  • This paper focuses on the objective discrimination and prediction of mental workload of the aircraft flight deck display interface. By three physiological measurement methods of event-related potentials (ERP), electrocardiograph (ECG) and electro-oculogram (EOG), as well as subjective evaluation and performance evaluation, both experimental measurement and mathematical modeling of mental workload were carried out under the same flight simulation task conditions. The experimental results indicate that as the mental workload increased, the peak amplitude of the mismatch negativity (MMN) at Fz significantly increased, while the peak amplitude of P3a at Fz, the standard deviation of normal-to-normal RR intervals (SDNN) value, and the eye blink numbers significantly decreased. Based on the results of experimental measurement, the Bayesian discrimination analysis method was employed to construct the mental workload discrimination model of the aircraft flight deck display interface. The integrated physiological model showed a higher accuracy in the discrimination and prediction of mental workload compared with NASA_TLX. Thus, this model provides not only a new approach for the objective and real-time discrimination and prediction of mental workload of the aircraft cockpit display interface, but also a new compliance verification tool for the human factor airworthiness certification of flight deck display interface of the new generation fighter aircraft and large passenger aircraft.
