The most dangerous airport in China is built in canyons, surrounded by mountains, flying only in the morning.

In the impression that the airport is built in a broad area, the terrain is relatively flat.
In the Qinghai Xizang Plateau, however, there is such an airport, which is located in the valley of the mountain, surrounded by a high mountain range of four or five kilometers above sea level. The plane is only in a narrow and curved river valley, and the narrow channel is less than 4 miles from the canyon ridge. Each flight takes off and lands. It is a thrilling journey.
This is the airport in Milin, Linzhi, Tibet.
Tibet is known as "the roof of the world". It is more than 4000 meters above sea level. The snow peak is high and the glacier is widely distributed. The holy and mysterious natural scenery attracts more and more tourists from home and abroad.

However, Tibet has been regarded by the international civil aviation community as the "air forbidden zone", which is recognized by the world as the most difficult airspace. Wind and sand, hail, thunderstorm and high wind are raging.
Among them, the most complicated weather conditions and the worst geographical environment are Linzhi.

Compared with those on the Qinghai Tibet Plateau, those three or four kilometers above sea level, the Linzhi Airport is not high, only 2949 meters, in the domestic civil airports in the altitude of twelfth.
However, the difficulty of Linzhi Airport's flight is China's first and even the most difficult airport in the world.

During World War II, Linzhi was a must for the famous "Hump route", when dozens of allied transport planes crashed in the mountains.

Linzhi Airport is 120 kilometers away from the "human last secret" - the Yarlung Zangbo River Grand Canyon, 450 kilometers from Lhasa.
Linzhi Milin airport is 50 kilometers from the town of Linzhi city government in Bayi Town. It is connected to a 45 kilometer Airport special highway, with a speed of 80 kilometers and a two-way four lane. It runs in November 5, 2015.

Linzhi has a low altitude, luxuriant trees and high oxygen content. It is known as "Tibet Jiangnan".

Linzhi Airport is the third civil aviation airport in Tibet. It started construction in October 2003 and was put into operation in September 1, 2006.
Visitors to Linzhi, after a period of time gradually adapt to the plateau climate, and then go to high altitude areas, reduce the trouble caused by oxygen, while along the road can appreciate the unique natural scenery and cultural landscape of the plateau.

At Linzhi Airport, there is a strange phenomenon. All planes can only take off and take off in the morning. Why?
It is understood that the river valley, where the Linzhi Airport is located, has low cloud weather, changeable wind direction and wind shear, which is often covered with fog and low visibility, affecting flight safety.

The wind direction is changeable, and the unstable wind speed is the most dangerous meteorological factor when the aircraft takes off and touchdown. It will cause the flight trajectory of the aircraft to deviate and make the aircraft lose stability. The driver's requirements are quite high. If the driver misjudged the mistake correctly, the consequences would be serious.

From 14 to 18 every day, the speed of the Linzhi Airport has increased greatly, which is two times that of the proper landing and landing speed.
Therefore, there are only flights in and out of the morning.
According to the statistics of meteorological data, the annual airworthiness time of the airport is only 100 days.
The unique plateau topography and bad weather conditions determine that Milin airport is the most difficult airport to fly in China.

So how does Linzhi Airport ensure flight safety?
If the airplane landing on the mainland airport is compared to a single log bridge, landing a plane at Plateau Airport is like acrobat walking tightrope.

In order to ensure the safe flight of the aircraft in the valley, the airport has set up a navigation station at the turning point of each route, and the wind profile radar is also installed to monitor the wind speed and wind direction in the surrounding area.

n flight, due to the narrow and tortuous path across the gorge, and beyond the normal flight standard, the aircraft's near ground automatic alarm device may trigger at any time.

Because of the complex terrain, the signals emitted by the navigation equipment will be covered and disturbed by the serious terrain. The flight space range is limited, and the Milin navigation station on the west side of the airport is only 11.2 kilometers from the actual control line of China and India.

The technical standards and psychological qualities of the generating units are facing severe challenges. Every air steering and every height change of the unit must be accurate.
Therefore, the captain is equipped with more than 10 years old pilots.
In addition, Linzhi area is located in the southeast, is one of the National Lightning disaster areas, the average annual thunderstorm days are more than 47.5 days, the airport is located in the valley, around the open, no other high-rise buildings.
Special geographical environment factors cause lightning accidents easily.
Therefore, all the building facilities of the airport are equipped with lightning protection facilities.

From Chengdu, we can arrive in Linzhi in two hours.
When the plane is flying over Linzhi and looking out from the window, you can feel the boundless charm of the snowy plateau, the continuous snow mountain, the holy glacier, the meandering rivers, the dense forest, the spring peach blossoms...

Out of the cabin, the blue sky, the white clouds, the warm sunshine, the refreshing air, the horizon, the snow mountain in the clouds, especially beautiful.
Everyone who got off the plane was excited and hurried to shoot the cell phone.
