Why didn't the plane fly over Tibet? Can you talk about it?

Traffic is becoming more and more convenient, and many people like to travel by plane, which can save a lot of time. In our subconscious, planes can fly all over the world, as long as there is an airport, but there is a place in our country where planes can't fly. Do you know where it is?

When you open the route map of the flight, you will be surprised to find that none of the routes pass through Tibet. This is because of the special geographical environment in Tibet. Tibet has the highest altitude in the world, the Qinghai-Tibet Plateau, with an average elevation of more than 4,000 meters, which is called the roof of the world. The Qinghai-Tibet Plateau has always been one of the biggest obstacles to world aviation. 1 1955 Dangxiong Airport, the first airport in Tibet, has been demolished. 1965 Lhasa Gongga International Airport is a modern airport, so you can fly to Tibet now, but most flights will still avoid Tibet. The first difficulty in crossing Tibet is Tibet. The altitude of the military is four kilometers. Once the plane encounters an emergency, such as engine decompression or engine failure, the flying height of the plane needs to be reduced to 3048, which means that the plane will hit a hillside, so it is difficult to ensure the safety of passengers in an emergency unless it can land at an airport in Tibet. But once the plane can't get to the airport, it means that the plane will crash.

Everyone has seen Captain China, which is based on the real event of 20 18. On May 2018 14, Sichuan Airlines 3U8633 flew from Chongqing to Lhasa. During the 9800-meter cruise, the right inner windshield cracked, and then it applied for returning. Later, the windshield broke and the crew immediately lowered the flying height. Fortunately, he finally returned smoothly and no one died. Most planes will avoid Tibet for fear of an emergency when flying over Tibet. Although Tibet accounts for 1/8 of the country's total area, its permanent population is only 55.9 million, because there are many mountains below Tibet, and when the wind blows. When it is dry, an airflow will form over the mountain. If the plane is over the mountain at this time, it will bump because of this airflow. When the temperature is below MINUS 40 degrees Celsius, jet fuel will be frozen, but it can still fly for a short time. But the plane can't fly for a long time at this temperature. The temperature in Tibet reaches MINUS 40 degrees Celsius, so the plane will avoid it. Therefore, for security reasons, the plane will not choose to fly over Tibet. Although our traffic is very developed, there are still some areas where the environment is not good, so we can't go if we want, but we can leave if we want.
