This study was conducted to determine an appropriate task with which to test alternative orientation display formats, and to test a preliminary set of audio orientation symbology sets. Participants were required to perform three tasks simultaneously. The first task was a visual search (target designation) task. The second task was a radar monitoring task. Both of these tasks were performed on a head-down display. The third task consisted of monitoring aircraft orientation on a head-up display. The third task employed the study’s one independent variable – orientation symbology sets. When performing the aircraft orientation task, orientation was displayed in three ways: visual only, visual plus discrete audio orientation information, and visual plus continuous audio orientation information. Performance measures on all three tasks were collected. Results showed that participants responded more quickly to changes in aircraft orientation with the presence of discrete audio orientation information. Lessons learned about the tasks chosen for this study and the audio display symbology sets are discussed.
