airplane never noticed a little hole in the window! If you look like this, it will be frightening. But no, experts say this hole has a very important role. First of all, it may seem bizarre to you. When there is an airplane flying in the sky with so many people, why the little hole in his window!
The Federal Aviation Administration spoke on behalf of Tech Insider. They said that those holes were put in place to bring balance in air and outside air pressure. The air pressure is much lower when compared to its inner air pressure, when the aircraft gets elevated. There is a great deal of pressure on the aircraft's window for this difference between internal and external pressure.
So three-level glass is placed on the window. There is very little space between the pressure of the middle level glass pan and the outer layer glass pan. And the hole is in the middle level pananei. Through this, the balance of air and air air pressure is maintained. The air pressure in the air pane in the air layer of the window. If the external level fails to balance the pressure, then the middle level works to maintain safe pressure.
