Abstract: In this paper,the influences of the psychological quality on the performance of aviation pilots in training are quantitatively analyzed by existing psychological evaluation systems.As the structural equation model is well-suited for a global analysis of complex interactions as well as quantitative analysis of their strength,therefore it is appropriate to apply the model to analyze the relationship between psychological quality and corresponding performance,in order to solve the dilemma arising in both integral analysis and quantitative measurement.Taking advantage of the merit that this model can be optimized,a more reliable quantitative analysis is achieved through optimizing the indicators of psychological quality.The results indicate that either the fit index (CMIN/DF=1.1 71)or the reliability index (Cronbachα=0.799)is superior to those in the original model,which in turn validates the success of the proposed model.Moreover,this model can quantitatively evaluate the path coefficient as well,which shows that the emotional quotient (EQ)has a significant impact onto both theoretical performance (the path coefficient is 0.87)and flight performance (the path coefficient is 0.66), while has a medium relevance (the path coefficient is 0.59)with the crisis response.The emotional quotient is part of the decisive factors for psychological quality,and abundant attention should be paid for the psychological selection of aviation pilots in training.It should be noted,however,that,this model is not applicable in real-time scenario,due to the limita-tion of its static nature.
