程度の副詞

an airplane is a complex machine ingeniously designed to the very last detail.

Yet something's about them still make no sense.

Why do boarding and de boarding takes so long?

Why does a plane need multiple engines if it can fly with just one?

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.

This amount is enough to provide passengers with oxygen until the plane reaches a safe altitude.

When it descend 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 mentioned extreme outside temperatures of minus 70 degrees.

Yet similar figures can keep a plane from taking off in the first place.

The temperature's 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.

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 auto pilot.

A plane can perfectly fly itself across the globe.

Meanwhile, the human pilots can doze off.

Only one pilot at a time can take us news.

And there are still things an autopilot isn't capable of.

Taxiing landing, setting the start and end locations and making witty jokes while briefing passengers about the fly the way de boarding is organized makes no sense.

De 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 de board by I'll not by row.

Let's imagine a cabin layout with one isle in the middle and rows of three on each side.

First left, I'll passengers leave the plane, then the right eye on 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 travelling together, but it's a great way to avoid I'll blocking one reason airlines aren't using this method just yet.

They're more interested in making some extra money, selling first class and priority seats.

So there 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 dah.

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 Ben.

An even better way to cut down boarding time would be to let passengers board by.

I'll first all window seats, then middle.

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 plane bathroom from the outside.

All you have to do is flip the switch underneath the laboratory sign.

It's not widely you bi curious passengers, but by the crew when they think the person inside might need help.

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 usual AJ and travels out.

The flight data recorder, more commonly known as the black box, is actually bright.

Orange is 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 their nickname, Dirtiest Place on the plane isn't the bathroom that my friend would be?

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.

The blankets and pillows aren't always cleaned after each passenger, either.

And one more thing to keep you from ever wanting to fly again.

The provided earphones have most likely been in someone else's ears before you.

Plane here is as dry as the Sahara Desert.

Planes had the same air filtering technology as hospitals.

Only about 20% 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'd 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 and make her meals taste like cardboard, the difference in air pressure and that same super low humidity numb about 1/3 of your taste buds, just like when you can't you call.

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 we'll be able to take care of the flight if they must eat the same meal.

For some reason, though, at least do it at different times so they don't feel sick together.

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 airline's 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 yume or emotional yes, it does.

A survey by Gatwick Airport found that altitudes make passengers Maur 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.

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.

Oh, hey, If you learn something new today, then give the video alike and share with a friend and hear some other videos I think you'll enjoy.
