Why open the window when the plane takes off and landed?

During a flight, when the plane is about to take off or land, the crew will ask the other passenger to pull all the curtains on both sides of the plane. Have you ever wondered, why should you do that?

The answer is simple, for safety reasons. This action is simple but very important and is part of aviation safety procedures applied to all major commercial aircraft.

The time of aircraft takeoff and landing is very important, the most likely to happen. If there are any emergency incidents, the crew only has 90 seconds to evacuate all passengers on the plane, in small or large numbers. This time, fast or slow for a second is also very important, so the crew must prepare all possible situations, one of which is to ask the passenger to pull up the window curtain.

In an emergency, the crew needs to quickly determine which plane location is the safest to open the exit door. Time is very important now, the window screens are pulled up to make it happen faster.
Passengers are very curious and often look outside through the airplane window. So if you pull the window blinds up, they can help the crew detect unusual incidents outside the plane such as signs of damage on wings, strange objects, .

For daytime flights, window blinds and lights are maximized to help passengers get used to the light. In the event of an emergency, their eyes will not be affected by sudden light changes.

With night flights, the window screen pulls up to help ground rescue workers observe what happens inside the plane.

When the plane took off and landed, in addition to pulling up the window curtain, passengers were also asked to fold the table and erect the seat so that if something went wrong, the evacuation was done quickly. When you are passengers sitting on the plane, please follow the requirements of the crew to ensure the safety of the goods.
