Analysis of LED landing light system for airport and runway

1, runway edge lights:

Runway edge lights must be installed on the runway at the runway length along the edge line parallel with the runway centerline offset on the runway at or beyond the edge of not more than 3 meters installed, the color of the light is a variable white, yellow lights tail distance of 600 meters or half of the runway, the smaller the general.

Figure: runway side light is constant light white, indicating the runway on both sides of the border.

Note:

The distance between the runway lights on the runway of each A. is not the same, so when the pilot uses the visibility of the runway edge lights to estimate the visibility of the airport runway edge lights, use this value to estimate the visibility.

In the case of B. moving in the entrance of the runway, the runway side light from the start point of the runway to the inside of the runway entrance is displayed in the red direction.

One end of the C. from the beginning of the end of the runway takeoff, 600m or the length of the runway 1/3 (two from the small value) this section of the runway edge lights display yellow.

2, runway entrance lights:

Installed at the end of the runway or near the end of the runway is not more than 3 meters, the color of the light is green. Runway entrance lights must be perpendicular to the runway axis. Runway entrance lights not less than 6. All kinds of precision into the runway to install a runway entrance lights, lamp spacing of 3 meters.

3, runway end light:

The end of the runway lights arranged on the side of the runway lights at the end of the runway, designed for unidirectional constant light emits red light to the direction of the runway, to help the driver to identify the end of the runway.

4, runway centerline lights:

General 2, 3 types of precision into the runway must be installed in the middle of the runway lights. These lights should be 5 M 7 m 15 m or 30 m longitudinally spaced evenly from the runway entrance to the end of the runway centerline. From the entrance to the runway 900 meters away from the end of the runway, must be fixed by white light variable; from the end of the runway 900 meters to 300 meters from the end of the runway, is red and white from the variable; the end of the runway 300 meters until the end of the runway is red.

Figure: the runway centerline lights are used to indicate the central line of the runway, usually along the central line of the runway, but the actual installation is often located in the middle of the runway on the same side of the line a short distance. The driver in control plane alignment line roll, this distance can be ignored.

Note:

In the case of a runway length of less than 1800 m, from the midpoint of the usable landing length to the end of the runway

300 at the center of the runway at the center of the m light alternately variable white light and red light.

5, runway grounding strip lights:

All 2, 3 types of precision into the runway of the ground, must be set to the ground strip lights, light color variable white. From the runway entrance from the vertical extension to 900 meters, only when the runway length is less than 1800 meters, the distance is shortened to the middle point so that it does not exceed the runway. The ground floor lamp must be symmetrically arranged on both sides of the central line of the runway, and the horizontal distance between the inner lamps shall be not less than 18 meters, and shall not be greater than 22.5 meters, with an average of about 18 meters. The ground light is composed of a plurality of horizontally arranged lamp sets (i.e. a row lamp). Each row of lights must be composed of at least 3 lamps with a distance of not more than 1.5 meters, and the longitudinal distance between each row of lamps is about 30 meters.

Note:

Not all of the runways have ground lights

6, rapid exit taxiway indicator light:

Rapid exit taxiway indicator is one-way yellow constant light lamp, arranged on the runway centerline rapid exit taxiway connecting the side of the runway, to provide information on the distance from the nearest rapid exit taxiway for runway to the driver, in a low visibility down to better understand the location of the aircraft. Reasonable use of the brake, in order to obtain a more efficient landing and departure track speed.

Figure: rapid exit taxiway indicator is arranged in the distance from the initial crossing 300 meters, yellow light is the 3 side by side; in the distance from the yellow light crossing 200 meters set 2 side-by-side; after the distance from the crossing of 100 meters and a single yellow light.

7, stop lights:

Constant light stop lamp emits red light for the way toward the direction of the runway, to help the driver to stop at night road recognition.

8, the runway lights:

Runway U-turn lawn lamp is one-way constant light green light, provide continuous guidance for the driver in low visibility conditions, so that the aircraft can carry 180 degrees turn and aligned with the runway centerline.
