Abstract:
A method for guiding an aircraft toward a stopping position within an aircraft stand of an airport comprises using a visual docking guidance system (VDGS) associated with the aircraft stand for displaying first instructions for guiding the aircraft toward the stopping position. The first instructions are based on an initial determination of the aircraft-type and on first sensed positional information of the aircraft. Aircraft-type data that is stored in a radio frequency identification (RFID) tag carried by the aircraft is then read. Using the VDGS, second instructions are displayed for guiding the aircraft toward the stopping position based on the aircraft-type data and based on second sensed positional information of the aircraft.
Abstract:
A system for aligning an aircraft-engaging end of a passenger boarding bridge with a doorway of an aircraft includes a passive radio frequency identification (RFID) tag for being disposed at a known location aboard the aircraft, relative to the doorway thereof. The passive RFID tag includes a tag antenna and an integrated circuit for encoding data relating to the passive RFID tag. An antenna including a plurality of antenna elements is disposed proximate the aircraft-engaging end of the passenger boarding bridge. The antenna emits radio frequency waves and receives from the passive RFID tag a wireless data communication signal including the encoded data. A processor is provided for identifying the encoded data within the wireless data communication signal, for determining an angle of arrival of the encoded data based on differences in signal received at each of the plurality of antenna elements and for determining an intensity of the signal including the encoded data. A bridge controller in communication with the processor determines a movement of the passenger boarding bridge toward the doorway of the aircraft, based on the determined angle of arrival of the encoded data and the intensity of the signal including the encoded data.
Abstract:
A vision system for use with an automated control system of a passenger boarding bridge includes an inclinometer for determining tilt data relating to deviation of the aircraft-engaging end of the passenger boarding bridge relative a horizontal reference plane. The system also includes an imager disposed near the aircraft-engaging end of the passenger boarding bridge, for capturing image data relating to a portion of the aircraft proximate an expected stopping location of the doorway. A memory element having template image data stored retrievably therein is also provided. The template image data relates to at least a template image including a feature that is indicative of the location of the doorway of the aircraft. The vision system further includes an image data processor for determining alignment data for use in aligning the aircraft-engaging end of the passenger boarding bridge with the doorway of the aircraft. The alignment data being determined based upon the tilt data, the image data, and the template image data.
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. Human intelligible information visually displayed proximate the parking space is determined, the human-intelligible information being uniquely associated with the passenger boarding bridge. Using an input device that is disposed aboard the aircraft, the human-intelligible information is provided to a communication module that is also disposed aboard the aircraft. A signal including the human-intelligible information is transmitted from the communication module to a receiver that is in communication with the passenger boarding bridge. Only signals determined to include the human-intelligible information are accepted as valid signals during a current bridge alignment operation.
Abstract:
A method for parking an aircraft at an expected stopping position at an airport includes a step of receiving an electromagnetic call signal that is transmitted from the aircraft. The electromagnetic call signal includes data that is retrieved from a memory circuit disposed aboard the aircraft, and relates to the type of the aircraft. In addition, positional and trajectory information relating to the aircraft is sensed. Based on the data relating to the type of the aircraft and the sensed positional and trajectory information relating to the aircraft, instructions are determined for guiding the aircraft to an expected stopping position for the specific type of the aircraft. The determined instructions are provided to a pilot of the aircraft, for use in parking the aircraft at the expected stopping position.
Abstract:
A sensor is disposed aboard an aircraft for sensing movement of a passenger boarding bridge during an automated alignment operation. Determinations are made whether the actual sensed movements of the passenger boarding bridge correspond to expected movements of the passenger boarding bridge for a current alignment operation. If the sensed movements do not correspond to the expected movements, then a transmitter aboard the aircraft is used to transmit an anti-collision signal to an automated controller of the passenger boarding bridge.
Abstract:
A method of aligning a passenger boarding bridge to a doorway of an aircraft comprises initiating an automated alignment process for aligning the aircraft-engaging end of the passenger boarding bridge to the doorway. An input signal is received from a user aboard the aircraft, which is indicative of an emergency stop request. A control signal relating to the input signal is transmitted using a transmitter that is disposed aboard the aircraft. The control signal is received at a location that is remote from the aircraft, and the control signal subsequently is provided to a bridge controller of the passenger boarding bridge. The automated alignment process currently in progress is stopped in response to receiving the control signal at the bridge controller.
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.

A cargo conveyor for use in loading and unloading a cargo compartment comprises: a plurality of conveyor units for being disposed within the cargo compartment and for being temporarily arranged to support a loading or unloading conveyor path having a length that varies during a same loading or unloading operation, the conveyor path for being lengthened during the unloading operation and for being shortened during the loading operation, the plurality of conveyor units for being coupled with and decoupled from the conveyor path for lengthening the conveyor path during the unloading operation and for shortening the conveyor path during the loading operation, respectively.
Abstract:
An apparatus is provided for aligning one end of a passenger loading bridge to an aircraft. The apparatus includes a mounting structure and a transceiver including a transmitter portion. The transceiver is for being fixedly mounted, via the mounting structure, at a location within a space that is contained within a side-wall of the aircraft between an interior wall defining an interior surface of the side-wall and an outer wall defining an exterior surface of the side-wall. The transceiver is for wirelessly providing a signal within a predetermined region of the electromagnetic spectrum, the signal comprising information relating to a location of a doorway relative to a location of the transceiver.
