本SAE航空航天信息报告（AIR）分为不同类别，以方便识别。本文件旨在为乘客登机梯的设计和选择提供某些标准。提出的标准仅限于影响乘客安全的因素，并在适用情况下与建筑专业在楼梯设计方面的实践相协调。乘客楼梯的综合设计要求见下文2.1.3、2.1.4和2.1.5中列出的行业文件。推荐做法适用于移动式可变高度楼梯和飞机机身内置式固定高度楼梯。

This SAE Aerospace Information Report (AIR) is broken into various categories for convenience and ease of identification. It is the purpose of this document to provide certain criteria for the design and selection of stairways, for the boarding of passengers onto an aircraft. The criteria presented are limited to those factors which affect the safety of the passengers and are coordinated, where applicable, with the practices of the architectural profession, with respect to the design of stairways. Comprehensive design requirements for passenger stairs can be found in the industry documents listed under 2.1.3, 2.1.4, and 2.1.5 hereafter. The recommended practices are applicable to both mobile variable-elevation type stairways and to fixed-elevation stairways of the type built into an aircraft fuselage.
