Aircraft Data Display with Automatic Redundant Sensor Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft data display systems require pilots to manually select sensors, increasing workload and risking erroneous data presentation, as they need to compare and choose between multiple sources of information.
Innovation Solution
An automatic display controller system that selects a reliable sensor from a redundant set based on stored logic, using algorithms like median or average calculation to ensure accurate data presentation without pilot intervention, optimizing sensor usage and maintaining system integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pilots manually select sensors to display information, then they can choose between multiple sensor sources, but this increases pilot workload and risks erroneous data presentation
Solution Approach 1:
The system performs automatic sensor selection and data validation without requiring pilot intervention. The display controller automatically compares sensor readings, identifies reliable sensors, and presents validated information, allowing the system to serve itself rather than requiring manual pilot operation for sensor selection
Solution Approach 2:
The system performs preliminary validation and comparison of sensor data before presentation to the pilot. By pre-comparing readings from multiple sensors and identifying reliable sources in advance, the system eliminates the need for pilots to perform manual comparison and selection during flight operations
2Reliability
If pilots manually compare and choose between sensor sources, then they can select reliable data, but this increases the risk of erroneous data presentation due to human error
Solution Approach 1:
The system implements automatic feedback loops where sensor readings are continuously compared against expected ranges and other sensor data. The display controller receives feedback from multiple sensors, validates consistency, and automatically adjusts or flags unreliable readings, creating a self-correcting system that eliminates human error in data validation
Solution Approach 2:
The display controller acts as an intermediary between sensors and the pilot interface. It mediates the data flow by automatically comparing sensor readings, identifying discrepancies, and presenting only validated information, thereby removing the pilot from the direct comparison task and eliminating human error in this critical function
3Reliability
If multiple redundant sensors are used, then system reliability is improved, but device complexity increases due to manual selection requirements
Solution Approach 1:
The system merges the functions of multiple sensors through automatic comparison and validation logic in the display controller. By combining readings from multiple redundant sensors and processing them through unified validation algorithms, the system maintains reliability while reducing the operational complexity of managing individual sensor sources
Solution Approach 2:
The system changes the operational parameters of redundant sensors from independent manual selection to integrated automatic comparison. By transforming the management approach from discrete sensor selection to continuous parameter validation and averaging, the system maintains redundancy benefits while simplifying the operational interface
