EVALUATION OF A LINEAR WASHOUT FOR SIMULATOR;MOTION CUE PRESENTATION DURING LANDING APPROACH

摘要

The comparison of a fixed-base versus a five-degree-of-freedom motion base simulation (the heave cue was not presented) of a 737 conventional take-off and landing (CTOL) aircraft performing instrument landing system (ILS) landing approaches has been used to evaluate a linear motion washout technique. The fact that the pilots felt that the addition of motion increased the pilot workload and this increase was not reflected in the objective data results, indicates that motion cues, as presented, are not a contributing factor to root-mean-square (rms) performance during the landing approach task. Subjective results from stand¬ard maneuvering about straight-and-level flight for specific motion cue evaluation revealed that the longitudinal channels (pitch and surge) and possibly the yaw channel produce accept¬able motions. The roll cue representation, involving both roll and sway channels, was found to be inadequate for large roll inputs, as used for example, in turn entries.
