Research on Aircraft Pushback Procedure in Busy Airport

The aircraft pushback is an important aspect of airport surface management and is one of the key factors affecting operation efficiency of apron. The problem of aircraft pushback in busy airports is studied in this paper. On the basis of the analysis on the process of aircraft pushback, the aircraft pushback procedure is designed to solve the influence of airport blind spot and the conflict of pushback. Mainly using the shortest sliding time as the optimization objectives, a model of gate position combination is set up and a hierarchy iteration algorithm is designed to solve the model. Finally, it is shown through instances that the aircraft pushback procedure can effectively reduce the conflict and increase the level of surface management and operation.
