An investigation of flight simulation cueing synchronization requirements for the visual, roll motion, and lateral motion was conducted on the Vertical Motion Simulator (VMS) at NASA Ames Research Center. The unique displacement capability of the VMS was exploited by developing a piloted task such that the visual and motion cues matched closely for a baseline configuration. Pilots performed a lateral sidestep between two points 20 feet apart using a helicopter model designed to have satisfactory handling qualities. Since the VMS has in excess of 20 feet lateral travel, the task was simulated exactly. That is, the motion and visual cues had a one-to-one correspondence. Starting with the baseline simulation cueing configuration that had synchronous visual, roll, and lateral cues, time delays of 40 and 80 msec were introduced into the visual, roll, and lateral axes in a randomized matrix giving a total of 27 configurations. The baseline configuration was developed based on the current FAA helicopter simulator specifications for civil helicopter motion fidelity requirements, which has little objective data for its support. Six experienced test pilots from both government and industry rated all of the configurations. Objective and subjective data were taken that included handling qualities ratings, motion fidelity ratings, and perceptions of synchronization. Initial analysis of the data indicate support for aspects of the current FAA specifications on civil helicopter motion fidelity requirements, with some additional preconditions. Based upon a statistical analysis of the data, recommendations are made for permissible cueing delays and asynchronization.
