[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.

1. The difference between Luya pole and hand pole

1. Different definitions

Luya pole is a type of fishing rod. Luya originated from the interpretation of English, mainly composed of Luya pole, Luya wheel, fishing line, bionic bait.

Hand pole refers to the fishing rod without wound wheels. The length is generally 3 to 8 meters. Fishermen should usually consider the fishing waters and environment, as well as factors such as fishing methods and frequent fishing species.

2. Different classification

There are two types of straight handle and gun handle. The difference in the crossing ring is: straight handle generally uses a single -legged conductor, with a small number of small quantities and a large size.There are more sizes.

Handen poles are mainly divided into glass fiber Fishing rods and carbon fiber Fishing rods. Because the carbon fiber rod has the advantages of light weight, low vertical, high strength, wear resistance and corrosion, etc., it is loved by the majority of fishermen.

3. Different usage methods

The method of fishing fishing with roads is called bionic bait fishing method, also known as bait fishing, which is a method that imitates weak small creatures to cause big fish attacks. The artificially processed bidding bait imitates insects, fish and other movements in the water surface or water.Or the sound seduces the fish to bite or attack.

When fishing with hand poles, first observe the water feelings and observe the fish star. The fish star is a bubble in the breathing and foraging activities.It can show that the direction, type, size, and density of the fish can provide Yimi for fishing.Choose the fishing position. Generally speaking, spring fishing beach, summer fishing pond, autumn fishing yin, winter fishing, and then bait, accurate lifts, select the fishing position during fishing, wait for the fish to hook.

Second, novice fishing Luya or hand pole

For novices, the process of fishing is more troublesome. Preparing for appropriate tools will help improve the success rate of fishing.The fishing rod is one of the main tools to play during fishing.Novice choosing a fishing rod is also skillful and cannot be selected at will.Generally speaking, novice fishermen try to choose a fishing rod that is easy to use and easy to get started, and practice for a period of time.The hand pole meets this requirement, and there are many types of hand poles, and the effects are not bad.Novices can choose hand poles, and now the relatively small rivers or lakes practice for a while.

There are also many different types in the hand pole, and there are many problems to pay attention when specific choices.For example, for novices, the most commonly used length range is between 3.6 meters and 5.4 meters. You can choose the most suitable length according to the size of the fishing waters and personal habits.Quality is also very important. Although it is a novice, it is in the practice stage, but it is not possible to choose a fishing rod with too inferior quality, otherwise it is not easy to improve the technology of fishing.

Third, the novice fishing rod is good or the Luya pole is better

In addition to the hand pole is more suitable, there are also two kinds of Fishing rods that are also relatively famous, namely the rock and Luya pole.Compared with the two, it is generally more suitable.This is because the scope of the application of the rock Fishing rods is more widely used. They are not only suitable for large -area waters, but also for smaller waters.It is more suitable.

The Luya pole is different. Among the many types of Fishing rods, they are a relatively special rod, which can be used when fishermen use Luya fishing.Therefore, compared to the rock rods, their applicable occasions will be narrower, which is not suitable for novice use.Of course, if the novice fisherman wants to use Luya fishing to practice his hand, you can also choose Luya pole.Luya pole is designed for Luya fishing method, which is more targeted and suitable for use.

How to install and use the car GPS positioner
