TAWS Depiction on SVS Perspective Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current synthetic vision information systems do not provide sufficient obstacle characteristic details, such as size and shape, to aircrews during TAWS warnings, limiting their ability to determine appropriate course actions in imminent collision situations.
Innovation Solution
A display system and method that includes a graphic processing engine, terrain database, terrain awareness and warning system, and warning signal database, which generates and displays three-dimensional images with detailed terrain and obstacle information, allowing aircrews to visualize and navigate around obstacles effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional TAWS warning systems are used, then warning alerts are provided to aircrews, but sufficient obstacle characteristic details (size, shape, adjacent obstacles) are not provided
Solution Approach 1:
The patent combines the TAWS warning system with the SVS display system into an integrated display system. The processing circuit receives both TAWS warning signals and generates SVS imagery simultaneously, merging obstacle detection and visualization functions into a single unified system that provides both warning alerts and detailed obstacle characteristics without requiring separate independent systems
Solution Approach 2:
The patent transitions from traditional two-dimensional TAWS warning displays to three-dimensional synthetic vision imagery. By generating and displaying 3D obstacle representations with depth, size, and shape information, the system adds a spatial dimension to obstacle visualization, enabling aircrews to perceive obstacle characteristics more intuitively and comprehensively
2Reliability
If detailed obstacle information is provided through 3D imagery, then aircrew situational awareness is enhanced, but system processing requirements and complexity increase
Solution Approach 1:
The processing circuit is designed to perform multiple functions simultaneously: it processes terrain database information, generates synthetic vision imagery, receives TAWS warning signals, and displays integrated 3D obstacle representations. This multi-functional processing circuit reduces the need for separate dedicated systems for each function, managing complexity through consolidation while providing comprehensive obstacle information
Solution Approach 2:
The system uses the aircraft's existing sensor data and positioning information to automatically generate the synthetic vision imagery without requiring additional external sensors or complex processing equipment. The processing circuit leverages available data from the aircraft's navigation and sensor systems to create detailed obstacle visualizations, reducing overall system complexity
