Aircraft Wind Shear Display System Using 3D Perspective View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft display systems do not provide comprehensive and intuitive weather information, particularly regarding wind shear zones, which can impact flight operations and pilot workload.
Innovation Solution
A vehicle system with a control unit that includes a weather module to identify wind shear zones, generate wind shear coordinate and characteristic data, and provide display commands for a three-dimensional forward perspective view or vertical situation display, along with an autopilot response module to generate commands for mitigating wind shear impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional display systems are used to show weather information, then the display is simple and easy to operate, but the weather information is incomplete and not intuitive
Solution Approach 1:
The patent transforms two-dimensional weather data into three-dimensional visual representations that match the spatial perception of pilots. Wind shear zones, terrain, and weather phenomena are displayed in 3D space with proper perspective, allowing pilots to intuitively understand weather conditions without complex data interpretation.
Solution Approach 2:
The display system integrates multiple functions into a single comprehensive display: weather information, terrain visualization, navigation data, and wind shear detection all appear together in the primary flight display. This multi-functional approach provides complete weather information without requiring separate specialized displays for each function.
2Loss of information
If comprehensive weather information is provided on displays, then situational awareness is improved, but pilot workload increases due to information overload
Solution Approach 1:
The system applies different visual characteristics to different weather phenomena based on their local properties. Wind shear zones are displayed with distinct symbology different from turbulence or precipitation, allowing pilots to quickly identify and differentiate between various weather conditions without processing uniform data formats.
Solution Approach 2:
The display uses color coding to represent different weather conditions and their intensities. Wind shear zones, terrain features, and weather phenomena are displayed in colors that provide immediate visual cues about their nature and severity, reducing the cognitive load required to interpret weather data.
3Reliability
If wind shear detection and display capabilities are added to the system, then flight safety is improved, but device complexity increases
Solution Approach 1:
The wind shear detection system is merged with the existing weather radar and display systems. The same antenna and signal processing hardware are used for both weather detection and wind shear identification, eliminating the need for separate dedicated wind shear equipment while maintaining enhanced safety capabilities.
Solution Approach 2:
The system uses its existing weather detection capabilities to automatically identify wind shear zones without requiring additional sensors or external data sources. The weather radar system serves dual purposes: traditional weather avoidance and wind shear detection, with the same hardware providing both functions through software processing.
