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, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere.
At what layer do most airplanes fly at the top of?
The stratosphere is the layer of the Earth’s atmosphere where most aircraft reach their cruising altitude.
Can planes fly in mesosphere?
The mesosphere is difficult to study, so less is known about this layer of the atmosphere than other layers. … Weather balloons and other aircraft cannot fly high enough to reach the mesosphere. Satellites orbit above the mesosphere and cannot directly measure traits of this layer.
Do planes fly above the troposphere?
Although there are exceptions, most commercial jets fly at around 28,000 to 35,000 feet. … Commercial jets can certainly fly above or below the troposphere, but this layer of the atmosphere offers ideal flying conditions for several reasons.
Do planes fly in the ionosphere?
The ionosphere is particularly important to these flights. While they are over the Arctic, planes lose contact with most geosynchronous satellites and must rely on “old-fashioned” radio communications, a link that could be severed during a radio blackout.
What level of atmosphere do planes fly in?
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.
Can you breathe in the stratosphere?
The stratosphere is not a good place to be. First, the ozone in the stratosphere, which protects us from biologically destructive solar ultraviolet light, exists at such high levels that the air itself is toxic. Second, even this toxic air is much too thin for normal breathing.
What happens if a plane goes too high?
When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
Why does the temperature of mesosphere decrease with altitude?
Temperatures in the mesosphere decrease with altitude. Because there are few gas molecules in the mesosphere to absorb the Sun’s radiation, the heat source is the stratosphere below. The mesosphere is extremely cold, especially at its top, about -90°C (-130°F).
What is the hottest layer of the atmosphere?
The thermosphere is the hottest layer of the atmosphere.
Why planes do not fly over Tibet?
According Debapriyo, most commercial airlines avoid flying directly over the Himalayas. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”
Are planes checked before every flight?
Some people think that before taking off in an airplane the pilot simply has a casual glance at it. Perhaps he kicks the types, checks the fuel gauges to makes sure he has enough fuel, and then just departs. But this is very far from the case. All good pilots use pre-flight checklists before every flight.
What is the temperature at 35000 feet?
At 35,000 feet the air temperature is about -54C.
Do planes fly above the ozone layer?
Ozone is poisonous and, in high enough concentrations, can cause headaches, irritation to the respiratory system, and can harm lung function. Aircraft flying above the Tropopause may therefore be flying through air with high concentrations of Ozone.
Which is the coldest layer?
Mesosphere, altitude and temperature characteristics
The top of the mesosphere is the coldest area of the Earth’s atmosphere because temperature may locally decrease to as low as 100 K (-173°C).
What layer do we live in?
The troposphere is the lowest layer of the atmosphere. This is the layer where we live and where weather happens.
