Question

why do airpcrafts fly in the stratosphere layer of the atmosphere?​

Answer 1

Explanation:

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry air and contains little water vapor. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere

Answer 2

Answer:

the lower layer of stratosphere has virtual absence of water vapour and has constant temperature conditions therefore it is suitable for flying aircrafts
