Aircraft Display Shifting Runway Lighting Symbology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft display systems are not effective in providing clear and unobstructed visual information about runway approach lighting during landing operations, especially in low visibility conditions, as primary flight symbology often obscures the runway lighting signature.
Innovation Solution
An aircraft display system that includes a processing unit to determine runway lighting information and generate display commands, allowing the display device to render runway lighting symbology in a shifted location relative to the selected runway, preventing interference with primary flight symbology and enhancing visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If runway lighting information is displayed at its actual location on the display device, then the display provides accurate spatial representation of the runway environment, but the primary flight symbology obscures the runway lighting signature making it difficult to identify
Solution Approach 1:
The patent applies dimensional change by shifting the runway lighting symbology from its actual spatial location (first location) to a different location (second location) on the display device. This relocation places the lighting information in a dimension or area of the display that does not overlap with primary flight symbology, thereby eliminating obscuration while maintaining accurate spatial representation through the shifted display position
2Device complexity
If conventional display systems show all flight information in a single display area, then the system maintains simple display architecture, but the runway lighting information becomes obscured and harder to identify during landing operations
Solution Approach 1:
The patent segments the display area into different functional zones by relocating runway lighting symbology to a specific second location that is separate from the area occupied by primary flight symbology. This segmentation allows both types of information to be displayed simultaneously without mutual obscuration, maintaining clear visibility of landing-critical information while preserving the overall display architecture

AI summary
A display system for an aircraft includes a processing unit configured to determine runway lighting information for runway lighting associated with a selected runway and to generate display commands based on the runway lighting information. The runway lighting is located at a first location relative to the selected runway. The display system further includes a display device coupled the processing unit for receiving the display commands and operable to selectively render first symbology representing the runway lighting information at a second location relative to the selected runway.
