在雷达屏幕上，当飞机数量过多时，显示飞机呼号，高度的标牌就会重叠在一起，影响管制人员进行指挥。这是我编的一个小程序，可拖动飞机标牌到任意位置，避免飞机标牌重叠的问题。对开发民航系统的IT人员会有帮助。-On the radar screen, when the number of aircraft over time, indicating the aircraft call sign, signs will be a high degree of overlap with the impact of command and control personnel. This is what I made a small program can drag the aircraft to any location signs to avoid the problem of overlapping signs aircraft. On the development of civil aviation system will help the IT staff.
