approach light的用法详解
'
The English word “approach light” is a noun referring to a signal light used to facilitate the approach of an aircraft to a runway. It is typically located at the outer end of the runway and can be seen from a distance by approaching pilots.
There are three colors used for approach lights: red, green and white. The red light is known as the “outer marker” and it serves as the boundary between the approach and the runway. At this point, the pilot reduces speed and altitude in preparation for landing. The green light is known as the “middle marker” and it signals to the pilot that they should begin their descent. The white light is known as the “inner marker” and it signals to the pilot that they are at the runway.
In summary, the approach lights are an essential part of aviation safety and they help pilots navigate their way to the runway.
