I think the maximum flight level for commercial passenger airliners is 41,000 feet.
That's 12.5 kilometers above sea level.

The altitude above the ground depends on how high the ground is.

The highest ground on earth is the peak of Mt. Everest, about 8.9 km above sea level.
So the maximum flight level for a passenger jet is about 3.6 km higher than the highest
point on the ground.

Jet airplanes typically fly at cruising altitudes ranging from 30,000 to 40,000 feet above ground level, which is approximately 9,000 to 12,000 meters.

Which layer of the atmosphere is the highest that in airplane can fly?

The layer of the atmosphere where airplanes can generally fly is the stratosphere, which extends from about 10 to 50 kilometers above the Earth's surface. Most commercial airplanes fly in the lower part of the stratosphere, around 10-15 kilometers above the ground, where the air is thinner and there is less turbulence.

What part of the atmosphere do airplanes fly?

Airplanes fly in the troposphere, which is the lowest layer of Earth's atmosphere. This layer extends from the Earth's surface up to an average altitude of about 11 kilometers (7 miles).


Why don't airplanes fly in the troposphere?

Airplanes dont fly in the stratosphere because they produce too much sound. This may cause noise pollution and stress among people who are on the ground. So they dont fly in the Troposphere.


What layer do the airplane fly?

Airplanes typically fly in the troposphere, which is the lowest layer of Earth's atmosphere. This layer extends from the surface up to around 12 kilometers (7 miles) in altitude.

How much kilometers can an airplane fly?

It depends on the fuel capacity. Some airplanes can refuel during flight so conceivably, they can fly until the engines need maintenance. Current aircraft can fly up to 8,000 miles or about 14-15,000 kilometers.


Why does a person fly in airplanes?

Because people are not able to fly without a airplanes.


In which layer the aircrafts are allowed to fly?

Small airplanes like Cessna can fly close to ground. This is because they dont cause much noise. But big airplanes like Boeing and other passenger planes are allowed to fly only in the stratosphere. They cause much noise.
