A Novel Rerouting Planning Model for the Terminal Arrival Routes under the Influence of Convective Weather

Abstract

Under convective weather conditions, aircraft rerouting in terminal airspace is essential to ensure flight safety and reduce air traffic delays. Traditional air traffic rerouting approaches do not combine convective weather information using radar image recognition with controller workload, additional fuel consumption, delay loss, time cost, and route length at terminal airspace in tactical ATFM phase for exact rerouting decision. In accordance with the safety and economic principles of the route network in terminal airspace and in consideration of the changes in the speed and height of aircraft in terminal airspace, a multiobjective rerouting planning model is established in this study for terminal airspace under convective weather conditions in tactical air traffic flow management phase. Then traffic simulation is conducted to analyze the capacity and delays of the rerouting in the approach path in Shanghai terminal area. Experimental results indicate that this model can increase airspace capacity and operational efficiency of air traffic compared with the traditional air traffic rerouting approaches.

Volcanic Ash Region Path Planning Based on Improved A-Star Algorithm

“…Zhang et al established a multiobjective rerouting planning model in this study for terminal airspace under convective weather conditions in the tactical air traffic flow management phase [7]. Although the meteorological factors were objectively considered and the model was established, the selection of the model's influencing factors will have a greater impact on the results, and careful selection is required.…”

Insights of Models for Air Traffic Management System

“…In addition, environmental has become the main cause of delays in fighting. The US Federal Aviation Administration (FAA) announced in-depth research that about 65 -75% of the combat delays over 15 minutes had a direct caused by weather conditions [6]. Due to the uncertainty of the weather forecast for terminal airspace, it is extremely difficult to estimate airport ability to devise effective traffic management strategies.…”

“…The end time of the weather-related ground delay system was 95 minutes earlier than the original scheduled land delay schedule, for the 12 airways covered by FAA's National airspace system (NAS) Plan published in 2008 and 2009 [4,5].For the next generation air transport systems, the FAA and the National Aeronautics and Space Administration are working to remove the negative impact of weather conditions on the NAS. We will also discuss the enhancement of integrated air traffic management by increasing the degree of automation and developing resources for decision support [6].Based on the weather radar echo and the 30-minute earlier short-term forecast, the FAA identified the weather-affected area of the air traffic management system to examine the effect of inclement weather conditions on route network analysis in the ATFM process. A network design was utilized to describe the entire environment, and the area influenced by extreme weather conditions was separated into 0-6 evaluations [7][8][9], spoke to by various colors.…”
