The safest means of transportation in the world: Why are airplanes afraid of thunder?

Airplane is one of the most common means of transportation in our lives, and it is one of the safest means of transportation today. Compared with trains, cars and other tools, the safety factor is much higher, but as long as there is a problem with the plane, there is basically no rescue. Room. When taking an airplane, we often encounter “aircraft delays”. Except for special circumstances, most flight delays are caused by “thunderstorms and thunderstorms”, which can be said to be too common.

As one of the safest means of transportation in the world, with the highest safety factor, why the plane is still afraid of thunder? This is totally unscientific. What is going on? Let’s explain below. Many people must be very puzzled. The plane is actually afraid of thunder, and now many people may be on the way to “plane delay”.

aircraft

The airplane is one of the most important inventions in the early 20th century. Nowadays, an airplane can carry hundreds of people. As airplanes are updated from generation to generation, they are now divided into two types of airplanes, one is military, and the other is Civil. Those who can ride hundreds of people are definitely for civilian use, and military use generally has two positions. With the continuous development of mankind, the world is also developing larger airplanes, so airplanes have increasingly become an indispensable means of transportation for modern civilization.

The structure of the aircraft is very clear. Except for a few special forms of aircraft, the general aircraft mainly consists of six parts: wing, fuselage, tail, landing gear, control system and power plant. The fuselage is mainly used to carry personnel, cargo, fuel, weapons, and airborne equipment, and the wing is mainly used to generate power, maintain the balance of the aircraft, and so on. The tail is divided into two parts, the vertical tail and the horizontal tail, and it is also mainly to provide aircraft balance.

The landing gear mainly performs functions such as take-off, landing, taxiing, parking, etc. The control system is to execute all the movement processes of the aircraft, and the power device performs the flight for the main activities of the aircraft. Nowadays, the optimization of aircraft is mainly to reduce the flight resistance of the aircraft in the air, to minimize the use of energy, and to provide a faster and more convenient flight mode. This is the basic situation of the aircraft.

Why is the plane afraid of thunder? This is unscientific

Everyone knows that during the flight of an airplane, it mainly touches two areas of the earth’s atmosphere, one is the troposphere, and the other is the stratosphere. The stratosphere is a horizontal sliding mode of air, and it is relatively high from the ground. There are no natural phenomena such as wind, rain, thunder and lightning, so these phenomena only occur in the troposphere. When the aircraft is flying most of the time, it is flying in the stratosphere, which is not only safe, but also avoids the influence of natural phenomena such as thunder and rain.

However, the aircraft always has to go through the process of take-off or landing. Although the equipment on the aircraft is the safest equipment in the world, it can be said that it is not a big problem to be hit by lightning or wind and rain, but for safety, it has to be restricted. “Aircraft delays” occur under climatic phenomena, so every time there is wind, rain, thunder and lightning, there is no way to take off. Of course this is to ensure “100%” safety.

However, even if we are constantly avoiding such natural occurrences, it is very common for aircraft to encounter “thunder” or “lightning strikes”, and most of the aircraft itself is made of light metal, and the entire aircraft body is also very large, so even If it is struck by lightning, the electricity from the lightning strike can be eliminated instantaneously, because the aircraft can be released through the wingtip, the trailing edge of the wing or the discharge brush protruding from the fuselage, so the internal safety of the aircraft can be guaranteed.

Of course, there are a very small number of airplanes that have problems when they are struck by lightning. But on the whole, the aircraft is relatively safe. Even if it is struck by lightning or thunder, it will not threaten the safety of passengers inside the aircraft.

So the problem that everyone thinks of has actually been thought of in the design of the aircraft. The aircraft can withstand lightning strikes with a high probability. Only a few of them may encounter problems, and in order to avoid safety problems caused by rare or very low probability of lightning strikes. , So basically in such extreme weather, you will choose “aircraft delay”, so don’t nag, in fact, it is to ensure safety “100%”, everyone is in a hurry, but for safety, only the “time concept” can be used. Get rid of.

to sum up

There is no “absolutely” safe thing in the world. Although airplanes are among the means of transportation and are called the safest means of transportation in the world, when facing natural phenomena, it is not that airplanes are “fearful” by themselves, but that people are afraid. The plane itself can still be carried, so it is unscientific to say that the plane is afraid of thunder. In fact, people are afraid of it.

Of course, in the use of aircraft, we also have to choose not to fly to ensure 100% safety. So when we are on the plane, we often encounter “aircraft delays”. Don’t be angry. This is completely done by the civil aviation company to ensure everyone’s safety.

Even if the aircraft has lightning protection and other devices, there have been incidents with a small probability. For example, in 2007, the B6205 aircraft flew to the Shenyang maintenance plant and found more than 10 scorched “wounds” on the body. Air China CA4174 landed at Kunming Airport and found the aircraft. A big hole with a diameter of about 50cm and so on, although they all landed safely, but because the accumulation has brought a huge impact on the aircraft itself, it also brings life threats to the people who fly the aircraft.

So this is why it is necessary to avoid this problem as much as possible now. At the same time, even during the flight, if the landing place is known to have thunder and lightning, heavy rainfall and other weather, it must be forced to land at other airports and so on.
