Why do long distance aircraft choose to fly in?
Due to this temperature stratification, there is little convection in the stratosphere, and so the layers of air is quite stable. That is why, aircraft fly easier through the stratosphere to avoid the turbulence of friction and drag.
Why do airplanes not fly in the troposphere?
The layer that exists between the troposphere and the stratosphere is termed as the tropopause. Also, large passenger planes cannot fly at higher levels because the air is too thin above that and the oxygen level decreases.
Why do you think airplanes don’t fly high in the stratosphere?
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 there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
