All aircraft windows are always closed in modern passenger jets. I think you mean the window shades.
They usually close the window shades in order to cut out the lights from outside even at night. Also for international flights, the aircraft can fly into daylight while the passengers are still sleeping during the time that is night for them. So if only the lights were turned down and everyone went to sleep then when the sun came up it would wake most of them before it was time to land.
at night when there is wind
Why are airplane windows curved? A: This Q is about windows that are NOT flat. Usually curved windows are designed to fit the shape of the airplane so as make the airplane more aerodynamic and not be boxy. Why are airplane windows rounded on the corners? A: One of the first British jets began to crash for no reason. This airplane, the Comet, had large square windows. The investigation discovered that the airplane cracked open at the corners of the windows. This was about the time that engineers began to understand the phenomna of Fatigue. Their tests showed that the corners of the windows resulted in higher stresses and it fatigued the metal. They redeisgned the windows to be rounded and it reduced the stresses and no more planes crashed. Sharp corners in holes of any surface that is carrying a load will increase the stresses. If the corner is changed to a curved edge, then the stresses are lowered. Think of stress as a flow of forces and when it comes to a sharp corner, the flow can't go around the corner.
lower your thermostat a degree or 2 and make sure all doors and windows are closed. also keep drapes open in sunny rooms until night time then close them
The world condition at night varies depending on the time zone and location. Generally, at night, most people are asleep, businesses are closed, and there is less activity compared to daytime.
They closed whenever they wished.
On the contrary, they must be open. It's because, if an engine fails, the pilots won't know until something really bad happens, and in that case they've wasted a lot of time. This way, the flight attendants can see the engines and tell the pilots if anything happens.
The Who were the last to perform on Saturday, before the Jefferson Airplane took the stage on Sunday morning. The Who had played through the night, into the dawn. Then it was time to sleep for a few hours, with the Airplane taking the stage at...maybe about 10 AM?
It is not safe to stay in a car with the windows closed for an extended period of time, as the air inside can become dangerous within minutes due to lack of ventilation. It is recommended to open the windows or turn on the air conditioning to ensure proper airflow.
yes In the case of a weak tornado a closed window can prevent damaging winds form entering the house. Though if a tornado is coming do not waste time with the windows. Take cover immediately.
A blackout Curtain is somethig a government may order the people of it's country to put in their windows during a time of war. They are black and thick they are closed at night so that no light will shine through, this way if an enemy aircraft were to fly over and all the homes had these curtains up and closed they wouln't be able to see the contry or islands.
More people are out during the day because of work, school, and shopping. Schools and most businesses are closed at night, so there is less traffic at night.
