Solution

Stratosphere is considered the most stable layer of atmosphere.

Explanation:

The stratosphere lies above the troposphere and extends up to around 50 km. It is relatively calm and stable because it has no clouds or weather phenomena like the troposphere. Temperature in the stratosphere increases slowly with altitude due to absorption of ultraviolet radiation by the ozone layer, which adds to its stability. These conditions make it the most stable and calm layer of the atmosphere, ideal for flying jet planes.
