Aircraft Display Center and Range Retention Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft display systems, such as EFIS, face inefficiencies due to limitations in centering and range control when switching between MAP and PLN display modes, requiring pilots to reselect settings, increasing workload and reducing efficiency.
Innovation Solution
Implementing a center and range retention module that stores and retains desired settings for each display mode, allowing pilots to seamlessly switch between MAP and PLN modes without losing their centering locations and range settings, using inputs from a control panel to manage and display maps efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display defaults to the last range selected on the EFIS control panel when switching between display modes, then the system maintains simplicity in display management, but the pilot must reselect center and range settings when switching between MAP and PLN display modes, increasing pilot workload and reducing efficiency
Solution Approach 1:
The system performs preliminary action by storing the center and range settings for each display mode (MAP and PLN) separately before mode switching occurs. When a pilot switches between display modes, the system automatically retrieves and applies the pre-stored settings for the target mode, eliminating the need for pilots to reselect settings and thereby reducing workload and time loss.
2Stability of the object's composition
If the display centers on ownship position in each display mode, then the display system maintains consistent default behavior, but the pilot cannot retain customized centering locations when switching between MAP and PLN display modes, requiring multiple inputs and reducing efficiency
Solution Approach 1:
The system applies local quality by maintaining different centering settings for different display modes. Instead of a single global centering setting, the system stores separate centering locations for MAP mode and PLN mode, allowing each mode to have its own optimized default centering behavior. This enables pilots to have customized centering locations for each mode while maintaining stability within each mode.
3Ease of operation
If the system stores separate center and range settings for each display mode, then the pilot can retain settings when switching modes, but the device complexity increases with additional storage and management requirements
Solution Approach 1:
The system applies segmentation by dividing the settings management into separate, independent storage areas for each display mode. Instead of a complex unified settings system, the patent creates distinct storage locations for MAP mode settings and PLN mode settings, each managing only their own parameters. This segmentation simplifies the overall system architecture while enabling settings retention across mode switches.

AI summary
Technologies are described herein for providing enhanced center and range control on an aircraft display. According to embodiments, a display mode is selected to display a map on the aircraft display. A range input for displaying the map in the selected display mode at a desired range and a centering input for centering on a predefined map location on the aircraft display are received. The range input and the centering input associated with the selected display mode are then stored. When the selected display mode is deselected and then reselected, the map is displayed on the aircraft display in the selected display mode according to at least one of the stored range input and the centering input associated with the selected display mode.
