航機軌跡於到場管制之應用分析

Abstract

本研究運用臺灣桃園國際機場實際航機軌跡之資料分析，將航機到場管制作業進一步明確化，以增進航機航行之安全及效率。經由分析現有傳統離到場程序之路線結構，歸納出容易發生航機衝突問題之潛在區域，再彙整實際離到場航機之飛行軌跡資料，運用統計分析方式求得排解航機衝突之可能方法，並據以規劃明確的到場管制方式，最後透過案例模擬分析排解衝突之可行性及航機通過時間之改善效益。結論發現，透過實際航機軌跡之分析，可歸納出共六條到場路線及三種不同的到場速度供北面到場之航機使用，在其它航機航情為已知前提下透過路線及速度選擇，可有效排解航機衝突，同時減少航機之通過時間，增進航機飛行效率。

In this research, aircraft trajectory data is used to create a detailed arrival control for Taiwan Taoyuan International Airport. The current arrival and departure routes are analyzed to conclude several possible aircraft conflict area. Thereafter, aircraft trajectory data are gathered and statistical methods are applied for analyzing possible conflict resolutions. Such conflict resolution findings are used as the improved arrival profile, containing six designed routes and three speed/altitude profiles. With the proposed detailed-profiles and the known traffic situation, the simulation results demonstrated that the aircraft conflicts could be avoided as designed and the flight time were shortened if the arrival flights were properly handled.
