Avionic Display System for Message Superposition and Format Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of avionic systems in aircraft cockpits requires pilots to manually process numerous messages, leading to cumbersome interventions and increased workload, as current display systems are limited and require manual data entry for message processing.
Innovation Solution
A display system that configures avionic data display using a set of predetermined formats, allowing messages to be superimposed on existing displays, with acquisition and display modules managing interaction commands to switch between formats and return to previous displays, simplifying message processing and reducing pilot workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If messages are displayed in a conventional limited interface, then the display system remains simple, but the crew workload increases due to manual data entry and processing
Solution Approach 1:
The display system is segmented into multiple functional modules: a display module that shows messages in a conventional interface, a processing module that automatically handles message data, and an acquisition module that captures crew commands. This segmentation allows the system to maintain a simple display interface while incorporating automated processing capabilities, thereby reducing crew workload without significantly increasing perceived system complexity.
Solution Approach 2:
The processing module automatically processes messages by extracting data and inserting it into the flight management computer without requiring manual crew intervention. The system serves itself by performing data entry and message processing tasks autonomously, which reduces the crew's workload while the overall system complexity remains managed through modular design.
2Adaptability or versatility
If multiple display formats are provided for message processing, then message handling capability improves, but the interface complexity increases
Solution Approach 1:
The display module is designed to present messages in multiple display formats (such as different layouts, detail levels, or organizational structures) while maintaining a consistent and familiar interface paradigm. This multi-functionality allows the system to adapt to different message processing needs without introducing complex or unfamiliar interface elements, thereby enhancing versatility while keeping the interface relatively simple.
Solution Approach 2:
The display format is made dynamic and adjustable based on crew commands acquired by the acquisition module. The system can switch between different display formats on demand, allowing the interface to adapt to the current operational context without requiring the crew to learn multiple static interfaces. This dynamic adaptability provides versatility while maintaining interface simplicity through consistent interaction patterns.
3Productivity
If automatic message processing is implemented, then crew workload decreases, but system complexity increases
Solution Approach 1:
The processing module automatically processes messages by extracting relevant data, formatting it appropriately, and inserting it into the flight management computer without requiring manual crew intervention. This self-service capability significantly improves message processing efficiency and reduces crew workload. The increase in system complexity is mitigated by implementing this automation as a modular, well-defined processing component that operates independently with clear interfaces.
Solution Approach 2:
The acquisition module monitors and acquires crew commands related to message processing and provides feedback to the processing module to adjust its operations accordingly. This feedback mechanism allows the automatic processing system to adapt to crew preferences and operational context, improving productivity while managing system complexity through responsive, adaptive control rather than rigid complex architecture.
