Why aren’t civil aviation aircraft equipped with parachutes to allow passengers to parachute to survive in critical moments of air crashes?

This seems to be a problem that bothers many people.

Many people see reports of plane crashes. While feeling sad for the victims, they can’t help but have a question: How great would it be if everyone had a parachute? Wouldn’t everyone be saved? If the plane crashes, it can be rebuilt, but the loss of people is the biggest loss.

Yes, but every time a plane crashes in the sky, everyone puts on parachutes, jumps out of the hatch, and colorful canopies bloom in the sky, and everyone is saved. If the plane crashes, it crashes and can be rebuilt. The best thing is that people are saved.

People around the world can even watch a thrilling and wonderful performance through video, and then respond with warm applause. How wonderful.

But this is just a beautiful thought. Nothing in the world is that easy. First of all, skydiving is a technical activity and must undergo strict training before you can attempt it. Otherwise, even if you have an umbrella, you will lose your arms and legs and suffer heavy casualties.

Some tourism projects now include skydiving activities. People of all ages can jump as long as their bodies allow it. It seems that skydiving is not difficult.

But this jump is conditional. First, there is training before jumping; second, there are professionals to follow and guide all the time; third, professional skydiving aircraft are used; fourth, suitable climate conditions and altitude, and they will select an ideal skydiving place.

Is there such a requirement for taking a civil aviation flight? Does every passenger need to receive professional training? Will you choose the right altitude, temperature and meteorological conditions for skydiving? At the critical moment when something goes wrong on the plane, will everyone be assigned a professional to guide you in putting on your parachute bag and protective clothing, leading you to the designated skydiving hatch, and jumping one by one? Second, civil aircraft crashes are all emergencies, and it is difficult to leave time for parachuting.

Some accidents were able to survive due to the pilot’s efforts and control, while others disintegrated or crashed before responding. Is there time and opportunity for parachuting?

Even for a certain period of time, the plane was vibrating violently and even diving and rolling. Do these ordinary passengers have the ability to parachute under such conditions? Third, most civil aircraft crashes occur during takeoff and landing, and parachuting has altitude and time requirements.

In this low-altitude state, even professional skydivers have a narrow escape.

Only fighter pilots who have received strict training in flying and parachuting, with the support of high-tech ejection devices, can eject and parachute to escape. Do ordinary people have this ability? Fourth, the normal cruising altitude of civil aircraft is about 8,000 meters. The air pressure at this altitude is very low and there is severe lack of oxygen. Just like on Mount Everest, the temperature is dozens of degrees below zero.

Sitting in the airplane cabin, the plane automatically adjusts the air pressure and temperature, so it is very comfortable. As soon as you step out of the cabin, you will immediately suffocate to death and freeze into popsicles. In this state, even if you can parachute, you will die if you exit the hatch.

More than 5,000 meters, this height far exceeds the normal skydiving height. If passengers forcefully parachute at this time, they will face hypoxia, cold, high-speed airflow and other conditions when they exit the cabin. This will not save lives but will increase the mortality rate.

Professional skydivers are generally required to be at a height of 700 meters to 4,000 meters. A height of 7,000 meters is considered high-altitude skydiving. Very few people have such professional capabilities. Fifth, the special design of civil aircraft makes it difficult to open the cabin door when it is in a crash state.

If the plane crashes during takeoff and landing, the plane will be in a turbulent state in such a short moment, and it will not be able to respond by opening the door. And at an altitude of 8,000 meters, the pressure difference between the inside and outside of the plane is very large. Large ones, such as forced opening of the cabin, the people and objects in the aircraft will be sucked out of the cabin by the strong air pressure, and they will fly into the sky without jumping. When they are cold and suppressed, they will all die.

And the cabin doors of civil aircraft are not suitable for skydiving at all, only inflatable slides that can be opened in an emergency. Of course, if you really have the conditions to escape by parachuting in the future, you can redesign the skydiving door. This is a topic for later and will not be discussed here. Sixth, can the crew parachute and escape alive?

Some people think that pilots and crew members should be trained to parachute in emergencies, so as to keep people alive for accident investigation.

This is really a fantasy. If the pilot and crew can escape, if something goes wrong, they will escape first, leaving behind the passengers on the plane. Will anyone agree with this system? There was hope that things could be solved through hard work, but the person who solved them ran away and was left to die.

There was once a joke that a certain gentleman’s plane had an accident and was likely to crash. The flight attendant gave everyone paper and pen and asked them to write down their last words and then handed them to her. A crew member will parachute down with everyone's last words and deliver them to each family member.

Everyone was panicked, some were in pain and some fainted, but they still wrote short last words. The fault was later repaired, but the result was a false alarm.

This is completely a pretentious joke. With so many plane crashes around the world, has this ever been said?

If there really is such a flight attendant on the plane, who will this lucky guy be? What do other flight attendants think?

So this is all nonsense.

When a plane crashes, the greatest hope is only when all personnel work together. At this moment, no one can be left behind. To sum up, it is completely impossible to escape by parachuting after a civil aircraft crash.

Of course, we do not rule out the possibility of scientific development in the future. Each seat will be equipped as an ejection seat for a fighter jet. In the event of an emergency, you will be automatically ejected from the cabin, and you will be automatically protected and ejected. The umbrella cover allows you to land safely.

But if such conditions are really possible, why should we adopt this method of escape? Nowadays, there are many ideas on how to ensure the safety of aircraft passengers when there is a problem with the aircraft. Among them, there is a plan that the passenger compartment of the aircraft can be detached from the aircraft and landed with a parachute, which has aroused widespread discussion.

But someone said, what if something goes wrong with the crew cabin? This is too brain-burning, leave it to researchers to consider.

No matter what, civil aviation is still the safest means of transportation at present, and with the continuous improvement of science and technology, the guarantee of flight safety will become better and better.

That’s it, discussion is welcome, thank you for reading.
