Aircraft Go-Around Detection Employing Open Source ADS-B Data

Go-around is the process of aborting the landing of an aircraft, which can induce air traffic disruptions and collateral delays, particularly in busy airspace, although they are rare. A go-around detection method is presented using the open source ADS-B data provided by the OpenSky Network. Firstly, the flight phase change point is defined as the go-around indicator, and then the changes in the altitude and vertical velocity of the aircraft within 60 seconds after the change point is to determine whether a go-around has occurred. The experimental results are given, which applies the approach data of Chongqing Jiangbei International Airport (ZUCK) in China for the past two months. Analysis shown that the method has advantages over other methods in detecting go-arounds with very few misses and almost no false alarms. This method is also universal and suitable for large airports covered by ADS-B around the world.
