This SAE Aerospace Recommended Practice (ARP) is intended to recommend a minimum standard, for the design and manufacturer of a self-propelled, chassis mounted passenger boarding vehicle. The vehicle will permit safe operation while minimizing aircraft damage and personnel safety hazards associated with commercial aircraft boarding operations. The vehicle described is intended to be used for assisting wheelchair passengers and passengers with disabilities on and off aircraft with door sill heights of 60 in (152.4 cm) and above.
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.
