Abstract:
A system for preventing a rack fault condition of a passenger boarding bridge includes a plurality of electromagnetic sensors that are disposed for sensing separately a rotational movement of each one of a first and a second electromechanical screw jack, one electromechanical screw jack located adjacent to each lateral sidewall surface of the passenger boarding bridge. The system also includes a control circuit in communication with the plurality of electromagnetic sensors. The control circuit receives signals from the sensors, which signals are indicative of the sensed rotational movement of each one of the first and second electromechanical screw jacks. A value is determined relating to a rotational synchronization of the first and second electromechanical screw jacks. When the determined value is outside a predetermined range of threshold values, a control signal is provided for affecting the rotational movement of at least one of the first and second electromechanical screw jacks.
Abstract:
A method for guiding an aircraft toward a stopping position within an aircraft stand of an airport includes receiving a radio frequency (RF) signal from a radio frequency identification (RFID) tag that is carried by the aircraft. The RF signal comprises aircraft-type data that is retrievably stored in an integrated circuit of the RFID tag, the aircraft-type data being indicative of a type of the aircraft. A current location of the aircraft is sensed, and based on the aircraft-type data and the sensed current location of the aircraft, instructions are determined for guiding the aircraft from the current location thereof to a predetermined stopping position for the type of the aircraft. Using a visual docking guidance system (VDGS) associated with the aircraft stand, the instructions are displayed in human-intelligible form for being viewed by a user aboard the aircraft.
Abstract:
A system for guiding an aircraft to a stopping position adjacent to a passenger boarding bridge includes a radio frequency identification (RFID) tag for being disposed at a location that is remote from the aircraft, and that is known relative to the stopping position. The RFID tag has a tag antenna and an integrated circuit for encoding data relating to the RFID tag. The system also includes an antenna for being disposed aboard the aircraft, for emitting radio frequency waves and for receiving from the RFID tag a wireless data communication signal including the encoded data. A processor disposed aboard the aircraft and in communication with the antenna identifies the encoded data within the wireless data communication signal, and determines spatial information relating to a location of the RFID tag relative to the antenna. The processor is also for determining instruction data for guiding the aircraft to the stopping position based on the determined spatial information and the known location of the RFID tag relative to the stopping position.
Abstract:
A system is provided for aligning a first passenger boarding bridge tunnel section with a first doorway of an aircraft and for aligning a second passenger boarding bridge tunnel section with a second doorway of the aircraft includes. The system includes a sensor for sensing an orientation of a first passenger boarding bridge tunnel section when it is in an aligned condition with a first doorway of the aircraft, and for sensing an orientation of a second passenger boarding bridge tunnel section when it is in other than an aligned condition with the second doorway of the aircraft. The sensor is in communication with a controller. The controller is for receiving a signal from the sensor, and for determining the orientation of the first passenger boarding bridge tunnel section and the orientation of the second passenger boarding bridge tunnel section in dependence upon the signal. Based upon the determined orientation information, as well as stored information relating to a location of the second doorway relative to the first doorway, the controller determines a movement for moving the second passenger boarding bridge tunnel section into an aligned condition with the second doorway of the aircraft.
Abstract:
Vertical alignment of a movable bridge with a doorway of an aircraft is achieved by moving a sensor disposed on the movable bridge in a generally downward direction so as to sense a position of an upper surface of the aircraft. The upper surface of the aircraft has a known elevational relationship relative to the doorway of the aircraft, which is used along with the sensed position to align an aircraft engaging portion of the movable bridge with the doorway. The method accommodates different heights of a same model of aircraft resulting from differences in the aircraft loads and is easily implemented using either contact or non-contact sensors.
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.

Abstract:
A system for aligning one end of a passenger loading bridge to an aircraft having a doorway is provided. A transmitter is disposed within a space of a side-wall of an aircraft, the side-wall including an inner wall defining an interior surface of the side-wall and an outer wall defining an exterior surface of the side-wall, the inner wall and the outer wall disposed in a spaced-apart arrangement one relative to the other, so as to define the space therebetween. The transmitter is for providing an electromagnetic signal including a homing signal for use during an operation for aligning the one end of the passenger loading bridge to the doorway of the aircraft. A receiver is disposed about a point having a known location relative to the one end of the passenger loading bridge, for receiving the electromagnetic signal transmitted from the transmitter, and for providing an electrical output signal relating to the electromagnetic signal. A bridge controller is provided in electrical communication with the receiver, for receiving the electrical output signal and for providing a control signal relating thereto.

A kit and method for retrofitting an aircraft is also disclosed.
Abstract:
Apparatus for moving passengers between an airport terminal building and a doorway of an aircraft located rearward of a wing of the aircraft which includes a passageway member pivotally anchored to one of the terminal building and a passenger loading bridge for servicing a front doorway of a same aircraft. The apparatus includes a telescopic passageway member that is pivotally mounted to the passageway member via a flexible connection. In use, the apparatus is cantilevered over the wing of an aircraft with the flexible connection substantially above a highest point along an upper surface of the aircraft wing. The flexible connection allows a cabin carried at an outboard end of the telescopic passageway member to mate to the rear doorway of the aircraft, providing an open passageway between the rear doorway and the terminal building through which passengers deplane. Positioning the flexible connection above the high point of the wing approximately minimizes the inclination of each passageway member floor surface.
Abstract:
Disclosed is a system and method for automatically aligning an end of a passenger boarding bridge with a doorway of an aircraft. A beacon is transmitted from a predetermined location aboard the aircraft, such as within a window proximate a doorway of the aircraft. The beacon is sensed and from the sensed beacon a direction for moving of the end of the passenger boarding bridge is determined. The passenger boarding bridge is then moved according to the determined direction. The process is iterated until the docking of the bridge to the aircraft is completed.
