# Quick Answer: How cold is it outside an airplane?

Contents

The Troposphere is closest to the surface of the earth, and as you climb into it, on average, the temperature decreases by roughly 3.6°F for every 1,000 feet. This means that at cruising altitude of 37,000 feet, the outside air temperature could be minus 76°F.

## What is the temperature outside an airplane?

At 35,000 ft. (11,000 m), the typical altitude of a commercial jet, the air pressure drops to less than a quarter of its value at sea level, and the outside temperature drops below negative 60 degrees Fahrenheit (negative 51 degrees Celsius), according to The Engineering Toolbox.

## 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.

## How cold is it at 39 000 feet in the air?

Very. At 38,000 feet — the cruising altitude of the Hawaiian Airlines flight that the FBI says the 15-year-old took Sunday — the outside air temperature is about minus 85 degrees. The air is so thin that a person will pass out because the brain is starved of oxygen.

## Can you survive outside a plane?

One in four plane stowaways can survive, but London case is astonishing. … But normally the combination of cold, lack of oxygen and air pressure experienced at a plane’s cruising height, outside the artificially maintained conditions of the cabin, would prove fatal.

## Why do planes not freeze in the air?

The absence of water in colder temperatures means there is nothing to form ice from. … At an altitude of 35,000 feet, however, the clouds are made of ice crystals so no supercooled droplets exist thus, airplanes do not face icing issues.

## Can airplanes fly in extreme cold?

How Cold Can Planes Fly? Essentially the higher you fly, the colder it gets. If the temperature at ground level was 20 degrees Celsius, at heights of between 30,000 feet and 40,000 feet it would be between -40 and -57 degrees Celsius.

## At what temp does jet fuel freeze?

Jet A-1 is a kerosine grade of fuel suitable for most turbine engined aircraft. It has a flash point minimum of 38 degrees C (100°F) and a freeze point maximum of -47 degrees C.

## What is the coldest place on Earth?

Oymyakon is the coldest permanently-inhabited place on Earth and is found in the Arctic Circle’s Northern Pole of Cold.

## What would happen if a window broke on a plane?

Basically, the air pressure inside the cabin is higher than it is outside of the plane to enable the people onboard to breathe normally. That’s why, if a window happens to break, the air inside would escape at high speeds, taking small objects like phones or magazines (or sometimes larger things, like people) with it.

## 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 above rain?

Rain doesn’t usually affect a flight much. Combining with hefty winds causes extra challenges to flight planning. … Heavy rain could affect visibility, but planes generally fly on instruments anyway, so this will not be an issue in itself.

## How tall is a plane?

Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman. Planes can fly much higher than this altitude, but that can present safety issues.

## Can humans breathe 30000 feet?

Above 28,000 to 30,000 feet with extra oxygen under pressure — normal consciousness and life can be sustained to 50,000 feet. … With that medical mask, 100 percent of what the patient is breathing is oxygen and thus all the atmospheric pressure is available to help oxygenate the blood, and that makes a real difference.

## Does 30000 feet have oxygen?

This chart extrapolates effective oxygen percentages to real altitude. At real altitude, the barometric pressure of the atmosphere is significantly less than that of sea-level environments.
