What does an aviation accident mean? What are the chances of an accident with an aircraft

Aviation accidents are accidents caused by collisions and self-failures of aircraft in space flight, including airplanes and other aircraft, just like traffic accidents.

It's that the plane flew in the sky and broke down.

There was an emergency.

It's an accident that happens when the plane is flying!

1. Natural factors.

1. Inclement weather.

There are countless air accidents closely related to weather reasons, such as the Yichun air crash in 2010, the Pakistan air crash and the crash in Poland**, all of which were accompanied by dense fog.

2. Electromagnetic interference.

Why is it dangerous to use a mobile phone on a plane? It turns out that the navigation equipment on the aircraft uses electromagnetic waves to determine the direction, and it can measure the accurate position of the aircraft after receiving the electromagnetic waves continuously emitted by the ground navigation station.

2. Human causes.

1. The pilot made a mistake in maneuvering.

This kind of accident is not uncommon, after all, pilots are human beings, and even if they are professionally trained, there is no guarantee that they will never make mistakes.

2. Ground staff maintenance errors.

Including improper loading and unloading of ground crews, illegal maintenance, etc., which is equivalent to placing a time bomb on the aircraft, accidents may occur at any time.

3. The pilot's ground staff communication error.

In the 1977 Tenerife air disaster, the deadliest in aviation history, 583 lives were innocently lost due to a language barrier between pilots and ground crew.

4. Plane collision.

You may wonder how two planes collide when the sky is so big, but in fact, this kind of accident can still happen. Although the space in the sky is large, people still draw a "corridor in the sky", just to prevent collisions, a passenger plane can only fly in its own corridor to avoid collisions.

3. Hardware failure.

1. Engine failure.

The engine is the device that provides thrust to the aircraft, without which the aircraft cannot fly. However, in fact, engine failure is far less terrible, today's airliners have more than two engines, and if one breaks, it will generally not cause an accident that destroys the plane and kills people.

2. Hydraulic failure.

On airliners, hydraulic pipes connect the pilot's pedals and handles, to all the control surfaces of the aircraft, ailerons, lift surfaces, and so on. It can be said that the aircraft is completely controlled by its hydraulic system.

3. The fuel tank fails.

Jet fuel is very explosive in its vaporized state. It sounds scary, but in fact, there are very few accidents caused directly by the tank**.

4. Metal fatigue.

An airplane is a combination of a complete set of systems, and the failure of any one system can cause an accident. The most common cause of failure is metal fatigue, as in the case of the consequences of you repeatedly bending a pin.

Therefore, for those of us who take planes, we should usually master more knowledge of emergency self-rescue in aircraft accidents to prevent real accidents from coming and our minds are blank.

Generally speaking, the occurrence of air accidents can be attributed to the following three reasons: the design defects of the aircraft itself, human factors (including pilot operation error, ground maintenance engineers not operating in accordance with regulations, air traffic control command errors, etc.) and natural factors.

1. Mechanical failure.

2. Harsh climate.

3. Electromagnetic interference.

4. Fuel tank**.

5. Big bird attack.

According to statistical data (1993-2012), the probability of a plane crash in 78 major airlines in the world is 1:4700000. This means that the probability of 3 air crashes a year is 1 in 100 million.

Statistical table of causes of air accidents from 1950 to 2000 (percentage):

One of the most significant inventions of the twentieth century was the birth of the airplane. At the beginning of this century, there was a pair of brothers in the United States who made significant contributions to the history of the world's aircraft development, and they were the Wright brothers.

1. The first airplane was born.

From 1900 to 1902, the brothers conducted more than 1,000 gliding test flights, and finally in 1903 they built the first manned aircraft, the "Flyer" 1, which was successfully tested on its own power. They were awarded the U.S. Congressional Honor Award in 1909. In the same year, they founded the "Wright Aircraft Company".

This is a great success of mankind in the history of aircraft development.

2. The invention of the twin engine system.

In 1911, the British Schott brothers applied for patents for the design of several engines. Their twin engine system allows every pilot to avoid having to lower the aircraft due to engine shutdown. This is a significant step forward in aviation safety.

The first aircraft built under SCHOTT's patent was called the "3 2" aircraft.

3. Application of gyroscope technology.

Between 1927 and mid-1932, progress was made in the development of cockpit instruments and navigation equipment, and gyroscope technology was applied to flight instruments. The rotating flywheel, mounted on a gimbal mount, maintains orientation in space and serves as the basis for a variety of navigation instruments that guide the driver to fly in the dark, rain or snow.

According to statistics, the airline with the most accidents in China is China Eastern Airlines (hereinafter referred to as China Eastern Airlines). According to the figures released by the Civil Aviation Administration of China, between 2014 and 2018, China Eastern Airlines had three serious accidents, involving more than 200 dead and injured passengers. One of the most serious accidents occurred in March 2016, when a slaggy China Eastern Airlines-operated aircraft lost control while landing at Nanjing Lukou International Airport, causing serious damage to the aircraft, killing two people and injuring five others.

However, it should be noted that the safety level of domestic airlines is relatively high as a whole, and each airline has a strict safety management system and standards.

The main reason is Boeing aircraft.

It accounts for a high proportion of civil aviation crews, so as long as it is a plane crash, Boeing.

How many points. In addition, Boeing's system is also questionable.

Among China's passenger aircraft, the two commonly used ones are Boeing and Airbus. This is equivalent to having only two options, and it is known that a thing will fail after a long time, so in the case of only two brands, it is either one or two, and Boeing accounts for the majority of civil aircraft, so as long as there is a failure, it is not surprising that most of them are their models.

Judging by the data of the two of them, Airbus aircraft.

The crash rate is indeed higher than that of Boeing. And, on the means of transport.

It is true that the accident rate of airplanes is the lowest, but as long as it is a crash, the fatality rate.

It is also the highest. This also caused the plane to either not have an accident, and even the last words did not have time to leave in the event of an accident.

Let's talk about Boeing, this company is an American company, and among the few countries that know about aircraft accidents, it seems that the relationship with the United States is somewhat delicate, but there is no evidence. Look at the black box when the time comes.

Let's look at the analysis results, everything is speculation now. It's just that sometimes many people's speculations are infinitely close to the truth.

There are many reasons for aircraft accidents, one of which is the failure of the instruments and equipment on the aircraft, in these accidents, the crew's ability to deal with the situation is tested, but it does not mean that the flight system itself is not problematic.

I believe that before the China Eastern Airlines accident, few people really paid attention to the plane, however, after this accident, many of us really understood that our plane was not domestic. So, do we have the ability to make domestic products now?These are things that our scientists need to achieve.

The previous high-speed rail was built from scratch, and I believe that the same is true of airplanes.

In general, the recent plane crash actually sounded a warning bell for us, sometimes relying too much on foreign technology, there is a certain threat to the safety of our own people, the country is slowly becoming stronger, and all aspects have to be filled with the efforts of several generations. May every plane land safely after takeoff.

Because the production of Boeing aircraft is very high, most airlines use Boeing aircraft, so recent aviation accidents are Boeing aircraft.

The cause of each accident is completely different, but this series of aircraft may have serious quality problems, or it may be caused by pilot error, except for the Boeing series of aircraft, the crash rate of other aircraft is relatively high, but in the airlines are basically 80% of the Boeing series of aircraft.

Because most of the aircraft used in civil aviation companies are Boeing series aircraft, the probability of accidents is relatively high, after an aviation accident, there may be a problem with the configuration of the aircraft, or it may be caused by the wrong operation of the pilot.

It may be due to the high probability of failure of the Boeing aircraft, or it may be that there is a problem with the quality of the Boeing aircraft, or it may be that so many failures will occur when the service life is reached.

Summary. Dear and hello, the airline with the most accidents in China is China Eastern Airlines. As one of the most powerful state-owned airlines in China.

1. The creator of China's civil aviation safety record, China Eastern Airlines has always been famous. But all of this collapsed with the crash of flight MU5735 on March 21, the aviation giant, which has had a total of 30 accidents since its inception, with at least 300 accidents and 1,000 unsafe accidents behind it.

Dear and hello, the airline with the most accidents in China is China Eastern Airlines. As one of the most powerful state-owned airlines in China.

1. The creator of China's civil aviation safety record, China Eastern Airlines has always been famous. But all this collapsed with the fall of flight MU5735 on March 21, the aviation giant that has had a total of 30 accidents since its inception, with at least 300 accidents and 1,000 unsafe accidents behind it.

But according to the global airline accident rankings, Chinese mainland airlines are not at the forefront. China's safety work in the field and air space is still in place. According to data from the Civil Aviation Administration of China, the major safety accident rate of Chinese mainland airlines in 2019 was 7% lower than that in 2018.

Generally speaking, the probability of an aircraft accident in China is 1 in 200,000 on average, sometimes it may be 1 in 1 million, the probability is low, although everyone sometimes sees air crashes on TV, but once an accident occurs, the aviation industry will pay great attention to it, and at the same time will carry out a lot of work to improve safety.

The aircraft is actually a relatively safe means of transportation, not only will carry out a variety of simulations before traveling, but also a variety of inspections, and the service personnel on the aircraft are professional and screened, to believe in their professionalism.

Aircraft are subjected to various simulation tests before leaving the factory, and international regulations require that the wings must be able to withstand times the maximum load, and some wings will not break even if they are bent at 90 degrees, and the entire aircraft is designed to facilitate rapid evacuation.

According to the historical situation, there are three major reasons for air accidents, the first is human factors, the second is environmental factors, and the third is the quality of aircraft, environmental factors include fog and hail and other weather, as well as birds affecting aircraft.
