Abstract:

In order to solve the safety and efficiency of hub airport aprons during full load or even overload operation of apron stands, the Kinematics model and Monte Carlo trajectory deviation method were used to study the allocation of temporary stands for aircraft. The kinematics model of aircraft taxing on an apron area was established by analyzing the influence of B configuration and docking corridor bridge. The Monte Carlo trajectory deviation model of aircraft in a fixed stand was put forward based on discrete statistical theory. Combined with the nominal trajectory and deviation area of Matlab simulation, the apron operation conflict probability model was constructed with temporary stands. The case verification of 30 normal stands and 4 hot spots on taxiway G of Changsha Huanghua Airport was carried out. The results show that compared with the traditional manual experience scheme, the Monte Carlo based fluorescence detection method can improve the accuracy judgment of operation conflict area, reduce the amount of affected fixed stands by 10%, interference route for push-out by 50% and conflict probability by 56.8%. Three groups of head-to-head gliding are eliminated. The research is helpful in optimizing the allocation of temporary stands and reducing risk of operation conflict.
