It's hard to surprise an experienced traveler, but there will be plenty of interesting things about the plane that you may not have thought of. On the Bright Side page, some secrets are known only to the airport staff and the most curious guests. Please join us to learn about top 10 extremely interesting things on the plane that you may not know in the article below!
Hook above the wing
Most aircraft use emergency exits but when passengers have to stand on the wing, its surface is very slippery. To move more easily and safely, a special hook was designed including: a seat belt that is threaded through it and attached to the other end at the exit door. When incidents occur, passengers will snatch the cord and evacuate it in time.
Ax in the cockpit
According to the aviation law of many countries around the world ( like the US ), the ax is an emergency device equipped on board and stored in the cockpit. The ax can be used to fire, open the door when stuck or even create an emergency exit right on the fuselage in an emergency.
Small hole in the window
There are 3 layers of glass on each of the aircraft's windows: the outer layer is tough, the inner layer protects against accidental damage in the aircraft and the middle layer - there is a hole created, to hold Pressure and pressure adjustment between inside and outside the aircraft. You will see a small hole in each window that adjusts the airflow inside the cabin . In addition, this small hole helps balance the pressure difference, avoiding dampening and reducing condensation on the glass panels.
Energy support unit (APU)
When we board the plane, we often hear noise even when the engine is still inactive. This is caused by an APU ( Accelerated Processing Unit ) that supplies power to the systems while the engine is being activated. It was also the sound of starting the engine. APU will power the aircraft when needed.
Air Marshal service
The Air Marshal Service is understood to be a sinking police on airplanes - these people operate secretly, tasked with resolving incidents on aircraft, controlling violence or even escorting terrorists. Countries like the United States, France, Canada and some other countries have national Air Force services and this is a topic that has been noticed by many filmmakers.
Crew rest area
Some aircraft have retrofitted some small hidden rooms for crew to relax in long flights. However, these chambers are often specially designed, not very comfortable: you can only crawl into it, lie down and rest for a while.
Emergency door handle
These handles are designed in front for flight attendants to keep balance in case of incidents, panic on the train and avoid falling over when passengers push, find the exit.
Air conditioning system
Have you ever wondered where the air we breathe on the plane comes from? It is transmitted into the aircraft bay through a compression phase of each engine turbine. This is probably the reason that people always think that the environment on the plane is dirty. However, you don't need to worry: The air entering the chamber has been filtered and cooled. After passing the filter, the air was removed over 95% of the bacteria.
Cooper propeller
This device appeared on the plane after an incident from the case caused by Dan Cooper. He stole a passenger plane, after receiving a ransom, he escaped by parachute. Since then, all Boeing and Airbus aircraft have been equipped with a " Cooper propeller " - a device that does not allow opening between flights.
Black triangle
You may notice small black triangles on some planes. The captain of Airbus A320 said that they marked the places where the wing could be best seen. They can check unexpectedly from this point if the pilot has doubts about the position of the flaps, or notices that the indicators are unsatisfactory. Fortunately, this is a rare case.
