Because it saves fuel. The less dense the air, the easier the plane moves through it. The engines are also more efficient.

Why do planes fly high?

Planes fly at high altitudes because the thinner air reduces air resistance, allowing the aircraft to fly more efficiently. Flying at high altitudes also provides smoother air currents, less turbulence, and shorter flight times due to the ability to take advantage of jet streams. Additionally, being at a higher altitude allows planes to avoid obstacles on the ground and have more flexibility in choosing their flight path.


Jet planes fly in this part of the atmosphere?

Jet planes fly in the stratosphere, which is the second layer of Earth's atmosphere. This layer provides a stable environment for jet propulsion and allows for efficient flying at high altitudes.


Why do jet planes normally fly in the statosphere?

Jet planes normally fly in the stratosphere because the air is thinner at higher altitudes, which reduces drag on the aircraft and allows it to operate more efficiently. Additionally, flying at this altitude helps to avoid bad weather conditions and turbulence commonly found in the lower atmosphere.


What can you infer about the height jet airplanes fly based on the fact that their contrails form cirrus clouds?

The fact that jet airplanes' contrails form cirrus clouds suggests that they fly at altitudes where the temperature and humidity are conducive to contrail formation, typically above 20,000 feet. This indicates that jet airplanes generally fly at high altitudes, where the air is colder and less dense, allowing contrails to persist and spread out into cirrus clouds.


Why did david hempleman-adams needed an oxygen mask to fly at high altitude?

David Hempleman-Adams needed an oxygen mask to fly at high altitudes because the air is thinner at higher altitudes, which means there is less oxygen available for breathing. Flying at high altitudes without supplemental oxygen can result in hypoxia, which can impair cognitive and physical function. An oxygen mask helps to ensure that the pilot receives enough oxygen to maintain safe levels in the bloodstream.

Can bulldogs fly on planes?

No, bulldogs cannot fly on planes due to their brachycephalic (flat-faced) anatomy, which can cause breathing difficulties at high altitudes. Airlines have restrictions on flying certain breeds for their safety.

Why do fighter planes fly at great height?

At high altitudes the atmosphere is less dense that at lower altitudes. This means that planes flying higher experience less drag (friction) than those lower down, so that means they can go faster.

Why do jet airplanes fly at high altitudes?

Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.


Can missiles shoot down planes if having trouble detecting?

No. Missiles gotta be able to detect planes in the radar in order get a lock on because missiles need to get a lock on to shoot down planes but planes fly in really high altitudes, this makes it even more difficult to detect planes on radar.


How high can a ladybird fly?

Ladybugs can fly at very high altitudes without any problems. This beautiful insect can also travel great distances and travel hundreds of miles at a time.


At what altitudes do jet planes fly?

It really depends on what the size of the jets. The Airlines fly from 32,000 to 38,000 feet.Normal Jet Planes fly at about 30,000 feetMilitary Jet planes fly anywhere from 100 feet all the way up to 80,000 (Some do go higher but those are for special occasions)


Why only officers can fly military planes?

Military planes can only be flied by the military officers because the officers are well-trained and highly qualified to fly the military aircrafts. The officers are trained in high altitudes and in many different regions which helps them in flying the aircraft in bad whether or whatever the condition is.


Why do planes fly certain altitudes?

Because they have winglets which cause them to release farts. These farts eventually cause the plane to explode.


How high do planes fly at?

Normal planes go at 40,500 feet from ground.
