Solution Overview

Problem

Existing flight delay prediction systems lack accuracy and fail to provide proactive management strategies, leading to significant disruptions and costs in the aviation industry.

Innovation Solution

A method and system that utilize a set of predictive models to break down flight arrival time prediction into three phases: departure delay, flight time to entry point of a standard terminal arrival route, and time from entry point to landing, using features like weather, aircraft type, and wake vortex spacing, trained with ensemble learning models like artificial neural networks and random forests.

1Measurement precision

If existing flight delay prediction systems are used, then flight arrival time can be predicted, but the prediction accuracy is insufficient leading to significant disruptions and costs

Engineering Contradiction:
Improveprediction accuracyVSAvoidflight delays
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The flight arrival time prediction is divided into three distinct phases: departure delay prediction, flight time to entry point prediction, and time from entry point to landing prediction. Each phase is modeled separately using dedicated predictive models, allowing for more precise analysis and prediction of each segment while accounting for specific factors relevant to that phase.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs predictions proactively before flights occur by processing features such as weather conditions, aircraft type, wake vortex spacing, and other relevant data through ensemble learning models. This preliminary prediction enables advance preparation and mitigation strategies rather than reactive responses after delays occur.

Solution Approach 1:

The complex prediction system is segmented into three separate predictive models, each handling a specific phase of flight. This modular approach manages complexity by dividing the overall system into smaller, more manageable components while maintaining high prediction accuracy through specialized modeling of each phase.

Inventive Principle:

AI summary

A system and computer implemented method for predicting a flight arrival time of a given aircraft flight, between an origin airport and a destination airport, of a given aircraft based on a set of features is disclosed. The method comprises determining a predicted time delay of a flight departure time of the given aircraft flight from the origin airport by processing a first plurality of features of the set of features using a first predictive model; determining a predicted time duration of the given aircraft flight from the origin airport to an entry point of a standard terminal arrival route for the destination airport; and determining a predicted time duration of the given aircraft flight from the entry point of the standard terminal arrival route for the destination airport to landing on a runway of the destination airport.
