Have you ever noticed the airplane window and noticed that she has little holes? Despite being very discreet, they play a very important role in the operation of the aircraft.
We know that the construction of an airplane is much more complex than we imagine and small details can solve big safety problems.

First, remember that air pressure is different when the plane is flying and the cabin is pressurized. Therefore, for the flight to take place properly, this pressure must be balanced between the outside and the inside of the aircraft.
Therefore, the structure of the aircraft had to be adapted to maintain comfort and security during the trip, even more with the circulation through different altitudes and climatic conditions.
Thus, the small hole is much more than an aesthetic issue or an aircraft defect, it was thought of as an engineering solution to maintain balanced lift and pressure.

The little holes in the window of the plane are called “pressurization windows” or “breathing valves”.
The windows of a aircraft it is made of acrylic, in addition, it has three layers of the material to be able to withstand and balance internal and external pressure. Usually, the hole is in the central layer and it is he who maintains the balance.
To the Brazilian Association of Airlines, Captain Raul Souza informed that the hole in the window of the plane is “an engineering mechanism designed for precaution. Whether in windows with or without the small hole, aviation has the safety of its passengers as a parameter”.
Thus, the holes are part of a complex aeronautical engineering project. Even the window is designed to withstand more than 30% of the difference in air pressure.
Therefore, for a window to break, a very high combination of force and speed must occur.
Definitely, even if you haven't noticed the little hole in the window of the aircraft, know that this mechanism is a guarantee of comfort and safety when traveling by plane.
