air bridge 3D Model

a jet bridge (also termed loading bridge, aerobridge / airbridge, air jetty, portal, passenger walkway or passenger boarding bridge) is an enclosed, movable connector which extends from an airport terminal gate to an airplane, allowing passengers to board and disembark without going outside. depending on building design, sill heights, fueling positions and operational requirements, it may be fixed or movable, swinging radially or extending in length.

prior to the introduction of jet bridges, passengers would normally board an aircraft by walking along the ground-level ramp and climbing a set of movable stairs, or up airstairs on aircraft so equipped. mobile staircases or \"ramp stairs\" are still employed at many airports around the world, particularly smaller airports and terminals supporting low cost carriers.

loading bridges provide all-weather dry access to aircraft jet bridge and enhance the security of terminal operations. 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. the \"cab\", located at the end of the loading bridge, may be raised or lowered, extended or retracted, and may pivot, in order to accommodate aircraft of different sizes.

the first jet bridge in the united states was installed on july 29, 1959 at san francisco international airport.
