Distributive Flight Deck Display for Terminal Procedure Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic terminal procedure systems for aircraft increase flight crew workload as they require searching, scrolling, and zooming, which does not significantly reduce the time and labor involved in accessing terminal procedure data compared to paper-based systems.
Innovation Solution
A distributive flight deck display system that includes processors and display devices, which receive and render terminal procedure data, allowing for the selective display of relevant information on primary and multi-function displays, reducing the need for flight crews to act as data routers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If electronic terminal procedure systems are used to eliminate paper versions, then paper storage space is reduced, but flight crew workload increases due to searching, scrolling, and zooming operations
Solution Approach 1:
The terminal procedure chart is segmented into multiple selectable portions (e.g., arrival procedures, departure procedures, approach procedures, airport diagrams) that can be independently displayed on different flight deck display devices. This allows the flight crew to access specific procedure sections directly without searching through entire charts or performing scroll/zoom operations on a single electronic display.
2Loss of information
If electronic terminal procedure displays show complete procedure images, then information completeness is maintained, but display device complexity and operation difficulty increase due to scrolling and zooming requirements
Solution Approach 1:
The system transitions from a single-display electronic interface requiring 2D scrolling and zooming to a multi-dimensional distributed display architecture where different procedure portions are simultaneously presented across multiple flight deck display devices. This spatial distribution eliminates the need for scroll/zoom operations while maintaining complete procedure information availability.
3Measurement precision
If flight crews manually search and extract procedure data from electronic charts, then data accuracy is maintained, but time consumption increases compared to automated distribution
Solution Approach 1:
The flight deck display system automatically receives and distributes terminal procedure data to appropriate display devices without requiring flight crew intervention for data extraction. The system self-services by automatically rendering relevant procedure portions on the correct displays, eliminating the manual search and extract process while maintaining data accuracy through automated data distribution.

AI summary
A display system and method for an aircraft selectively distributes and displays terminal procedure data. The system includes a processor and a display device. The processor is adapted to receive terminal procedure data representative of an airport terminal procedure that is normally illustrated on a terminal procedure chart and is operable, upon receipt of the terminal procedure data, to supply terminal procedure image rendering display commands. Each of the plurality of flight deck display devices is coupled to receive selected ones of the terminal procedure image rendering display commands and is operable, in response thereto, to render a terminal procedure image representative of a portion of the airport terminal procedure that is normally illustrated on the terminal procedure chart.
