Aviation Chart Display System for Pilot Cognitive Workload Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft pilots face difficulties in quickly locating relevant information from the vast amount of data presented in terminal charts, which can be cluttered with irrelevant information, increasing cognitive workload and reducing readability.
Innovation Solution
A processor-based system that accepts user preferences to emphasize and de-emphasize data in aviation charts using differentiated colors, allowing pilots to customize the display of terminal charts by highlighting pertinent information and de-emphasizing non-relevant data, thereby improving visual organization and readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminal charts contain comprehensive flight procedure data for all aircraft categories and approaches, then the chart provides complete information for various flight procedures, but the chart becomes cluttered and difficult to read
Solution Approach 1:
The patent applies local quality by allowing different portions of the chart to have different visual characteristics. Specifically, it enables selective emphasis of certain data elements (such as minimums, missed approach procedures, or specific approach types) while de-emphasizing or obscuring other elements. This creates localized visual differentiation that helps pilots quickly identify relevant information without losing access to complete data, thereby resolving the contradiction between comprehensive information provision and chart readability.
2Adaptability or versatility
If terminal charts include all applicable data for various flight procedures, then the chart is comprehensive, but pilots spend more time sifting through irrelevant information
Solution Approach 1:
The patent utilizes color changes to differentiate and emphasize specific types of information on the terminal chart. By assigning distinct colors to different data elements (such as highlighting minimums in one color, missed approach procedures in another, or current approach procedures in a third color), the system enables pilots to rapidly scan and identify relevant information based on color coding. This visual differentiation dramatically reduces the time required to locate needed information while maintaining chart comprehensiveness.
Solution Approach 2:
The patent segments the terminal chart into distinct visual zones or sections based on the type of information presented. By dividing the chart into segments that can be independently emphasized or de-emphasized, the system allows pilots to focus their attention on specific segments relevant to their current flight procedure while maintaining awareness of other segments. This segmentation strategy reduces the time to locate information by creating visual anchors that guide the pilot's eyes to critical data elements.
3Adaptability or versatility
If terminal charts present detailed tabular data for all approaches and aircraft categories, then the chart contains complete flight procedure information, but the cognitive workload on pilots increases
Solution Approach 1:
The patent reduces cognitive workload by applying local quality differentiations that highlight critical information and allow pilots to process the chart more efficiently. By making specific data elements visually distinct through emphasis techniques while maintaining the complete data structure, the system enables pilots to quickly identify and process only the most relevant information without becoming overwhelmed by the entirety of the comprehensive data, thus reducing cognitive complexity.
