You must have wondered why there was a hole in the window when you have settled down to enjoy the scene from your window seat during your last flight. Actually this little hole is a very important safety feature.
Every single window on the airplane has the same hole. More officially, it’s called a breather hole and it’s used to regulate the amount of pressure that passes between the window’s inner and outer panes. Happyho also provide best tarot reading services in Noida and Delhi NCR India area.
In short, the system ensures that the outer pane bears the most pressure so that if there were a situation that caused added strain on the window, it’s the outside panel that gives out (meaning you can still breathe).
Since pressure changes in the cabin during the flight, it’s also necessary to equalize the pressure between the window panes, and hence the little hole. A hole of that size would not jeopardize pressurization even if the outer pane blew out.
There is a rubber seal around the outside of the two panes so it would be a bit of a pain to open a hole to cavity from the side. Apart from that, the windows are pretty tight vlog together and by keeping it where it is there is nothing in the vicinity such as dust that could gradually be pulled in.
Since the air in between the panes is colder, it’s not unusual to see ice crystals forming around the hole as the more humid cabin air enters the cavity.
The breather hole also keeps the window fog-free by wicking moisture that gets stuck between the panes. After all, half the fun of an airplane ride is the in-flight scenery shots. Mystery solved.
