Abstract: To analyse the difficulty of flight tasks, a novel method was presented in this paper using pupil diameter of pilots. The proposed method integrated ensemble empirical mode decomposition (EEMD) and ratio of high to low frequency wavelet coefficients energy to identify pupil data under different tasks from 5 crews. Compared to the extraction method using wavelet energy entropy, the proposed method got more obvious difference between manual departure and standard instrument departure. The results indicated that…
