Predictive Windshear Radar Transmission Status Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current windshear detection systems in aircraft do not provide a clear indication of their transmission status to pilots and ground crew, making it difficult to determine if the system is operating correctly, especially when no hazards are detected, which can lead to safety issues during takeoffs and landings.
Innovation Solution
A method and system that determine if the predictive windshear radar system is transmitting and provide an indication of this status to user interface devices, such as displays, audio devices, or lamps, allowing pilots and ground crew to monitor the system's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the predictive windshear radar system operates automatically without transmission status indication, then the system complexity is reduced and ease of operation is improved, but the reliability of system monitoring deteriorates and loss of information occurs
Solution Approach 1:
The patent implements a feedback mechanism by providing transmission status indications to the cockpit display system. The processing electronics monitor the radar transmission state and provide visual or audible feedback to the pilot through the existing display system, allowing the pilot to confirm system operation without adding complex manual monitoring procedures
Solution Approach 2:
The system performs self-monitoring of its transmission status and automatically provides this information to the pilot through the existing display architecture. The processing electronics independently track whether the radar is transmitting and present this status without requiring additional pilot input or complex external monitoring systems
2Reliability
If transmission status indication is added to the windshear detection system, then the reliability of system monitoring is improved and loss of information is reduced, but the device complexity increases
Solution Approach 1:
The patent utilizes the existing cockpit display system and audio alert system for multiple purposes - both for weather radar display functions and for transmitting windshear system status information. The processing electronics integrate transmission status monitoring with the existing display architecture, allowing one system to serve multiple functions without requiring separate dedicated displays or indicators
Solution Approach 2:
The processing electronics act as an intermediary component that monitors the radar transmission state and translates this information into display-ready signals for the cockpit display system. This intermediary layer integrates the transmission status indication function with the existing display architecture without requiring major system modifications
3Ease of operation
If the system provides only hazard warnings without transmission status, then the ease of operation is maintained, but the loss of information about system operation increases
Solution Approach 1:
The patent segments the information display by providing distinct transmission status indications separate from hazard warning functions. The system displays transmission status as a separate informational element (such as a dedicated indicator or display message) while maintaining separate hazard warning alerts, allowing pilots to distinguish between system operational status and actual weather hazards
Data Source
AI summary
A system and method for indicating a predictive windshear transmission status is provided. The method includes determining if the predictive windshear radar system is transmitting. The method also includes providing an indication of the determination to a user interface device. Additional parameters, such as the operational state of the aircraft, may be used to further define when the indication is provided.
