[The role of life jacket] What is the use of aircraft life jackets for aircraft life jackets?

What are the use of aircraft life jackets

When it comes to life jackets, many passengers will think of evacuation at sea.But some passengers have questioned: Why do inland routes still need to be equipped with life jackets?That's because the plane may fly over the river and lake during the flight. If it is necessary to surrender at this time, it is likely to be forced to land on the river or lake, and naturally you need a life jacket.

The life jackets on the plane are divided into two types: red and yellow.The red life jacket is used, and the yellow life jacket is used for passengers.Even if the plane is not forced to land on the water, when the remote land from the airport is forced to land and evacuate, wearing a life jacket can make passengers more conspicuous in the open area, so that rescuers can be found in time, and in areas where low temperatures, strong winds and ice coversIt can also play a role in protecting the cold.

The life jacket is mainly made of nylon materials. There are two airbags up and down. There are two small high -pressure gas cylinders between the airbags distributed on the left and right sides of the life jacket.There are two red inflatable handles on the lower side of the life jacket to pull the red inflatable handle, and the life jacket can automatically inflatable.

There are also artificial gas pipes on both sides on the upper side of the life jacket. This is a unidirectional door similar to the bicycle valve core.When the life jacket is insufficient or leaking, pull out the artificial inflatable pipe, and you can inflatable with your mouth.When holding the top of the artificial inflatable pipe by hand, the gas will be released from the life jacket.There are positioning Lights on the top of the life jacket.It is powered by the seawater battery. After the seawater battery is soaked in water, the positioning light will automatically emit light within a few seconds, and it can continue to use it for 8 hours to 10 hours, which is convenient for the water drop -off to be found at night.

The life -saving jacket is divided into two types: baby life jacket and adult life jacket, which are stored in different positions.First -class and official class passenger life jackets are generally stored under the armrest armrests; ordinary cabin passenger life jackets are placed under the seat, and they can be touched by lowering their heads. Infant life jackets are generally placed under the first row of baby cradle seats in the cabin.Children under the age of age need to use baby life jackets, while children over the age of age can use adult life jackets.

precautions for the use of aircraft life jackets

According to airline staff, the life jacket should be inflated before leaving the plane and before boarding the Ship.This is because the life jacket will be bloated after pumping, and passengers can easily crowd the aisle and exit when they evacuate, which affects the evacuation time.And the inflatable life jacket is easily cut and leaked by sharp items, losing life -saving function.In addition, if the aircraft gets in water, the life jacket will make passengers drift in the cabin, and even pushes even on the cabin ceiling, which is difficult to escape.

When the plane is forced at sea, passengers should not try to swim in life jackets unless they need.Because the temperature of the water and water is low, the average surface water temperature does not exceed 20 degrees Celsius, and the temperature of 13%of the water meter temperature is less than 4 degrees Celsius. Adults in thin clothes survive in the water temperature of 10 degrees Celsius for about 2 hours to 4 hours.Cold water should be reduced as much as possible to save energy.

It is worth noting that parents and passengers should pay attention to the life jacket they wear when they are hugged. The life clothes of the mother and baby should be tied together.For children, only half of the breath of the life jacket you wear after leaving the seat (pull a inflatable handle).In terms of methods, life jackets should be worn on the outermost clothes.

Emergency life jacket treats nature with an attitude of conquest. You can never conquer nature. Human beings are very small under the power of nature. There will be in case of the situation at any time.use.Of course, there are also many emergency life -saving equipment that can be used in one thing, and can also achieve the purpose of the least equipment to do the most.

The life -saving equipment on the plane is mainly a life jacket for passengers.There are two colors of life jackets: yellow and red.Among them, red for the crew of the crew, yellow is used for passengers.Both colors are warned, making rescuers easily discover and distinguish in the vast sea.The life jacket is made of nylon materials into two airbags, which plays a role in dual insurance.There are two high -pressure gas cylinders in the attachment. 2 Automatically inflatable in seconds; the mouth blowing pipes on both sides can be artificially inflated to increase the buoyancy.The power supply of the position indicator is activated by the seawater, and the power supply time can grow up 12 For more than hours, it is easily found at night.Some are also equipped with whistle (for calling), mirrors (reflected light) and so on.

Emergency life jacket - Anti -theft system

Emergency life jacket 1999 Year 7 From the beginning of the month, China Eastern took the lead in using the aircraft life jacket anti -theft system, which will greatly control theft.Anti -theft system 5 Part of the composition: power component, launch antenna, controllers, tester and target blocks.Among them, the launch antenna is installed near the passenger import and exit door, and the signal range can be adjusted.When the plane landed, the flight attendant opened the controller (prohibited during flight) into the working shape. Once someone was good at taking the life jacket and brought it into the door, the signal range could be adjusted.When the plane landed, the flight attendant opened the controller (prohibited use during flight) to enter the working state. When someone was good at taking the life of a life jacket and brought it into the antenna emitting signal at the door of the cabin, the controller would make alarm sound, and at the same time, at the same time, at the same timeThe target block installed in the life jacket will also make alarm sound.When the stolen life jacket leaves the range of the antenna signal, the controller stops issuing alarm, but the target block will still make alarm sound to take action.The role of a hand tester is to eliminate the alarm and the target blocks used to remove the life jacket.This kind of anti -theft system is like a "bodyguard", always guarding the life jacket, and it will become more and more active.

What is water skiing

Water skiing is the same as its name, which is to glide on the water surface.However, the water skiing movement requires external forces, which means that the water skiing athletes walk on the water surface on the sled with the help of external motivation to walk on the water surface.

What equipment needs to prepare water skating

1. Traction equipment

Water -skiing traction equipment is usually divided into two types, one is the Tow Boats, which is professional to become a water skiing hug, and the other is Cable.The most commonly used in the world is water skating and trailers.Trarters are generally manufactured by professional water skating rug manufacturing companies. Generally, horsepower is about 300 horsepower. The boat design is very in line with the need for water -skirakrs for tail waves (professional -called tail flow).Water skiing rug is relatively expensive. The price of a tugboat is usually more than 40,000 US dollars, which is a Mercedes of a small motor boat.Soon after the ropeway traction equipment appeared, it was similar to the high mountain ropeway, but it only surrounded the mountain ropeway into a closed venue, and a special inverter device was added to the ropeway, allowing the traction speed from more than 20 kilometers/h to 60 kilometers/h.The biggest benefit of traction equipment is that it can be erected in a small waters in the center of the city, but the one -time investment is large.

2. Waterboarding board

There are many types of water -skiing plates (professional names of water sips). Each sled represents a type of water skiing. It is generally used in jumping sidelines, rejuvenation, lags, tail -sleds, Kneeling boards, and so on.

3, warm clothes

Water -skiing people generally have several purposes wearing warm clothes. One is that water can slide at low water temperature, and on the other hand, the warm clothes are made of synthetic materials such as sponges, rubber.When you accidentally fall into the water, you can help the water -skiper surface.In addition, the design of the new -style warm clothes is very beautiful, like a special Swimsuit, which makes people look "cool".Some girls use it to avoid the sunlight.

4,life jacket

For safety considerations, several projects of water skating require water skiing people to wear life jackets such as jumping and rotation.For those who are new to water skiing, wearing life jackets are almost mandatory.Due to the buoyancy of life jackets, water skiing people can float in the water without drowning.

5. Water skiing and drag rope

Water skating rope is generally woven from glass silk. The diameter is generally about 1 cm. Generally, it can withstand more than thousands of kilograms of tension without deformation or broken.The length of the drag rope varies depending on the water skiing project.The skating rope is generally 23 meters or 31 meters, and sometimes it changes according to the characteristics of the competition or performance.The jumping tape rope is 21.5 meters long, and the label rope is 16.75 meters long.There is no restriction on the length of the rope.During the jumping competition, the prescribed length of the towing rope is 23 meters; the length of the drag rope of the rotation competition is continuously referee by the athlete's game process and continuously by the referee according to the 18 -meter 25, 16 meters 25, 13 meters, 12 meters 25, 11 meters 25, 25 meters 25 25, 11 meters 25, 11 meters 25, 11 meters 25, 11 meters 25, 11 meters.The order of 10 meters 75, 10 meters 25, 9 meters 75 is shortened; while the pattern and tail wave competition can be chosen by the athletes based on their personal habits, but it is generally about 20 meters.

6. Pull the handle

Water slide puts the handle of the dragg rope held by the water -skisting person. The shape is similar to a triangle. There is a ring cover that can be connected to the dragging rope at the top.EssenceThe handle is generally buoyant, and it will float on the water even if it falls into the water.

7. Others

Water sliding gloves, arm rings, water skiing shorts, paddles, life rings, oxygen Bags, nylon vests, etc. are also equipment often used by water -skious people.

Benefits of Water sports

As a more exciting exercise, the first benefit of the water skiing movement is that it can bring you a sensory stimulus experience during the movement.At the same time, you can make you feel new.Because water skating is an outdoor sports, you can also enjoy the infinite warmth of the Outdoor blue sky and blue water and to exercise your body well.In addition, because water skating has traction, it will have a certain sense of security for people with less courage.
