Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional weather radar systems display only two-dimensional radar scans, then the display complexity remains low, but the ability to plan safe and efficient flight paths is insufficient
Solution Approach 1:
The system transitions from traditional two-dimensional radar scan displays to three-dimensional volumetric weather data visualization. This allows flight crews to view weather formations in their spatial context, enabling better assessment of flight path options and safety. The three-dimensional display shows weather cells with depth information, allowing pilots to understand vertical and horizontal extent of hazards simultaneously.
Solution Approach 2:
The weather data is segmented into multiple display modes including two-dimensional overhead profiles, vertical side profiles, and three-dimensional volumetric views. Each segmentation serves specific planning needs: overhead views for horizontal routing, vertical profiles for altitude decisions, and 3D views for spatial understanding. This modular approach maintains usability while enhancing capabilities.
2Measurement precision
If the system displays detailed three-dimensional weather information, then the weather detection precision improves, but the information processing complexity increases
Solution Approach 1:
The system pre-processes raw radar data into multiple useful representations before display. Three-dimensional weather data is pre-computed and stored in a structured format that can be quickly rendered in different views (overhead, vertical, volumetric). This preliminary processing reduces real-time computational burden while maintaining high precision weather information availability.
Solution Approach 2:
The system uses an intermediary data structure that bridges raw radar returns and various display requirements. This intermediate representation standardizes weather data in a way that can be efficiently converted to multiple display formats, reducing processing complexity while preserving measurement precision. The intermediary layer abstracts the complexity of raw radar data processing.
3Reliability
If the navigation system integrates multiple weather data sources, then the reliability of weather information improves, but the system complexity increases
Solution Approach 1:
The navigation system is designed to handle multiple weather data sources (onboard radar, ground-based radar, satellite data) through a unified processing architecture. A single system framework accommodates different data formats and sources, processing them consistently to produce reliable weather information. This universal approach improves reliability without proportionally increasing complexity.
Solution Approach 2:
The system incorporates feedback mechanisms that validate weather information across multiple sources and display modes. By allowing flight crews to switch between different data sources and view modes based on situation requirements, the system adapts to improve reliability while maintaining manageable complexity through user-controlled information flow.

AI summary
A computing system may mount on an ownship vehicle. The computing system may include a memory configured to store three-dimensional radar data indicating weather proximate to the ownship vehicle; a touchscreen; and processing circuitry. The processing circuitry is configured to output, for display by the touchscreen, a two-dimensional overhead profile of the weather proximate to the ownship vehicle; receive, from the touchscreen, an indication of a selected region of the weather proximate to the ownship vehicle; determine, based on the three-dimensional radar data, additional information corresponding to the selected region of the weather; and output, for display by the touchscreen, the two-dimensional overhead profile of the weather overlaid with an indication of the additional information about the selected region.
