1991年东北空管局从意大利ALENIA 公司引进了一套空中交通管制一、二次雷达系统。该系统为空中交通管制人员提供了直观的飞行状况和空中交通管制服务,对提高航班正常率、缩小飞行间距及保障飞行安全有着极其重要的作用。在这套雷达中,雷达信息重放系统作为其功能之一,占据着十分重要的地位。它不仅可以作为管制人员进行学习,提高管制水平的最直观的教材,更是检查事故原因及事故征候的第一手材料。然而,在沈阳区域管制的三个显示终端中,只有 A 席位一个显示器有这种重放功能系统。一旦该
In 1991, the Northeast Air Traffic Control Authority introduced a set of air traffic control primary and secondary radar systems from ALENIA Italia. The system provides air traffic controllers with visual flight status and air traffic control services. It plays an extremely important role in raising the normal rate of flights, reducing flight distances and ensuring flight safety. In this set of radars, radar information replay system occupies a very important position as one of its functions. It can not only be used as a control staff to learn, improve the level of control of the most intuitive textbooks, but also check the cause of accidents and first-hand information on incidents. However, of the three display terminals regulated by the Shenyang area, only one A-seat display has such a playback function system. Once that
