Abstract
When a loading bridge is connected to a small aircraft to allow passengers to board or deplane, a large size difference exists between the aperture of a loading bridge and the entry/exit hatch of a small aircraft; the loading bridge aperture being larger than the aircraft hatch. Accordingly, the size difference creates a potentially dangerous gap. The extensible platform on an extensible passenger loading bridge is for alleviating the gap and as such for providing a safe pathway to passengers when they board or deplane.
