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 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.

Can commercial planes fly at 50000 feet?

Most US military aircraft can exceed 50,000 feet, if they really really try. Again, the limits are classified. Most commercial jetliners cruise somewhere between 30,000 and 45,000 feet above mean sea level.

Why do planes not fly 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 commercial planes 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 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.” …

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.

How cold is it at 40000 feet?

After all, commercial airplanes can cruise at an altitude of nearly 40,000 feet, where temperatures hover around -70 degrees Fahrenheit.

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 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.

How do fighter pilots pee?

Piddle Packs are small bags male fighter pilots use to pee while in flight. Piddle-packs are the ultimate long road trip solution. They are specially shaped bags with absorbent beads in them.

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.

How fast do commercial planes fly?

Most commercial aircraft typically fly at around 460-575 mph, or 740-930 km/h, according to Flight Deck Friend. But private jet speed can vary depending on a variety of factors, such as the weight onboard and the weather conditions.

Why do airplane wings flex?

Allowing the wings to flex improves aerodynamic stability. The aircraft is more streamlined and experiences less drag. It helps provide a smoother ride for passengers and minimize turbulence. The 787 fly-by-wire technology also helps here to automatically raise or lower the wing trailing edge during the cruise.
