Abstract:
Disclosed is a system and method for automatically aligning an end of a passenger loading bridge with a doorway of an aircraft. A beacon is transmitted from the doorway of the aircraft. The location is sensed and from the sensed beacon a direction for moving of the end of the passenger loading bridge is determined. The passenger loading bridge is then moved according to the determined direction. The process is iterated until the docking of the bridge to the aircraft is completed.

Abstract:
Passenger boarding bridges have adjustable walkways that are elevated high above the ground when servicing aircraft doorways. Passenger safety is improved by automatically stabilizing the passenger boarding bridge when it is in an aligned condition. A method for automatically stabilizing the passenger boarding bridge includes moving the aircraft-engaging end of the passenger boarding bridge into an aligned relationship relative to the doorway of an aircraft. The aligned relationship between the aircraft-engaging end of the passenger boarding bridge and the doorway of the aircraft is detected automatically. Adjustable jacks, which are fixedly mounted to the passenger boarding bridge wheel carriage, are actuated between a retracted condition and an extended condition. In the extended condition, the adjustable jacks engage a ground surface below the passenger boarding bridge, thereby increasing the stability of the passenger boarding bridge.
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 a receiver that is located aboard the aircraft for receiving a signal, including image data for being displayed to a user aboard the aircraft. The system further includes a display device located aboard the aircraft and in communication with the receiver, the display device for receiving the image data from the receiver and for displaying the image data in a human intelligible form to the user aboard the aircraft. A user interface is also located aboard the aircraft for receiving an input signal from the user, which is indicative of one of a go command and a no-go command for automatically aligning the passenger boarding bridge, and for providing data relating to the input signal. Additionally, a transmitter is located aboard the aircraft and in communication with the user interface, the transmitter for receiving the data relating to the input signal and for transmitting a second signal including the data relating to the input signal. During use, the image data relates to features along a lateral surface of the aircraft, the lateral surface including the doorway to which the passenger boarding bridge is to be aligned.
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 preconditioned air system for cooling an interior cabin space of a parked aircraft includes a thermal energy storage unit, which contains a thermal energy storage medium for storing cooling capacity. During use, a ground-based air-cooling unit is placed in thermal communication with the thermal energy storage medium. The ground-based air-cooling unit draws upon cooling capacity that has been stored previously within the thermal storage medium for cooling the interior cabin space. Storage of cooling capacity is performed during off-peak demand times and/or during low power cost times. System modularity supports cooling of variously sized aircraft even under extreme temperature conditions.
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:
Disclosed is a method and system for aligning a door of an aircraft to a passenger loading bridge. A final parking position of the aircraft is defined as being immediately adjacent to a position of the passenger loading bridge, such that when the aircraft is stopped at the final parking position, the passenger loading bridge requires only a telescopic extension of less than about 1 meter to complete the alignment operation. To this end, an indicating device that works cooperatively with an aircraft-engaging end of the passenger loading bridge is provided for displaying human intelligible instructions for use by a pilot of the aircraft to guide the aircraft to the final parking position.
Abstract:
Disclosed is an apparatus for moving passengers between an airport terminal building and a doorway of an aircraft located rearward of a wing of the aircraft. The apparatus includes a first passageway member pivotally coupled at an inboard end thereof to a rotunda and supported close to an outboard end thereof by a ground support member. The apparatus also includes a telescopic passageway member that is pivotally mounted to the passageway member via a flexible connection disposed therebetween. The telescopic passageway member is for being supported in a cantilever-like fashion such that the telescopic passageway member is extensible over the wing of the aircraft, for servicing the doorway located rearward of the wing. An adjustable support mechanism is mounted at a first end thereof to a surface of the first passageway member and mounted at a second opposite end thereof to a surface of the telescopic passageway member, for vertically swinging the telescopic passageway member relative to the first passageway member in a controllable manner. To this end, an actuator is coupled to the adjustable support mechanism, for driving the adjustable support mechanism so as to vertically swing the telescopic passageway member relative to the first passageway member in the controllable manner, under the control of an electrical controller.
