  • There's almost no design for beauty in aviation.

  • The wing location, round windows, waist seat belts.

  • Why are all these things exactly that way?

  • Fasten your seat belts.

  • Youll get answers to a lot of questions about planes.

  • 1) How to go faster in line at the airport?

  • It’s better to stand in the leftmost line during registration.

  • Youre likely to go faster because most people are right-handed and intuitively turn

  • right.

  • 2) Why can’t you carry liquids on board?

  • Hazardous substances can be easily dissolved in liquids.

  • So, for safety reasons, only a very small volume of liquid can be carried on board a

  • plane.

  • 3) Why are the wings of most passenger aircraft located at the bottom of the plane?

  • It's called a low wing.

  • Firstly, if you install the engine under low wings, it will be closer to the ground and

  • easier to repair.

  • Secondly, the wings will take on part of the shock in case of a hard landing.

  • And if the plane falls into the water, then the wings become a life-saving pillow.

  • By the way, a plane can stay afloat from 10 minutes to 60 hours.

  • It all depends on the model of the plane, weather conditions, and pilot’s skills.

  • 4) Why are the wings of cargo planes located at the top?

  • Now this is called a high wing.

  • It's easy to load cargo onto these planes since the hull is very close to the ground.

  • Also, it's convenient to land on airfields with a not-so-well-prepared runway.

  • Debris won't get into the engine.

  • And last but not least, such a wing position has less aerodynamic drag during the flight.

  • And finally

  • 5) Why do many military planes have wings located in the middle?

  • Air flows better around the plane because of this arrangement of wings.

  • Thus, the aircraft develops greater speed.

  • 6) Why are most planes white?

  • Well, this color best reflects the sun's rays and the aircraft body doesn't heat up.

  • Also, the damage is best seen on white.

  • And finally, and perhaps most importantly, white paint is simply cheaper.

  • 7) Why are the turbines under the wings?

  • Maintenance of engines located under the wings is cheaper and takes less time.

  • Previously, airlines installed engines in the tail.

  • Expensive equipment and much more time was required to service these engines.

  • The cost of air tickets immediately decreased when they started to install engines under

  • the wings.

  • 8) Can a plane fly with only one engine?

  • Yeah, pilots easily control and land a plane if one of the engines stops working.

  • The plane will just lean slightly to the side during the flight.

  • But the coolest thing is that passengers will probably not even notice it.

  • 9) What does a small triangle on the aircraft walls mean?

  • These triangles are special labels for flight attendants.

  • They mark certain windows through which flashing indicators can be seen.

  • They signal retraction of the landing gear and closing of flaps.

  • If the pilot receives a signal about some problem, the flight attendants quickly find

  • the necessary windows and figure out the problem.

  • And for passengers, this is the place with the best view of the wings.

  • You can get the best photos here.

  • 10) Why are seat belts stretched across your stomach?

  • When the plane gets into turbulence, it's tossed a bit in the air.

  • The waist belt will simply hold you in place in case of a more severe shake.

  • Shoulder straps would require more space between the seats, and this is not justified on a

  • plane.

  • In a car, the impact is usually much stronger, so you need that shoulder strap not to woosh

  • through the windshield.

  • 11) Why do flight attendants also have a shoulder strap then?

  • Flight attendantsseats are much less comfortable than passengersones.

  • Theyre narrower and positioned facing the passengers.

  • Flight attendants need extra protection simply not to fall off their seats if the plane shakes

  • hard enough.

  • Also, they have to help and direct people during potential evacuation, and for that

  • they need to be in top shape.

  • 12) What exactly is turbulence?

  • Alright.

  • Imagine a big hot-air balloon.

  • See that flamethrower?

  • It heats the air, which makes the balloon go up.

  • Turbulence is the same: hot air.

  • Kinda like what I generate.

  • But it's created by nature, not by a flamethrower.

  • And there is a plane instead of a balloon.

  • That’s why you can feel like youre on a very bad roller coaster in turbulence.

  • Also, turbulence can occur if your plane gets into the wake (or exhaust stream) left by

  • another plane.

  • 13) Why does one of the flight attendants hold their hand behind their back when you

  • enter the cabin?

  • They count the number of incoming passengers on a special device and check that all passengers

  • are on board.

  • 14) How are airplanes protected from lightning?

  • Even if lightning strikes, the passengers won't feel it.

  • The entire aircraft is covered with an aluminum coating that conducts electric current but

  • doesn't allow it inside the plane.

  • All electronics and fuel tanks are equipped with additional protection too.

  • And of course, all this protection is tested by simulating lightning strikes.

  • 15) Why couldn't you use your phone on an airplane in the past?

  • Mobile phones were really dangerous for flights, but only when they had just appeared.

  • Their radio signal could disrupt the work of the electronics of the aircraft.

  • Fortunately, modern phones can no longer do this because their communication functions

  • have changed, and airplane mode has appeared.

  • 16) Why do some airlines recommend not using phones even now?

  • They impose phone restrictions because people should remain vigilant in case of unforeseen

  • situations on board.

  • It's quite difficult to get the passenger's attention when theyre watching a movie

  • or playing a game on their smartphone.

  • 17) In what cases do oxygen masks fall out of the ceiling?

  • Masks don't only fall out when the plane is falling, but when the air pressure changes

  • too.

  • Like if the plane decompresses for some reason.

  • Air is getting thinner in the cabin at a certain altitude.

  • So that passengers don't feel this, they put on oxygen masks.

  • Pilots quickly drop to a safe altitude, and you can breathe further without a mask on.

  • 18) Why are airplane windows round?

  • This is also a safety feature.

  • If the aircraft windows were square, pressure would accumulate in the corners, possibly

  • leading to damage.

  • With round windows, the load is distributed evenly and doesn't collect anywhere in particular.

  • 19) Why do landing gear tires not burst when landing?

  • The tires are designed for a load of 4-5 times more than they experience during landing.

  • The wheel will break sooner than its tire bursts.

  • 20) Why do they dim the lights in the cabin?

  • Passengers should get used to the darkness in case of an emergency landing at night.

  • The lights are turned off so that they can easily navigate when leaving.

  • For a similar reason, you are always asked to open the window shadesso that the

  • flight attendants can see what's happening outside and choose the best side for the evacuation.

  • 21) Why do airplane pilots always eat different foods before a flight?

  • This is necessary so that if one of them gets a food poisoning, the other could continue

  • the flight safely.

  • 22) What is the dirtiest place in the cabin?

  • Nope, it’s not the bathroom.

  • It’s the tray table from which you eat.

  • It has several times more bacteria than the toilet seat.

  • Also, some passengers use this table to change diapers for their babies.

  • 23) Why is food not very tasty on the plane?

  • This is not because the cook is lazy.

  • The fact is that your taste buds change a little at high altitude.

  • They become less sensitive to flavors.

  • 24) Is it true that hair and stubble grow faster on an airplane?

  • No, this is not proven by scientists.

  • The myth originated in the first half of the twentieth century.

  • Soldiers noticed that their stubble had grown after the flight, hence the legend appeared.

  • As for the airplanes themselves, the hair on the aircraft will grow at the normal rate,

  • and the planes are normally shaved 3 times a week.

  • Actually I made that up.

  • Hey, if you learned something new today, then give the video a like and share it with a

  • friend!

  • And here are some other cool videos I think you'll enjoy.
