| Summary | This study tries to develop an on-line flow control preliminary system for the Taiwan CAA (Civil Aeronautics Administration). This system can predict and display the estimated flight arrivals and departures in selected airports and the associated available airport capacities during the next two hours. The two-hour time window is determined based on the flight time duration of domestic flights in Taiwan. This system includes four databases and five modules: (1) static flow distribution database, (2) dynamic flow distribution database, (3) flight times database, (4) capacities database, (5) input, (6) flow estimation, (7) available capacities estimation, (8) suggested departure time intervals for each associated airport, and (9) user interface. This system has gone through a thorough field test. The results show that the overall system performs quite well with good quality of input data. However, the available input data is not precise enough and makes it difficult to conduct tight control. This problem is especially acute in Taiwan due to its short domestic flight times. A flow control system is still needed in the future, thus how to obtain real time and accurate flight data especially for pre flight information will be an important task. If pre-departure clearance is via datalink, it may be helpful for improving the data quality partially. Due to the constraints of the real world, it is suggested to develop a simulation model for further evaluating the performance of departure sequencing algorithm. This system could be extended to provide information for the airline to make decisions regarding real time flight dispatching and scheduling. |
