I wholeheartedly thank you for this beautiful video. After watching this, I can finally and confidently say I still don’t understand how something so heavy can fly.
🤣🤣😭 same 😩
Speed and air takes those weight factors away. Making planes able to lift off and glide through air. Common sense
you made my day
I used to wonder how Airplane take off too being that it's so heavy. But we also have to remember the first Airplane came out in 1903, Making Airplne a 109 years of mankind enginuity. I wouldnt be surprise if come with an airplane that is able to take off and land like a helicopter. Hope I'm still here to see one and fly in one.
Right 😂
Please dont use mph, use nanometers per week
+Flashbang237,
Furlongs per fortnight...
nah use yoctometers per 1000 years
Use mileage per horse
😂😂😂😂
Nah.... planes use knots
While watching this video, I really liked that the video added a lot of visual aid to try to explain the reason for lift and how an airplane can stay in the sky. This video included a lot of other topics such as speed and air density which are things to look at when determining how lift works. This was a nice addition.

No, I didn’t notice that planes tilt up. I always thought that they tilt towards the ground.
Aeroplane is a perfect example of engineering
you didn even talk about the shape of the wings like WTF?
Rangkara Without the shape, there's no point in even having the wings.
The Bernoulli Effect requires a wing with a flat bottom and curvy top, so that the air on the top moves faster, and reduces pressure fro the top while maintaining pressure from the bottom. This creates net lift force. This is the single most important aspect of plane flight.
vandertuber yes, but there are some airfoils that aren't curved on top, but they still use the same principle 😄
The bottom of any commercial airliners is literally anything but flat.
+vandertuber and others,

It is actually the most common misconception held by amateurs and has been around for so long and repeated by so many people that it is all you can find...bad science.
... Flat and symmetrical wings fly just fine. Here's some authoritative sources:
First, Bernoulli explained CORRECTLY

Video lecture explaining Bernoulli. (focused on a wing, but a good explanation of radial acceleration) If you understand Newton, you'll clearly understand Bernoulli and lift much better after this video The paper he mentions is linked after this.

PLEASE NOTE
1) When Prof Babinsky says "Coanda" he technically misspoke. The term "Coanda Effect" is defined for high speed jets or sheets of air FORCED over a curved, convex surface into an _otherwise still environment_, NOT for a wing moving through air. It simply states that a forced jet or sheet follows the surface. Coanda did note the pressure reduction. While the two may be due to similar physics a definition is a definition.
2) YES, he stops short of describing the downwash, but that is a result of the pressures, so it is not a contributor to lift as commonly described.

Once you really understand lift you will not be baffled by the fact that the fastest moving air around a wing is just UNDER it! No, I am not crazy. Put on your best scientific observation glasses and look at the following.

How Planes Fly. ruclips.net/video/aa2kBZAoXg0/видео.html
Pounds? Miles? What is this, the Middle Age?
It's Murica
Its englarica
lmfao
it's aviation
‘Murica you French hippie
I understood way more from this video than I ever did in my air cadet principles of flight lessons
RAF air cadets?
I've always wondered why planes flew so high until now
Correction --> How do airplanes fly
she is talking about airbuses. just airbuses. no other planes
There is nothing about my channel. So gtfo but all planes rely on the same principles to fly as what Is said in the videos
The Old Blender um... No she's not
i know how they fly but it still blows my mind 😂
Engines generate thrust which help propel an aircraft against more molecules of air which can they be used to form a pressure differential above and below the wing, - they don't generate lift themselves. The opposite of thrust is drag, and not gravity. The engines go through the 4 stages of combustion; Intake, compression, combustion and exhaust to generate thrust, the wheels are not motorised. Also, the aircraft tilts upwards during take off because the elevators which change motion along the y-axis utilise a pivot point much further back towards the tail. If I balance a pencil on my finger and press one side down, does it rise in parallel fashion? No, the point of furthest perpendicular distance from the pivot point does, the force is called a moment. The same thing applies with ailerons along the z-axis. Not to mention, even if the elevators were on the other side, its best to take off from the nose wheel first as it would collapse under the weight of the aircraft if left on the ground individually, the main landing gear is much stronger, and the essentially incompressible hydraulics are much more advanced. The wings themselves already induce and angle of attack as the trailing edge of the wing is not directly behind the leading edge, and this only applies to a certain extent. After that point, an increased angle of attack creates a suction type force similar to aerodynamics experienced in a wingtip vortex which incorporate even more drag, so more isn't always better.
habib syed This is a better explanation flight than the video.
Farmboy1544 thanks bro. They think we are 5 year olds.
basically my comment except way better. 10/10 would read again.
This is probably a very informational and intelligent comment but I’m dumb and don’t understand anything
This comment is so attractive even though I only understood around 60%.
I still can't really understand how plane can keep going in turbulance....how can it keep steady through a thick cloud. Incredible
At that speed, the air is dense like water. Consider turbulence like waves in the water, or bumps on the road.
Can you imagine the engines failing right after take off. Terrifying.
IKR.
They actually have several times throughout the years of flying. But miraculously a big jet can still land if close by a spot to land.
0:26 Newton was doing Yoga when the Apple fell in his hands 😂😂😂😂🤣🤣🤣
It's basically how every plane flys! 😂
Jupiter space it's*
Bic Boi indeed
I took a flight from NYC to Seoul on an Airbus A380, a massive 4 engine, double decker behemoth. I am amazed it managed to take off and land. I am amazed it does so regularly. It’s just so massive it’s hard to believe it can fly.
+ProtagonistNonTheist,
Yes, however it has really big wings. The pressure difference she mentions is only about ONE psi TOTAL, or about a change of 3.5 % on the top and bottom of the wing at takeoff. A small change on a large area.
...
Up at altitude, the changes would then be 10 times or a more impressive 35%...
thanks for this video
This was very informal and interesting!! Even tho I know how planes fly this taught me more! Thanks :)
who asked
When the angle of attack suddenly increases, flow on the lower wing apparently needs to double back round the trailing edge. Because our atmosphere is not a superfluid, what actually happens is that the flow separates at the trailing edge and a starting vortex is dumped on the runway. By the principle of conservation of vorticity, there must be vorticity of opposite sign associated with the wing, and this generates lift by the Magnus effect.
When the aeroplane lands and comes to rest, the vorticity associated with the wing is dumped as a stopping vortex. It is possible to visualise the starting and stopping vortices. If the aeroplane accelerates or decelerates, just enough starting or stopping vorticity is shed at the trailing edge to keep the flow speed the same above and below the wing. This is called the Kutta condition. Instead of the Magnus effect, I should perhaps have talked about the Kutta-Joukowski circulation theorem. The wing generates the same lift as a rotating cylinder with the same total vorticity.
I *LIVE* for these videos!! ❤
the thing keeping the plane in the air is the engines
*mind blown*
Aviation speed is usually measured in knots. When commercial aircraft are at cruising altitude, mach number is used.
pounds, miles, etc what the heck was that dawg?
Deri Jericho Units of FREEDOM.
Dennis Xu LMAO
ironically they're called "imperial" units
Deri Jericho some bullshit
Lol I’ve never been on an airplane in my life.
Upon take off, it actually not 180mph or more. It depends on the weight of the plane. An airbus A380 and Boeing 747 need more than 250 mph (sufficiently 180-200 knots) to rotate
Thank you Mike. Your exercise on peripheral neuropathy seem to be helping me. I have to be patient . Thank you. Mary
Because they have wings.
If they only have wings that makes the plane a huge glider
marsel egan exactly! The aircraft also needs thrust to make it more controllable.
I'm not a weeb dumbass
Awesome, but then also it seems to be a magic !!
This is the best description of flight I’m yet to see so far
Great video and presentation!
Theres no limit in size.
It depends the wing size more engines or large engines and strong materials.
Longer runway idk what you’ll add more.
Mph? Why don't you use knots?
Cuz American channel and we're American
Yeezy not everyone. Learn to measure in SI units and stop using dicks and hands.
Yeezy but knots arent metric or imperial. theyre pretty much only for aircraft
Easiest way to visualize the amount of speed we're talking for the general viewer is to mention something we are likely all familiar with, in this case, ground transportation. We all know and understand the speed of a car. Since this video caters to the American audience, they chose MPH as they figured converting to kmph or knots would be up to the minority viewer.
Because not everyone is a fucking pilot
Wings deflect an amount of air flowing over the top of the wing and then downward equal to the weight of the plane! That’s how wings work!
Thanks for the information Tech Insider!
Very informative, thank you
Very informative thx💯
Best explanation ever!!
Now i love the voice demonstration... Awsome work.. Love your videos..
THIS WAS ACTUALLY UNDERSTANDABLE :0 THANKS
Love the video
Thank you 🙏.
The great bastard
I love 2 door cinema club!
Thanks
How cute! The last part of the video were Jin Air flight attendants.
Very Interesting
THANK YOU! I have a question: how to create that angle of attack? Does the plane lifts the nose by pivoting at the tires? Pivoting, is that the right term? Sry im not a science person.
Super dope. Eye want 2 know more
0:57 miracle on the hudson river xD
I always wonder how 🤔tnx.
Finally a video that explains how airplane fly in the simplest way.
too bad it's wrong..
Hi! Can you start including metric measurements as well? It would be nice to at least have it in the subtitles
Answer: *_Thrust from the engines and lift from the wings_*
160 MPH or ~ 180 knots
The only passenger plane with a MTOW greater than 1,000,000 pounds is the A380, which is the biggest passenger plane in the world. The only bigger is the cargo An-225, the heaviest plane ever built.
Very informational
Good information
Use kilometres not miles
much bigger portion of the audience will understand it better
that would fit better than kmh as that is what planes actually use
Ludvig Juel Martens More people use metric....
Yeah but we americans need the most help. You can figure it out. We cant (1 mph = 1.706 kmph) 550 mph = 938.30 kmph...
Im american. I did that in my head. Im proud. Give me love
Achilles Marcus U metric guys are like children. just google the conversion
Very well made video, thought to myself "HOW DOES SOMETHING SO HEAVY FLY?!" so same principle applies, lets say i wanna be superhero, BIRDMAN! Lol if I had wings, ran REALLY fast, then once off had engines to keep air moving under wings fast, I'd fly too? Why hasn't this technology been made yet if it's possible for planes, something smaller like a single human seems easier?
Look up wing suits
Pray for those who are being effected by hurricanes!
*affected
But yes, I hope everyone will be safe down there.
xmr7 pt95 God exists and I Pray and good things happen
Davidtube HD you're subbed to Logan fucking Paul, no wonder why you haven't ripped off that God bandaid yet. You're literally 11 years old.
Benjamin Dover So what,is that going to stop me believing in God
Airplanes are incredible
Good teacher
Now you should do a video explaining how "Pop filters" work
You don't need to be born with wings to fly, just some human ingenuity and a dream.
How do they get it to do the tilt at lift off?
hope you make more videos about aeeoplanes
Nice video
In lamen terms. Thrust must exceed both the weight of the aircraft and gravitys pull to take off. And continue to rapidly accelerate to reach such heights. Thats why the engines are so critical. Further more. Supersonic flight invoices a whole new dimension of science and complex situations. Mainly heat tolerance. All that friction at hundreds of miles per hour creates a lot of thermal expansion
Wonder of wonders. What you have here is correct and you avoided all the common misconceptions. It is simplified to some extent, but not to the point of being incorrect, or false science. I don't know who you are, but Good job.
Please add metrical measurements.
1st, im pretty sure planes use knots
2nd, metric system pls?
Works for me!
Magic
Knots and metric system pls.
Because science!!!
I always thought elevators on the stabilizer gave the lift
They give the angle of attack
Yeah they tip the nose up
The elevators actually create a down force on the aircraft, not lift.
You for got to mention the Elevator's function in take off
They lift off with the hidrolics and use knots instead of mph
Thank you for telling this
My dream job is to become a International pilot and know i know how they do that
Tech Insider put also in Km/h please!
Can you make a video on plane crashes throughout the years
2:00 clocking over 8000ft/min Ascent hahahah
Title: How massive airplanes fly
Thumbnail: E175
Me:🤦🏾♂️
You forgot to talk about the flaps that gives more lift in the airplane when it’s taking off
“liftoff” lol
an eye opening video, should pay more attention when the stewardess show us how to buckle the safety belt
crazy how birds just figure it out after getting some feathers
The bigger the planes the bigger the engines or the bigger it is it gets more Engines like compare the A340 and the 777
I was startled for a second at the birds name, I thought i hear the great bastard lol. Almost stop my niece watching.
Wait what???? Well you learn something new everyday folks
1:15 wheelie
Just like many others, you missed to explain HOW is the nose lifted.
Which are the controls and components used.
Wow
Flaps? Elevators? There's still some stuff you can cover here
I lost it when they used imperial measurements
WOW
Mr.Weasley should watch this.
And 3)✨🌌 Magic 🌌✨
"Massive airplanes" huh? Too bad there isn't a word for that, it makes me want to "jet" right up out of my seat.
Michael B Massive is relative. Compare a Boeing 737 to an Airbus A380. THEN repeat your comment.
Wow you're brilliant. I'll rethink everything now. A jet is an airplane with more than one engine which would include everything considered massive.
Michael B ur mum is massive
So is your wit. Did you stay up all night writing that?
Michael B yes, im proud of it :D thanks for noticing!
Two things: metric units? At least in brackets? At least in subtitles? And you never mention an airfoil - which is what basically generates high/low speed of air and thus high/low pressure.
Actually, the angle of attack of the wings generates more lift than the airfoil principle (bernoulli)
