VFR Navigation System Dynamic Path Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Visual flight rules (VFR) navigation systems are hindered by cluttered aeronautical navigation charts, making it difficult for pilots to identify and maintain the desired path of approach to a runway, increasing the risk of pilot error due to the complexity of multiple paths and obstructions.
Innovation Solution
A VFR navigation system that dynamically determines and highlights a suggested path of approach using flight plan data, navigation information from sensors and external systems, and aeronautical charts, allowing the pilot to focus on relevant topographical features and obstructions, thereby simplifying navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aeronautical navigation charts include representations of multiple paths of approach and multiple VFR flight routes, then the chart provides comprehensive navigation options, but the chart becomes cluttered and difficult to read
Solution Approach 1:
The patent extracts and removes unnecessary path representations from the navigation display. The system selectively removes representations of paths that are not applicable to current flight conditions (such as IFR paths when flying VFR, or paths inconsistent with current position and destination), leaving only the relevant paths visible. This reduces chart clutter while preserving comprehensive navigation options when needed.
Solution Approach 2:
The patent implements dynamic adjustment of the navigation display based on real-time flight conditions. The system continuously monitors flight parameters (position, destination, weather, flight rules) and dynamically updates which paths are displayed and highlighted. This dynamic behavior allows the chart to adapt between showing comprehensive options and simplified views based on current operational needs.
2Loss of information
If aeronautical navigation charts display all available paths and features, then complete information is provided, but the pilot cannot quickly locate the desired path of approach
Solution Approach 1:
The patent applies local quality by differentiating the visual properties of different paths based on their relevance. The desired path of approach is highlighted with distinct visual characteristics (such as enhanced coloring, thickness, or illumination) to make it stand out from other paths. This allows the pilot to quickly locate the desired path without sacrificing the presence of other available paths on the display.
Solution Approach 2:
The patent utilizes color changes to indicate path relevance and status. Different colors or color intensities are applied to different paths based on factors such as whether the path is currently recommended, whether it matches current flight conditions, or whether it is the optimal approach path. This visual differentiation enables rapid path identification while maintaining complete information display.
3Ease of operation
If the pilot must manually identify the desired path among multiple options, then pilot control is maintained, but the risk of pilot error increases
Solution Approach 1:
The patent implements feedback by continuously monitoring flight conditions and automatically updating the recommended path display. The system provides feedback to the pilot about which path is currently most appropriate based on real-time data (position, weather, destination), reducing the cognitive load and decision-making burden on the pilot. This feedback mechanism maintains pilot control while reducing the risk of error through automated situational awareness.
Data Source
AI summary
A method includes receiving visual flight rules (VFR) data and determining a suggested path of approach for an aircraft based on the VFR data. The suggested path of approach may correspond to a flight path of the aircraft to a runway of an airport. The method includes highlighting a representation of the suggested path of approach at a display device.
