With the longest runway of 5.5 kilometers in the world, it is still difficult for Qamdo Bangda Airport to take off and land. Why?

With the accelerated pace of people's life and the improvement of living standards, long-distance business trips or travel have become the first choice for many people. Moreover, the general airport is not too far from the urban area, and the whole journey is much faster than the high-speed rail. However, Changdu Bonda Airport in Changdu City, Xizang Autonomous Region, China is an exception. Changdu Bangda Airport is located in the north of Changdu Town 136 km, and is known as "the civil airport farthest from the urban area in the world".

The runway of China domestic civil aviation airport is generally designed at about 3,500m, which is enough for most aircraft, with the exception of Qamdo Bonda Airport. Its runway is 5km long and it is one of the longest civil airports in the world, which is 1.7km longer than the Capital Airport, but it is also called "the worst civil airport in the world".

Changdu airport is as high as 4334 meters above sea level. It used to be the highest airport in the world, and now it ranks second in the world. In addition, in winter, the temperature of Changdu Airport is kept at around minus 20℃ for a long time, and the wind speed is above 30 meters per second. And the air density over the airport is only 50% of the sea level. In a series of dangerous environments such as extremely high altitude, cold, lack of oxygen, untenable gale, snowstorm and hail, even the most skilled and experienced pilots may not be able to land at this airport casually, because this is one of the most difficult airports in the world, and the pressure on pilots is enormous, so even if the runway here is 5 kilometers, it is still difficult to complete the take-off and landing.

Although there are such steep geographical conditions here, it is also an important area where Tibet borders Yunnan, Sichuan and Qinghai provinces, so this airport is very convenient and necessary.

Now this airport flies between Chengdu, Tianjin, Chongqing and other important cities in China. It not only eases the traffic and brings more convenience to the local people, but also promotes the development of the local economy, so that more local people can go out to work and get better development opportunities, and the people of this city can also get more opportunities. Now this airport has been in operation for many years. I hope the most dangerous airport in the world can be safe forever, so that more people can enjoy the beauty of Qamdo!
