![]() ![]() ![]() 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. History A jet bridge at El Dorado International Airport in Bogotá, Colombia Three jet bridges feeding a Lufthansa Airbus A380 at Frankfurt Airport in Frankfurt, Germany Video of jet bridge being moved to an American Airlines plane at Toronto Pearson International Airport in Mississauga, Ontario, Canadaīefore the introduction of jet bridges, passengers normally boarded an aircraft by walking along the ground-level ramp and climbing a set of movable stairs, or airstairs on aircraft so equipped. ![]() Similar devices are used for astronauts to enter spacecraft, which are installed in the appropriate height of the launch tower. The jetway was invented by Frank Der Yuen. Depending on building design, sill heights, fueling positions, and operational requirements, a jet bridge may be fixed or movable, swinging radially, and/or extending in length. Jet bridges at Denver International Airport in Denver, Colorado, United StatesĪ jet bridge (also termed jetway, jetwalk, airgate, gangway, aerobridge/ airbridge, finger, skybridge, airtube, expedited suspended passenger entry system (E-SPES), or its official industry name passenger boarding bridge ( PBB)) is an enclosed, movable connector which most commonly extends from an airport terminal gate to an airplane, and in some instances from a port to a boat or ship, allowing passengers to board and disembark without heading outside and being exposed to harsh weather. ![]()
