With the development of aircraft technology and the improvement of living standards, airplanes have gradually become one of the mainstream modes of transportation, and the comfort of the cabin environment has also been gradually valued. This article mainly focuses on the factors influencing the comfort of civil aircraft cabins. Through literature research, the main environmental parameter requirements of aircraft cabins, measured cabin environmental parameters during aircraft operation, and subjective evaluation of comfort are studied and analyzed. Research has found that there is significant inconsistency between standards for cabin environmental parameters, and existing standards do not directly reflect the aircraft cabin comfort. By analyzing the measured parameters and indicator requirements of the aircraft, as well as subjective evaluation values, it is found that the overall evaluation of the cabin environment is ‘relatively satisfactory’, and there is still a distance from ‘satisfactory’, indicating that there is still room and necessity for improvement in the cabin environment. For passengers, there are slight differences in the results of different questionnaire surveys, but all show that noise is the most unfavorable factor affecting overall passenger satisfaction, with wind speed and light having the least impact, while air pressure, air quality, and temperature still have some influence. For the crew, relative humidity is the most unfavorable environmental factor, followed by air quality and noise, but there is currently less research on the comfort of the crew. The results of this study can provide reference for the development direction of aircraft comfort optimization and improvement technology.
