This SAE Aerospace Recommended Practice (ARP) outlines the design and functional requirements for aircraft passenger lifts, operated manually and self-propelled. The primary function of the lift described in this document is to act as an elevator between ground level and aircraft doorsills to a maximum of 144 in.
Despite several attempts to revise this document since it has been issued, it has not been possible to do it as the resources and the needed expertise were not available in the AGE-2C committee. Intent of the committee for a future revision would be to merge ARP5140, ARP5141, and AIR4652 under a single revised and updated document. Therefore, until the time comes when such revision can be done, the document is put in the "Stabilized" category.
