| 摘要： | The problem of mixing aircraft equipped with time-controlled guidance systems and unequipped aircraft in the terminal area has been investigated via a real-time air traffic control simulation. These four-dimensional (4D) guidance systems can predict and control the touchdown time of an aircraft to an accuracy of a few seconds throughout the descent. The objectives of this investigation were to (1) develop scheduling algorithms and operational procedures for various traffic mixes that ranged from 25 to 75 4D-equipped aircraft (2) examine the effect of time errors at 120 n. mi. from touchdown on touchdown time scheduling of the various mix conditions and (3) develop efficient algorithms and procedures to null the initial time errors prior to reaching the final control sector, 30 n. mi. from touchdown. Results indicate substantial reduction in controller workload and an increase in orderliness when more than 25 of the aircraft are equipped with 4D guidance systems initial random errors of up to or - 2 min can be handled via a single speed advisory issued in the arrival control sector, thus avoiding disruption of the time schedule. |
