Investigation into Pilot Perception and Control During Decrab Maneuvers in Simulated Flight

摘要

An experimentwas conducted in the SIMONAResearch Simulator atDelftUniversity ofTechnology to investigatenthe influence of sway, roll, and yawmotion cues on pilot performance, control, andmotion perception during decrabnmaneuvers. In the experiment, six pilots were instructed to perform manual decrab maneuvers in heavy crosswindnconditions with a Cessna Citation 500 model. The contributions of yaw, roll, and sway motion stimuli were variednsuch that their effects on objectivemeasures and subjective ratings could be examined. The results of this experimentnshow that yaw motion had a positive influence on performance in terms of lateral touchdown distance from thenrunway centerline. Roll motion significantly decreased roll rate variations during decrab. High workload and thenrelatively low intensity of lateral motion cues led to the fact that pilots were unable to give consistent fidelity ratings.nThis result emphasizes the need for an objective and quantifiable method to determine motion fidelity for suchnmaneuvers. Pilot models can possibly be used to further investigate the influence of different motion cues in thesentransient control tasks.
