VFR Chart Generation Using Route-Optimized Bounding Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VFR charting solutions based on latitude/longitude grids require pilots to use multiple charts for short flights, as they do not consider popular flight routes, leading to increased flight planning workload and inconvenience.
Innovation Solution
Generating navigational charts with boundaries optimized for popular VFR flight routes, using historical flight plan data to define bounding boxes that align with actual flight paths, allowing for fewer charts to be used and easier flight planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If VFR charts are based on latitude/longitude grids, then chart boundaries are simple and standardized, but pilots must use multiple charts for short flights and flight planning workload increases
Solution Approach 1:
The patent applies local quality by transitioning from uniform latitude/longitude grid boundaries to locally optimized boundaries that align with actual flight routes. Each chart's boundaries are customized based on the specific geographic area and popular flight paths within that area, allowing pilots to remain on a single chart for longer portions of flights. This resolves the contradiction by sacrificing the simplicity of standardized boundaries to reduce flight planning workload and improve operational ease.
2Ease of manufacture
If VFR charts are based on latitude/longitude grids, then chart generation is straightforward, but the number of charts required increases for short flights
Solution Approach 1:
The patent applies parameter changes by fundamentally altering the boundary definition parameters from fixed latitude/longitude values to dynamically determined boundaries based on popular flight routes and historical flight plan data. This allows the chart boundaries to adapt to actual navigation patterns, reducing the quantity of charts required while maintaining ease of chart generation through automated boundary determination algorithms.
3Productivity
If VFR charts use standardized boundaries, then chart production is efficient, but pilots frequently need to switch between charts during flights
Solution Approach 1:
The patent applies preliminary action by pre-determining optimal chart boundaries based on historical flight plan data and popular flight routes before pilots need to use the charts. This preliminary analysis of flight patterns allows chart boundaries to be pre-configured to match actual navigation needs, preventing the need for frequent chart switching during flights and reducing time loss while maintaining efficient automated chart production.

AI summary
A method for generating one or more navigational charts for a geographic area is described. The method includes determining a frequency of travel between a plurality of destinations for the geographic area, the geographic area including a number of travel routes therein, defining one or more bounding boxes for placement within the geographic area, where the placement optimizes the number of travel routes within each bounding box, and generating one or more navigation charts for the area that have boundaries based on the bounding box definitions.
