在某些区域（主要是机场附近），受管制的空域一直延伸到距地面215米之上，而且在紧邻机场的区域，控制区域一直延伸到地表。
In certain areas, mainly near airports, controlled airspace extends down to 215m above the ground, and, in the immediate vicinity of an airport, all the way down to the surface.
在其他地方，在不受控制的空域，飞行员受到的管制较少。
Elsewhere, in uncontrolled airspace, pilots are bound by fewer regulations.
舰载传感器跟踪的实际飞行活动时，ATAC系统自动关连空中任务命令和空域控制命令中的飞行计划任务数据。
ATAC performs an automatic correlation of the planned mission flight data in the Air Tasking Orders and Airspace Control Orders with actual flight activity tracked by the ship's sensors.
BBC指出，现有的携弹无人驾驶飞机，像装备了“地狱火”（Hellfire）导弹的“掠夺者”（Predator）无人机，只在盟军控制的空域有用。
Existing unmanned weaponized aircraft, like Predator drones that carry Hellfire missiles, are only usable in allied-controlled airspace, BBC notes.
它有限的有效负荷是一个不利因素；它的使用将会使陆军的空域指挥与控制复杂化。
Its limited payload will be a negative factor. Its use will complicate Army airspace command and control.
因此，研究新体制的三轴雷达的驱动结构及控制方案以实现大于半球的全空域无缝隙连续跟踪就变得十分必要。
So it is necessary to study the driving structure and control scheme of new system radar in order to track continuously in whole hemisphere without blind zone.
阐明了针对大空域机动反舰导弹飞行空域大、速度变换范围大的特点，采用增益调度的方法设计其控制系统。
For Large aerospace maneuvering anti-ship missiles(LAMASM), which fly in large aerospace with velocity varies in large range, a gain schedule autopilot is designed.
为了实现反舰导弹的大空域变轨，提出了一种三维虚拟目标比例导引律。该导引律利用简单的控制指令就能控制导弹完成复杂的大空域变轨。
In order to realize large airspace transfer orbital trajectory of an anti-ship missile, a 3-dimensional virtual target's proportional navigation guidance (PNG) law is proposed.
