Why planes don t fly over 40,000 feet?

Why planes don t fly over 40,000 feet? A higher elevation will require a longer climb, meaning the aircraft will burn more fuel in order to reach its cruising altitude. Additionally, 35,000 feet gives more time for airline crew to address any unexpected mid-flight incidents.

What altitude can you not breathe?

It refers to altitudes above a certain point where the amount of oxygen is insufficient to sustain human life for an extended time span. This point is generally tagged as 8,000 m (26,000 ft, less than 356 millibars of atmospheric pressure).

How high can military planes fly?

The speed record is also held by an SR-71, at 2,193 mph. This is not as high or as fast as the airplane can fly, however, it's absolute speed and altitude limits are classified. Most US military aircraft can exceed 50,000 feet, if they really really try. Again, the limits are classified.

Why do planes fly better in cold air?

But icing aside, cold air can help a plane take off and fly more efficiently. So why do planes perform better in cold weather? Simply, colder air is denser than warmer air, which contributes to engine performance and air lift.

Can a plane fly higher than Mount Everest?

If you've traveled by air, you know that sometimes it inspires frustration and questions. Planes cruise almost 7 miles high in the sky. That's 7,000 feet higher than Mount Everest. A major reason for flying at that altitude is money.

How high can you fly without oxygen?

For Part 91 General Aviation operations the required flight crew must use supplemental oxygen for any portion of the flight that exceeds 30 minutes above a cabin pressure altitude of 12,500 feet mean sea level (MSL) up to and including 14,000 feet (MSL).

Is it safe to fly at 41000 feet?

The sweet spot for modern airliners is between 35,000 and 42,000 feet, where the plane's engines are most efficient. The way the wings are designed is also unsuitable for thin-air flight as they would not be able to create enough lift. Planes cannot just keep going up and up - at some point, it will stall.

What happens if a plane flies at 60000 feet?

Flying beyond the altitude of 60,000 feet entails the risks of structural failure, physiological hazards, and decreased operational efficiency. Commercial airliners are specifically engineered for lower altitudes, and exceeding these prescribed limits may also give rise to aerodynamic complications.

What happens if a plane flies too high?

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.

Can a plane fly at 50000 ft?

Many business jets can travel even higher, at 50,000 feet, due to having large engines for the small size of the aircraft. The lighter weight enables these aircraft to climb higher more easily than larger jets with many passengers and materials.

What happens if a plane goes 50000 feet?

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.

Can a plane fly 100k feet?

A: No commercial or business airplane flying today can exceed 100,000 feet. Special rocket-powered airplanes can fly over 100,000 feet to gather data, but they are specially designed for it.

Is there turbulence at 40000 feet?

Severe turbulence, he added, is “quite rare — only 0.1% of the atmosphere at 40,000 feet has severe turbulence in it, so if you're on a plane it's very unlikely that your plane will hit that 0.1%.” “However, given the number of planes in the skies, one of them will.

Why do private jets fly higher?

Commercial jets, however, have more sensors and control measures to prevent midair collisions, meaning they generally aren't affected by 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.
