Navigation Chart Information System Reducing Pilot Visual Burden
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Instrument approach procedure (IAP) charts are visually burdensome due to their dense and redundant information, requiring significant pilot eye movement and containing information in a compact, difficult-to-read format, which can lead to visual strain and inefficiency in navigation.
Innovation Solution
A system and method for generating and presenting navigation chart information that omits redundant data and reorganizes sections in a pilot-friendly format, integrating IAP chart information with flight management system (FMS) data on a single page, using tabs and a graphical user interface to reduce eye movement and improve readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If IAP chart information is presented in a standardized format with all sections included, then completeness of navigation information is improved, but visual burden and pilot eye movement increase
Solution Approach 1:
The patent divides the IAP chart information into multiple selectable tabs (e.g., approach information, missed approach, alternate airport, notams) rather than presenting all information on a single page. This segmentation allows pilots to view only the relevant information for their current needs, reducing visual burden while maintaining information completeness through on-demand access to different sections.
Solution Approach 2:
The patent transitions from a two-dimensional static chart layout to a multi-dimensional interactive interface with tabs and hierarchical organization. This allows information to be organized in multiple layers, where pilots can navigate through different levels of detail and focus on specific sections without being overwhelmed by the entire chart at once.
2Area of stationary object
If IAP chart information is condensed to reduce page size, then display space efficiency is improved, but readability and comprehension difficulty increase
Solution Approach 1:
The patent implements a dynamic display system where the information density and layout can be adjusted based on pilot interaction. The interface allows pilots to expand or collapse sections, adjust font sizes, and control the level of detail displayed, transforming the static condensed chart into a dynamic presentation that adapts to readability needs while maintaining space efficiency.
Solution Approach 2:
The patent applies different levels of information density to different sections of the interface. Critical safety information is presented with higher prominence and larger formatting, while less critical details can be condensed or hidden. This local differentiation of quality ensures that important information remains readable and comprehensible while maintaining overall display space efficiency.
3Loss of information
If redundant information is included in the navigation chart, then information completeness is improved, but information processing time and cognitive load increase
Solution Approach 1:
The patent extracts and separates redundant or less critical information from the main navigation display. Information such as detailed notams, alternate airport data, and missed approach procedures are placed in separate tabs or collapsible sections, allowing pilots to access this information only when needed. This extraction reduces the cognitive load on the primary display while maintaining information completeness through organized accessibility.
4Productivity
If IAP chart information is integrated with FMS information on the same display, then verification efficiency is improved, but display complexity increases
Solution Approach 1:
The patent merges IAP chart information with FMS (Flight Management System) information in a unified display interface. This integration allows pilots to verify that the FMS is properly programmed by directly comparing chart data with FMS data on the same screen, eliminating the need to switch between separate displays or documents. The merging is achieved through coordinated tabs and synchronized data presentation that reduce overall system complexity despite the increased information density.
Data Source
AI summary
A system, device, and method for generating and presenting navigation chart information are disclosed. The navigation chart information presenting system may include a display system comprised of one or more display units receiving image data set representative of an image of navigation chart information from an image generator (IG). The IG may be configured to acquire navigation chart data and generate the image data set as a function of the navigation chart data. The navigation chart data could be representative of a plurality of sections shown in a first visual format of a navigation chart, where each section of the plurality of sections is comprised of a plurality of feature names and feature information associated with one of the plurality of feature names. The image data set could be representative of a plurality of page images comprised of at least a portion of the navigation chart information.
