Boarding stairs, sometimes called boarding ramp or gangway in the case of ships, [1] are devices designed to safety standards, [2] which facilitate the access of passengers and crew to ships or on aircraft when no built-in stairs are available. Larger aircraft may use one or more fingers attached to the terminal building for passenger boarding, but boarding stairs are used when these are not available or it is impractical or too expensive to use them, [2]
