ABSTRACT:
In a method for aligning an aircraft-engaging end of a passenger boarding bridge with a doorway of an aircraft, a first sensor disposed aboard the aircraft is used for sensing first information relating to a current bridge alignment operation and a second sensor disposed at a location that is remote from the aircraft is used for sensing second information relating to the current bridge alignment operation. The sensed first information and the sensed second information are received at a processor. The processor subsequently determines instruction data for moving the aircraft-engaging end of the passenger boarding bridge along a direction toward the doorway of the aircraft, based upon the sensed first information and the sensed second information.
