There are 10 special rules that are unknown when you're on a plane. Special services really exist. 99% of people don't know. You have to be careful when you're on a plane. In the transportation tools that modern people use, airplanes have become everyone's primary choice. But there are a lot of rules when you're on a plane. A lot of the rules are not known to everyone. Some of these rules are about the crew. Some are about passengers. Some are some cold knowledge hidden in the process of flying. These knowledge even reveals your key information. A lot of people don't know these information. First place, everyone makes mistakes. 99% of people don't know the right way. The world is so big. Today, let's take a look at the 10 special rules that are unknown when you're on a plane. I'm sure you'll open your eyes. The 10th small round hole on the plane glass. A lot of people will find a very small round hole on their window when they're on a plane. But a lot of people don't know what this little round hole does. In such a closed environment, why do you have to keep such a small round hole? This little round hole on the plane window is usually very small. The size of a hole is only a few centimeters. It's in the middle of the bottom of the window. If you don't look at it carefully, it's hard to find out the function of this round hole. Before that, let's talk about the window structure of the plane. The window of the plane is usually made up of three layers of reinforced glass. The glass in the middle is the part that directly touches the passenger. Its main function is decoration and soundproofing. Only the outermost part is the structure of the whole plane. It's also the part that bears the pressure of the whole plane. When the plane climbs to an altitude of several thousand meters, the air is relatively thin and the air pressure is relatively low. If you let the passengers in the cabin directly touch the air outside, a lot of passengers will inevitably lose their breath or feel unwell. At this time, you need to adjust the cabin inside the plane. Let the cabin inside the plane be relatively high, which is not much different from the ground pressure value. At this time, you can understand the plane as a long-distance flying pressure pot. There must be a device that can be adjusted. It requires internal and external pressure to maintain a relative balance. And this little hole just acts as a regulator. As the altitude continues to rise, the external pressure will also be tightly attached to the glass surface. If the air pressure outside the glass is not distributed at this time, it will cause the glass to crack. And this little hole on the window officially plays the role of balancing air pressure, allowing the external low blood pressure to be fully distributed to the other two layers of glass. In this way, the external air pressure is reduced. This little hole on the window can also be understood as a pressure gauge. In addition, it also has the function of removing fog and frost. When the plane flies at an altitude of about 10,000 meters, the temperature outside the plane is very low. At the lowest temperature, it can reach minus 50 degrees Celsius. At this time, once there is moisture on the surface or inside of the window, fog and frost will appear. It is necessary to know that the effect of fog and frost on the plane is far higher than fog and frost on the ground glass. This will not only increase the weight of the plane, but also cause a speed-breaking effect. That is, when the plane descends from a height of 10,000 meters to a height of several thousand meters, the glass of these freezes will be very fragile. Once it is shot at high temperature by the sun, the glass on the outside may break directly. Therefore, these small holes can also avoid the production of moisture and ensure that passengers can see the outside sky environment. Many people also say that when they take a plane, there is no such small hole on their plane. This small hole does not exist on all windows. It only exists on individual window glasses. As for why it was designed as a circle, there is a saying. In the 1950s, there was an avalanche of square glass. If the rotation of the plane or this small hole is designed as a square, then the pressure inside the cabin and the external pressure will produce an extreme compression and expansion. At this time, its pressure will spread to the edge of the window, and concentrate on the sharp corners of the glass, which can easily cause the glass to break and the fuselage to break. If it is a round or oval structure, then these pressure walls will continue to dissipate with the flow of air, to avoid the constant increase of destructive pressure throughout the process. The ninth plane cannot be slacked off. In the process of taking other transportation tools, many passengers will choose to take off their shoes in long-distance travel to fully relax their feet. However, in the process of aviation flight, it is strictly prohibited to take off your shoes. There are also relevant regulations. According to the aviation company, it is not allowed to wear slippers during the flight. What are the reasons for this? An aviation company's engineering introduction said that if an accident occurs during the flight, barefoot or wearing slippers may even cause you to lose your life in the air. This is mainly because if the plane has an accident, then some of the objects in the plane will fall apart, and there will be some broken metal fragments in the cabin of the plane. If these substances are inserted into the foot, it will cause a large bleeding of the human body, and there is no way to get treatment and bandage in the first place during the flight. So this situation is very dangerous. And it is extremely inconvenient to wear slippers and barefoot during the escape process. If the escape speed is not fast enough, it may also pose a safety threat to the lives of other passengers on board. In addition to all this, there is another regulation, that is civilization. Many passengers will smell very bad after taking off their shoes. This not only affects the passengers' flight experience, but also makes this smell difficult to get rid of. Because the air pressure in the cockpit is relatively stable The air circulation in the cabin and the external environment is very slow. This also causes this unpleasant smell to last for a long time. So at a critical moment, you must wear comfortable shoes. If there are other attachments on the ground, or if you wear shoes on fire, it will be extremely important. Especially if the plane crashes, and lands in the deep mountains, barefoot will be more difficult. Wearing slippers is also the same. When the eighth plane takes off, you must turn on the backlight. When you are on the plane, you will definitely hear this sentence, that is, the airport requires passengers to turn on the backlight. I believe that many people prefer to choose a position near the window when they are on the plane. Here you can not only jump far into the sky, but also watch the picture when the plane lands. But when flying in the sky, the direct strong light will also make many passengers uncomfortable. So under subconscious conditions, you will choose to turn off the backlight. When landing is the most critical time of the plane, you must turn on the backlight at this time. What are the reasons for this? A famous British comedy actor, Jack Whitewall once told his own personal experience. In the process of taking off, the airport told him that as a passenger, when you turn on the backlight, you can immediately observe the work of the engine. If there is any bad reaction on the plane, you can help the pilot to observe. The backlight is a substance in the cabin of the plane. It can block the sun, and avoid direct protection. When flying in the air, it can also play a role in noise reduction. Especially when flying at a distance of 10,000 meters, the backlight can also play a role in heat insulation. In general, when the plane takes off, turning on the backlight also helps passengers to better observe the outside environment, while providing enough light to illuminate the cabin. This mainly allows passengers to adapt to the outside light environment This is a bit like when you come out of a dark tunnel, you have to cover your eyes as soon as possible to avoid being stimulated by external light. After the plane turns on the backlight, it will also turn off the light inside so that passengers can get in touch with the outside light and take the initiative to adapt. In all flight history, the backlight is used. Another advantage is that it can allow passengers to observe the outside environment in time to avoid negative emotions such as fear disorder or anxiety disorder. During a flight, due to the long time of turning off the backlight, a passenger in the cabin suddenly became extremely panicked and almost caused a flight accident. In 2017, on the way to Italy, sprayed a lot of aerosol from the outside of the plane to the sky. The passengers sitting by the window immediately reported everything to the flight crew. The flight crew also made a decision to return to the aircraft based on this safety situation and ensured the safety of the 195 passengers on board. The seventh passenger must turn off his mobile phone when boarding the plane. Flight attendants usually ask passengers to turn off their mobile phones when taking off and landing. If you do not follow such a rule, you may be punished. In 2017, on a flight from Harbin to Beijing, a female passenger repeatedly refused the request of the flight crew to turn off their mobile phones. After arriving in Beijing, she was detained by the public security department. At the same time, there are different ways to turn off mobile phones in different countries. So why turn off your mobile phone? During the flight, especially before taking off, the communication tower is the busiest. You need to communicate with the tower in time about the flight situation and the flight route. At the same time, takeoff and landing are also the main stages of most flight accidents. If the communication is not good or the connection situation is not clear, the pilot cannot accurately grasp what speed the plane should take off and what position to enter its route These information need to be informed by the tower to the captain. The tower is like the eyes of the whole plane. If the passengers in this short flight use a lot of mobile phone communication signals, there is a possibility that the plane is in a hurry. There may be a group of planes landing, but this group of planes take off for a long time. And because the passengers are relatively concentrated, when they connect to the Internet, they usually connect to a base station. Think about it. If a large number of passengers connect to a base station at this time, it will inevitably cause a blockage of the Internet channel. As for the tower, it also needs the help of the Internet. If the Internet is not good or the Internet is not connected, will there be flight accidents? Many people believe that a key word called flight mode Is it really okay to turn on flight mode? In many airlines in our country, they do not recognize flight mode. Airlines generally think differently. There is a certain difference in the technical training of flight mode for mobile phone manufacturers. And airlines can't verify their passengers' mobile phones at the first time. So in order to better ensure flight safety, the most direct approach is to turn off the mobile phone when taking off and landing. There are many different perceptions In many foreign airlines, they do not control the Internet for passengers using mobile phones. They also provide Wi-Fi hotspots, Bluetooth, etc. Compared to our country, they are relatively rigid. These airlines also usually adopt a one-cut method. This is extremely wrong and does not fully guarantee the interests of passengers. When traveling long distances or taking a plane, you must have heard of the saying that you can't carry more than 20,000 mAh chargers and you can't carry two chargers. What is the main reason? When we travel abroad, chargers have become a necessity for us. But when we take a plane, if we carry too many chargers, we will be confiscated by the airport security personnel. Many passengers do not understand this. There is no clear understanding of how large a charger can be carried. According to our country, according to the regulations of the Civil Aviation Passengers Carrying Charger Regulations, it is not allowed to carry more than 160Wh chargers when traveling by plane. Chargers less than 160Wh must be approved by the airline and cannot exceed two chargers. If this data is converted, 20,000 mAh is a limit. As long as it is not more than 20,000 mAh, it can be carried. And chargers are not allowed to be placed in luggage. It can only be carried. At the same time, there are many requirements for For example, this charger must be produced by a regular manufacturer and has a clear label. Chargers that are fake or manufactured by the manufacturer cannot be carried on the plane. For this, the plane's security personnel will conduct a strict inspection These chargers must have national 3C certification. So why is it so strict? This is mainly because a relatively closed flight cabin is a very unsafe material, especially in the process of charging the mobile phone, there is a possibility that the mobile phone will explode or catch fire. If this happens, most of the objects in the cabin are flammable, which can cause serious consequences. And there is a very limited space to escape on the plane. It is impossible for all passengers to jump. Therefore, in order to eliminate absolute security threats, a series of regulations Do you know that pilots can sleep during long-distance flight? Many people find it hard to believe that pilots should drive the plane to ensure safety. How do you ensure the safety of the passengers The pilot is the most important in the entire flight. Not only does he have to ensure the safety of the entire flight, but he also has to pay absolute attention throughout the flight to respond to possible or already occurred accidents. But the pilot is also a person, he will be tired or tired. Therefore, when the plane is relatively stable on the horizontal flight, he can take a nap during the flight. It is necessary to know that the plane is an extremely precise transportation tool. It also has an automatic mode of driving, which is to fly autonomously at the specified route and height. And there are no birds flying in absolute high-altitude conditions. There will be no problems with birds. All flights are approved by the Air Traffic Control Center. Therefore, there will be no crashes or problems with high-altitude flight In the process of flying for several hours in a horizontal flight, the captain or deputy captain can take a break in turn. In many large passenger aircraft in Europe and the United States, a special lounge has been built These lounges are generally arranged at the top of the cabin. There are not only beds inside, but also basic eye protection. This is also to ensure that when the captain is arranged to rest, the deputy captain will serve as the pilot of the entire aircraft, observing the performance of the aircraft and the change of the atmosphere and weather in and out of the aircraft. Once an accident occurs, the captain will be woken up at the first opportunity. Similarly, when the deputy captain enters the lounge to rest, the captain can ensure the safety of the entire aircraft. For example, the flight to the United States took 12 hours. It is impossible not to rest and replenish for 12 hours in a row. Therefore, it is particularly important to ensure that the pilot maintains sufficient physical energy and energy. This is why pilots can sleep This is also a special rule During the flight, the passengers will also have the need to go to the toilet. The toilet on the plane is not like the train on the track, which will directly scatter the excreta on the outside of the plane. This will not only cause the problem of high-altitude dust, but also cause the internal and external air pressure to be out of balance. Therefore, the toilets in the plane are specially treated. For example, in the Indian region, blue ice has been found on the plane. In order to distinguish the excreta from the passengers, a large amount of blue medicine will be used in the toilet. This medicine will make the excreta of the human body distinguished. However, this blue medicine has an obvious side effect, which is that its smell is very strong and can be permeated into the entire cabin. Soon, this blue medicine will leave the flying field and all major airlines will no longer use it. In the past, there were also airlines and air force using mobile toilets. After the excreta is completed, plastic bags will be used to seal these excreta. After the plane lands, these things will be processed. However, if there are fluctuations or other accidents during the flight, the excreta in these toilets will leak out. Not only in the cabin, but also on the wall. The smell in the cabin is even more unbearable. In World War II, German pilots even threw excreta in the toilet as biological weapons into enemy battleships. Until 1982, Boeing first used an electric flush toilet. There is also a blue liquid which is also a special excreta. This excreta can not only separate solid excreta from the human body, but also make the excreta smell dissipate and become a harmless liquid. Of course, this blue excreta is not very secretive. It will often leak out and form fog to the outside of the cabin. In addition, during the flight, the temperature outside is very low and it is very easy to form blue ice. These blue ice will be attached to the bottom of the aircraft and when it drops to a certain height, these blue ice will melt and fall to the ground. In 2016, there was a huge piece of blue ice that hit the roof of a resident's house and caused local residents to be injured. According to the court, the airline not only faces fines, but also huge compensation. Last year, the British Civil Aviation Bureau received a total of 25 reports about the incident of blue ice At present, there is no better way to deal with human excreta in the field of flight. I believe that as technology progresses, and means are increasingly strengthened, the treatment of excreta will be more reasonable. You can't bring water on the third plane. I believe many friends who have seen movies and TV dramas will see such a very absurd scene, which is to drink all the drinks or other liquids you carry but not to write on the paper plane. Before understanding this issue, let's first understand what really happened. One day in 1994, a passenger of the US Northwest Airlines was struck by a thunderstorm in the cabin. And there was only one passenger This is because this passenger was holding a plastic bottle When the cabin was struck by a thunderstorm, these faint currents passed through the water bottle and immediately caused him to have difficulty breathing and discomfort in his body. Fortunately, this passenger immediately received medical help and did not cause serious consequences. But this incident also woke up many airlines, that is, liquids carried by passengers in thunderstorms, stormy weather, or other electrical malfunctions may cause currents to pass through the passenger's body. In 2006, a major flight terror attack took place in the UK. At that time, several terrorists put liquid bombs in plastic bottles and were ready to take off in the air. Fortunately, the British police immediately solved this case. After this incident, airlines around the world have taken very strict control of liquids. In our country, passengers can only carry liquids less than 100 ml. These liquids must be checked and placed in the luggage compartment. In short, the beverage bottle is very dangerous. It can not only cause accidents, but also can be used as a terrorist attack tool. Therefore, for the sake of safety, it is not allowed to carry any liquid or drink water on the plane Of course, if you feel thirsty or need to drink water you can ask the flight attendants. They will pour water for you How to choose the second seat Many people will choose the seat closest to the window when they are on the plane. This is mainly to appreciate the beautiful scenery that can be seen during the flight. Some people will consider the safety when they are on the plane. Some people will choose the seat closest to the exit Some people will choose the seat closest to the front So which position is really safe? Some airlines are more superstitious when they design the flight seat and the flight seat arrangement. For example, the French airline and the Air France airline and the Air Iliya airline do not have a 13th row seat. Some other companies in Europe and America do not have a 17th row seat. For them, these numbers are extremely unlucky and may cause bad things to happen. Many people will choose the safe exit This is mainly because once there is an accident, these people will be the first to escape. Is this really the case? In 2015, the Federal Aviation Administration analyzed the data of plane accidents in the global range. It found that the passenger who sat in one-third of the back seat can reach 68%. The passenger who sat in the middle of the back seat can reach more than 70%. The passenger who sat in one-third of the back seat can only reach about 60%. The minimum survival rate is the middle position, which is close to the national island. This data also shows that it is not the safest to buy a first-class cabin at a very high price. Its survival rate is even less than the survival rate especially when an accident occurs on the plane and an emergency landing is needed. The survival rate of the first-class cabin will be lower. The first-class cabin passengers are not arranged to leave the cabin The middle position of the passengers is the middle section of the entire plane and the most stable part of the entire structure of the plane. There are also large wings on both sides to support it. Whether there is an emergency landing or approaching the ground, it has enough buffer. When an object like a plane approaches the ground, either the head lands first or the tail lands first. There is never a middle position landing first, so the middle passenger is absolutely safe. Do you know how to choose your seat The secret of the first-class cabin We usually get a lot of information This information also includes English and Chinese. Many people don't know what it is and even throw it away. Do you know? Such a small action may leak your key information. The boarding pass is the boarding certificate of the passenger on the plane. It contains a lot of information. For example, the code of your flight, that is, the information of the airline company. The specific boarding and take-off time and your boarding gate and cabin position. Don't underestimate this information. Through a simple boarding pass, you can judge whether you are sitting in the first-class cabin or the economy cabin. These are all reflected in the ticket. For example, the first-class cabin is replaced by F, the business cabin is C, and the economy cabin is Y. In addition, there are other English letters that replace a lot of information. In addition to these information, the boarding pass will also show whether you are a passenger of this airline or a ticket purchased by the agent. These information can reflect your consumption habits, including your travel habits. If this information is obtained by the crew, then it can master your basic itinerary, as well as your fraud and even more serious illegal crimes. At the same time, the airline company will also mark the boarding pass of the passenger For example, the boarding pass will be marked with four letters. This mainly indicates that this passenger needs to accept additional security checks, which is very expensive security checks, including a private questioning in the cabin. This shows that there are dangerous items that can cause a safety incident in the passenger's cabin. Therefore, it is necessary to properly dispose of your boarding pass after all flights, and not to lose it easily. This is an extremely unsafe behavior. All right, that's it. The above are 10 special regulations
