Why do flight attendants ask passengers to open window panels when the plane lands?

I believe that for most people, whether they are taking a car, train or plane, they like to sit close to the window, because from the window they can not only see the scenery outside, the crowd that is gradually moving away, but also avoid friction with the aisle. But there is a small thing I don't know if you have noticed, that is, when you take off and land on the plane, there are always flight attendants who come to remind you and ask passengers to open the window blinds, do you know what the reason is?

I believe we all know that airplanes are one of the safest means of transportation, but there are times when airplanes have accidents, although this probability is 1 in 10,000, but not afraid of 10,000 is afraid of what happens, this small probability event should also attract everyone's attention. According to statistics, 60% of aircraft accidents and 30% of fatalities occur during take-off and landing, so for the safety of passengers, flight attendants will ask passengers to open the window shades when the plane takes off and lands.

There are three benefits to opening the visors of aircraft windows. First, the window visor can be opened to make it easier for passengers to know the direction of the aircraft, and in case of an emergency, it can facilitate passengers and flight attendants to respond quickly and accordingly. If an accident occurs, it will be more difficult to open the light shield, at this time the light shield will be stuck due to pressure, stuck points and other factors, so you need to open it in advance, if the cabin power supply system is paralyzed at this time, people can also escape in time with the help of the window, at the same time, passengers do not have to feel uncomfortable due to the sudden exposure of natural light, improve survivability.

The third and most important point is that for rescuers, it is extremely advantageous for rescuers to be able to observe the situation in the cabin, which greatly facilitates them to quickly make effective judgments, so as to carry out rescue in time. Of course, in addition to opening the sun visor of the window, there is also the need to put away the small table, straighten the back of the chair, turn off the electronic devices, and so on. So, on the plane, everyone must follow the arrangement.

Because the aircraft is the most dangerous time to take off and land compared to normal flight, opening the window panels can increase the escape power in the event of an accident.

Then there will be enough oxygen, if there is too little oxygen. It can make people feel deprived of oxygen, which is particularly uncomfortable, so the staff will do this, which is convenient for us.

When the plane lands, this operation is conducive to the smooth landing of the aircraft.

Many people pull down their visors as soon as they get on the plane and get ready for bed. But within a few minutes, the flight attendant will remind you that you need to lift the visor during take-off and landing.

The reason for opening the visor is that it is necessary to take precautions in case something unexpected happens. Aircraft accidents are usually concentrated in the minutes between take-off and landing.

Statistics show that more than 60% of air crashes or aircraft accidents in the world occur during takeoff, especially in the first 7 minutes. At this time, if the visor is opened, the impact is very large.

<> once an accident occurs, it will inevitably be accompanied by a strong impact, or a big turn, or even a rollover. If the visor is open, passengers can ** the next move of the aircraft and take protective measures to minimize the possibility of injury, especially to the head.

When an aircraft fails, its own lighting system will inevitably be affected until it is completely interrupted. If the visor is not opened, the cabin can be said to be completely dark. In this case, panic is inevitable.

Even if the plane turns out to be a false alarm, the passengers themselves could be killed or injured.

Opening the sun visor can provide lighting to help passengers judge the situation in the cabin and avoid panic. In the event of an accident, the airport's rescue team will rush to the scene of the accident as soon as possible. When the visor is opened, it can provide direction for rescue and take the most effective rescue method in the first place.

If the visor is closed and you can't see the situation inside, it will seriously delay the rescue time. Even dangerous situations, such as those caused by the cabin, go undetected.

For example, taking a plane in the United States is like taking a bus, find a seat in the cockpit, no matter how you like to sit, pull down the visor and listen to the sound headphones**, or sleep, or turn on to play games, there is you, there is no time for mom to tell you, please check that Mr. Tuke's headphones, such as turning on the visor, no one cares about you, as long as you don't open your eyes, until you land. There are more planes than China, there is no danger, to put it bluntly, it is civilian consumption, there are not so many broken things, maybe someone quarrels, so many lives, safety point is not a problem, it is not long before the mobile phone must be turned off in China? The previous one was not safe?

In the U.S., mobile phones don't need to be turned off since Nokia turned on airplane mode. How many planes have fallen because of cell phones? If the aircraft's avionics system can't even effectively shield the signal of the mobile phone, the operation cost of **** is too low, and even bother to look for a bomb, so that a few people can safely pass through the security check with an ordinary mobile phone and secretly put it in their bags to get on the plane.

Because there is air resistance, it can't be pulled if it is pulled inward, and the design of the aircraft is also like this.

"The board that covers the window should be a light shield. Generally, the visor does need to be opened when the aircraft takes off and lands, mainly for safety reasons. Airplanes are the most prone to accidents during take-off and landing, and it is safer at high altitudes.

For example, when the high-altitude engine is parked, the plane can also keep taxiing for a period of time, and when it lands, it can only make a hard landing. Therefore, the take-off and landing phases of the aircraft require extra attention. At this time, the cabin crew will generally ask passengers to open the light shield, put away the small table, and straighten the seat back, all for safety reasons.

This is mainly for the safety of passengers, preventing accidents and accidents.

The reason why passengers are asked to close the windows when the plane lands is because the landing process of the plane is a dangerous sport. During this process, the aircraft needs to vibrate violently, and in some cases, closing the windows can ensure safety and prevent windows from being damaged or window frames falling off, which can be extremely dangerous to passengers and crew. In addition to this, closing the windows can also increase the pressure inside the cabin, ensuring the flow of air inside the cabin.

In addition, closing windows can also reduce the effects of noise and temperature. As the altitude of the aircraft changes, the flight speed decreases, and at the same time, the temperature and pressure also change. If these changes are ignored, the aircraft's windows may break, causing them to fall off or be blown open by strong winds, potentially damaging other components or affecting passenger and crew comfort.

In addition, closing windows and keeping an eye on the feast can help keep passengers comfortable. When the windows are open, the impact of the external environment on the passenger may be more pronounced, such as stronger light and stronger winds. Closing windows can mitigate these effects, making it easier for passengers to fall asleep or rest more comfortably.

The landing process of an aircraft is a very complex and dangerous task. Closing windows ensures the safety of passengers and crew and avoids windows cracking or being blown open by strong winds. In addition to this, closing windows can also reduce the effects of noise and temperature and improve passenger comfort. <>

Hello, I am a flight attendant of Air China.

When the flight takes off and lands, it is mainly to prevent accidents, and there is a saying in international civil aviation that the 6 minutes after take-off and 7 minutes after landing are called "black thirteen points", because it is very prone to danger during this period. Of course, the crash rate of the airliner is 1 in 10 million, which is still quite safe.

However, in order to prevent accidents, we ask passengers in the cabin to put away the small table, adjust the seat to the normal position, and fasten the seat belt. The light shields on the windows, and the foot pedals of first-class passengers are all designed to be able to evacuate and evacuate in case of escape. The lights in the aircraft are turned on during the day, in order to save energy and for safety.

Lights are turned off during night flights to make it easier for passengers in the cabin to rest. However, there are also cases where CA991 flies to Vancouver and flies at night for two hours after level flight, so that passengers can rest and prepare for jet lag in advance.

Because when the plane takes off and lands, it is the most wreckable time in the whole flight, the attendant will ask the guest to open the sun visor and dim the lights in the cabin. The main purpose is to allow guests to get used to the brightness outside the plane, and if an accident really happens, the eyes can immediately adjust to the brightness of the light outside and escape the scene.

Because when a person goes from a place of light to a place where there is no light, it must take a few seconds for the eyes to adjust, and in the process, they will not see anything for a while. And there is another effect, because the plane is very large, the pilot cannot see the engine in the cockpit, at this time, if there is a guest who sees the engine abnormal, he can inform the staff in time.

For safety, when taking off and descending, especially when the ground is slippery, it is more likely that there will be a power outage in the cabin, once the power is off, if the visor is not opened, the cabin will be pitch black, easy to cause riots, which is not allowed. So it must be turned on when taking off and landing. When flying level, pull down the light shield, there is no natural light outside, only the soft light of the cabin, whether it is watching movies or sleeping, it is very comfortable, especially in 777 for business or first class.

Open the light shield during take-off and landing, this is so that you can observe what is abnormal outside the window, you can notify the flight attendant in time, and the second point is that if you fail to leave the plane in time after an emergency landing, you can also get timely help from the rescue personnel, who will see you through this window.

That's called "visor", not "window".

The purpose of opening the visor when the aircraft takes off and lands is for safety. When taking off and descending (especially when the plane is taxiing on the ground), it is more likely to have a power outage in the cabin, once the power is out and the visor is not opened, the cabin will be pitch black, which is easy to cause riots among passengers, which is not allowed! Therefore, the visor must be opened when taking off and landing.

After the plane takes off, when the light shield is pulled down when it flies at level, there is no natural light outside, only soft light in the cabin, whether it is watching a movie or sleeping, it will be more comfortable.

Another function of the light shield to be opened when the aircraft takes off and lands is to allow you to observe anything unusual outside the window and notify the flight attendant in time. In the event of an emergency landing, if you fail to get off the plane in time, you can also get timely help from the rescuers (they will see you through this window).

Why do planes have to open windows for take-off and landing? Listening to the professional people, I have increased my knowledge.

Balance the atmospheric pressure inside and outside the aircraft.

Passengers are asked to open window blinds before take-off and before landing for safety.

Aviation safety studies show that about 90% of all flight accidents occur in the first two minutes or the last four minutes, if an accident occurs during take-off or landing, the aircraft has a power outage, the lights in the cabin are turned off, the lighting is not enough, open the window visor to let the outside light shine in, which helps passengers to see the internal structure of the passenger aircraft, their own location, passage, emergency exit, etc. At the same time, rescuers outside the passenger aircraft can also observe the interior of the aircraft through the sun visor when they cannot enter the interior of the passenger aircraft in time. Plus, it's easier for you to see what's going on outside.

Another goal is to try to be as consistent as possible with the outside light, so that if the passenger needs to escape quickly, the eyes do not need to adjust the difference between the inside and outside light.

Open the sun visor is to take into account the safety needs, because in the take-off and landing stage, the danger factor is relatively large, if there is a take-off and landing mistake, it is very likely that there will be an emergency evacuation and external personnel to implement emergency rescue for the personnel in the aircraft, open the sun visor can be convenient for the personnel in the aircraft to observe the external situation, for example: when the aircraft is on fire outside, it can be observed in time through the window, then when the emergency evacuation and evacuation of passengers is done, the affected emergency exit can be avoided, and the side will cause greater damage, At the same time, when external personnel carry out emergency rescue, they can also easily observe the situation in the aircraft in order to decide what kind of emergency rescue to take.

It is an international practice to open the visor during take-off and landing, and each airline requires all passengers to comply with it.
