Why do jet airplanes fly at high altitudes on the order of 30000 feet or greater )?

The biggest reason for this altitude lies with fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed.

Why do jet planes fly at 30000 feet?

Most often, commercial airplanes fly anywhere between 30,000 and 42,000 feet in the air, which equals five to seven miles high. Why? The main reason is fuel efficiency. Put simply, airplanes use less fuel in higher altitudes where the air is thinner, increasing the efficiency and saving them money at the same time.

Why can an aircraft fly faster at 35000 feet than at 12000 feet?

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.

Why do commercial 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. … Also, oxygen starts to become scarce, making it difficult for fuel engine systems to work.

Why do planes fly at 40000 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. … Many business jets can fly higher, routinely cruising in the high 40,000s. The maximum altitude for many business jets is 51,000 feet.

What happens if an airplane 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.” …

What is the highest a plane has ever flown?

Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 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.

Do planes fly over the ocean?

Although there are exceptions, most commercial airlines don’t fly directly over the Pacific Ocean for routes connecting the United States to Asia. Instead, they choose “curved” routes that hug bodies of land.

Do you travel faster the higher up you are?

Yes, time goes faster the farther away you are from the earth’s surface compared to the time on the surface of the earth. This effect is known as “gravitational time dilation”. … Time itself is slowing down and speeding up because of the relativistic way in which mass warps space and time.

Why do private jets fly at higher altitudes?

One of the reasons private jets fly at a higher altitude than commercial jets is to avoid heavy air traffic. … Private jets lack the high-tech sensors and controls of commercial jets, so pilots operating them typically fly at a higher altitude where there’s less traffic.

Why can private jets fly higher than commercial?

When it comes to private jet cruising altitude, private jets indeed fly higher than commercial jets. The two main reasons why they fly higher is because there’s less traffic at higher altitudes, which means they aren’t competing for the same airspace as other airplanes.

How long does it take for a plane to crash from 35 000 feet?

This was the start of the descent that would see the Airbus A330 drop 38,000 feet in just three minutes at a rate of over 10,000 feet a minute and at a speed of 124mph.

What is the temperature outside an airplane at 30 000 feet?

A: The standard temperature for 30,000 feet is -44.5C or -48F (Source: meteorologytraining.tpub.com/14269/css/14269_75.htm). All materials used in airplanes are designed and tested to withstand temperature extremes.

What’s the highest commercial planes 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.

Can you breathe at 40000 feet?

Somewhere between 30,000 and 40,000 feet the pressure around you becomes far too low to push those oxygen molecules across the membranes in your lungs, and you get hypoxic (altitude sickness). If you try to breathe 100 percent oxygen above 40,000 feet for very long without a special type of mask, you’ll die.
