Ground lighting equipment refers to various navigational aids and lighting lights installed at high altitudes within the airport and near obstacles for the safety of aircraft takeoff, landing, taxiing, and parking. Among them, there are mainly obstacle lights, airport lights, runway identification lights, approach lighting systems, visual approach slope indication systems, grounding strip lights, runway lighting systems, taxiway lighting systems, night emergency lights, and apron lighting lights

Obstacle lights

Red obstacle lights that indicate danger and are not allowed to pass, installed at the commanding heights of the flight area, such as mountain tops, tower tops, chimney tops, and high-rise building roofs.

. Obstacles with a height of less than 50 meters are only equipped with a red light on top. Obstacles exceeding 50 meters are equipped with a string of red lights to indicate their three-dimensional height. The elevated bridge near the airport is also equipped with red lights at a series of high points, indicating the span of the bridge

Airport Lighthouse

Pilots need to accurately determine the location of the airport when flying to their destination.

. The airport lighthouse is the first target that pilots need to find from a distance. It is a flickering device with strong brightness. The lights at civil airports are white green white green, flashing 12 times per minute. If the airport is near the water area, change the green color to yellow. Some countries' military airports have changed the color from white once to fast white twice, becoming white, white green white, and white green. During the day, the airport lighthouse flickers continuously, indicating poor visibility and cloud base height, and the need to approach according to the instrument flight

Runway identification lights

The pilot must see the runway very early before entering it, so that he has ample time to prepare for approach.

. If there are many houses and buildings around the airport or if the airport is near a large city, it is even more necessary to see the runway in advance. Runway identification lights are lighting devices with strong brightness and high flashing frequency installed on the ground at both ends of the runway. Large airports may have multiple runways, and in order for pilots to find the landing runway, all runway identification lights on other runways are turned off

Wind direction light indicator

It is actually a wind vane that stays on during night flight.

Approach Lights

In general, after the aircraft arrives at the airport, it takes the runway identification lights at both ends of the airport as the center line, circles around the field, and then aligns with the runway, gradually landing. But when the weather is particularly bad, it is necessary to land directly at the runway. For this reason, some large airports have lighting access roads. It is an extension of the runway, and the pilot can pilot the aircraft to gradually approach the ground along this approach path until entering the runway. The length of the approach lane can sometimes reach 1000 meters, and its width is equivalent to that of the runway, all composed of lighting. Firstly, there are rows of white approach lights installed on the extension light rack of the runway centerline. After passing about two-thirds of the approach road, there are white approach lights arranged in a chessboard shape. Finally, there is a row of red tail lights on the approach road, indicating a distance of only about 20 meters from the runway entrance. Afterwards, the pilot flew into a row of green runway end entry lights. This is a relatively complex lighting system, but in fact, the approach lighting used at each airport is not entirely the same. But the overall purpose is to use lights to indicate to the pilot the centerline of the approach lane, the starting point of the approach lane, and the starting point of the runway

Glide light

The glide light indicates whether the pilot's glide angle is correct.

. Two sets of lights are installed on both sides of the runway, one of which is a close range light located approximately 250 meters from the end of the runway; The other group is from the end of the runway
