The drone subculture in silicon valley reflects the widening use of unpiloted aircraft by the u. s.military and law-enforcement agencies .
硅谷的无人机亚文化体现出美国军方和执法机构所用的无人机的应用范围得到了扩大。
Airport procedures would also have to be dramatically revised to accommodate unpiloted planes .
机场程序也需要大幅修改,以适应无人驾驶机。
As a result , more widespread use of unpiloted planes would require a complete overhaul of air-traffic-control procedures , both in the air and on the ground .
因此,无人驾驶飞机的广泛使用要求彻底修检地面和空中的控制程序。
But it would open up the skies to far more traffic than can be handled by the current system-and it would allow piloted and unpiloted planes to co-exist more easily .
