What sphere do airplanes 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.
Do planes fly in the ozone layer?
Planes fly in the second layer of the atmosphere called the stratosphere. The stratosphere is the second layer of the atmosphere and the one where the ozone layer is formed and where the planes fly in. The temperatures in the stratosphere are inverse to those in the troposphere, meaning they rise with altitude.
Which layers of the atmosphere do most planes fly through?
Complete Step by Step Answer: Stratosphere is the layer of the atmosphere where planes usually fly. It usually extends up to 50 km above the ground. Most of the jet aircraft fly in the lower layer of the stratosphere, to avoid any turbulence, although thunderstorms do penetrate the stratosphere.
Do planes only fly in the troposphere?
Although there are exceptions, most commercial jets fly at around 28,000 to 35,000 feet. Being that Earth's troposphere is between 23,000 and 65,000 feet — depending on the season and latitude, at least — this means that commercial jets are almost always within the troposphere.
What can be found in the ionosphere?
The ionosphere is a shell of electrons and electrically charged atoms and molecules that surrounds the Earth, stretching from a height of about 50 km (30 mi) to more than 1,000 km (600 mi). It exists primarily due to ultraviolet radiation from the Sun.

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."
What's the highest a plane can fly?
Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a 'service ceiling. ' For example, for the double-decker Airbus A380 'superjumbo' quadjet, this ceiling is 43,000 feet. Meanwhile, for the Boeing 787-8 and -9 'Dreamliner,' it is 43,100 feet.
Do planes fly above the atmosphere?
The average commercial passenger jet aircraft cruises at an altitude between 30,000 and 42,000 feet (ft) (9,000 – 13,000 meters). This means that aeroplanes usually fly between 5 to 7 miles up in the air.
Why is the ionosphere important?
The Ionosphere is part of Earth's upper atmosphere, between 80 and about 600 km where Extreme UltraViolet (EUV) and x-ray solar radiation ionizes the atoms and molecules thus creating a layer of electrons. the ionosphere is important because it reflects and modifies radio waves used for communication and navigation.
Where is the ionosphere located?
Located within the thermosphere, the ionosphere is made of electrically charged gas particles (ionized). The ionosphere extends from 37 to 190 miles (60-300 km) above the earth's surface.
Which phenomenon can be seen only in the ionosphere?
The colorful curtains of light, known as the aurora borealis and aurora australis, respectively, hang about 620 miles (1,000 km) above the Earth's surface. The auroras glow green-yellow when ions strike oxygen particles in the lower ionosphere.
Can planes fly in the mesosphere?
The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Weather balloons and other aircraft cannot fly high enough to reach the mesosphere.
What layer does a helicopter fly?
Helicopters and light aircraft typically fly in the troposphere.
What are 3 facts about the ionosphere?
10 Things to Know About the Ionosphere
Why ionosphere is so called?
The ionosphere is a very active part of the atmosphere, and it grows and shrinks depending on the energy it absorbs from the Sun. The name ionosphere comes from the fact that gases in these layers are excited by solar radiation to form ions, which have an electrical charge.
Does the ionosphere affect radio?
The ionosphere is a particularly important region with regards to radio signal propagation and radio communications in general. While the ions give the ionosphere its name, but it is the free electrons that affect the radio waves and radio communications.
Why do planes fly at 38000 feet?
Due to lower resistance at higher altitudes, commercial airplanes can keep moving forward with minimal fuel expenditure. Commercial airplanes typically fly between 32,000 feet and 38,000 feet, with the sweet spot being approximately 35,000 feet, which is popularly referred to as cruising altitude.
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 window breaks on an airplane?
Basically, the air pressure inside the cabin is higher than it is outside of the plane to enable the people onboard to breathe normally. That's why, if a window happens to break, the air inside would escape at high speeds, taking small objects like phones or magazines (or sometimes larger things, like people) with it.
Why do planes not get struck by lightning?
The fuel tanks in the wings are not exposed to any lightning sparks because the surrounding metal, structural joints, access doors, vents, and fuel filler caps can withstand any burning from a bolt of lightning, which temperature can reach up to 30,000C.
What happens if a plane flies into a tornado?
Flying through a tornado could destroy an airplane; pilots avoid all thunderstorms -- particularly those producing tornadoes -- by a wide margin. Cumulus clouds are caused by rising warm air; when an airplane flies into the rising current of air, it is bumpy.
Why do planes not fly directly over the Pacific Ocean?
The primary reason airplanes don't fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn't flat. Rather, it's spherical. As a result, straight routes don't offer the shortest distance between two locations.
What is the slowest plane?
The slowest jet aircraft is the Polish-made PZL M-15 "Belphegor", a single-engined crop-dusting plane that made its first flight on 20 May 1973. The Belphegor was a biplane weighed down with two huge pesticide tanks that had a top speed of just 200 km/h (120 mph).
Can a passenger plane stop in the air?
No a plane doesn't stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). What it can do is simply turn around or go over/under the obstruction. VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.
Do planes fly above rain?
Rain doesn't usually affect a flight much. Combining with hefty winds causes extra challenges to flight planning. Heavy rain could affect visibility, but planes generally fly on instruments anyway, so this will not be an issue in itself.
Can a normal person land a plane?
Short answer: maybe, if he or she had plenty of help from air-traffic control and were good at multitasking. In movies, normal people are often put in situations where they have to land a plane.
How do satellites survive the thermosphere?
Many satellites orbit within the thermosphere and changes in the density of (the very, very thin) air at orbital altitudes, brought on by heating and expansion of the thermosphere, generates a drag force on satellites. These waves and tides help move energy around within the atmosphere, including the thermosphere.
How does the ionosphere work?
The ionized part of the Earth's atmosphere is known as the ionosphere. Ultraviolet light from the sun collides with atoms in this region knocking electrons loose. This creates ions, or atoms with missing electrons. This process also works in reverse for radio waves produced on the earth.
Is the ionosphere hot or cold?
Due to fluxes in solar radiation, temperatures in the ionosphere vary from 200 Kelvin (or -99 degrees Fahrenheit) to 500K (or 440 degrees Fahrenheit).
Where does the ionosphere start?
The ionosphere begins at a height of about 50 km (30 miles) above the surface, but it is most distinct and important above 80 km (50 miles).
What is the altitude of the ionosphere?
The ionosphere is an abundant layer of electrons and ionized atoms and molecules that stretches from about 48 kilometers (30 miles) above the surface to the edge of space at about 965 km (600 mi), overlapping into the mesosphere and thermosphere.
How does the ionosphere enable us to listen to the radio?
Radio antennas "listen" for radio signals generated by the ionosphere itself, radar systems bounce signals of the different layers, and pairs of transmitters and receivers shoot signals through the ionosphere to determine how much those signals are dampened or redirected.
Is the geosphere?
The geosphere is the earth itself: the rocks, minerals, and landforms of the surface and interior. Below the crust - which varies in depth from about 5 km beneath the ocean floor to up to 70 km below the land surface, temperatures are high enough for deformation and a paste-like flow of elements.
Who discovered the ionosphere?

|1909||Marconi awarded Nobel Prize|
|1924||Edward Appleton and others develop the ionosonde and begin ground-based soundings; prove existence of ionosphere|
|1925||Appleton discovers second layer (the F region)|
What happens in the Thermopause?
The thermopause is the atmospheric boundary of Earth's energy system, located at the top of the thermosphere. As a lower boundary for the exosphere this boundary is also called the exobase. The exact altitude varies by the energy inputs of location, time of day, solar flux, season, etc.
What is tropopause in aviation?
The tropopause is the upper limit of the troposphere and therefore constitutes the boundary between it and the Stratosphere. The airflow effect may “draw” stratospheric air from above and enter the warm air troposphere by way of the jet stream.
