Research on Cabin Load Evaluation of Two Types of Transport Aircraft

Objective. To investigate the difference of cabin environment between a large transport aircraft (A) and a previous transport aircraft (B) and its impact on the workload of flight personnel by questionnaire, so as to provide reference for the formulation of aviation and health support measures. Methods. A self-administered questionnaire was used to conduct on-the-spot investigation. The grade data were tested by nonparametric test, with P < 0.05 as the statistical difference. Results. The results of cockpit environment investigation showed that there was no significant difference in the evaluation of cockpit noise and vibration changes between the two types of transport aircraft, but there was significant difference in the evaluation of cockpit temperature comfort, instrument airworthiness and control convenience between the two types of transport aircraft (Z = −3.136, P = 0.002; Z = −3.556, P < 0.001; Z = −3.556, P < 0.001); There was no significant difference in the effects of cockpit environment on hearing and vision between the two types of transport aircraft; there was significant difference in the evaluation of seat comfort between the two types of transport aircraft (Z = −2.395, P = 0.017). Conclusion. The noise and vibration of the cockpit environment of transport A have no obvious change compared with that of transport B, but the temperature comfort of the cockpit of transport A has been greatly improved; the instrument airworthiness and convenient control of the cockpit of transport A have been greatly improved compared with that of transport B; the influence of the cockpit environment of two types of transport on the hearing and vision of flight personnel is not obvious, and The comfort of the seats of transport A has been improved significantly compared with that of transport B.
