Abstract

This paper describes an experiment conducted to investigate the effects of roll-sway motion cueing algorithms on perceived simulator motion fidelity in a lateral repositioning task. The aims of the investigation were split into two primary objectives. Firstly, to repeat a previous roll-sway experiment conducted on the same simulator facility with the same aircraft model and motion drive algorithm, but with a different pilot, to determine if the results were repeatable. Secondly, to introduce an alternative motion drive algorithm. In the original roll-sway investigation the classical washout algorithm was used throughout the experiment. During the current experiment a comparison was made between the classical washout algorithm and the recently developed Lateral Manoeuvring Motion algorithm. The findings of the current experiment are in remarkably good agreement with those of the previous roll-sway experiment, particularly in terms of pilots’ subjective impressions of simulator fidelity. The results confirm that the roll-axis motion-filter break frequency has a strong influence on perceived motion fidelity, at the two break-frequencies tested in both experiments and at an intermediate break frequency tested in this experiment. Pilot opinion of the motion cues provided by the Lateral Manoeuvring Motion algorithm were very positive, although the trends in subjective and objective measures, observed while changing the motion filter coefficients, were not as clear or compelling as they were for the classical washout scheme. To the authors’ knowledge this is the first time that the Lateral Manoeuvring Motion algorithm has been systematically tested for a helicopter roll-sway task on a short-stroke motion platform.
