由于在海洋空域无法实现雷达和VHF通信的覆盖,日本东京ACC的海洋飞行的空中交通管制不得不依靠基于飞行计划和飞行员报告的传统的程序管制系统。这就意味着,随着海上飞行量的增加,管制员的工作量也同时增加,而且在保持飞机间隔和有效地使用海洋空域方面出现了许多问题。为此日本开发了海洋空中交通管制数据处理系统(ODP)。采用按飞行计划由计算机计算并显示的仿真雷达的办法来协助海洋地区的ATC。它为管制员提供飞机识别、位置、速度和高度等连续的显示。这些数据是从飞行计 Owing to the inability of radar and VHF communications to be covered in the airspace of the sea, air traffic control over ocean-going aircrafts in Tokyo, Japan ACC had to rely on conventional procedural controls based on flight plans and pilot reports. This means that as the amount of air traffic at sea increases, the controller’s workload also increases, and there are many problems with maintaining aircraft separation and using the airspace airspace effectively. To this end Japan has developed the Marine Air Traffic Control Data Processing System (ODP). The use of simulated radars calculated and displayed on a flight plan by computer is used to assist ATCs in the maritime area. It provides controllers with continuous display of aircraft identification, position, speed and altitude. The data is from the flight meter
