# You asked: Can planes fly at 45000 feet?

Contents

Question: What is the highest altitude an airplane can fly? 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.

## Is there turbulence at 45000 feet?

A: Most airliners are limited to 45,000 feet or less. Q: Is there any altitude where there would be no turbulence? — Bill B. A: Yes, very high altitude, above 50,000 feet, where there is very little air, has little or no turbulence.

## Can a plane fly 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.

## Can planes fly at 40 000 feet?

Modern airliners are usually built with the ability to function when flying over 40,000 feet. … The service ceiling is the maximum density altitude an airliner can reach according to its design. However, travelers are more likely find themselves in the air at a cruising altitude of around 35,000 feet.

## What is the highest height a plane can 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.

## 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 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.

## Is there turbulence at 40000 feet?

Turbulence on private jets

Private jets fly higher than commercial jets – Boeing and Airbus fly on average at 35,000 – 40,000 feet. … However, the reduced weight of private jets can mean the same amount of turbulence would feel worse than if you were on a 747 jet.

## 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.

## How high can a private jet fly?

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 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.

## How high can a 747 fly?

A Boeing 747 has a cross height of 35,105 ft, while the Embraer climbs 190 to 39,370 ft. The Airbus A380 can even fly at 43,097 ft. At the bottom of this page, you will find an overview of the cruising altitudes of the most common aircraft at Schiphol.

## Why do private jets fly so high?

Private jets can fly as high as 51,000 feet. These altitudes are reserved for the larger aircraft. This is because on a short journey it is not efficient to spend significant time climbing to a high altitude, only to descend shortly after reaching the maximum altitude.

## What happens if a jet 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 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.

## 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.
