing picture- and text-based displays, when fault hypotheses were displayed as composites. There were no differences in response times when picture- and text-based displays were compared. Subjects' performances were best when hypotheses were displayed as composites compared to when the individual hypotheses were displayed. The display of the out-of-tolerance parameter information resulted in faster overall pilot performances compared to the presentation of all relevant parameter information. There were no differences in performance when parameter information was presented as a bargraph compared to when it was presented as a numerical value. The findings are discussed and recommendations for future research are presented. |
