Aircraft Ground Risk Zone Detection for Invisible Hazard Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively identify and locate risk zones around aircraft during ground phases, particularly due to invisible hazards like kerosene vapors or hydrogen gas, making it difficult for personnel to determine appropriate qualifications and equipment needed for safe operation.
Innovation Solution
A risk zone determination system using electronic circuitry to obtain initial information and operational context, determine and locate risk zones, and transmit their presence to personnel through visual and audible markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If personnel rely on direct visibility to detect hazards, then equipment complexity is reduced, but measurement precision of hazardous areas deteriorates
Solution Approach 1:
The patent introduces an intermediary system consisting of sensors, processors, and display devices that mediate between the hazardous environment and personnel. Sensors detect invisible hazards (kerosene vapors, hydrogen gas), the processor analyzes the data to determine risk zone locations and sizes, and display devices present this information to personnel, enabling accurate detection without direct personnel exposure to hazards
Solution Approach 2:
The patent replaces mechanical/physical direct detection methods with electronic and optical systems. Instead of personnel visually inspecting areas for hazards, electronic sensors detect chemical compositions of gases, optical systems visualize risk zones, and digital processing systems calculate and communicate hazard boundaries, substituting electronic fields for mechanical human sensory detection
2Reliability
If personnel enter at-risk areas without proper qualifications and equipment, then ease of operation improves, but safety deteriorates
Solution Approach 1:
The system performs preliminary identification and marking of risk zones before personnel enter work areas. By pre-determining the location and boundaries of hazardous areas and displaying this information to personnel, the system enables advance preparation of appropriate qualifications and equipment, preventing unsafe entry rather than relying on last-minute decisions
Solution Approach 2:
The system provides continuous feedback to personnel about the location and extent of risk zones through display devices. This feedback loop allows personnel to adjust their behavior, equipment selection, and movement based on real-time or near-real-time information about hazardous areas, enabling informed decision-making about safety and accessibility

AI summary
This disclosure relates to a method for determining at least one risk area within an area around an aircraft during the execution of ground operations around and/or on the aircraft. This method includes, upon receipt of a request to determine at least one risk area: obtaining (402) initial information representative of at least one source of at least one risk, as well as operational context information representative of the aircraft's operational context during such ground operations; determining (403) such risk area and a location thereof; and then transmitting (404) such location to indicate the presence of such at least one risk area at such determined location to personnel operating on and/or around the aircraft during such ground operations.It is possible to identify one or more risk areas and locate them in an area around the aircraft for one or more risks associated with various hazards that may be encountered during ground operations.
