1. Airplanes are lighting-proof
Most aircraft skins consist primarily of aluminum, which conducts electricity very well. By making sure that no gaps exist in this conductive path, the engineer can assure that most of the lightning current will remain on the exterior of the aircraft. Some modern aircraft are made of advanced composite materials, which by themselves are significantly less conductive than aluminum. In this case, the composites contain an embedded layer of conductive fibers or screens designed to carry lightning currents.
2. An airplane pilot and copilot are required to eat different meals.
Quite a few airlines require that the pilot and co-pilot eat different meals. This is to minimise the possibility of food poisoning impacting on the ability of both to fly the aircraft The pilot and the copilot eat different meals. Usually the pilot gets the first class meal and the copilot the business class meal.
3. The bathroom door isn’t really locked when you’re inside.
Lavatory doors can be locked and unlocked from the outside for a multitude of reason. It allows flight attendants quick access to locked lavatories in case of emergencies. In other instances, it allows the cabin crew to restrict access to bathrooms during takeoff and landing.
4. Passengers usually have no appetite for airplane food.
It turns out it’s not actually the airline’s fault. The reason why the airplane food tastes really bad is because the environment on an airplane changes the way a food or drink tastes. The inside of a commercial aircraft is insanely dry compared to on earth – even drier than a desert in terms of humidity. On top of that, the cabin is highly pressurized, which also messes with our perception of taste. What this means is that our ability to taste sweet and salty foods drops by about 30%. This means that if you thought that airline food was bland, it was probably because you were unable fully perceive all the saltiness of the dish.
5. You shouldn’t air travel if you have severe cold.
If you have allergies or a viral infection such as the common cold, your mucus membranes are inflamed and swollen. That swelling clogs the Eustachian tube, which connects your inner ear with the back of your throat. In a normal situation, this tube helps equalize pressure between your inner ear and the outside world. When it’s clogged on a plane? As you take off (and the air pressure in the cabin drops), higher pressure within your inner ear pushes out, but can’t equalize with the lower pressure in the cabin. The results: blocked ears, hearing loss for a few days, pain; and in more extreme cases, bleeding or even a ruptured ear drum.
6. About 1 in 5 people have some of fear flying, or “aviophobia”.
Fear of flying is a fear of being on an airplane (aeroplane), or other flying vehicle, such as a helicopter, while in flight. It is also referred to as flying phobia, flight phobia, aviophobia or aerophobia (although the last also means a fear of drafts or of fresh air).
7. You should never flush the toilet while sitting on it.
No big explanation! Simply, the pressure is so high it may cause harm to you!
8. Oxygen masks on planes last between 10 and 20 minutes only.
Hopefully enough time for the plane to descend to 10,000 feet, where oxygen isn’t needed. Up front, the pilots will don their own masks and commence a rapid descent to an altitude no higher than 10,000 feet. If the emergency descent feels perilously fast, this isn’t because the plane is crashing: it’s because the crew is doing what’s it’s supposed to do.
9. Mercury Is Not Allowed On Airplanes!
Mercury is already a poisonous substance – neurotoxic to humans and most life, despite looking like the cool liquid metal that the bad guy from Terminator 2 is made from. However, it is also used in things like thermometers and has a lot of valid applications, so some may be surprised that it is banned from existing anywhere near an aircraft. The reason is that planes are made almost entirely of aluminum, and when recently scratched aluminum comes into contact with mercury, the resulting chemical reaction can tear through the aluminum like a hot knife through butter.
10. Cabin crew have sleeping quarters onboard larger international flights.
They are located above first class, just under the ceiling of an aircraft. These windowless rooms contain 8 bedrolls, some of them even have entertainment systems.
and we have one more crazy fact which most of passengers don’t know!
11. Lights are dimmed in the cabin on landing not to save money.
But so that if the landing goes badly and the lights fail, passengers’ eyes will already be adjusted to the darkness.
Pilot Chris Cooke, who flies with a major domestic airline, has told Travel + Leisure magazine that the procedure is a precautionary measure that allows passengers’ eyes to adjust more quickly to darkness. This is in case something goes wrong on descent and an emergency evacuation is suddenly required.
He explains, “Imagine being in an unfamiliar bright room filled with obstacles when someone turns off the lights and asks you to exit quickly.” He added that passengers are also asked to leave blinds up upon descent for similar reasons. Unobstructed windows can bring in natural light in case lights are suddenly cut out and help guide passengers to safety.
