8 Airplane Safety Features You Didn’t Know Existed

December 21, 2019 posted by

This is the bathroom door on an airplane and it can save your life. Not because it’s the only thing standing between you and the guy that ate an airport burrito
before he got on board. It actually has a hidden safety feature. Can you figure it out? In case of an emergency
that requires the pilot to land on the water, you’ll be grateful for
these little yellow hooks. The number and placement of hooks on each wing vary from plane to plane, but they all do the same thing:
help passengers to safety. They’re an anchor for ropes, which passengers use to steady and pull themselves across the wing especially during a water landing. The ropes and hooks can also be used to tether rafts to the plane so they don’t float away
as passengers board. Let’s say your plane does depressurize. You know the drill – pull down on the mask to extend the tube,
cover your nose and mouth with the yellow cup, and always put your own mask on first. But wait, why do you have
to pull down on the mask? It’s not to reach your face. It’s actually to start
a chemical reaction. There are no oxygen tanks on airplanes. They’re just too heavy
and bulky to be practical. Instead, the panel above your head contains a chemical oxygen generator. It’s a small canister that
holds sodium chlorate, barium peroxide, and a pinch of potassium perchlorate. And when all three mix together, the extremely hot chemical
reaction lets off oxygen. Your seat cushion functions
as a flotation device, but did you know it’s also fireproof? Let’s take this back a few decades. During a 1967 test for the
first Apollo moon mission, three astronauts were killed when the interior of the
capsule caught on fire. An investigation showed that the craft was filled with highly flammable materials including the foam in the seat cushions. This led NASA to conduct
a whole slew of research for a way to cover flammable things with a fire-resistant material. So in 1984, the Federal
Aviation Administration issued new regulations regarding the flammability
of airplane seats. And in fact, it’s estimated that 20 to 25 lives are saved each year because their seats don’t catch on fire. Above some of those flame-resistant seats, you might see a little
black or red triangle. Those triangles actually signify what’s nicknamed “William Shatner’s seat.” It’s a reference to a 1963
episode of “The Twilight Zone,” in which Shatner’s character sees a gremlin on the wing of the plane. The triangles signal to
the crew which windows have the best view of the wings in case a flap malfunctions or to check to see if they’ve been deiced. While you’re staring at
the gremlin on the wing, you might notice a small
hole in the window. Usually not a good feature for a window, but necessary in this case. It’s called a bleed hole. And it prevents your airplane
window from blowing out. That’s because the air
pressure inside the plane is so much greater than outside, which would cause any
normal window to explode. But the windows on an airplane are made up of three panes:
inner, middle, and outer. The outer pane takes the pressure, the middle acts as a fail-safe, and the inner is just there so passengers don’t
mess with the other two. The hole also lets moisture escape from the gaps so the windows
don’t fog up or freeze. If the idea of your window
popping out mid-flight causes you stress, just try
to keep the shade up anyways. That simple action could
give you peace of mind and potentially save your life. Before taking off and landing at night, crews will often dim the cabin lights and ask passengers to open their shades. This is to give their eyes
time to adjust to the darkness. In case of evacuation, passengers’ eyes will already be acclimated
to the blackness outside. If the lights stayed on, their eyes would need time to adjust and they’d end up wasting precious seconds stumbling blindly instead
of quickly evacuating. While joining the mile-high
club might seem like a fun idea, you won’t get the kind of
privacy you might expect. In fact, a crew member
could open the bathroom door at any moment no matter
if you locked it or not. On the outside of most
airplane bathroom doors is a little plate that says “LAVATORY.” And under that little plate is a latch that unlocks the door from the outside. This allows the crew
to access the bathroom in case of an emergency. While you’re in the bathroom,
you might notice an ashtray. “But wait,” you think to yourself, “I thought it was illegal
to smoke on planes!” You’re right! Smoking on an airplane has been banned on US airlines since the late 1980s and could saddle you with
a fine of up to $25,000. Even with the threat of a fine, the Federal Aviation Administration
isn’t taking chances. It lists ashtrays in
bathrooms as legally required to meet the minimum
equipment needed for a plane. Trash cans on a plane are mostly filled with flammable materials,
like cocktail napkins. So tossing a cigarette butt into one of those would not be good. After all, there are still
plenty of things in a plane that aren’t covered in
flame-resistant material.

    delta airlines would dump 60% of the passengers mid air starting from the fat ones,to save the cost…😋

  13. Master Pasha says:

    Thanks for the red arrow,I didn't see it

  14. RickaurisN says:

    Last time I checked the black triangle in the plane is the balancing point of the plane (center or gravity)

  15. Farhan Qureshi says:

    Thanks alot! I had really been seeking the answer of point no.6 of your video, for long. Thanks again.👍💕

    All bathroom trashcans have built in automatic fire extinguishers if fire is detected.

    I enjoyed this

    Actually, there are real oxygen tanks with pure oxyeng for the pilots in the emergency air supply

    Why does airlines don't have parachute under chair as safety feature

    Not an Secret anymore 🤣🤣🤣

  24. #TheCarEnthusiast says:

    I disliked this video because of Michelle Yan

  25. Richard Armstrong says:

    This is the best airline safety video I've ever seen, they should play this before every commercial flight

  26. Evan Fisher says:

    Ash trays exist on some aircraft because it was manufactured prior to the federal law

  27. L L says:

    What’s the point then

  28. Napoleon I Bonaparte says:

    I have devilish plans for that hidden latch on the lavatory door…

  29. Mike‘s World says:

    It is not true that airplanes have no oxygen tanks.
    The cockpit has oxygen tanks and all business jets have oxygen tanks. Passenger planes that fly over terrain, where the plane can’t descend to 10.000 feet for an extended time-period, for example over the Himalayas, you either need oxygen tanks or larger oxygen generators, because normal oxygen generators only provide oxygen for 15 minutes if I am not mistaking.

    Thanks for choosin the Arline of my home city, Hong Kong (SAR), China – Cathay Pacific for filming the demos
