Sixteen military pilots flew simulated air-to-air and air-to-ground missions in a simulated fighter-attack cockpit. Three of the five color CRTs in the cockpit were capable of displaying retinal disparity and the major independent variable was presence or absence of disparity. Performance, workload, and opinion data were collected. A second objective of the study was to continue development of the display formats, which had evolved through earlier projects. The disparity results and the recommended format revisions are presented.

The only changes recommended for the HSF were to leave the cursor on the display full time, rather than having to call it up with a button stroke and to repeat the prediction line from the PSF on HSF. The CASS format worked fairly well, but the pilots suggested using words rather than symbols for the mission impact indications.
