As the complexity of flight missions continues to increase,sending a timely warning or providing assistance to pilots helps to reduce the probability of operational errors and flight acci-dents.Monitoring pilots\' physiological data,real-time evaluation of mission load is a feasible tech-nical way to achieve this.In this paper,a set of flight tasks including aircraft control,human-computer interaction and mental arithmetic tests are designed to simulate five mission loads at dif-ferent flight difficulty levels.A sensitivity analysis method based on a comprehensive test is pro-posed to select a set of sensitive physiological factors.Then,based on the SVM hierarchical combination classification method,the pilot mission load real-time evaluation model is established.The test results show significant differences in EMG,respiration rate (abdomen),heart rate,blood oxygen saturation,pupil area,fixation duration,number of fixations,and saccades.The high accu-racy obtained from experiments proved that the proposed real-time evaluation model is applicable to meet the requirements of real working environments.The findings can provide methodological references for mission load evaluation research in other fields.
