When we get on board the plane for the first time, we can feel a bit lost among various markings and sounds. Some of them may seem disturbing, but they all have their logical explanation and serve to ensure safety and comfort of travel. Let’s take a closer look at what is happening during the flight and find out that the devil is not as terrible as they paint him.
What does a triangle on the plane mean? The black symbol reveals these places
Did you find a black triangle above your window on the plane? Congratulations, you came across a place with the best view. As the Henna Lim Stevardes revealed, which is divided by their knowledge on Tiktoku, passengers sitting at these stamps have a perfect observation point to admire, among others flaps on the wings. These are the moving elements that help the plane get into the air and land. So if you are passionate about aviation and you want to admire the views of the bird’s eye view, the black triangle is a sign that you have chosen the perfect place.
What about small holes in the windows? Relax, they also have their important task. These miniature holes help in leveling the pressure between the interior of the aircraft and the space outside. In addition, they get rid of moisture, which could settle on the windows and hinder the view.
What do two bells on the plane mean? The sound signals have an important function
Sometimes single, sometimes double, sometimes loud, once quieter “picni” – mysterious sounds on aircraft have long been bothering the heads of many passengers. However, you don’t have to worry, most of them are not alarming. Most often we hear them right after the start, about 5 minutes after the machine detached from the ground. Two characteristic bells mean that we have reached a through height – 10,000 feet, or about 3050 meters. This is a sign that we can detach the belts and finally go to the toilet.
We will hear a similar signal 5 minutes before landing. Two loud bells mean that the plane went below the height and the crew begins preparation for landing. What about the rest of the sounds? These are more subtle “codes”, often combinations of high and low tones. We will hear them when the crew uses the on -board communication system. This is their way to provide various information – from minor arrangements to more complex messages. There is no reason to worry in any of these cases.
