ABSTRACT
Objective To resolve the problems of comprehensive evaluation on pilot's situation cognition basing on studying the mission situation. Methods The model of fuzzy comprehensive evaluation on pilots' situation cognitive was established on the basis of researches on concepts and methods of environmental quality evaluation in environment science.Results On the basis of theoretical consideration and analysis of experiments, the state of pilot's situation cognition was revealed preliminarily.Conclusion It is showed that the fuzzy comprehensive evaluation method on pilot's situation cognition can provide real and complete flight cognitive information. It is reliable basis for pilot's efficacy of training and flight safety.
ABSTRACT
Objective To establish a system to evaluate the mental workload on visual display interface in airplane cockpit after synthesizing three kinds of mental workload assessment techniques,i.e.main task measure method,physiology measure method and subjective evaluate method.Methods The evaluation indices of every kind of assessment techniques was defined,and the amount of each index through experiment and subjective inquiry was gained,weighted average was calculated and a quantification evaluation value of each kind of evaluation methods was got.At last,with weighted calculation of above three evaluation values,the evaluation value of mental workload on visual display interface in airplane cockpit was obtained.Results In M kinds of different designs of visual display interface in airplane cockpit,the synthetic evaluation value of one design was the smallest and the mental workload of this design was the smallest.The design of the smallest mental workload was chosen prior as the final scheme of visual display interface in airplane cockpit.Conclusion The evaluation system is combined with present main evaluation methods of mental workload and utilizes their advantages.The evaluating result can be quantified more directly and clearly.With this evaluation system,the mental workload can be evaluated during the design of visual display interface of airplane cockpit and the best scheme can be confirmed.
