The street light is too bright and the highway frequency is regarded as the landing runway.

The tourist season of “Golden September and Silver 10” has come to an end, and after the end of the “11 Golden Week”, there will be no other holidays before the end of the year. Therefore, with the arrival of the off-season, the ticket price discount will also follow. The letter opens the homepage of several air ticket booking websites, which are everywhere advertisements for discounts of major airlines. In the peak season, it is difficult to find the ticket below 30%, which is also “popular”, and the ticket price war is once again “returning”. On several air ticket booking websites, you can see that Tianjin and Shenzhen and Guangzhou have two flights with higher attendance rates, which will have a “diving price” of 1.9 fold on November 17 and 18, only 350 yuan and 320. The fare of the yuan can be described as a discount to the "bottom", and compared with the lowest price of 3.6 percent in the first ten days of October, the public can save at least 300 yuan if they book tickets now. Look at another "hot" route? Shanghai, on November 17th, you only need 294 yuan to buy a low-priced ticket of 2.9 fold, and in the golden period of "Golden September, Silver 10", the fare must be at least 50% off. the above. Chengdu is also one of the destinations with a large passenger flow during the tourist season. The lowest fare on November 22 is 2.1 yuan and 319 yuan, which is obviously more favorable than the low discount of 4.6 percent and 705 yuan at the beginning of October.
In addition, several other popular routes such as Tianjin to Sanya can buy a low price of 3.7 yuan on November 7th; Tianjin to Nanjing in the off-season on November 15th only need 210 yuan and 2.4 fold to "get it." Similarly, in mid-November, Tianjin’s air tickets to Chongqing and Wuhan were also about 2% off, which is about 20% lower than the fares in September and October.
The Lukou Airport Expressway from Nanjing to Nanjing Lukou Airport is connected to the airport at the intersection of the machine and the 24" runway. When the night falls, the high pole lights and low pillar lights on the highway and the airport The approach lights and runway lights for the aircraft navigation on the runway were simultaneously opened. Some domestic routes have dropped to more than 100 yuan, while Guangzhou to the Maldives only cost more than 900 yuan.
Mr. Huang is an old pilot who has been flying for more than ten years and is mainly responsible for the flight of important domestic routes. When talking about the impact of the streetlights on the Lukou Airport Expressway on the landing of the airport plane, the old captain told the author an impressive thing: "A while ago, a pilot drove a large passenger plane of Air China, ready to be in the Lu The landing at the airport. Due to the better weather and visibility in the evening, the pilot used a method of visually assisting the landing of the lights when landing. However, because the airport is near the runway, the highway is very bright. The pilot once produced visual errors and mistakenly regarded the expressway as an airstrip. When the plane landed at a certain altitude, the controller of the air traffic control center was reminded that there was no danger." Huang said on the highway. Lights and airport runway lighting are really easy for pilots to produce viewing angle errors, and if not corrected in time, the consequences are unimaginable. According to the technical staff of the technical department of the Airport Expressway Street Light Management Office, the light bulbs used in the high-light and low-column lights on the expressway are imported from Italy. The high-pole lamp power is 1000W, and the low-column The power of the lamp is also 250W. At present, the light bulb used in the visual navigation light system at the airport has a power of 200W. Although the distance between the airport runway is only 60 meters and the distance between the lights on the highway is more than 100 meters, the pilot can't distinguish the distance between the lights and the lights whenever the plane is flying at a height of several kilometers or hundreds of meters. . A staff member with a high surname in the Technical Section of the Airport Express Street Light Management Office said that due to the high intensity of these lights, it is afraid of affecting the landing of the aircraft. Therefore, the management office covers the lights with a cover and at the same time tries to ensure the cars on the road. The traffic safety, but did not expect to have a certain impact on the landing of the aircraft. In 2000, the technical department of Lukou Airport made a request to the highway street lamp management office to adjust the lights on the road, but no matter how it was adjusted, these high-intensity lights and the reflections on the ground were all brought to the landing zone. Come to a certain impact.

Near the airport, "light pollution" is serious. An old pilot with more than ten years of driving experience believes that there should be another phenomenon that should not be ignored. At the Lukou Airport, some local departments and villagers built some buildings near the airport. Some lights were installed on the building, and some night-vision lights in the nearby villages were bright, which all had an impact on the landing of the aircraft.
A controller from the airport tower told the author that when the airport was opened in July 1997, according to the design regulations, there were requirements for the airport lights and other surrounding lights. Now some lights near the airport are in urgent need of cleaning. He said that the airports in cities across the country are connected by highways. Although there have been no accidents caused by misleading lights, they should be given sufficient attention and measures should be taken in time.
