摘要
仪表着陆系统通过地面信标台发射出的无线电信号,在距机场入口25NM、左右±10°、与地面夹角8°的空域范围内形成一个虚拟近场通道,为进近着陆的航空器提供精密的航向道信号与下滑道信号,使得飞机在飞行降落的过程中能够按照无线电信号的指引,准确、平稳的降落在跑道上,属于精密进近着陆的引导体系。
Instrument landing system radio signal that is emitted by the ground beacon in about 25 nm away from the entrance of the airport, plus or minus 10 °, 8 ° Angle with the ground to form a virtual near field within the limits of the airspace channels,, smooth landing on the runway, belongs to the precision approach landing guidance system.
