Why Airplanes Don’t Have Shoulder Seat Belts But Cars Do


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. You’ll 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. You’re 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 attendants’ seats are much less comfortable
than passengers’ ones. They’re 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 you’re 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 they’re 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 shades — so 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

  1. The triangle on the wall indicates the centre of gravity for crying out loud and not for the lights. The strobe lights on the plane's wings are always on during flight and does not indicate anything related to flaps or landing gear!!

  2. 4:47 i don't mean to criticize anybody but actually the the turbulence caused by the wing vortices of another plane is much harder than the exhaust stream

  3. The thing about the lights is wrong , the red and green lights on the wing tips are for other pilots and people of the direction of the plane , there is also the light for inspecting the wings and engines , it is not for showing if the landing gear is extended

  4. Airlines don't allow phone use because many passengers are jerks and they don't want to play referee with pax getting upset with others being loud and rude.

  5. One time there was a lot of turbulence on the plane I went on (I went on Jetstar it’s A Australian airline I was going from Mackey to brisbane)

  6. i saw this exact channel but in italian.. is that you or someone who s stealing your vids? btw the italian channel is called IL LATO POSITIVO

  7. As a long time pilot, 40+ years as a private, military and commercial pilot, I found this video painful to watch. It seems almost as if they just made up answers rather than bothering to do some research. There was usually some bit of truth to the answers but the answers were extremely simplistic, incomplete and often contradictory.

    Just some examples: 1.why are wings on commercial aircraft on the bottom? Well some passenger airliners have the engines on the bottom, some have them on top. Some cargo aircraft have the wings on top, some have them on the bottom. Some fighters have the wings in the middle, some have the wings on the top, some have the wi gs on the bottom, for a variety of reasons.
    2. Why do the pilots and flight attendants and most private planes have lap and shoulder harnesses but passengers on commercial flight usually do not (except often in first and business class) because the airlines want to spend the least amount possible and want the least weight possible on safety gear. So it's clearly better to have a 4 way harness, as the pilots of most airliners and military aircraft wear, but most of the passengers just get the bare minimum lap belt.
    3. Engines on the wing has been a thing since the first 707 airliners in the late 50s, not a new development that followed tail mounted engines. And there was no sudden drop in air fares when the the 727s, with their rear mounted engines, went out of service. Most business jets still use tail mounted engines, because they are quieter, but so do many smaller airliners.

    I could go on and on but the bottom line, simplistic, untrue, incomplete, and just plain made up answers posing as the real deal.

  8. Wait what? Planes do have shoulder belts! It’s only economy that has the non-shoulder belt! Please research a bit more deeper next time 😉

  9. Ehmm… No, the most left line is NOT faster, but there could be less people in it. The trick is to go to the line… that is shortest (with fewest people in it) – wow what a trick…

  10. Some planes actually have seats with shoulder belts. Those are usually business and first class seats since they often are placed diagonally from the direction of travel.

  11. most of the stuff said is not true here is just one of them why can't bring big bottles is because what happened in 2006 attempted terrorist attack. The terrorist intended to mix two chemicals to cause an explosion.

  12. Wing position doesn't really have too much of an affect on speed. High mounted wings are more stable which is why they are used on many lighter aircraft. Low mounted wings while less stable are better structurally for large wings. Many fighter aircraft have high or mid mounted wings to make up for the extremely unstable anhedral wings. It is not faster to have the wings in any specific position.

  13. Planes do have shoulder seatbelts, just not in the economy cabin. On some airlines ex: Asiana, Qatar (in forward facing Qsuite only) you will find shoulder seat belts in their premium cabins.

  14. #15 ignores that modern phones don't disturb the plane controls even without airplane mode and that the instruments are now less sensitive to interference too.

  15. #16 contradicts the fact that there had already been movies playing in planes for a long time, and that we've been able to get TV on individual seats in some planes for years too (with the only key difference being that they can interrupt their signal in an emergency).

  16. 18: Why are airplane windows round?
    They're NOT!
    "If the aircraft windows were square…."
    That example you gave is not one.

  17. Many business and first class seats have a shoulder strap.
    Many of your videos are absolute rubbish that’s made up with no fact checking.
