Why can't the plane get into Kunlun Mountain?

The reasons include high altitude hypoxia, low pressure and bad weather.

1, plateau hypoxia: Kunlun Mountain is very high above sea level. With the increase of altitude, the oxygen content in the air will gradually decrease. High altitude hypoxia will affect the engine performance of aircraft, which may lead to engine flameout.

2. Low pressure: At high altitude, the atmospheric pressure will decrease with the elevation. Low air pressure will have an impact on the flight performance of the aircraft, which may lead to the aircraft losing control.

3. Bad weather: The weather in Kunlun Mountain area is bad, and extreme weather such as strong wind and heavy snow often occurs. These weather conditions will pose a threat to the flight safety of aircraft.
