Why do you have to roll up the airplane windows when taking off?

Air travel, especially when taking off and landing, requires a series of security measures that the crew remembers on each trip. We are talking about fastening the seat belt, closing the tray correctly, placing your bag or backpack under the seat or knowing the exact location of the life jacket. However, hostesses also tend to take care of a number of details that sometimes go unnoticed for most passengers, for example, that the windows are always open during arrival or departure from the airport. What is the reason?

It is not mandatory, but it is recommended

Although most airlines «force» you to roll up the windows before taking off or landing on the runway, the truth is that it is an unwritten law and each company decides whether to apply it or not. However, the reasons behind it make perfect sense.

This practice is closely linked to another that also tends to occur on most flights and which consists of dim the lights inside the plane, especially if it is a night journey. The combination of both guidelines is a security measure in the case of facing an impromptu accident or emergency landing.

Looking out the airplane window

Rolling up the windows and turning off the lights ensures that, if an evacuation is necessary, rescue teams could better visualize the interior of the ship, thus confirming the status of the passengers and crew, as well as the condition of the plane.

Likewise, these measures would also help the crew to know the exterior to determine which emergency exit is more convenient to use, thus avoiding possible obstacles, fire zones or steeper falls. As for the lights, some experts also point to the ease of passengers to adapt to the lack of light that may be outside if a night evacuation takes place, which would increase the speed when leaving the plane. Therefore, from now on, strictly follow all the advice of the crew, even if you do not know the reasons for it, they could save your life.
