ABSTRACT:
A system for aligning an aircraft-engaging end of a passenger boarding bridge to a doorway along a lateral surface of an aircraft includes an imager disposed at a location that is remote from the aircraft for capturing an image of a portion of the lateral surface of the aircraft and for providing image data relating to the captured image. A receiver is located aboard the aircraft for receiving a signal including the image data relating to the captured image. In addition, a display device also is located aboard the aircraft and in communication with the receiver, the display device for receiving the image data from the receiver and for displaying to a user aboard the aircraft the image data in a human intelligible form. A user interface located aboard the aircraft is provided for receiving from the user an input signal including an indication of a location of the doorway relative to the displayed image data, and for providing data relating to the input signal. A processor is also provided for determining a location of the doorway in dependence upon the data relating to the input signal and the image data, and for providing a control signal relating to the determined location of the doorway.
