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.
This document supesedes the pre-existing SAE document on passenger boarding stairways (ARP836B). The ARP document had valuable information but it did not provide any guidance as to design consideratons. It simply presented information. As such this document would be better identified as an AIR. AIR6133 preserves the valuable information in the pre-existing document and updates the information based on the technology available.
