There are many U.S. airports with gates that do not have loading bridges.  When loading bridges are not available, aircraft must be boarded or deplaned using mobile stairs or ramps from grade level. These means of aircraft access can be challenging, particularly for those with mobility issues.  In these situations, some passengers may need to be manually carried up or down boarding stairs.  This may lead to a compromise of passenger dignity, let alone an increased risk of injuries for all parties involved.  These issues are particularly relevant when accessing medium and large aircraft, which have higher door sills.

The objective of this research is to explore practical solutions (including new concepts) for providing a safe and dignified experience for passengers with mobility issues when boarding medium and large aircraft at gates without loading bridges.
