Commercial aircraft routinely fly through the lower edges of the ozone layer. The systems that provide a breathable atmosphere for the passengers, includes a catalyst filter to destroy / reduce the amount of ozone in the air they pump into the cabin.
Do planes damage the ozone layer?
1 Answer. Yes, high flying jets can damage the ozone layer, but the consensus of opinion is that at present this damage is trivial and nothing to worry about. … The jets need to fly at altitudes between about 30,000 feet and 45,000 feet to cause ozone damage.
Does Aeroplane fly above 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 layer of the 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.
Why do planes do not fly over the Pacific?
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.
Do planes pollute more than cars?
A single flight produces three tons of carbon dioxide per passenger, but the amount goes up dramatically if the plane is nearly empty. … Driving a car solo has the same basic climate impact as taking an 80-percent-full plane flight a similar distance, the study said. If the plane is full, it beats the car.
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 layer is ozone?
Additional Information. Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth’s surface (see the figure below). Ozone is a molecule that contains three oxygen atoms.
Do planes fly in the troposphere?
The atmosphere is divided up into five main layers but commercial aircraft fly in the bottom two layers — the troposphere, which sits closest to the surface, and the stratosphere, which sits just above it. As you climb up into the troposphere, the air pressure, temperature and air density all decrease.
What layer do we live in?
The Troposphere: Beginning at the surface of Earth, the troposphere extends to around seven miles up. This is the layer we live in and contains most of what we consider to be “the atmosphere”, including the air we breathe and nearly all of the weather and clouds we see.
Can planes fly in the mesosphere?
The layer above the mesosphere is called the thermosphere. The mesosphere starts at 50 km (31 miles) above Earth’s surface and goes up to 85 km (53 miles) high. … Weather balloons and jet planes cannot fly high enough to reach the mesosphere. The orbits of satellites are above the mesosphere.
What is the hottest layer of the atmosphere?
Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere. Above 124 mi (200 km), the temperature becomes independent of altitude.
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).
Do planes fly over Everest?
Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. … 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.”
Why do pilots say heavy?
When a pilot uses the phrase “heavy,” he is reminding ATC that his aircraft is large and requires more separation between it and the aircraft following.
Is it safe to fly over the ocean?
Yes it can. The cargo holds are designed with fire extuingishers, as are the engines and the cabin. There are multiple fire extinguishers inside the aircraft that can be operated by the cabin crew or even the pilots.
