The increasing demand of civil aviation has resulted in air traffic congestion in the limited airspace. As a consequence, it causes problems in air traffic control. To effectively improve the airspace congestion and flight delay, segregation based on aircraft position and speed certainly is preferred to that of route-based, if the flexible routes based on the aircraft trajectories could be planned in limited airspace, and the flow management concept could be well implemented.
Based on aircraft trajectories, this research within Taipei Terminal Control Area build up the flow management. C ++ Builder 5 computer language was used to structure a simulation model to simulate the flexible routes which was planned for flight arrival. With parameters calculated from the ATC radar data, the model applies the first come first serve rule under the aircraft separate constraint and shortest path principle.
The simulate results showed that, with current air traffic, performance of the flying distance and time under the flexible-route was reduced by 8.5% and 12.1% respectively, when it was compared to that of the existing condition. In the case of 20% air traffic increase, in addition to the flying distance and time reduced by 5.9% and 8.5% respectively, the flight holding time was also reduced 30%. This suggests that with the flexible routes, flights can be more smoothly operated. Controller’s load could be reduced, and pilots can also approach and land aircrafts efficiently in accordance with the guided routes. |
