Why do planes not freeze at altitude?

Aircraft fuel

Aircraft fuel

JP-8, or JP8 (for "Jet Propellant 8") is a jet fuel, specified and used widely by the US military. It is specified by MIL-DTL-83133 and British Defence Standard 91-87, and similar to commercial aviation's Jet A-1, but with the addition of corrosion inhibitor and anti-icing additives.

JP-8 - Wikipedia

generally does not freeze at high altitudes because of the very low freezing temperature of the fuel, the limited amount of time spent in the cold environment, and aircraft design keeping the fuel warm either via insulation from the airframe itself or by heating and circulating the fuel throughout the ...

Why do planes not freeze at high altitudes?

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 a plane freeze in the air?

Airplanes do not freeze because designers ensure sensitive components are heated or kept away from snow accumulation, low freezing points of jet fuels, thorough and robust de-icing protocols both on the ground and in the air, and during flight, the air is drier even at higher, sub-zero altitudes.

Can you freeze 30000 feet?

On aircraft which fly above 30,000 feet, the temperature can often can get to temperatures below Jet-A's freezing point.

Why do planes do not fly over the Pacific?

Flying over the Pacific Ocean is avoided by most airlines for most flights because it usually doesn't make sense to fly over it when shorter and safer routes exist. The Pacific Ocean is also more remote and less safe than the Indian and Atlantic Oceans to fly over, resulting in a higher chance of a plane crashing.

Why don't we fly from Alaska to Russia?

Bering Strait Geography

The smaller of these granite islands is American. These islands can be used as a resting point during a crossing of the Bering Strait, however, being in the proximity of Russia's Big Diomede Island will reduce the chance of a successful crossing from Alaska to Russia.

Why do pilots say Roger?

The International Civil Aviation Organization (ICAO) officially defines the word "roger" to mean "I have received all of your transmission." For example, a pilot would say "roger" in response to an advisory from Air Traffic Control.

Does jet fuel gel?

Jet fuel freezes at around -40 degrees Fahrenheit, but it will work just fine as long as it's kept above that temperature on the ground. Once the plane is moving, the fuel is heated as it passes through the engine — and crew members carefully monitor fuel temperatures during flight.

Can planes fly in freezing rain?

Generally airline and passenger/freight carrying operations are suspended during periods of freezing rain. Even without being prohibited by the operators manual, operations in freezing rain are difficult as the applicable Hold-Over Time from an anti-icing treatment is very limiting in freezing rain.

Why do planes stop in mid air?

1 Answer. Show activity on this post. Lowering flaps and gear will add significant drag, which causes the plane to decelerate. Your body feels that, but without visual reference to the ground, your brain has no way to know what speed it was traveling before or after that deceleration.

Can a flight stop in the air without moving?

Can an airplane stay up in the air without moving forward just like helicopter? A: Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare.

Does a plane dump fuel before landing?

Airplane fuel can be quite heavy, sometimes weighing as much as 6 pounds a gallon. If an airplane holds 5,000 gallons of fuel, that can add up to 30,000 lbs. to the plane's weight. In fact, lowering its weight is the main reason why airplanes dump fuel right before landing.

Why do 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. Most commercial airplanes cruise at an altitude of nearly 35,000 feet—around 6.62 miles (10,600 meters) in the air!

Can planes fly at 50000 feet?

The highest that a commercial airplane can fly is 45,000 feet. Most military planes fly at around 50,000 feet and sometimes higher. Some rocket-powered planes can fly as high as 100,000 feet but they are specially designed for this purpose.

Can you breathe at 35000 feet?

Whether you are flying aboard a small Cessna or a jumbo-sized Airbus A380, you can breathe freely inside the cabin without wearing a mask or respirator. Even at a cruising altitude of 35,000 feet, you shouldn't have trouble breathing.

How much does it cost to deice a plane?

The cost of deicing can range for around $1,000 to $10,000 depending on the size of aircraft and airport.

Can planes land in freezing fog?

At those temperatures, a cloud is usually made up of ice crystals. Occasionally, there are supercooled droplets that freeze on contact with the airplane. Good de-icing systems are essential in such conditions. Flying through this condition in a modern airliner with good de-icing equipment is safe.

What happen when lightning strikes a plane?

An airplane can essentially act as a lightning rod. The bolt will initially strike one point, like the nose, and travel through the aircraft to an exit point, like the wing tip. After that, the bolt will continue where it could hit the earth's surface.

Can a car run on jet fuel?

Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. Although, I wouldn't recommend running a jet on diesel.

How much is jet fuel per gallon?

Jet A Fuel

As of April 15, 2021, Jet Fuel A was priced at an average of $4.81 per gallon in the United States. If you multiply that by the typical tank size of a commercial aircraft (3,500 gallons), filling up your plane with Jet A fuel may cost you somewhere around $16,835 in total.

Why is kerosene used as jet fuel?

Aviation kerosene has a freezing point of -47 °C. Planes fly at extremely high altitudes, which means they spend a lot of airtime in sub-zero temperatures. As a result, planes need to use fuel with a low freezing point – like kerosene - so the fuel functions properly without solidifying during the flight.

What does the pilot say before crashing?

Mayday. And that's because it's a word that's been used for the last century to immediately indicate an emergency. The typical way of saying it is to call it three times in a row — Mayday! Mayday!

Why is it Niner instead of nine?

Aviators often speak “pilot English” to avoid miscommunications over radio transmission. “Tree” for instance, means three, “fife” is the number five and “niner” means nine, says Tom Zecha, a manager at AOPA. The variations stemmed from a desire to avoid confusion between similar-sounding numbers, he says.

Why do pilots say rotate when they take off?

Summary. Long story short, pilots say rotate as a verbal queue that the aircraft has reached its predetermined V_r and hence appropriate inputs can be applied to safely pitch the aircraft in a nose-up attitude to gain lift.
