Wake Turbulence Icon Generation for Aircraft Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively alert pilots to potential wake turbulence encounters, particularly for smaller aircraft, which can lead to loss of control and safety risks, prompting the need for improved wake turbulence information presentation.
Innovation Solution
A system on the aircraft processes position, heading, and wind information to determine if a wake condition exists and generates a wake icon, with customizable colors, intensities, and patterns to represent the severity and extent of wake turbulence, displayed only when relevant to the aircraft's flight path, minimizing clutter and alerting pilots to pertinent turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wake turbulence information is displayed for all aircraft, then pilot awareness of potential wake turbulence is improved, but display clutter increases making it difficult to identify pertinent threats
Solution Approach 1:
The display system segments wake turbulence information by filtering and categorizing aircraft based on their wake turbulence characteristics. Only aircraft meeting specific criteria (size, weight, altitude, proximity) are displayed, dividing the overall information set into relevant and irrelevant segments. This allows pilots to see only the wake turbulence threats that pose actual risks to their flight.
Solution Approach 2:
The system applies different display characteristics to different segments of wake turbulence information. Pertinent wake turbulence from aircraft meeting the criteria is displayed with specific visual properties (icons, colors, symbols), while non-pertinent information is suppressed. This local differentiation ensures that critical information stands out without being overwhelmed by irrelevant data.
2Reliability
If wake turbulence alerts are provided for all aircraft, then safety is improved, but false alerts increase causing pilot distraction
Solution Approach 1:
The system performs preliminary filtering and assessment of aircraft before generating wake turbulence alerts. By evaluating aircraft size, weight, altitude, and proximity in advance, the system pre-identifies which aircraft are likely to pose wake turbulence threats. This preliminary action ensures that only aircraft with genuine wake turbulence potential trigger alerts, reducing false positives and maintaining high signal-to-noise ratio.
Solution Approach 2:
The system continuously monitors aircraft parameters and dynamically adjusts alert generation based on real-time conditions. By comparing current aircraft states against established criteria and updating the display accordingly, the system provides accurate feedback about actual wake turbulence risks, minimizing false alerts while maintaining comprehensive safety monitoring.
3Ease of operation
If detailed wake turbulence information is displayed, then pilot decision-making is improved, but information processing time increases
Solution Approach 1:
The system extracts only the most critical wake turbulence information needed for pilot decision-making. By isolating and displaying only pertinent parameters (such as aircraft type, relative position, and wake severity indicators) while omitting extraneous data, the system provides sufficient information for safe decisions without requiring pilots to process unnecessary details.
Solution Approach 2:
The system uses color-coding and visual differentiation to convey wake turbulence severity and urgency. Different colors or visual patterns indicate different levels of threat, allowing pilots to quickly assess situations and make decisions based on intuitive visual cues rather than analyzing numerical data. This visual encoding reduces information processing time while maintaining comprehensive safety information.

AI summary
Systems and methods for improving the presentation of wake turbulence information. A processor located on an ownship receives position, heading and type information of another aircraft and position and heading information of the ownship. The processor determines if a possible wake condition exists from the other aircraft based on at least a portion of the received information and at least one predefined threshold and generates a wake icon if a wake condition is determined to exist. The wake condition exists when the ownship's altitude is below a first threshold altitude and above a second threshold altitude, wherein the first and second threshold altitudes are based on the other aircraft's altitude.
