Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft-based weather radar systems face limitations in image quality and coverage due to low bandwidth constraints, often requiring reduced color palettes and image compression, which compromises the accuracy and relevance of weather data displayed to pilots, necessitating improved methods for displaying weather conditions and aviation events.
Innovation Solution
A method and system that selectively display weather data based on the aircraft's location, allowing for the reception and rendering of high-quality weather images using vector graphics, which can scale without loss of detail, and automatically adjust the display area to maintain relevant weather information in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If weather data is transmitted over low bandwidth links, then communication range and coverage are improved, but image quality and data accuracy deteriorate due to compression and reduced color palettes
Solution Approach 1:
The patent divides the weather display into multiple selectable display areas or regions of interest. Instead of transmitting the entire weather map at high resolution, the system segments the data and transmits only the relevant portions, reducing bandwidth requirements while maintaining image quality for the areas that matter most to the pilot.
Solution Approach 2:
The system applies different quality levels to different regions of the weather display. High-resolution, high-color-depth data is transmitted for selected display areas where weather information is most critical, while lower quality data is used for other regions, optimizing the balance between bandwidth efficiency and image quality.
2Quantity of substance
If image compression is applied to reduce data size, then bandwidth consumption is reduced, but display quality and detail accuracy deteriorate
Solution Approach 1:
The patent implements dynamic adjustment of display parameters based on flight conditions and pilot selections. The system can dynamically switch between different compression levels, color palettes, and display resolutions depending on the current operational context, allowing high quality when needed and data efficiency when appropriate.
Solution Approach 2:
The system changes multiple parameters simultaneously including color depth, resolution, compression ratio, and display area size based on selected weather products and flight conditions. This multi-parameter optimization allows the system to maintain image quality while reducing data size through coordinated parameter adjustments rather than single-parameter compromises.
3Device complexity
If conventional radar beam width is used, then system simplicity is maintained, but detection accuracy and weather identification capability deteriorate
Solution Approach 1:
The patent introduces additional dimensions to weather detection by incorporating satellite imagery, radar cross-section analysis, and multi-parameter weather products alongside traditional radar beam data. This multi-dimensional approach enhances weather identification capability without requiring fundamental changes to the core radar system architecture.

AI summary
A method of selectively displaying an image representative of a weather condition in relation to an aircraft includes selecting, on a display screen, a display area to display weather data based on the location of the aircraft, selecting a weather condition to display from among a plurality of weather conditions, determining if any weather conditions are available to be displayed outside the selected display area and if the weather conditions should be displayed outside the selected display area based on the location of the aircraft and the severity of the non-selected weather conditions, receiving, from a weather data source, weather data representative of the selected weather condition with respect to the selected display area, and receiving weather data representative of weather conditions that should be displayed outside the selected display area, the weather data including location data for the weather conditions, and displaying the image representative of the selected weather condition within the selected display area and the weather conditions that should be displayed outside the selected display area, the image based on the received weather data.
