Research On Optimization Of Arrival And Departure Routes For Environmental Impact In TMA

As the environmental protection concept deeply rooted in the hearts of the people,a higher demand had put for the control of atmospheric pollution,noise pollution,climate change and other environmental problems caused by aircraft,and had become the focus of all sectors of the community.Due to the low altitude and the short distance to the urban of flight,the environment impact had an amplification effect.Therefore,safe,environment-friendly and efficient terminal air traffic operation strategy had significance to promote green aviation sustainable development.This dissertation took environmental protection as core,put the route network path planning of the terminal area(TMA)as the breakthrough point,made a research on the optimization of arrival and departure routes for environment impact in TMA.Firstly,the dissertation qualitatively analyzed the impact of air traffic on environment and corresponding mitigation measures in TMA.Secondly,analyzed the forming mechanism,environmental impacts and evaluation methods of air emissions and aviation noise,which was the most critical influence factors,and introduced the noise affect the number of city residents as a quantitative index.Third,taking into account the flight operation characteristics and aircraft flight performance,as well as safety,economy,environment,the dissertation set up the optimization model of route path with air emissions and aviation noise as the targets,the example verified that the optimized route had reduced the environmental impact of air traffic operation.Then,from the traffic demand,optimizing resource utilization,the environment quality,built the evaluation system of route planning priority in TMA,and designed calculation model of the route planning priority to acquire the sequencing of the route network.Finally,considering the flight conflict among routes,proposed the routes conflict relief method,established the optimization model with the goal of minimizing the environmental impact of routes network,the example showed that the model could effectively reduce the environmental impact,and ensure the safety of the flight.
