an airplane is a complex machine
ingeniously designed to the very last
detail yet some things about them still
make no sense
why do boarding and D boarding takes so
long
why does a plane need multiple engines
if it can fly with just one and is the
black box really black it's time for
some answers oxygen masks don't last
long the safety instructions always tell
you how to use them in case of a sudden
loss in cabin pressure but they don't
tell you the oxygen in that mask will
only last 15 minutes no need to panic
this amount is enough to provide
passengers with oxygen until the plane
reaches a safe altitude when it descends
below 10,000 feet everyone on board will
be able to breathe normally again planes
can handle extreme temperatures but it
depends when the pilot is sharing flight
info with you they nonchalantly mention
extreme outside temperatures of minus 70
degrees yet similar figures can keep a
plane from taking off in the first place
the temperatures at cruising altitude
and on the ground are entirely different
things on the ground
bitter cold in the minus 60 degree range
makes starting the engine much harder
add to that de-icing the plane and
runway as well as keeping maintenance
crews safe out there in sub-zero
temperatures and you can see the problem
planes don't need two engines to fly if
one engine fails the aircraft can
continue flying safely for over five
hours granted it'll be less
fuel-efficient and gradually drift down
from normal cruising altitude but all
modern planes on long-distance routes
are tested to cope with that situation
and pilots are trained for it in fact
planes can even glide for a while with
no functioning engines at all
okay they might not drop from the sky
immediately but I still like having all
those backups just in case
pilots fall asleep and it's okay thanks
to the wonder that is autopilot a plane
can perfectly fly itself across the
globe meanwhile the human pilots can
doze off but there are regulations on
that only one pilot at a time can take a
snooze and there are still things an
auto pilot isn't capable of taxiing
landing setting the start and end
locations and making witty jokes while
briefing passengers about the flight the
way D boarding is organized makes no
sense
d boarding usually adds up to an extra
half an hour to flight time but computer
simulations show that it can be done
35% faster all you have to do is D board
by aisle not by row let's imagine a
cabin layout with one aisle in the
middle and rows of three on each side
first left aisle passengers leave the
plane then the right aisle next our
middle seat passengers on the left side
followed by those on the right
finally the left window seats and then
the right it might be a problem for
passengers traveling together but it's a
great way to avoid aisle blocking when
recent airlines aren't using this method
just yet they're more interested in
making some extra money selling
first-class and priority seats so
they're chaotic boarding would work
better than groups the way it is now by
group the plane gets loaded from the
back to the front
after first business and priority
classes of course well la-dee-da the
whole process would be much faster if
people were allowed to choose their own
seats on the plane they feel the rush to
grab a spot instead of standing around
putting their carry-on in the bin an
even better way to cut down boarding
time would be to let passengers board by
aisle first all window seats then middle
then aisle again it would cut down the
time we have to wait for others to get
their stuff put away but for some reason
airlines aren't doing it
you can open the plain bathroom from the
outside all you have to do is flip the
switch underneath the laboratory sign no
worries though it's not widely used by
curious passengers but by the crew when
they think the person inside might need
help
airplanes can trigger lightning they try
to avoid flying in lightning storms but
they are designed to withstand it just
in case
plenty of aircraft gets struck more than
once a year
and are perfectly fine afterwards more
than that
planes can cause lightning themselves
when they fly through a cloud that's
heavily charged the bolt starts from the
fuselage and travels out black boxes
aren't even black the flight data
recorder more commonly known as the
black box is actually bright orange it's
covered in eye catching heat-resistant
paint to make it easier to find if
necessary they're still called black in
honor of the first boxes whose color
matched they're nicknamed the dirtiest
place on the plane isn't the bathroom
that my friend would be the tray table
you eat off of in fact there were about
10 times as many bacteria on it as there
are on the toilet the seat belt buckle
and overhead air vent have roughly the
same amount of germs as that toilet
flush button this is disturbing the
blankets and pillows aren't always
cleaned after each passenger either and
one more thing to keep you from ever
wanting to fly yet the provided
earphones have most likely been in
someone else's ears before you clean air
is as dry as the Sahara Desert to keep
the air clean planes had the same air
filtering technology as hospitals the
price you pay for that cleanliness
pressurized onboard air is super dry
only about 20 percent humidity the same
as in the Sahara your hands get dry your
throat and nose feel like sandpaper and
your whole body loses a lot of water
especially on long-haul flights they
could add an air humidifier to help the
situation but they
also need to load the water tank for it
and that equals extra weight and more
money spent so for now drink lots of
water to stay hydrated plain food isn't
that bad but flight conditions make it
tasteless airlines don't hire bad cooks
to make your meals taste like cardboard
the difference in air pressure and that
same super low humidity numb about one
third of your taste buds just like when
you catch a cold
so it's not the food it's you pilots and
co-pilots don't usually eat the same
food not because they have completely
different diets but for your safety yeah
if something is wrong with one of the
meals at least one of the pilots won't
get food poisoning and will be able to
take care of the flight if they must eat
the same meal for some reason they'll at
least do it at different times so they
don't feel sick together that's
comforting
global warming makes turbulence worse
the more carbon dioxide gets in the air
the more likely turbulence is to occur
during the fly that's because
temperatures rise in the lower
atmosphere and drop in the stratosphere
causing the tug-of-war effect in the air
researchers believe things will only get
worse with time
it could also accelerate the jet stream
and make westbound flights longer than
eastbound ones dimming the cabin lights
isn't done to help you fall asleep sure
it helps but safety comes before comfort
on the airlines priority list in case
you'll have to leave the plane in an
emergency the dim cabin lights will make
it easier for your eyes to adjust to the
darkness when it's nighttime and flight
attendants don't ask you to raise the
window shade to enjoy the views they
just need to see which side of the plane
is better fit for an emergency
evacuation
the plane environment makes you more
emotional yes it does a survey by
Gatwick Airport found that altitudes
make passengers more emotional even if
you aren't afraid of flying getting to
the airport and through all the security
and long lines can be physically tiring
then comes changes in air pressure dry
air and often turbulence there's also
the emotional component of saying
goodbye to your loved ones and the plane
environment with unknown sounds all that
put together exaggerate your emotions
the same survey mentioned that people
are more likely to cry at movies in the
air even if they never do it on the
ground so if you see me crying as I'm
watching Shrek
it's the cabin pressure okay oh hey if
you learn something new today then give
the video a like and share with a friend
and here are some other videos I think
you'll enjoy just click to the left or
right and remember stay on the bright
side of life
