The present disclosure provides an aircraft security door as well as methods, systems and apparatus for handling an aircraft security door. In one implementation, a method for installing an aircraft security door onto an aircraft is disclosed. The method includes transferring the aircraft security door to an aircraft service stair, supporting the aircraft security door by a bridge crane coupled to the aircraft service stair, positioning the aircraft service stair in proximity to a fuselage of the aircraft adjacent to an opening in the fuselage, positioning the aircraft security door relative to the opening using the bridge crane, and securing the aircraft security door to the opening.

A method, apparatus, system, and computer program product for monitoring a platform. Images are received by a computer system from a sensor system positioned to monitor movement of human beings relative to the platform. A set of the human beings is identified by the computer system in the images. The movement of the set of the human beings relative to the platform is determined by the computer system using the images. A count of the human beings on the platform is determined by the computer system based on the movement determined for the set of the human beings. A set of actions is performed by the computer system based on the count of the human beings on the platform.

A method is provided that reduces time to dock an electric taxi drive system-driven aircraft parking in a parallel orientation at an airport terminal. Passenger loading bridges are pre-positioned to substantially align with forward and rear doors of the aircraft. Pre-positioned passenger loading bridges extend from the terminal to locations that align with terminal-facing forward and rear doors when electric taxi systems maneuver the aircraft into the parallel parking orientation. The passenger loading bridge connected to a rear door may be pre-positioned at a height above the ramp surface above or below the height of the aircraft's horizontal stabilizer or below the height of the wing to enhance safety and further reduce connection and passenger transfer time. Connection of the pre-positioned passenger loading bridges with the aircraft doors should require only minimal adjustment before passenger transfer between the aircraft and terminal may begin.

Provided is a passenger boarding bridge monitoring device, for passenger boarding bridges each including: a rotunda; a tunnel unit; a travel device; a cab; and detectors that detect a rotational angle of the rotunda and the cab and a length of the tunnel unit. The monitoring device calculates a current position of a virtual line based on detection values of the respective detectors of the one bridge, the virtual line being shifted outward from a profile of the one bridge and conforming to the profile; calculates a current position of a virtual line based on detection values of the respective detectors of the other bridge, the virtual line either extending along or being shifted outward from a profile of the other bridge; and determines whether or not the two virtual lines are in a state of crossing each other, and if so, performs a first coming-close hindering process.

The passenger boarding includes a rotunda, a tunnel portion, a cab and a first detection device configured to detect an angle of the rotunda from the first axis around an origin point, and a second detector configured to measure a distance of the tunnel from the origin point in the extensible/contractable direction, provided at the tunnel.

A coupling module for forming an interface between a cabin of an air passenger bridge and an aircraft. The coupling module has a projecting roof and a floor arrangement spanned by the projecting roof. The end face of the floor arrangement facing the cabin is fastenable to the cabin by at least one releasable fastening means, and the floor arrangement is connectable spaced apart from its end face to the cabin by at least one anchorage means.

A passenger boarding bridge includes: a rotunda rotatable about a vertical axis; a tunnel unit; a cab; a lifting/lowering mechanism; and a travel unit. A control method includes, at a time of docking the cab with an entrance of an aircraft: calculating relative positional information indicating a position of the entrance as seen from the cab when the travel unit is at a movement start position; calculating positional information of a destination position based on the movement start position and the relative positional information in a case where a distance from the movement start position to the destination position is less than a horizontal distance from the vertical axis to a center point of the travel unit; calculating a target travel angle; and controlling the travel unit such that a travel angle of the travel unit is kept to the target travel angle during traveling.
