Abstract
The primary purpose of this study was to determine the effectiveness of using color cathode ray tube (CRT) checklists and programmable multifunction switches to display warning/caution/advisory (W/C/A) information. This study compared three different display formats on speed and accuracy of recognition and execution of emergency procedures. The following three different W/C/A formats were tested: 1) Abbreviated title of the emergency written on a CRT [e.g., ELEC SYS/MAIN GEN], with the pilot using his knee pad checklist to complete the required steps, 2) Complete title with the checklist shown on a CRT, [e.g., MAIN GENERATOR FAILURE/ELEC RESET SWITCH- DEPRESS], and 3) Complete title with the checklist plus the pictorial switch layout, [i.e., CRT showing location of switch to be pressed.] Results showed that there is a definite advantage in using a CRT W/C/A checklist. Event time for the Abbreviated Title/Manual Checklist was significantly longer than either the Complete Title/CRT Checklist or the Complete Title/CRT Checklist with pictorials. However, there was no difference in event time between the latter two.
