Solution Overview

Problem

Aircraft wake turbulence poses a safety risk to other aircraft due to its magnitude, which is influenced by the size and speed of the generating aircraft, and existing methods to mitigate this risk, such as spacing or altering flight paths, lead to inefficiencies in air traffic management and increased fuel consumption.

Innovation Solution

A flight management system that includes a receiving module for data communication, a routing module for predicting and modeling wake turbulence vortices in 4D space, and an advisory module for alerting pilots or air traffic control to adjust flight paths to avoid or mitigate the effects of wake turbulence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aircraft maintain larger spacing or alter flight paths to avoid wake turbulence, then safety is improved, but air traffic efficiency deteriorates and fuel consumption increases

Engineering Contradiction:
ImprovesafetyVSAvoidair traffic efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary modeling and prediction of wake turbulence vortices before aircraft encounter them. By calculating vortex trajectories and dissipation rates in advance using environmental data and aircraft parameters, the system enables proactive safety decisions rather than reactive spacing adjustments, thereby maintaining safety while improving traffic efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors actual wake turbulence conditions and compares them with predicted values. This feedback mechanism allows dynamic adjustment of flight paths and spacing recommendations, optimizing both safety and efficiency by adapting to real-time conditions rather than relying on fixed conservative spacing rules

Inventive Principle:
Principle #23Feedback

Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

By predicting vortex dissipation rates and trajectories in advance using environmental conditions and aircraft parameters, the system enables fuel-efficient flight path planning. Aircraft can maintain optimal spacing based on actual turbulence decay rather than conservative fixed distances, reducing unnecessary fuel consumption while ensuring safety

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts spacing and flight path recommendations based on changing parameters such as vortex dissipation rate, wind conditions, and aircraft weight. This allows continuous optimization of fuel consumption by matching separation distances to actual turbulence conditions rather than applying fixed conservative margins

Inventive Principle:
Principle #35Parameter changes

3Reliability

If conservative spacing between aircraft is maintained to avoid wake turbulence, then safety is improved, but the need for excessive spacing reduces air traffic capacity

Engineering Contradiction:

Solution Approach 1:

The system calculates wake turbulence vortex trajectories and dissipation characteristics in advance based on aircraft parameters and environmental conditions. This preliminary analysis enables air traffic control to approve tighter spacing where conditions permit, thereby increasing traffic capacity while maintaining safety through scientifically-based predictions rather than conservative fixed rules

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides dynamic spacing recommendations that adapt to changing flight conditions, vortex dissipation rates, and environmental factors. This dynamic approach replaces static conservative spacing rules with flexible, condition-based separation standards, maximizing air traffic capacity while ensuring safety through continuous assessment of actual turbulence risks

Inventive Principle:

AI summary

A method and apparatus for recording flight information of aircraft (10, 14), such as position, mass, or type, in order to record the position of a wake turbulence (86) of the aircraft (10, 14). Weather information can be recorded as affecting the wake turbulence (86). Such information can be provided into a model or algorithm to determine a path of a wake turbulence (86). An aircraft (14) on a flight path (84) to encounter the wake turbulence (86) can determine a vortex magnitude of the wake turbulence (86) and determine if an advisory alert needs to be provided if the vortex magnitude satisfies a predetermined threshold.
