Frequent question: Why do aircraft 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 do planes fly between 35000 and 42000 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 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.

Why do pilots prefer to fly at 36000 feet?

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. Less wind resistance, more power, less effort, so to speak. Spending less on fuel is also great for airlines, for obvious reasons.

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.

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.

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.” …

Can a helicopter fly across the Atlantic?

A helicopter can fly across the Atlantic – and this has been achieved several times. The first transatlantic helicopter flight took place in 1952. The first non-stop transatlantic helicopter flight took place in 1967.

Why don’t we fly over the North Pole?

North Pole FAA Flight Requirements

Adding to the problems are the fact that being so near the North Pole can interfere with navigation systems that rely on magnetism. Planes flying in the North Pole, thus, need to have equipment that can compensate for this as best as possible.

Do you fly faster against Earth Rotation?

At the equator, the Earth spins about twice as fast as a commercial jet can fly. That rate slows the closer you get to the poles, but regardless, it’s always going to be faster than a plane.

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.

Can you see a plane at 30000 feet?

Here is the theoretical distance you can see from a plane at different altitudes, given perfect weather conditions: at 1000 feet: 38.7 Miles (62km) … at 30,000 feet: 211.3 miles (340 km) at 39,000 feet: 235 miles (391 km)

Why do jetliners 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.

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.

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.

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.
