Why are you looking out on the plane?

Hello, most civil aviation planes fly at high altitude. The high altitude here refers to the space with an altitude of 7000-12000 m. This height is basically above the clouds, so basically the outside is boundless. Of course, the height of the clouds is not fixed, sometimes hundreds of meters, sometimes thousands of meters in sunny weather, and the aircraft flying into the general clouds will not be greatly affected, only thunderstorms and frozen areas that threaten flight safety have a greater impact.
