Aircraft Master Indicator for Checklist Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft instrumentation relies on paper-based checklists that require significant time and effort to analyze multiple systems, necessitating a more efficient method to present checklist information to operators.
Innovation Solution
An aircraft instrumentation system with a master indicator that activates in response to trigger events, allowing user input to display relevant information, including checklists and synoptics, to facilitate quicker response times and reduced effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If paper-based checklists are used to present aircraft system information, then comprehensive information can be provided, but the response time and effort required by pilots increase significantly
Solution Approach 1:
The patent creates an electronic copy of the paper-based checklist system, displaying checklist items and synoptic diagrams on an electronic display unit. This electronic copy provides the same comprehensive information as the paper version while enabling faster access and interaction through electronic interfaces, directly resolving the contradiction between information completeness and response time.
Solution Approach 2:
The patent replaces the mechanical paper-based system with an electronic display and control system. Pilots interact with electronic checklists through display units rather than physically handling paper checklists, enabling faster information retrieval and reducing the time required to respond to system warnings while maintaining comprehensive information delivery.
2Loss of information
If paper-based checklists are used, then all necessary information can be displayed, but the complexity of analyzing multiple components increases pilot effort
Solution Approach 1:
The patent segments the checklist information into distinct displayable items and synoptic diagrams that can be individually selected and viewed on the electronic display. This segmentation allows pilots to access specific system information without having to analyze entire paper checklists, reducing cognitive effort while maintaining comprehensive information availability.
Solution Approach 2:
The electronic display unit acts as an intermediary between the aircraft's multiple components and the pilot. It processes and presents information in an organized, selectable format that reduces the pilot's analytical burden compared to reviewing comprehensive paper checklists, while still providing access to all necessary system information.
3Reliability
If multiple warning and caution lights are used to indicate system status, then comprehensive system monitoring is achieved, but the time to identify and respond to issues increases
Solution Approach 1:
The patent merges the information from multiple warning and caution lights with corresponding synoptic diagrams and checklist items on a single electronic display. This integration allows pilots to see the relationship between multiple system alerts and their corresponding components simultaneously, reducing the time required to identify and respond to issues while maintaining comprehensive system monitoring.

AI summary
A method and an instrumentation system for an aircraft are provided. The method of presenting aircraft information includes activating a master indicator in response to a trigger event associated with operation of the aircraft, receiving a user input associated with the master indicator, and displaying information associated with the trigger event in response to receiving the user input associated with the master indicator. The instrumentation system performs the operations of the method.
