Quick Answer: Why do commercial jets fly so high?

The reason aeroplanes fly so high is due to improved fuel efficiency. A jet engine operates more efficiently at higher altitude where the air is much thinner, allowing an aircraft to travel faster whilst at the same time, burning less fuel.

Why do planes fly at 35000 feet?

A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Commercial airplanes can climb to 42,000 feet, but going beyond that can be precarious, as the air starts to become too thin for optimum flight of the airplane.

Why don t commercial jets fly higher?

Carriers avoid a massive amount of turbulence that would occur at lower levels. Along with this, most thunderstorms, severe weather incidents and birds can be avoided while above 35,000 feet. Also, the air is thin enough to reduce the aircraft’s drag, increasing its fuel efficiency.

Do private jets fly higher than commercial airlines?

Commercial flights typically fly at an average altitude of 35,000 feet. Private jets, on the other hand, reach much greater heights, usually at 41,000 feet. Others even reach 45,000 feet.

How high can commercial planes fly?

FAQ » General FAQs » How high do commercial planes fly? The approved maximum altitude for most commercial aircraft is 42,000 feet.

Can a plane fly over Mount Everest?

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.

Can a plane fly at 60000 feet?

There are some higher limits though outside current commercial aircraft. Concorde (of course, no longer operational) was rated to fly up to 60,000 feet. And many private jets operate up to around 45,000 to 51,000 feet. And if you introduce military jets, the SR71 holds the record (for normal flight) at 85,000 feet.

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.

Why do planes fly at 39000 feet?

1. Many flights are not as full as they were, so they are lighter and can fly at higher altitudes, which are more fuel-efficient. … Most airliners have maximum certified altitudes of 39,000 to 41,000 feet; a few can go higher but usually do not. Many business jets can fly higher, routinely cruising in the high 40,000s.

Are private jets faster?

TLDR – Private jets typically travel faster compared to commercial jets because they fly at higher altitudes. The average private jet is also smaller compared to most commercial jets, which allows for faster speeds.

Do jets go higher than planes?

A private jet can fly at a height of up to 45 000 ft, though most cruise at 41 000 ft. This is generally higher than an airline flight and allows for a more direct route – out of the most congested area of the sky. A private jet pilot will choose the optimum cruising altitude depending on the distance of the journey.

Why are military jets louder than commercial?

Defence Aircraft Noise

Commercial aircraft tend to use high-bypass, turbo-fan engines which are suitable only for subsonic flight (flying slower than the speed of sound or 1,225km/h). … In contrast, military fighter jets use low-bypass, turbo-jet engines which are generally noisier than commercial aircraft engines.

Are private jets safer than commercials?

But statistically, and based on direct comparisons each year, it’s theoretically still safer to fly commercial. … The clear difference between flying commercial and flying private is less associated with safety, and instead on how flying private jets is worse for the planet than taking a scheduled passenger flight.

What happens if a plane flies 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.” …

Do planes fly above clouds?

One reason that planes cruise above the clouds is so they can fly fast. The higher airplanes climb, the thinner the air gets, and the more efficiently they can fly because of less resistance in the atmosphere, according to Ryan Jorgenson, an aviation data analyst.

Why do planes fly faster at higher altitudes?

The higher the better

One of the central reasons behind aircraft altitude is that, as the air gets thinner with every foot climbed, planes can travel more easily and therefore move faster and burn less fuel, saving money.
