Automatic Aircraft Navigation Screen Adjustment for Alert Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft pilots face delays and increased workload during stressful alert situations due to the need for manual adjustments of navigation screen display modes and scales to effectively monitor dangerous events, which can divert attention from critical environmental information.
Innovation Solution
An automatic method and device that monitor the aircraft's environment, analyze the navigation screen, and adjust the display mode and scale to present critical information effectively, reducing the pilot's workload by automatically reconfiguring the screen to prioritize essential data and deactivating non-essential information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of display mode and scale is performed, then the pilot can obtain the appropriate image for managing the current situation, but the pilot loses time and experiences increased workload
Solution Approach 1:
The system performs self-adjustment by automatically detecting the alert type and selecting the appropriate display mode and scale without requiring pilot intervention. The navigation display system monitors its own state and environment to autonomously reconfigure the display, eliminating the need for manual pilot operations.
Solution Approach 2:
The system pre-configures multiple display modes and scales before alerts occur. When an alert is detected, the system immediately switches to the pre-prepared appropriate display configuration, eliminating the need for real-time manual adjustment and reducing the time loss during critical situations.
2Ease of operation
If manual adjustment of display mode and scale is performed, then the pilot can obtain the appropriate image for managing the current situation, but the pilot's workload increases
Solution Approach 1:
The system performs self-adjustment by automatically detecting the alert type and selecting the appropriate display mode and scale without requiring pilot intervention. The navigation display system monitors its own state and environment to autonomously reconfigure the display, eliminating the need for manual pilot operations.
Solution Approach 2:
The system continuously monitors the flight environment and alert status, providing feedback to automatically adjust the display configuration. This closed-loop system responds to changing conditions by autonomously selecting the most appropriate display mode, ensuring the pilot always has the optimal information presentation without manual intervention.
3Loss of information
If all information is displayed on the navigation screen, then the pilot has complete information, but the pilot finds it difficult to read and process critical information quickly
Solution Approach 1:
The system extracts and separates critical alert information from the general navigation display. When an alert is detected, the system highlights or isolates the relevant information on the navigation screen, making it stand out from other information. This extraction approach ensures critical information remains visible and accessible while reducing the cognitive load on the pilot.
Solution Approach 2:
The system applies different display characteristics to different parts of the navigation screen based on importance. Critical alert information is highlighted with enhanced visibility, while less critical information is dimmed or obscured. This local differentiation allows the pilot to quickly identify and process critical information without losing context about the overall situation.

AI summary
A method and device are provided for automatically adjusting an image of an aircraft navigation screen. The device includes a determining unit for automatically determining, if necessary, a new display configuration making it possible to present on a navigation screen a detected dangerous event, and a display unit for automatically effecting a change of display of the navigation screen by applying this new display configuration.
