There are many details about the plane, its purpose, and even its existence of which the passengers have no idea. Some of these functions were revealed by aviation workers.
The secret armrest button can be useful for tourists. On some aircraft, the armrest next to the aisle may appear to be fully fixed.
“But if you look under the armrest, closer to your back, you will find a button that will allow you to move the armrest so that it is flush with your seatback. This will give you extra space and make it easier to leave your seat during the flight.” experts write.
Some tourists wondered what was marked by the innocuous-looking black triangle above the portholes somewhere in the middle of the liner.
“The easiest way to check the wing in flight is to simply look out the window. The black triangle marks the place where the clearest view of the wing opens,” the experts explained.
Emergency opening of the toilet. Flight attendants in case of emergency can access the occupied toilet from the outside using a special additional latch. It will only be used in an emergency.
Handcuffs and pistols. Flight attendants are trained and prepared for several contingencies, including when passengers start acting a little out of control. Therefore, for the brawlers on board, there may well be handcuffs, plastic ties, and other means to immobilize the attacker.
In addition, most aircraft also carry a defibrillator that can be used if any passenger goes into cardiac arrest.
The small hole inside the glass of the porthole is a drain hole, a kind of safety valve to reduce the load on the portholes. By the way, it does not go outside, being in the inner layer of triple glazing.
Every tourist knows about “oxygen masks in the panel above your seat”. However, almost no one knows where the oxygen comes from. The fact is that there is a mixture of barium peroxide, sodium chlorate, and potassium chlorate – powders and liquids that react violently with each other, quickly releasing oxygen.
Coupe for the crew. This area is hidden from passengers. All long-haul liners have a special “compartment” where crew members can go to take a nap and rest.
Ashtrays in case someone still smokes on board, it’s easier to put out a “flammable” object in a technically adapted “device” than to eliminate the consequences of its falling into, say, a bucket of garbage.
There is a drain hole, gas masks, handcuffs, a horn, pedals, and much more on the plane. At first glance, these are unnecessary functions for the passenger and there is no need to know about them. But some of them may well come in handy in flight.
It turns out that airplanes, like cars, have sound signals. True, they only work on the ground. The horn is a means of communication, but it can also be used to alert ground engineers to a system failure or fire.
According to a British Airways pilot, the plane, like the car, has two pedals used to control it. When the plane is on the ground and taking off, the pilots control their feet – two pedals on the left and right.
The pedals even have brakes.
