Airborne Weather Radar Inference for Aviation Display Depiction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aviation weather systems rely on ground-based predictions and fail to accurately indicate specific weather threats to aircraft, as they often cover large areas and do not account for turbulence, hail, or lightning, which can be present in storms with little precipitation or electrical activity.
Innovation Solution
An airborne weather radar system with processing electronics that infers weather threats using algorithms based on wind speed, wind direction, size of weather cells, temperature, reflectivity, and changes in echo top altitude, displaying these threats on an aviation display to alert pilots of potential hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If ground-based weather prediction systems are used, then broad weather coverage is provided, but specific weather threat accuracy to aircraft is poor
Solution Approach 1:
The patent segments the broad weather coverage into specific weather cells and individual threats within each cell. By dividing the large coverage area into discrete, analyzable units (weather cells with specific parameters like reflectivity, temperature, wind speed), the system maintains comprehensive coverage while achieving precise threat identification for each segment.
Solution Approach 2:
The patent adds a new dimension of analysis by incorporating multiple parameters (reflectivity, temperature, wind speed, echo top altitude) and their relationships. This multi-dimensional approach transforms the single-dimension ground-based prediction into a comprehensive three-dimensional weather threat assessment that accurately identifies specific hazards to aircraft.
2Quantity of substance
If weather radar detects precipitation, then rainfall areas are identified, but other weather threats like turbulence and hail are missed
Solution Approach 1:
The patent makes the weather radar system universal by enabling it to detect multiple types of weather threats simultaneously. By analyzing relationships between different parameters (reflectivity indicating hail potential, temperature indicating turbulence, wind speed indicating storm intensity), the single radar system performs multiple detection functions beyond just precipitation.
Solution Approach 2:
The patent uses parameter relationships as intermediaries to infer hidden weather threats. Since radar cannot directly detect turbulence or hail, it uses measurable parameters (reflectivity, temperature, wind speed) as intermediaries that correlate with these threats, allowing indirect detection through algorithmic analysis of parameter relationships.
3Measurement precision
If lightning detectors are used, then lightning strikes are detected, but induced electrical threats are not identified
Solution Approach 1:
The patent performs preliminary detection of electrical threats by analyzing reflectivity and temperature parameters before lightning actually occurs. By identifying conditions favorable for electrical activity (high reflectivity, specific temperature ranges) in advance, the system warns pilots of potential induced lightning threats before they materialize.
4Measurement precision
If algorithms analyze multiple weather parameters, then weather threat accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service by having the system automatically analyze multiple parameters and their relationships through embedded algorithms. The processing electronics autonomously evaluate reflectivity, temperature, wind speed, and echo top altitude relationships without requiring manual intervention, achieving high accuracy while managing complexity through automated decision-making.

AI summary
A method for indicating a weather threat to an aircraft is provided. The method includes inferring a weather threat to an aircraft and causing an image to be displayed on an aviation display in response to a determination by aircraft processing electronics that the inferred weather threat to the aircraft is greater than a measured weather threat to the aircraft.
