Why did the plane crash?
Planes are actually the safest means of transportation in the world.
According to statistics,
An airplane will have two accidents every 6,543,800 hours on average.
So what was the cause of the plane crash?
The first is natural factors.
The biggest culprit of the accident is the bad weather.
Bad weather,
Caused countless air crashes,
The weather has a great influence on flying.
Interference airflow over air routes or airports,
Severe weather such as typhoon, thunderstorm, fog and hail,
Will be interested in aircraft structure and communication equipment,
Moreover, the take-off and landing of aircraft poses a direct threat.
According to statistics,
There are two air crashes caused by lightning every year on average in the world.
Besides,
And electromagnetic interference.
When boarding the plane, the stewardess will remind everyone to turn off their mobile phones.
Why is this?
This is because any radio communication equipment
It needs to occupy certain spectrum resources for communication.
Mobile phones radiate electromagnetic waves when they work.
Mutual interference is possible,
The receive signal is deviated,
Even interfere with the control system of the aircraft,
So as to perform an erroneous operation,
Causing danger and even plane collision.
In addition, electromagnetic waves generated by astronomical phenomena such as the Northern Lights and sunspots.
It will also interfere with the normal navigation of the plane.
Secondly, human factors.
Although human factors are the number one cause of air crashes,
Including whether the inspection and maintenance of aircraft are in place, the quality of pilots,
Command error in the command management system,
Management imbalance and many other factors.
But as the saying goes, "Listen to your destiny as best you can",
As long as people do their homework on aircraft safety,
Pay enough attention to it,
I believe this kind of risk can be avoided!
There was an accident!
Bird collision, hijacking, etc. are all the reasons for the plane crash.
Among them, the plane hit the bird,
It is a typical accident that many pilots are most worried about.
Because the plane flies very fast in the sky,
Birds are small,
Hit any point on the plane,
Will have a great impact.
Thus causing the plane to explode or crash,
Caused a major air crash.
Terrorists hijack planes,
It is also one of the reasons for air crashes in recent years.
Like buses and subways,
Hijacking can also happen on an airplane.
Although the airport security check is perfect,
But you can't avoid people with ulterior motives.
Many times it is gangsters who are violent.
The plane went out of control and crashed.
Finally, aircraft hardware failure,
Despite the ever-changing quality of aircraft design and manufacturing,
However, equipment failure still accounts for 20% of the causes of aircraft accidents.
Although today's hardware is obviously much more reliable than it was half a century ago
But catastrophic failures still happen from time to time.
Such as engine failure, hydraulic failure, oil tank failure, metal fatigue, etc.
Such as the engine failure of Boeing 777,
Related video evidence shows that,
Shortly after the plane took off,
There's an engine failure,
Parts on the plane,
Fall into local residential areas,
Fortunately, there were no casualties.
Modern aircraft are characterized by heavy load and high speed.
For aircraft and its control system,
The reliability of the braking system is very high.
Therefore, the requirements for engineering maintenance are very strict.
Must meet the requirements of various specifications and parameters,
And strictly check before use.
