Find out all the secrets of a commercial flight so your mind will not invent possible uses and failures of all that you see around you.
Do you know all the secrets of the planes?
1 – The cooper vane
After the hijacking of an aircraft and the subsequent escape of the hijacker jumping in a parachute of the same was installed in all commercial aircraft a small palette on the outside which prevents the opening of doors in flight.
2 – Grab bars in the hallways
These handles are only for use by flight attendants in case of turbulence, and they have to stand.
3 – Hooks in the wing
These hooks are to hold the slides of exit in case of emergency.
4 – The black triangles
You’ve probably noticed that there are a few small black triangles divided by the plane and that probably made you wonder during a flight. What seats more dangerous? Which are the least? Do they tell the weak point of the plane? None of that…
The black triangles mark the place from where you can have a better view of the wing of the plane. On occasions, the captain may need to be able to see the wing to verify that everything works correctly and it is at this point that you must look at.
5 – Auxiliary Power Unit
The noise you hear while you embark the plane is that of the auxiliary power unit that gives power to the aircraft while this is still off. It is what keeps the lights and services of the interior operate despite the plane being without “boot”.
6 – An axe in the cockpit
The axe is an element of necessary emergency in a plane to open a stuck door, help control a fire or even open an exit to the outside. The axe should be stored in the cabin of the pilot, so there is no risk that a passenger is accessing it.
7 – Air Service
There is an air secret service that travels on commercial flights where it is suspected that there may be an attack. There is even a movie about it.
8 – Air conditioning
If you’ve ever wondered where the air conditioning of the plane comes from, you would probably prefer not to know. The air enters the aircraft through the turbines, but don’t worry, how it happens is that a few filters retain up to 95% of the bacteria.
9 – The hole in the window
Sure you already know this. The hole is to maintain a stable transition between the pressure of the exterior and interior and the 3 crystals that make up the window.
10 – The crew room
The myth about the bedrooms of the hostesses in the flights is real. On those long flights, they have rooms where they rest.
11 – Unlock the door to the lavatory
If your child has been locked up “accidentally” in the bathroom, you do not need to call the flight attendants to get them out. You only have to lift the sign lavatory and unlock the door with the lever that is under it.
