Faster loading can lead to lower airport charges, fewer delays and more passenger throughput for the airport, all factors which impact an airline's bottom line. The Airbus A380 is unique in that both of its two passenger decks have outside access doors and so using loading bridges for each deck is possible, having the advantage of faster aircraft loading (in parallel). This was, for example, originally adopted for most wide body gates at Amsterdam Airport Schiphol. In some designs, the second jet bridge would even extend over the aircraft wing, being suspended from an overhead structure. In theory, this allows for faster disembarking of larger aircraft, though it is quite common, especially on aircraft such as Boeing 747s and Boeing 777s, to use one bridge for only passengers in first class and/or business class, while the other bridge is for the use of passengers in economy class. Some airports with international gates have two or even three bridges for larger aircraft with multiple entrances. As such, jet bridges provide enhanced access to aircraft for passengers with many types of disabilities and mobility impairments, as they may board and disembark without climbing stairs or using a specialized wheelchair lift. Additionally, many models offer leveling devices for the portion of the floor that makes contact with the aircraft this allows passengers to slowly transition from level aircraft floor to sloping jet bridge floor. The cab is provided with an accordion-like canopy, which allows the bridge to dock with aircraft with differing shapes, and provide a nearly weather-proof seal. These motions are controlled by an operator's station in the cab. The cabin, at the end of the loading bridge, may be raised or lowered, extended or retracted, and may pivot, to accommodate aircraft of different sizes. They are often permanently attached at one end by a pivot (or rotunda) to the terminal building and have the ability to swing left or right. Jet bridges provide all-weather dry access to aircraft and enhance the security of terminal operations. The first operational "Aero-Gangplank", as it was dubbed by inventor Lockheed Air Terminal, was installed by United at Chicago's O'Hare Airport in 1958. United Airlines tested an early prototype "Air Dock" in 1954. Mobile staircases or "ramp stairs" are employed at many airports around the world, particularly smaller airports and terminals supporting low cost carriers.
