Avionic Display Overlaying Weather Areas on Terrain Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current avionic displays face challenges in efficiently and effectively conveying multiple sets of information, such as terrain and weather data, on a single screen due to similar color palettes leading to confusion, especially in critical situations where separate displays or toggling between screens can be detrimental.
Innovation Solution
A display screen design that overlays adjustable, patterned weather areas with visibly distinct borders over terrain region alerts and area location fills, allowing for adjustable visibility to prioritize critical information, even when using the same color palettes for different data sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If terrain and weather information are displayed using similar color palettes on the same screen, then the display is more compact and information is more integrated, but confusion arises between different information sets
Solution Approach 1:
The display screen is segmented into multiple layers, with terrain information forming a background layer and weather information forming a foreground layer. This layered segmentation allows both information types to occupy the same screen space while maintaining clear visual distinction through depth perception and selective visibility controls.
Solution Approach 2:
Different visual properties are applied to different regions and layers of the display. Terrain and weather information use distinct color palettes, transparency levels, and visual textures in their respective layers, allowing simultaneous display while maintaining information differentiation through localized visual characteristics.
2Loss of information
If separate displays are used for terrain and weather information, then information differentiation is maintained, but pilot workload increases due to mental integration requirements
Solution Approach 1:
Terrain and weather information displays are merged into a single integrated display screen with multiple layers. The system combines what were previously separate displays into one unified interface, allowing pilots to view both information types simultaneously without mental integration across multiple screens, thereby reducing workload while maintaining differentiation through layering.
3Loss of information
If terrain and weather information are toggled between separate screens, then information differentiation is maintained, but critical information delivery is delayed
Solution Approach 1:
Both terrain and weather information are prepared and displayed simultaneously in separate layers before any switching or selection is needed. This preliminary preparation of all information layers allows immediate access to critical information without the time delay of toggling between screens, as all data is already rendered and available in the integrated display.
4Area of stationary object
If multiple information sets are displayed simultaneously using the same color palettes, then screen space is optimized, but visual distinction between information types deteriorates
Solution Approach 1:
The display transitions from two-dimensional color differentiation to three-dimensional layering, adding a depth dimension to the display. By stacking terrain and weather information in separate layers with different transparency and visibility properties, the system optimizes screen space while maintaining visual distinction through spatial separation rather than relying solely on color differentiation.

AI summary
A display screen for displaying multiple sets of information is provided. The display screen includes at least one region of a select color designated to convey a first set of information and a plurality of adjustable areas designated to convey a second set of information. The plurality of adjustable areas overlay at least a portion of the at least one region of select color of the first set of information. Moreover, each adjustable area is defined by an outline and a color encased in the outline.
