Research On Prediction Algorithm Of Aircraft Ground Waiting Time

The rapid development of the civil aviation industry causes a tremendous challenge to the airport, heavy traffic jams and sustained flight delays appear frequently in the peak of the flight flow or in adverse weather conditions. Launching control of aircraft is an important part of the process of flights' departing, and the accurate prediction of the time between aircrafts are launched at the tarmac and taking off, which is called aircraft ground waiting time is the basis for aircraft launch control.This article rooted in the reality, the aircraft ground waiting was separated into two parts which are the time spent in taxiways and the time aircrafts spend in the waiting area to take off. After building a taxiway node network system, which is based on topology plane of airport, achieving the path planning in line with the actual situation, the taxiway waiting time predictive model was built. By building a runway waiting queue, the takeoff waiting time prediction model was constructed; and. After all, based on the actual data of a large domestic hub airport, the algorithm was simulated, the results shows that the proposed algorithm has a high degree of verisimilitude.
