Dynamic Flight Information Evaluation System for Pilot Cognitive Workload Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information management systems for aircraft pilots overwhelm them with non-relevant landing approach information, increasing cognitive workload due to the need for manual filtering of data based on specific aircraft categories, weather, and airport conditions, as existing digital systems lack real-time interaction and dynamic data filtering capabilities.
Innovation Solution
A dynamic flight information evaluation system that analyzes real-time context-sensitive data to determine and display only the relevant subset of minima information needed for a specific landing approach, using a display system that can highlight pertinent information in different colors to reduce cognitive workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all approach minima information is displayed to the pilot, then complete information is available for all possible conditions, but cognitive workload increases significantly due to the need to filter non-relevant information
Solution Approach 1:
The system extracts and displays only the specific minima information relevant to the current operational conditions (aircraft category, weather, airport facilities) while filtering out non-relevant information. This extraction principle resolves the contradiction by providing complete relevant information without the burden of irrelevant data, directly reducing cognitive workload while maintaining information completeness for the specific situation.
Solution Approach 2:
The system applies local quality by tailoring the displayed information to the specific local conditions of each approach scenario. Different aircraft categories, weather conditions, and airport configurations receive customized information sets, ensuring each pilot gets exactly the information needed for their specific situation rather than a generic comprehensive set, thereby reducing cognitive workload while maintaining local information completeness.
2Adaptability or versatility
If digital EFB devices display all minima information, then all possible operational scenarios are covered, but real-time interaction and dynamic filtering capabilities are lacking
Solution Approach 1:
The system implements dynamics by enabling real-time updating of displayed minima information based on current operational parameters. As weather conditions, aircraft configuration, or airport status changes, the system dynamically filters and updates the displayed information without requiring manual intervention, thus providing adaptability to all operational scenarios while automating the filtering process in real-time.
Solution Approach 2:
The system incorporates feedback mechanisms that continuously monitor operational parameters (weather, aircraft category, airport facilities) and automatically adjust the displayed minima information accordingly. This feedback loop ensures comprehensive coverage of operational scenarios while maintaining automated real-time filtering, resolving the contradiction between adaptability and automation extent.
3Ease of operation
If custom paper charts are made for specific aircraft categories, then information is tailored to the aircraft type, but information pertaining to multiple airport and visibility conditions is still presented
Solution Approach 1:
The system performs preliminary action by pre-filtering minima information based on the specific aircraft category, current weather conditions, and airport facilities before presentation to the pilot. This preliminary filtering eliminates the need for pilots to manually filter information during critical approach phases, maintaining aircraft-specific tailoring while significantly reducing the quantity of information that requires cognitive processing.
Solution Approach 2:
The system implements self-service by automatically filtering and presenting only the relevant minima information based on real-time operational parameters without requiring manual intervention from the pilot. This self-service capability maintains aircraft-category-specific information tailoring while eliminating the burden of filtering multiple airport and visibility conditions, directly reducing the quantity of information the pilot must process.

AI summary
A method and system for dynamically evaluating a quantity of context sensitive information used by an operator of an airborne mobile platform in performing an operational procedure involving said mobile platform, and determining, in real time, a sub-quantity of context sensitive information that pertains to only that sub-quantity of information required by said operator to execute said operational procedure. The sub-quantity of information is then displayed on a display in real time for the operator. The method and system significantly eases the cognitive workload of the operator by enabling the operator to focus on and digest only that sub-quantity of information that is pertinent to performing the operational procedure with the specific type of mobile platform being operated. In one embodiment the sub-quantity of information pertains to minima information for performing an aircraft landing approach operation.
