Four aspects of cabin research
Civil aviation aircraft; Cabin layout; Influencing factors; Configuration research

With the increasing proportion of China's civil aviation in people's lives, the layout of the aircraft cabin, as the area with the closest contact with passengers, has gradually become the focus of attention, which not only represents the overall technical level of the aircraft, but also shows the overall image of China's civil aviation development. Therefore, how to optimize the layout of civil aviation cabin, so as to fundamentally improve the disadvantages of the original layout of civil aviation cabin and optimize the composition of internal facilities such as emergency equipment has become the focus of attention at this stage. In this paper, the factors found in the previous aviation maintenance that will affect the layout of civil aircraft cabins are expounded and studied to help them ensure the layout effect as soon as possible and optimize the overall efficiency of the layout, thus promoting the development of civil aircraft in China in the future.

First, the influencing factors of civil aircraft cabin layout

According to the previous research, it can be found that in terms of civil aviation cabin layout, it is usually necessary to have certain safety and comfort at the same time, which makes the actual civil aviation layout more restrictive than other types of aircraft layout. Therefore, it can be considered that the factors affecting the layout of civil aviation cabins are a very complicated and comprehensive work. Combined with previous studies, it can be found that the main factors affecting the layout of civil aviation cabins are mostly concentrated in the following aspects:

(a) seaworthiness requirements

According to the previous research on the factors influencing the layout of civil aviation aircraft cabin, the actual airworthiness requirement is an important part of the actual cabin layout design. It is required that safe flight is the premise of the design during the cabin layout process, and flying is not allowed until it meets the standard of safe flight. As far as this influencing factor is concerned, there have been corresponding explicit provisions in the world, which not only clearly determine the maximum number of seats in the aircraft cabin and the number of emergency exits, but also clearly specify the number of crew and passengers. Among the influencing factors, the crew should pay attention to that this regulation not only requires the size and layout of public places such as passenger evacuation areas and doors, but also clearly stipulates basic parameters such as handrails and spacing. However, in the determination of this airworthiness standard, there is no clear division of the rest area of the crew. Therefore, in the actual cabin layout, the corresponding layout and maintenance should be carried out according to the actual needs.
