Study on pilot attention allocation model based on fuzzy theory

Quantitative research of pilot attention allocation mechanism is required in aircraft human-machine interface optimization design and pilot flight performance evaluation. After making a comprehensive consideration of several factors, including information importance, information visual coding, information processing depth and human errors, pilot attention allocation model based on fuzzy theory is built. In order to make verification of this model, a head-up display (HUD) simulation model used to display flight information is developed on the basis of flight simulator. After setting the importance membership degree for different HUD information object according to its priority level under two flight modes, the key-press response experiment and eye-movement tracking experiment are designed and carried out for model confirmation. The experiment results are shown to be in good agreement with theoretical model and the effectiveness of the pilot attention allocation model based on fuzzy theory is confirmed.
