What is the air temperature at 35000 feet?

The air temperature at 35000 feet depends on a few variables, such as the season, geographic location, and time of day. Generally speaking, temperatures at 35000 feet can range from -40°F (-40°C) to -80°F (-62°C).

Factors like latitude, altitude, the position of the sun, and the composition of the atmosphere can also affect the temperature. In areas near the equator, for example, the air temperature is usually warmer than areas near the poles.

During the day, the air temperature is usually warmer than during the night, and air temperatures can vary significantly at different altitudes.

How cold can it get at 30000 feet?

At an altitude of 30,000 feet, the approximate temperature outdoors is around -57 degrees Celsius or -71 degrees Fahrenheit. This is significantly colder than most people experience on the ground due to lower air pressure.

At such a high altitude, the air pressure is much lower, causing the air molecules to spread further apart and cool much quicker than at sea level. The conditions are so extreme that most aircraft engines will not function properly and most people can not survive in this environment for more than a few minutes without a pressure suit or pressurised container.

Additionally, the air at this level is much too thin for the human body to receive enough oxygen to sustain itself and survive. Due to these conditions, it is not a desirable or recommended place for people to be.

Can humans survive 45 degree weather?

Humans can theoretically survive 45-degree weather but it is not necessarily ideal and could be dangerous. During extreme cold weather, the body’s metabolism rate decreases and the body is forced to burn fat, carbohydrates, and proteins for energy.

This can lead to extreme fatigue and the risk of hypothermia and frostbite. Therefore, it is important to take the necessary precautions to stay safe in such conditions. Wearing several layers of clothing, including a waterproof outer layer, will help to maintain body heat.

Using hand and foot warming products, avoiding alcohol, and limiting time outdoors can also help one stay safe in cold weather. Being aware of the signs of hypothermia, such as shivering, feeling dizzy, having difficulty speaking, and lack of energy, is important and medical attention should be sought immediately if these symptoms are experienced.

Is it ever too cold for a plane to land?

While the temperature of an environment can affect the performance of an aircraft, it is highly unlikely that it is ever too cold for a plane to land. Sub-zero temperatures reduce the air density, making it more difficult to generate lift for takeoff and for the plane to produce sufficient power for landing.

Consequently, this changes the aircraft’s performance characteristics and puts an extra burden on pilots, but extreme cold weather itself would not prevent the plane from remaining airworthy and able to land safely.

The risks that arise due to cold weather are largely dependent on how well the plane is designed and maintained. Sub-zero temperatures can cause icing on wing surfaces and in engines, reducing thrust and lifting power.

Aircrafts should be properly de-iced before takeoff in cold weather, to prevent formation of ice or snow on the wings and body, which affects the ability to make a safe landing. Cold weather can also damage aircraft systems and components that took too long to warm up after takeoff.

Prolonged exposure to cold temperatures can cause aircraft parts to contract and expand, leading to component fatigue and structural damage.

For these reasons, large commercial airlines will avoid flying over heavily mountainous areas such as the Himalayas during extremely cold weather. Aircrafts also need to be provided with extra power for takeoff and landing in such conditions.

As such, cold weather can be a factor in flight operations, but is not necessarily enough to prevent a plane from landing.

Can you breathe 30000 feet in the air?

No, it is not possible to breathe 30000 feet in the air without assistance. At 30000 feet, the air pressure is too low for humans to breathe without assistance. At this altitude, the air pressure is too low to support efficient oxygen exchange in the lungs, and oxygen levels quickly drop to a dangerous level.

To cope with this lack of oxygen, climbers and pilots need to use supplemental oxygen and pressure suits to supply the additional oxygen they need to remain conscious and alert. Without these tools, humans cannot survive more than a few minutes at this altitude without oxygen.

Why jet fuel does not freeze?

Jet fuel, typically a composite of a number of compounds, does not freeze because of its relatively high flash point. The flash point is the temperature at which a liquid will ignite when exposed to an open flame, and for jet fuel, this is typically around 130-180°F (54-82°C).

This means that at normal air temperatures, the fuel remains in liquid form. Additionally, jet fuel is typically treated with additives like corrosion inhibitors, antioxidants, and antistatic agents to make it even more temperature resistant.

In addition to its relatively low flash point, jet fuel also has a low freezing point. Freezing point is the temperature at which a liquid turns to a solid, and the freezing point of jet fuel is typically around -45°F (-43°C).

This means that at normal air temperatures, the fuel remains too warm to freeze.

Alternative jet fuels, such as bio jet fuel, also typically have higher flash points, making them especially resistant to freezing. This is especially helpful for areas with colder climates, where alternative jet fuels can still be used safely.

In conclusion, jet fuel does not typically freeze because of its relatively high flash point and low freezing point. Its resistance to freezing is often increased with additives and alternative jet fuels have even higher flash points for extreme climates.

Why is air so cold at 30000 feet?

At 30000 feet, you are essentially in the upper atmosphere where the temperatures are much colder than nearer the ground. This is because the higher you go, the colder it gets due to lower atmospheric pressure.

Air pressure is caused by the weight of the air pressing down. The higher up you go, the less air there is and therefore the pressure is lower. As a result, the temperature decreases with altitude. This is why the air is colder at 30000 feet and why planes often fly at an altitude where the air pressure is lower and there is less air resistance.

What do pilots see when flying?

Pilots see a variety of sights when flying. Depending on their location and time of day, pilots may be able to appreciate the beauty of sunrises and sunsets, picturesque landscapes, and cloud formations.

During the day, they are exposed to the brilliant blue hues of the sky, impressive mountains, expansive oceans, and rolling hills. During nighttime flights, they can view star-filled skies, the curvature of the earth, and city lights below.

In general, pilots experience a sense of freedom and tranquility, allowing them to appreciate the power of human flight and the beauty of nature at the same time. They also have the privilege to observe rapidly changing weather patterns, bustling commercial activity in airports, and other aircrafts in the vicinity.

All of these elements come together to create a unique, unforgettable experience for pilots, no matter where their journey takes them.

At what altitude does air get colder?

The altitude at which the air will get colder is largely a function of the weather patterns in the region, but typically the air will start to get significantly colder as you climb higher in altitude—starting as low as 2,000 feet above sea level.

The primary factor influencing temperature at higher altitudes is the decrease in air pressure. As the air pressure decreases, the air expands and becomes less dense, therefore trapping less heat. Additionally, as altitude increases above sea level, the air also tends to get drier.

Dry air absorbs less heat than moist air, further contributing to the decrease in temperature.

For example, the average temperature in Denver, Colorado is between 55 and 80 degrees Fahrenheit (or 13 and 27 degrees Celsius). At 6,800 feet of altitude, the temperature is usually around 15 degrees Fahrenheit (or -9 Celsius) colder than the city’s average; while at 10,000 feet, the temperature is usually 18 to 23 degrees Fahrenheit (or -8 to -5 Celsius) colder.

Temperatures can easily drop below freezing at windy or mountainous areas, even in the summer. Therefore, it is important for hikers and mountain climbers to be aware of their altitude and dress warmly in anticipation of colder temperatures as they move higher in altitude.

Can you hear a plane at 30 000 feet?

No, it is not possible to hear a plane flying at 30 000 feet due to factors like the atmospheric layer and sound waves. Sound waves travel differently in the atmosphere than normal air. It takes them longer to reach the ground, so sound emitted at 30,000 feet would be very faint and possibly not heard at all.

Additionally, the atmosphere itself has a dampening effect on sound due to the thickness of the layer, meaning that even if a person on the ground were to be able to hear a sound from that high up in the sky, it would be significantly reduced compared to what the passengers in the plane would hear.

At what altitude can planes no longer fly?

The exact altitude at which an aircraft can no longer fly depends on a variety of factors, including its design and build, the performance and efficiency of its engine, and the air pressure at the altitudes it is attempting to reach.

Generally speaking, aircraft can no longer fly above 40,000 to 50,000 feet (12,192 to 15,240 m), as the thin air and decreased air pressure make it difficult for wings to generate lift. Airliners generally cruise at altitudes between 30,000 and 40,000 feet (9,144 to 12,192 m), while military aircraft are capable of flying as high as 70,000 feet (21,336 m).

The altitude record for the highest level ever reached by an aircraft is held by the SR-71 Blackbird, when, in 1976, it flew at 85,069 feet (25,929 m).

Is it safe to fly at 40000 feet?

Flying at 40,000 feet is generally considered to be safe and is primarily used for long-distance air travel. Commercial aircraft typically fly between 30,000 and 40,000 feet and modern planes are built with all necessary safety features to ensure a safe flight at this altitude.

At this altitude, the aircraft encounters less oxygen and thicker air. This, coupled with higher speeds and greater altitude, means pilots can experience different types of turbulence. Such turbulence could cause unattached objects to become airborne, cause discomfort and make it more difficult to control the aircraft.

As a result, the flight crew will be more cautious in this altitude band, and the pilots may decide to slow down the aircraft or even drop altitude to reduce the effects of turbulence.

The atmosphere is much thinner at 40,000 feet, and the air pressure is less. This can lead to some discomfort, fatigue and dehydration in passengers, which could manifest itself through headaches, lightheadedness, dizziness and other symptoms.

Passengers can avoid such issues by staying hydrated, wearing loose clothing and avoiding alcohol.

Overall, flying at 40,000 feet is safe, but passengers should be aware that the environment can be uncomfortable or difficult to navigate. By following their flight crew’s instructions and staying hydrated and comfortable, passengers can avoid issues and enjoy a safe flight.

How hot are jet fighter planes when flying?

Jet fighter planes can get very hot when flying, especially when flying at higher altitudes where there is very little air to cool the engine. At high altitudes, temperatures can reach up to 400 degrees inside the cockpit, making it very uncomfortable for pilots who are required to wear full flight suits and helmets.

Additionally, the exterior temperature of the aircraft can reach up to 500 degrees, making it one of the hottest pieces of military hardware in the sky. To combat the extreme temperatures, jet fighter planes are equipped with sophisticated cooling systems like air or liquid cooling systems or thermal insulation.

This helps regulate the temperatures so the jet fighter can perform optimally during aerial combat.
