The captain of the plane crash chose why not let the passengers parachute?The considerations behind the life-and-death decision
Zhuangzi - Autumn Water reads:"Now I move my heavenly machine, but I don't know why I move"。That's what we often say"I only know what it is, but I don't know why"："I only know what it is, but I don't know why"。
We can only see the appearance of many things, but we cannot see their essence and connotation. Taking last year's TV blockbuster "Chinese Captain" as an example, many people can't help but ask, why didn't passengers parachute when the plane crashed?
As a widely used means of transportation for modern people, the advantage of airplanes is that they are comfortable and fast, and the disadvantage is that they are far away from the ground, and in the event of an accident, the chance of survival is almost zero.
Some still don't understand why, in the event of an accident, the captain would decide to let the plane crash instead of providing a parachute escape to the passengers. The person who asked this question should know about Wenchuan**"An incredible leap"。
Although skydiving may seem simple, it is impossible for the average person and requires a high level of professional skill to perform successfully. You know, skydivers without exception have undergone professional skydiving training, and each of them has undergone rigorous professional training and has an extremely high level of skydiving knowledge.
For example, after the Wenchuan Da** incident, 15 skydivers, each of whom has undergone professional training, can not be compared with others in terms of physical and psychological characteristics, but they still regard death as home. As you can see, skydiving is not for everyone.
The passengers are ordinary people, they have not undergone professional training, and many of them have not even touched a parachute, so it is obviously nonsense for ordinary people to quickly and accurately complete the action of opening and lowering the parachute in a short time.
Assuming everyone on the plane has a parachute, but the time from the accident to the end may be less than a minute, can hundreds of passengers leave the plane in an orderly manner during these few minutes?First of all, the passengers do not have enough skills;Second, when danger comes, the average person's emergency response ability is static, and they are more likely to scream in a panic. Therefore, for various reasons, even if the aircraft encounters danger at high altitude, passengers can only leave their safety to the captain alone.
In addition, it is obviously impossible to provide professional skydiving training for everyone because the cost is too high. It is also impossible for aviation authorities to provide special parachutes for passengers who only stay on the plane for a few hours, because the cost is too high. Secondly, the tacit cooperation between passengers. In the face of danger, it is necessary to cooperate with each other, which is obviously impossible between strangers.
Looking at the plane itself, there are only two doors in the cabin, and even if both doors are open, it is impossible to disembark a few hundred passengers in a minute. Secondly, the plane has climbed to a great height, and there will be a huge pressure difference between the cabin and the outside world. If the cabin door is opened in a hurry, the huge pressure difference between the inside and outside of the cabin can suck passengers out of the cabin, and in this case, there can really be a loss of life.
From the point of view of the load capacity of the aircraft, the load capacity of the aircraft is limited, each aircraft has to carry something every flight, such as passengers, passenger luggage, crew, crew luggage, food, drinking water, etc., if each passenger prepares an additional parachute, that is, the weight of hundreds of parachutes will be added, which will undoubtedly affect the load capacity of the aircraft, and the risk factor of the aircraft will also increase. This will undoubtedly increase the weight of the aircraft and increase the risk factor of the aircraft.
In general, the probability of a plane crash is minimal, and even if there are a few plane crashes, most of them are due to the failure of the environment or the aircraft itself. In such dangerous situations, the aircraft usually flies at low altitudes. As we all know, skydiving also requires a high flight speed, which cannot meet the special skill requirements required for skydiving. Insufficient altitude during a sudden skydive can also increase losses.
In short, no matter what the flight environment of the aircraft is, such as the flight altitude, the air pressure inside and outside the aircraft, the flight altitude of the aircraft, etc., ordinary people should not perform such a difficult behavior as parachuting.
Although skydiving is a survival tool, the use of any tool requires professional training to achieve, and reckless behavior will only increase the danger, increase the stress of the crew, and increase the difficulty of forced landing. The basic tenets of Marxism tell us'Science and technology are the primary productive forces'So we can hope for the future, maybe in the near future, with the development of science and technology, reduce or eliminate the occurrence of air accidents, we don't have to worry about the occurrence of air crashes.
