China Eastern Airlines passenger plane had an accident, with a total of 132 passengers. What self-help measures should passengers take in the event of an accident?

Fasten your seat belt when boarding the plane. When the seat belt is loosened 1 cm, the impact on human body will increase by three times, so please fasten your seat belt! Secondly, listen to the conductor's command. Flight attendants have received professional training and know the correct escape methods. If there are flight attendants who stick to their seats after the accident, please follow their instructions and try to survive! Finally, curl your body before the impact to reduce the impact.

What if something happens to the plane?

Don't panic, wear an oxygen mask correctly. Glasses and dentures should be removed, sharp objects (including pens) packed in clothes and trouser pockets should be thrown into garbage bags, and women should take off high heels. If there is smoke in the cabin, try to keep your head down, hold your breath, soak towels and handkerchiefs with water or drinks, cover your nose and mouth before breathing, and then bend over or climb to the exit. Remember the direction of the engine room emergency door and its distance from yourself, remember the opening method, and imagine how to approach and open the emergency door as soon as possible in an emergency. When the plane makes an emergency landing, you should bend down, put your hands under your knees, put your head on your knees, and stretch your feet forward and get close to the ground. When the plane crashes into the sea, you should put on your life jacket immediately.

What should I pay attention to before boarding?

Loose clothes or clothes with too many accessories are not suitable for flying. Such clothes are easy to hang in the narrow space of the cabin. If the plane is going to cross a cold area, please put on more clothes and bring an extra jacket if necessary. The more clothes you wear, the less likely you are to be injured or burned in an accident. After boarding the plane, read the flight safety advice carefully and listen to the flight attendants to explain the safety issues. Don't think that safety advice is useless, or you don't understand it carefully by relying on your own knowledge. You will regret losing this important information. Different types of aircraft have different safety tips, so please understand the safety issues every time you board the plane. Passengers sitting in a row next to the escape door, please learn to open the escape door. Generally speaking, the flight attendant will open the door for the passengers, but if the flight attendant is injured or killed, the passengers must open the door themselves.

Why are civil aviation not equipped with parachutes?

Civil aircraft do not have the conditions for skydiving. Generally speaking, the altitude of skydiving is 500-1500m, while the interior of a civil airliner is isolated from the outside atmosphere, and the whole cabin is in a completely closed pressurized cabin. The air pressure in the engine room is much higher than that outside, so it is difficult to open the hatch. Even if someone has divine power and opens the hatch, the whole cabin will lose pressure immediately, and all passengers in the cabin will face cold, lack of oxygen and high-speed airflow. This kind of high-speed airflow will directly cause people to overturn and collide in the cabin, or be thrown out of the plane directly.
