Abstract:

This research effort involved an experiment investigating the effect of asynchronous visual delays on simulator flight performance and the development of simulator sickness symptomatology. The SH-60B Vertical Takeoff and Land VTOL Simulator, part of the Navys Visual Technology Research Simulator VTRS program was used to investigate this issue. Twenty-five experienced pilots flew three 40- or 60-minutes sessions with two simulator tasks air taxi and slalom under each of the lag conditions. Pilots flew one session per day for three days with the lag condition changing each day. Objective and self-report indices were collected and, while results showed no difference between lag conditions, paper-and pencil illness ratings reflected a high initial incidence of illness 46 on Day 1 followed by rapid adaptation upon subsequent exposure. Simulator performance, however, was differentially affected by lag with the longest lag producing the worst performance. Finally, relationships between sickness indices, flight performance data, and other variables are presented and discussed along with observations, recommendations, and areas for future research.
