On the plane, you often hear the stewardess remind the passengers' please fasten your seat belt when you are seated ',' the plane is about to take off, please confirm that your seat belt is fastened ',' please fasten your seat belt when the plane is bumpy '. Why fasten the seat belt? Do you use the seat belt correctly? Let's talk about the knowledge about the aircraft seat belt.
What is an airplane seat belt?
The purpose of aircraft safety belt is to restrain the passengers in the collision and to avoid the secondary collision between the passengers and the seat or the aircraft, or to avoid the death and injury caused by rushing out of the seat in the collision.
Why do you use aircraft seat belts?
When an aircraft is flying at high altitude, it is not only affected by the environmental factors, but also sometimes by the adverse factors in the movement of the aircraft itself. The main performance is the passive displacement of human body caused by the change of acceleration and the violent turbulence caused by the complex climate. The strong turbulence of up and down rotation will throw unbelted passengers to the top of the cabin and then to the seat or floor. The danger can be imagined. In flight, the aircraft is suddenly affected by thrust or resistance, which changes its speed or direction, and then produces acceleration. When taking off, landing and sharp turning, human body displacement will be affected by the change of acceleration.
For example, if the landing speed of the aircraft is too high, if the passenger fails to fasten the seat belt, then the aircraft slows down suddenly, the passenger may suffer from collision damage due to forward leaning. When the aircraft makes a sharp turn, due to the large centripetal acceleration, unrestrained passengers are easy to tip out.
Safety belt is a necessary preventive measure. When the aircraft stops in an emergency or encounters strong turbulence in the process of takeoff and landing, the passengers who are not wearing the safety belt often fail to take precautions and suffer accidental injuries. This situation is not uncommon at home and abroad. According to the investigation, many passengers on this SIA flight are safe because they are wearing the safety belt, while those who are not wearing the safety belt are safe In the face of sudden changes, passengers are injured to varying degrees, so it can be seen that the role of seat belts cannot be underestimated.
When do I need to buckle up my seat belt?
At the simplest, each seat can easily see the indicator light of "please fasten the seat belt". When the indicator light is on, fasten the seat belt, usually including the following situations:
During ground taxiing, passengers should also fasten their seat belts. On the ground, the aircraft will turn and brake due to avoidance of aircraft or obstacles. At the same time, when complying with the order of aviation control, the taxiing direction of the aircraft will be changed suddenly, which requires the use of seat belts.
In the air, when the aircraft encounters turbulence in flight, it will vibrate, throw up and down, shake left and right, resulting in difficult control, inaccurate instruments and other phenomena. Some bumps can't be foreseen, so we should get into the habit of wearing seat belts when we take seats on the plane. Especially when the seat belt light is on, fasten the seat belt as soon as possible to avoid accidents.
Descent is the key stage of flight. Don't forget to check whether the safety belt is fastened properly and increase safety guarantee.
Correct fastening and unfastening method of aircraft safety belt
After getting on the plane, the first thing you need to do is to find the right way to fasten and unfasten the seat belt. When you enter the cabin and sit on the passenger seat, use both hands to pick up the safety belt from both sides, and put the end without metal fastener through the metal fastener along the groove and hole, just like people usually bolt the belt. Hold the metal fastener with one hand, and hold the webbing with the other hand until it is tightened. Do not leave a gap. Move the upper body and buttocks to make them close to the back of the chair, and pull the safety belt to fasten it. In terms of feeling, it should not be tightened or loosened. You should also learn to untie it quickly and fasten it skillfully. When undoing, let the abdomen contract a little. Hold the release device with one hand, and push the release buckle with the other hand, and the safety belt will be released immediately.
If you are not sure, don't be embarrassed to ask the stewardess, because if there is a forced landing, it is an important factor for survival. First, make sure that the buckle is facing up when you fasten the safety belt after you take your seat. If you buckle your seatbelt upside down, you will be more unable to find the buckle due to panic after an emergency.
Secondly, try to reduce the barrier of goods. If you want to use a blanket, try to tie it inside the seatbelt so that you can find the location of the buckle immediately. At the same time, remember how to use it. The safety belt is to open the buckle and pull out the insert. It must not be confused with the car press type buckle. In addition, remind you that the seat belt should be fastened low and tight to work.
To sum up, we should pay special attention to the safety requirements of flight attendants, and at the same time, don't forget to check whether your safety belt is fastened, which will increase your safety guarantee and protect your safe and stable arrival at the destination.
