Abstract: In the present study, three fighter pilots were monitored while performing routine flight training. ECG, respiration wave, body temperature, body movement and acceleration (Gz & Gx) were continuously measured and analyzed using a small recording device strapped around the chest. The flight parameters, critical events as well as the flight path of each flight were recorded using flight parameters recorder during the real flight and analyzed at the end of flight. The instantaneous heart rate and respiration rate at any flight instant can be determined through analyzing flight parameters recorded using flight parameters recorder. Time-domain analysis and frequency-domain analysis of short-time rapid HRV are carried out in different flight phases. This study provides a technique to analyze exactly in-flight psycho-physiological parameters and to measure mental workload dynamically.
