Abstract:On the basis of ensuring the safety of the aircraft, the cabin comfort is the main consideration of the aircraft manufacturers and airlines. After discussing the definition of cabin comfort and the related theories of comfort process, three major external factors that affecting passenger comfort, etc. environment factors, passenger activities and social intercourse, are thoroughly analyzed and the priority of the factors are ranked. Based on the principle of Analytic Hierarchy Process, the evaluation method of a civil aircraft cabin comfort is proposed. The complete evaluation index system of cabin comfort is constructed, which contains 21 specific indicators in five subjects that is seats, IFE equipment, environment, passenger activities and subjective feelings. In order to facilitate comfort evaluation, the specific scoring criteria of subjective and objective comfort indicators are elaborated by using five-grade scoring criteria. Finally, the method is validated on the cabin mockup. The validation results show that the method is reasonable and simple, and can solve the problem of comfort evaluation of aircraft cabin.
