# Question: What Is The Temperature At 40000 Feet?

## Do planes eject toilet waste?

Some lavatory excrement had leaked out.” Do airplanes ever dump their waste while in flight.

Not intentionally.

(The noise may make it seem like the toilet is flushing your waste out into the atmosphere, but it’s not.) Under normal circumstances, the ground crew disposes of the sewage after the plane lands..

## Do Planes fly over Mount Everest?

According Debapriyo, most commercial airlines avoid flying directly over the Himalayas. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”

## Can a plane fly at 60000 feet?

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. The highest business jet flying today reaches 51,000 feet.

## How cold is the air at 35000 feet?

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.

## Can planes fly at 50000 feet?

Currently, no passenger airplanes are “able” to fly at 50,000 feet or above. Because, at these altitudes, air density is very low, which wouldn’t sustain the heavy weight of the passenger aircrafts. Commercial airplanes have an Absolute Ceiling of 43000 feet.

## Do pilots get scared of turbulence?

In short, pilots are not worried about turbulence – avoiding it is for convenience and comfort rather than safety. In the best circumstances, pilots can forecast where turbulence is and steer clear of it. “We use met data and forecasts for jet streams to avoid potential areas,” the pilot said.

## Why do planes not freeze in the air?

Airplanes can’t freeze because of course they’re not made of water. In a sense, the materials they’re made of are already “frozen” solids at the temperatures they operate in.

## Why do pilots prefer to fly at 36000 feet?

The first is the thinner air. Since 36,000 feet is a further 7000 feet higher than the peak of Mount Everest, the air up there is pretty thin. That allows the aircraft to travel faster while using less fuel. Flying at this height also lessens the chance of a plane coming into contact with something else.

## Why do planes fly at 40000 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.

## How cold is it at 38000 feet?

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.

## Do Flights take off in thunderstorms?

Jet aircraft can safely fly over thunderstorms only if their flight altitude is well above the turbulent cloud tops. The most intense and turbulent storms are often the tallest storms, so enroute flights always seek to go around them. … Flights avoiding New York area weather-impacted airspace on September 11, 2013.

## What is the temperature at 36000 feet?

On aircraft which fly above 30,000 feet, the temperature can often can get to temperatures below Jet-A’s freezing point. For example: at 36,000 feet the standard outside air temperature is -56.5°C (-69.7°F) and is well below Jet-A’s freezing point of -40°C/F.

## Which airline crashes the most?

Which Airlines Have Had the Most Plane Crash Deaths?Malaysia Airlines: 298 deaths from one crash (2014, Ukraine)Ethiopian Airlines: 247 deaths from two plane crashes (most recent: 2019, Ethiopia)Lion Air: 181 deaths from two plane crashes (most recent: 2018, Indonesia)More items…•

## Which airline has never had a fatal crash?

The Virgin group of airlines has never had a fatal crash. Virgin Atlantic began operating in 1984 and serves 33 destinations around the world, while Virgin Australia was founded in 2000 and flies to 52 destinations.

## Do planes stop in mid air?

No a plane doesn’t stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). What it can do is simply turn around or go over/under the obstruction. VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.

## Can a human survive at 37000 feet?

Between 62,000 and 63,500 feet (18,900 and 19,350 meters) blood begins to boil at body temperature. This altitude, referred to as the Armstrong limit, is generally considered to be the absolute limit compatible with life. At this point, humans cannot survive without pressurization measures.

## Why do planes 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. … Whether a commercial airline is flying from the United States to Asia or elsewhere, it will have the fastest and most fuel-efficient flight by performing a curved rout.

## Do flight attendants ever get scared?

As a flight attendant, it’s our job to ensure the cabin is safe and secure. … Cabin Crews are never scared of turbulence and are highly trained to react and deal with turbulence and other on-board situations that may arise.
