Awesome! Why Do Airplanes Not Fly High In The Stratosphere
As an aircraft climbs the atmospheric pressure decreases and as a result the drag DECREASES. Sometimes really strong thunderstorm tops may poke into the stratosphere and aircraft cannot get over them and need to deviate around them.

There are exceptions to this however.
Why do airplanes not fly high in the stratosphere. Indeed most commercial planes hit their cruising altitudes in the lower stratosphere. Why do jet airplanes often fly in the stratosphere. That higher speed is combined with a decrease of density.
Commercial aircraft typically prefer to. This may cause noise pollution and stress among people who are on the ground. Yes you lose density yes you lose a bit of lift because of that and yes you will need to fly faster in order to generate that lift.
Helicopters and light aircraft typically fly in the troposphere. Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. The lower stratosphere can support some of the higher end spy planes such as the SR-71 spy plane but commercial airplanes are not permitted to fly in the stratosphere.
Flying to higher altitudes would require pilots to wear functional oxygen masks to avoid losing consciousness. As has probably been said the atmosphear density drops with altitude as does the temperature an aircraft with air breathing engines willrequire the correct air to fuel ratio in the combustion chamber in order to develop the required thrust to keep the plane aloft at higher altitudes ther is a significant drop in the oxegen content towel the engines alight how ever ther is also the risk of. Upon reading that you might be wondering why commercial jets dont fly in higher levels of Earths atmosphere like the stratosphere or mesosphere.

At the top of the tropospherestart of the stratosphere temperature stops decreasing as altitude increases which is why planes fly there specifically. Most commercial airplanes have a certified maximum altitude of about 40000 to 45000 feet. Airplanes dont fly any higher than the stratosphere and into the mesosphere or beyond for three main reasons.
Light aircrafts are unable to operate at higher altitudes because they lack pressurized cabins. High speeds may be attained with engines and aircraft specially designed for flight at high altitudes and much valuable information about engine development is obtained from a close study of the problems of such flights. Regardless of its certified maximum altitude if an airplane flies too high it may fail in one or more ways.
THE SPECIALLY INSULATED COCKPIT of the Bristol 138A monoplane designed for flying in the stratosphere. As air density is so low it is very challenging for an airplanes wings to produce adequate lift and adequate thrust also cannot be generated. The air in the stratosphere is very thin and not enough air pressure is available to provide the needed lift to support the airplane.
The main reason airplanes fly in the stratosphere is because this is where the least amount of turbulence is found. The aircraft could not care less though. At around 45000 feet most commercial jets would burst open becuase of this effect.
While most commercial airplanes fly at 30000 to 36000 feet their respective certified maximum altitude is typically slighter higher. In addition because the stratosphere is very dry there are fewer clouds in this layer making for. Why do airplanes not fly high in the stratosphere.
Airplanes dont fly in the stratosphere because they produce too much sound. After all if air gets thinner at higher altitudes conventional wisdom may lead you to believe that flying in the stratosphere would provide even greater fuel efficiency benefits than flying in the troposphere. The stratosphere combines largely cloud-free skies with limited turbulence making it attractive to airline pilots.
By flying above the troposphere in the tropopause or the stratosphere airplanes tend to avoid most of the bad weather and turbulence associated with it. Why do planes do not fly over the Pacific. So they dont fly in.
Why do jet airplanes often fly in the stratosphere. This is because when the plane is parked on the runway its already moving at a very high speed almost 1000 mph due to the rotation of the Earth. This is because the Himalayas have mountains higher than 20000 feet including Mt Everest standing at 29035 feet.
Why do passenger planes fly so high. Similarly a plane cannot hover in the sky and land at a different destination. In fact the air resistance in the stratosphere is about half of the resistance found on the ground which means the plane can hold airspeed at lower power settings so not as much fuel is used.
Therefore they stay within a range of about 10000 feet. When stratospheric clouds do form theyre sometimes created by the mixing of ice with volcanic dust. As others have shown the difference in distance is negligible and the efficiency gains are well worth it.
As an aircraft climbs the atmospheric pressure decreases and as a result the drag DECREASES. Flying so high also means that aircraft are able to avoid other airborne traffic such as light aircraft or helicopters which fly lower as well as. Then when it takes off its final speed is the sum of two different speeds the speed that it gained by firing.
The real answer why jets and other aircraft often or even always fly at higher altitudes for airliners in the 3040000 foot altitude has to do with their efficiency. As it goes higher the pressure outside the aircraft decreses putting more pressure on the cabin. Why don airplanes fly in the stratosphere.
This is because in higher altitudes such as those found in the stratosphere there is less air resistance. However most commercial airplanes can. The real answer why jets and other aircraft often or even always fly at higher altitudes for airliners in the 3040000 foot altitude has to do with their efficiency.
