Abstract:
A clustering algorithm and a probability statistics method were applied to different phases of a flight to analyze operation time during aircraft ground taxiing and airborne flight. And the clustering pattern, distribution characteristics and dynamically changing rules of the two phases were identified. Further, an estimate method was established to measure operation time of flight legs, with creative steps of calculating individual segment separately and then integrating them accordingly. The method can both objectively and dynamically measure operation time, and accurately ref lect real situation. It helps to better utilize airport slot resources and provides a strong support for air traffic flow management when scheduling flight plan in strategic and pretactic phases.
