Abstract:
A method of aligning one end of a passenger boarding bridge with a doorway of an aircraft includes a step of parking the aircraft within a parking space that is defined adjacent to the passenger boarding bridge. An imager disposed aboard the aircraft is used for scanning a target that is located proximate the parking space, the target including machine-readable information that is uniquely associated with the passenger boarding bridge. Data relating to the machine-readable information of the target is extracted from image data and used for encoding a signal for transmission to a controller of the passenger boarding bridge. The controller determines the presence of the extracted data and compares the data to a unique bridge identifier code for that passenger boarding bridge. When a match is determined, then communication with an aircraft within or proximate a parking space adjacent to that passenger boarding bridge is confirmed.
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.
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:
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 bridge controller for performing automated alignment of the aircraft-engaging end of the passenger boarding bridge to the doorway. A user interface is located aboard the aircraft for receiving, from a user aboard the aircraft, an input signal relating to a command for aborting automated alignment of the aircraft-engaging end of the passenger boarding bridge, and for providing data relating to the input signal. A transmitter is also 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 first signal including the data relating to the input signal. Furthermore, a receiver is located at a location that is remote from the aircraft and is in communication with the bridge controller, for receiving the first signal and for providing to the bridge controller an electrical output signal relating to the first signal. During use, the bridge controller aborts an automated alignment process already in progress in dependence upon receiving the electrical output signal.
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 novel apparatus for moving passengers between an airport terminal building and a doorway of an aircraft located rearward of a wing of the aircraft. The inventive apparatus 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:
Disclosure 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 beacon 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:
A failsafe support for use with a height adjustable passenger loading bridge. A main support member supports the weight of a passenger loading bridge passageway under normal operating conditions. The failsafe support includes a self-arresting mechanism for varying a length of a height-adjusting portion of the failsafe support in order to raise and lower a support portion of the failsafe support. The support portion is positionable adjacent to and spaced apart from a lower surface of the passenger loading bridge passageway, for supporting the weight of the passageway in the event of a failure of the main support member. The self-arresting mechanism prevents the passageway of the passenger loading bridge from descending to a level below the support portion.
Abstract:
A system for automatically retracting a passenger loading bridge from an engaged position relative to an aircraft having a door, the aircraft being releasably connectable to a service provider is disclosed. The system comprising at least a sensor for detecting one of a plurality of predetermined events other than a user input at an input device coupled thereto and for providing a signal in dependence upon said detected predetermined events; and a bridge actuator in operative communication with the at least a sensor for receiving the signal and for automatically performing a retraction movement in order to retract the bridge from the aircraft in response to the signal indicative of one of the plurality of predetermined events being sensed.
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.
