In real life, many people need to fly frequently, often at home and abroad, some are busy with business elites, and some are experts and scholars who go to various places for exchanges and learning.
Regardless of the type of people, airplanes are their preferred means of transportation, but even so, there are still some people who are very reluctant to take planes, and the reason is simple, that is, the safety of planes makes them worry.
You must know that compared with cars and high-speed rail bullet trains, the plane is in the sky, and there is no protective measure for itself, once an accident is faced with a crash, everyone can only wait for death, on the other hand, the bullet train still has a certain hope of survival when driving on land.
Is it true that the danger factor of civil aviation aircraft is so high? If it is safest to take a civil aviation position? In addition, many people wonder, why not install a parachute on the plane, or equip each passenger with one?
Before that, we need to understand that in fact, airplanes are far less dangerous than we think, according to scientific data analysis and comparison, compared with cars, trains and other means of transportation, its accident rate is only one in a million.
That is to say, only one flight out of more than one million flights will crash, then some people may say, how can the probability be so low, there have been Malaysia Airlines MH370, China Eastern Airlines MU5735 and so on, these are all large-scale air crash disasters.
But you must know that there are more than 100,000 flights around the world every day, and there are only about 20 aircraft accidents in the history of civil aviation flights, and the accident rate is far lower than expected.
If there is a problem with your flight and an accident occurs, which position on the plane should you buy the best and safest?
Objectively speaking, there is no standard answer to this question, because there is not much chance of survival in a plane crash, it is the same everywhere, of course, this is not absolute, it still depends on the cause of the plane crash, the way it fell, and the height from the ground.
If you are lucky, the plane crash still has the ability to make a forced landing, the distance from the ground is not high, and the cabin door can be opened smoothly, so the position near the middle of the cabin door and the rear position of the passengers are relatively safe.
The reason for this is that when the aircraft makes an emergency landing, the nose of the aircraft is leaning forward, which is generally the first part of the impact, and it is very likely that there will be damage or even a devastating impact during the forced landing.
The person in the exit and tail position will naturally receive much less impact, but this will not reduce the damage much, because there is a high probability of fire and explosion after a crash and forced landing.
If the cabin door or emergency escape ladder cannot be opened, everyone will be burned to death or choked to death by thick smoke, and the overall survival rate is not high.
Then come to the next question, that is, how not to equip the plane and passengers with parachutes, first from the perspective of the aircraft, civil aircraft can weigh dozens of tons or even hundreds of tons, if the parachute is installed, how big it will be.
Not to mention whether it can withstand such a large weight, it is a big problem to make and install, and it is obviously not realistic.
For passengers, there are three major obstacles to being equipped with a parachute, the first of which is that all passengers do not have the experience and skills to skydive.
If you can't jump or don't have any methods and skills, then jumping out of the sky is tantamount to suicide, so this requires the person equipped with a skydiver to have enough experience in skydiving, otherwise the parachute will not be used, which is equivalent to useless work.
Secondly, from the installation point of view, this is also a big problem, if every passenger is equipped with a parachute, it needs to be installed in a certain place, and passengers can not be carried with a parachute all the way, which is too affecting the activity.
But the civil aircraft does not have so much spare space for installation, whether it is the cabin above and below the base does not have the conditions for installation, after all, this parachute is not a small object, it needs enough space, and the current civil aircraft does not meet these conditions.
Finally, from the perspective of the extravehicular environment, even the above problems can be well solved, but you must know that skydiving also has to have a suitable height and position, not to say that you want to jump, and the cabin door cannot be said to be open.
Ordinary civil airliners generally fly at an altitude of about 8,000 meters, and the gap between the inside and outside of the atmospheric pressure at this altitude is too large, and the cabin door is difficult to open.
Moreover, because of the atmospheric pressure, the temperature at high altitude is extremely low, up to minus twenty or thirty degrees, and the oxygen content is also low, which is not suitable for parachuting, and it is impossible to open the hatch casually to escape.
If the altitude is lowered, the time left for passenger evacuation and skydiving is greatly shortened, and even professional skydivers dare not guarantee that they can complete the entire process within three or two minutes in the case of high-speed landing, and successfully find a suitable place to lower.
In general, it is certainly unreasonable and unrealistic to equip aircraft passengers with parachutes, but we don't need to worry too much, with the development of aviation technology, the safety factor of aircraft is getting higher and higher, and there will be more safeguards in the future.
