Unified Windshear Alert System for Aircraft Piloting Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current piloting assistance systems for aircraft require complex procedures from pilots when multiple alerts for windshear detection are triggered, as they need to manage separate alerts from meteorological radar and enhanced ground proximity warning systems, leading to increased pilot workload and potential safety risks during windshear encounters.
Innovation Solution
A unified piloting assistance system that automatically selects and switches between guidance modes based on alerts from multiple detection assemblies, providing unified alert information and guidance instructions to simplify pilot operations, allowing for seamless adaptation through a single shared alert and guidance mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate detection assemblies (meteorological radar and EGPWS) are used to detect windshear, then detection coverage and reliability are improved, but the complexity of alert management and pilot workload increase
Solution Approach 1:
The patent merges multiple separate detection assemblies (meteorological radar and EGPWS) into a unified detection system that processes windshear alerts through a common logic unit. This consolidation maintains the reliability benefits of multiple sensors while eliminating the complexity of managing separate alert systems, as the unified system presents a single integrated alert to the pilot.
Solution Approach 2:
The patent creates a universal alert management system that handles both meteorological radar alerts and EGPWS alerts through a single common logic unit and unified presentation interface. This multi-functional approach allows the system to process different types of windshear detections using the same processing and display mechanisms, reducing pilot workload while maintaining comprehensive detection coverage.
2Reliability
If multiple separate alerts are generated for approaching and entering windshear zones, then comprehensive warning coverage is improved, but pilot response complexity and workload increase
Solution Approach 1:
The patent combines multiple separate windshear alerts (approach alert from radar and enter alert from EGPWS) into a single unified alert presentation. The common logic unit processes both alert types and presents them through a unified interface, maintaining comprehensive warning coverage while simplifying pilot response to a single clear indication rather than multiple separate alerts.
Solution Approach 2:
The patent introduces a common logic unit as an intermediary between the multiple detection assemblies and the pilot interface. This mediator processes alerts from both meteorological radar and EGPWS, applies unified logic to determine appropriate responses, and presents a single simplified alert to the pilot, thereby maintaining comprehensive warning coverage while easing pilot response burden.
3Adaptability or versatility
If manual selection of guidance modes is required when windshear alerts are triggered, then pilot control and adaptability are improved, but response time and productivity are reduced
Solution Approach 1:
The patent implements a self-service guidance system where the common logic unit automatically determines and applies the appropriate guidance mode based on the type of windshear alert detected. The system serves itself by autonomously selecting between different guidance modes (such as go-around or climb) without requiring manual pilot input, thereby maintaining adaptability to different windshear scenarios while significantly reducing response time.
Solution Approach 2:
The patent employs feedback mechanisms where the common logic unit continuously monitors alert conditions from both detection assemblies and automatically adjusts the guidance mode in response. This closed-loop system provides real-time feedback between detection and guidance, enabling automatic adaptation to changing windshear conditions and eliminating the delay associated with manual mode selection by the pilot.

AI summary
A piloting assistance system of a platform, and associated method are provided. The system includes a first detector for detecting a windshear able to generate a first alert that the platform is approaching a windshear zone; a second detector for detecting a windshear able to generate a second alert indicating the presence of the platform in the windshear zone; and a guider of the platform. The guider is able to automatically select a first guidance mode when a first alert is generated by the first detector, and to automatically select at least one second guidance mode different from the first guidance mode when a second alert is generated by the second detector. The system includes an information device able to display unified windshear alert information and/or unified information for implementation of a guidance mode, shared by the first alert and the second alert.
