Aerobridge with Multiple Access Points for Aircraft Turnaround
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft passenger-boarding bridges (PBBs) are inefficient in handling large aircrafts, leading to lengthy boarding and deplaning processes, which increase turnaround times, restrict flight schedules, and result in suboptimal aircraft utilization and revenue generation, due to limitations in accessing multiple doors and accommodating varying aircraft configurations.
Innovation Solution
An extendible aerobridge with a vertically and horizontally adjustable cantilevered structure, featuring multiple passageways and a retractable support system, allowing simultaneous access to multiple doors along the aircraft, including those above and behind the wing roots, with optional methods for mating and detaching, such as the shoot-out and swing methods, to accommodate different parking configurations and aircraft types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single conventional PBB is used to service one door, then the structure is simple and cost-effective, but boarding and deplaning times become excessively long for large aircraft
Solution Approach 1:
The PBB is divided into multiple independent service units (first PBB for forward door, second PBB for aft door), each capable of independently servicing different doors simultaneously. This segmentation allows parallel passenger flow through multiple doors, dramatically increasing boarding and deplaning productivity while reducing overall turnaround time.
Solution Approach 2:
The second PBB is positioned to service the aft door located above the wing root, utilizing the vertical and lateral space above the wing structure. This dimensional positioning enables access to previously unreachable doors without interfering with the first PBB's operation at the forward door, allowing simultaneous multi-door service.
2Productivity
If multiple conventional PBBs are used to service multiple doors, then boarding efficiency improves, but the complexity and cost of the system increases significantly
Solution Approach 1:
Both PBB units are designed with identical multi-functional capabilities to service various door positions on different aircraft types. Each PBB can independently adjust to service forward doors, aft doors, and doors above wing roots, allowing a standardized design to perform multiple functions rather than requiring specialized equipment for each door position.
Solution Approach 2:
The PBB incorporates vertically and horizontally adjustable components that can dynamically reposition the service interface to match different door locations on various aircraft configurations. This dynamic adjustability allows a single PBB design to adapt to multiple door positions, reducing the need for multiple specialized PBBs.
3Area of stationary object
If conventional PBBs are used with nosed-in parking, then terminal space utilization improves, but only forward doors can be accessed, limiting boarding efficiency
Solution Approach 1:
The dual PBB configuration segments the door access function, with the first PBB servicing forward doors and the second PBB specifically positioned to service aft doors above wing roots. This segmentation enables both forward and aft door access while maintaining nosed-in parking, overcoming the limitation of single-door access.
Solution Approach 2:
The second PBB acts as an intermediary structure that reaches over the wing root area to provide access to aft doors that would otherwise be inaccessible during nosed-in parking. This intermediary positioning enables extended door access capability while maintaining the space-efficient nosed-in parking configuration.
4Adaptability or versatility
If the aerobridge extends over the wing root to access aft doors, then access to all doors is enabled, but the risk of bridge collapse increases due to structural stress
Solution Approach 1:
The bridge structure is segmented into two separate PBB units rather than one long continuous bridge. Each unit has its own independent support structure and load-bearing capacity, distributing the structural stress and eliminating the risk of complete bridge failure if one section is compromised.
Solution Approach 2:
The support systems for each PBB are designed with counterbalancing mechanisms and distributed weight support to offset the structural stress of reaching over wing roots. The vertically and horizontally adjustable support components provide counteracting forces to maintain structural integrity under load.

AI summary
An aerobridge and dual method of operation thereof that significantly reduces the turnaround time (time between routes) of an aircraft vehicle at a terminal gate. The aerobridge includes a cab rotunda, cab, and a bridge formed of a plurality of passageways and/or ramps. The passageways/ramps are telescopically received in a proximal-most passageway/ramp in a retracted position and are telescopically extended along the aircraft vehicle in an extended position. The aerobridge may further include a plurality of height-adjustable and/or retractable support mechanisms disposed in underlying relation to the bridge. The aerobridge can be mated with an aircraft vehicle using a shoot-out method or a swing method, thus accommodating different airports' configurations and limitations.
