Measurement of environment parameters and investigation of passengers’ comfort in domestic aircraft cabin

Aiming at the current situation that being short of the research results of aircraft cabin comfort at home, measures the aircraft cabin environment parameters in 14 flights, and conducts comfort investigation by questionnaire among 1 000 passengers. The results show that the passengers are generally satisfied with the cabin environment, but it still needs to be improved. Noise is the most unsatisfactory factor. Among the factors influencing overall satisfaction, air quality, noise, vibration and seat comfort are comparatively important, while air pressure, airflow and temperature are weaker, and humidity is not significant.
