Planes don’t have parachutes for a variety of reasons, mainly because parachuting isn’t the best way for passengers to survive an emergency.
In comparison, life jackets are more practical.
1. The cabin of the passenger plane is sealed. If the door is opened, it will lead to a serious loss of pressure accident, and the consequence is that all passengers in the cabin will freeze to death or suffocate to death.
At the same time, right next to the door is the engine, and passengers could easily get sucked into the engine after parachuting.
2. Plane crashes usually happen in an instant, and even if each passenger has a parachute, there is no time to put on the parachute to complete the jump, and then jump off one by one.
3. Skydiving looks simple, but it’s actually a skill that requires special training.
An untrained man, unable to operate a parachute, could easily wrap himself in the parachute and smash himself like a stone to the ground, breaking persimmon.
4. The price of parachutes is expensive, which is not small economic cost for airlines.
5. If each passenger is equipped with a parachute, it will greatly increase the weight of the aircraft, and it will take up a lot of space, greatly affecting the ability of the aircraft to operate.
The inflatable life jacket for aviation is designed to achieve the purpose of life saving by pulling the rope on the inflatable device to turn the rod to not less than 90 degrees, puncturing the diaphragm in the high-pressure gas storage cylinder (disposable, replaceable) with the needle, and punching the high-pressure carbon dioxide gas into the air bag, generating buoyancy after the gas expands.
The inflatable life jacket consists of a sealed inflatable bag, a miniature high-pressure gas cylinder and a quick inflator valve. It is often used in jobs where there is a possibility of falling into the water.
Under normal circumstances (uninflated), the entire inflatable life jacket is worn like a ribbon, hanging over the shoulder and back, and does not hinder people’s freedom of operation due to its small size.
Once fell into the water, the emergency of danger need buoyancy in the water, according to the role of water automatic inflatable (automatic air jacket), or use the hand to pull the cable on the charging valve (manual air jacket), will be completed in 5 seconds inflatable produces 8 to 15 kg buoyancy, lift up the human body, make them carelessly head and shoulders above the water,
Timely access to safety protection.
