The reason for the lift generation is not Bernoulli's principle, it's Newton's 3rd law. ruclips.net/video/w78JT6azrZU/видео.html . More specifically, apply Newton's 3rd law on down wash produced by the airfoil shape. Please watch the Airfoil video by Learn Engineering to understand this concept completely.
Downwash causes INDUCED DRAG by tilting the relative incoming velocity vector by an induced angle of attack and hence the lift also tilts backwards, creating a small yet measurable horizontal component. Lift is caused by the pressure difference between the top (suction side) and bottom (pressure side) of the airfoil, creating a net upwards force. Bernoulli's principle and it's equation is probably the most misused in all of engineering.
The animation used here is a good example of a 'lie-to-children,' where the explanation is so overly simplified as to be just plain wrong. The pressure differential between the bottom and top of the airfoil _does not_ create lift. Period.
Waseem Hashmi you misunderstand this. When a fluid flowing past the airfoil, it exerts a force and lift is a component of this force. The airfoil exerts a downward force on the air, according to Newton’s third law, an opposite force exerts upward which is the lift. And also how do you explain Newton’s law applies for helicopters but not airplanes? What’s the difference between the airplane’s wings and helicopters blades? The same law applies to both of them, the difference is the blades have to turn to go through the air. Give the blades an angle just like we give the wings of the airplane to create that lift.
Waseem Hashmi I would say Bernoulli’s principle applies also because it creates that pressure due to the speed of the air. Newton’s third law also applies because the lift is an opposite force of the downward force that the airfoil exerts. I’m in Electrical Engineering but I do understand physics, if you are in mechanical, please explain to me the difference between the blades and the wings. The speed of the air through the blades also creates pressure according to Bernoulli. Force(lift) is also an opposite force of the downward force. Please explain this to me.
I was feeling a bit down tonight. For some reason watching simple, informative videos like this is comforting and brings your spirits up especially watching it late at night :)
Flying in 2022 is so commonplace many don't awe in the beauty of how amazing flying is, the whole concept of a machine design basically as a bird to get you to places quicker. I will always be in awe of Flight...
I've flown more times than I can count, and yet, every time I get on a massive jet, a part of me isn't quite sure that those engines can get that monstrous metal tube off the ground. And yet... they never fail.
I’m 36 yrs old and for the first time in my life, last August I ride a plane at first I was worried and after that I just enjoyed the journey. I enjoyed being on the plane. 😊
Unfortunately it muddled some of the most important details, that I wish to share. If you don’t are that’s fine, but I love this subject! There is a fallacy contained within this video that I wish to correct, in that the downwash is not what causes lift. The simscale animation played just after this that was claimed to support this actually shows it: lift is NOT caused by downwash behind the wing, but rather the pressure difference above and below the wing that causes the lift force over the area of the wing. It is correct that the downwash does provide an equal and opposite force reaction pair to help with lift, but those of us studying airfoils know this video misses some crucial details like those explained above. Additionally, if lift was only caused by downwash as was surmised, there would be a moment caused by the downwash force at the back of the wing that would rip off the flaps or cause the plane to tilt forwards. Thankfully, downwash isn’t the main force. Fluid flow causing pressure differences produces a center of lift about a third of the way back from the wings leading edge (simplified explanation) leading to a well balanced plane. Flight truly is fascinating!
@@Mobius118 plz explain some more missing points. Also could you elaborate on how would downwash break the flaps at back of wings or cause it to tilt forwards.
@@chinmaybiradar3288 I think the most important thing that they left out is meaning of horizontal stabilizers and pitch trim (small "wings" at the tail.) Because the center of gravity is always in front of the center of lift it will always try to push the aircrafts nose down. Horizontal stabilizers are there to counter that force. They have the same air-foil shape but are installed upside-down because they need to push the tail down not to generate lift. The location for center of gravity ofcourse depends on how the plane is loaded (bags, cargo, mail etc) and how the passengers are seated. The further upfront the COG is located, the higher the angle of attack there needs to be on horizontal stabilizers. Pitch trim is used to turn the entire stabilizer, not just elevators. There are lots of great videos on this subject. Try searching Mentour Pilot or Captain Joe if you are interested about aviation or how aircrafts work.
I think the engineers got the idea of how a plane flies and land from birds. If you're wise enough you will only end up praising God. As any kind of technology is just a copy from God's creation.
I wish I had this video during my undergraduate Avionics degree that I completed in 1991. This video basically covers Aerodynamic 1 and Aircraft stability without the partial derivatives.
@@franchisefred4066 the comment is dumb, probably understood because of the bases in physics, also calculating to safe limits of a plane truly needs math

Lesics, I admire your intent here and the video is very well done with a right balance of "keeping it simple" for the grander audience. Unfortunately, though, it is filled with inaccuracies (and I don't mean simplifications, like you did with lift generation, but things that are plain wrong, like during the climb as long and the thrust is greater than the drag the speed will keep increasing, and others) that are not necessary. The video could have been kept equally appealing, beautiful and simple by correcting these things. If you ever happen to see this comment (unlikely) and are interested (unlikely), feel free to reply to this comment (I always monitor my comments for replies).
Having just recently boarded a plane for the first time, i was absolutely amazed by human ingenuity; engineers are among the most intelligent human beings on this earth
It is important to note these mistakes in the video- 1) Flaps are lowered before takeoff even starts. Even as early as directly during are after Pushback from the Gate. 2) The Flaps+Slats are lowered less during takeoff because if they were lowered all the way, it would create too much lift and the Airplane may stall (For anybody who does not know what that means, it means that the weight of the aircraft is becomes to much for the Jet engines and the plane basically falls out of the sky). They are lowered much farther during landing because the low levels of thrust to reduce speed for landing is not enough to keep the airplane in the air so the Flaps+Slats produce enough lift to keep the airplane in the air long enough to get to the Landing Strip. Science
I always wondered about about the principles of physics with Flight Movement since my first flight journey and truly an outstanding contribution by the Engineers to the mankind. Proud to be an Engineer.
Came here because I’m reading a biography of Leonardo Da Vinci. Leo observed how birds fly and the book quickly explained how birds and planes fly. I wanted a visual and deeper explanation and this video greatly illustrates how planes fly. Thanks you for this great video.
In 6:05 he talks of the lift generating `centrifugal force` which is a fictitious force (if he wanted to explain it like this he should have said `centripetal force` instead). He could have just said that a component is pointing to the side which would have been easier to understand. What this shows is that he definitely simplifies things (sometimes oversimplifies them), but still for an average user it is okay. I don't expect a pilot watching this video to neglect his take-off-checklist the next time ;)
Yea, the pilots usually extend the flaps and slat right after pushback or during taxi to the runway. But I get it, he's trying to show how the parts work during flight.
I was taught that the airfoil shape of the wing causes air going over the top of the wing to go faster than the air underneath. This low pressure causes the wing to lift up. Take two pieces of paper and hold them parallel in front of you hanging from your fingers and about 2 inches apart and blow between theme. The air passing between them causes low pressure that causes the papers to be pulled together, not apart. That's the wing principle. Wings are PULLED upwards not PUSHED.
A flow accelerates when it experiences a convex curvature. As the upper surface has more curvature the flow is accelerated more than the lower surface, causing suction.
I've never realised how amazing aeroplanes are, just how they work is so fascinating ! I wanted to know how planes fly, and this was extra amazing! Thanks so much for explaining, and just how planes are even made are even more amazing. Thanks so muchhhh
I live in a place where the planes landing and taking off from Chandigarh airport always flyover. I have also flown many times, national and international. But I had always wondered how the engine power was transferred to the wings and how it kept the plane afloat. Everything very clearly explained in this short video. Thank you.

3:42: pilots don’t extend flaps during the takeoff roll, they would extended it way before that (it’s in their checklists more than once just to be safe) - if they started their roll without the flaps they would get a takeoff config warning for which, if I’m not mistaken, the answer is to reject the takeoff.
Precisely narrated in a very good accent of English Vinglish so that I could’ve manage to understand 50% and the rest found in guess work. Worthy video no doubts. Thanks 🙏🏻
A plane is an aircraft that is powered by engines and propelled through the air by its wings. It is able to stay in the air due to four forces: lift, weight, thrust, and drag. Lift is generated by the wings as air passes over them, and is greater than the weight of the plane. Thrust is generated by the engines and pushes the plane forward. Drag is created by air resistance as the plane moves through it, and opposes thrust. The different parts of a plane include the fuselage, wings, tail, engines, landing gear, and control surfaces. The fuselage is the main body of the aircraft and houses passengers and cargo. The wings are attached to either side of the fuselage and generate lift. The tail provides stability to the aircraft and helps it turn. The engines provide thrust to propel the plane forward. The landing gear allows for takeoffs and landings on runways. The control surfaces are located on the wings and tail and allow for steering in all directions.
I found the use of elevators, located on the back wing, near the tail, as just the missing part in my understanding of how the planes lift up the ground during take-off. Thanks for the nice explanation.
Neat video! These basic principals apply to all airplanes, from a styrofoam RC plane, to a Boeing 787 (in the video)! A couple nit-picky corrections; airliners use flaps to increase lift at low airspeeds for takeoff and landing. They bring the flaps up when they get going fast enough. The flaps are extended before the plane even gets to the runway, not during the takeoff roll. In a turn, we neutralize the ailerons once we get to the desired bank angle, and then have to actively roll the opposite direction to stop the turn. As shown, lift is split into a horizontal and vertical component. The vertical component is reduced in a turn, so we also have to use up elevator to increase AOA and keep from descending. This results in a G load depending on how steep the bank is.
@@epicgamer9295 the Palme in the vid is a 787-8 bc of the nose, cockpit window shaggy was saying this so he can say that since he watched this vid helped him understand how a plane shaggy mentioned (737 max witch is dead) and the 787in the vid
Thank you for this, now I know that the yokes or joysticks doesn't move the whole plane but instead they only control the ailerons and elevators that moves the whole plane
Literally always wondered every time I’m flying, just got off a flight yesterday flying from three different airports and wondered how these jets lift off and fly in the air.
This is really more of importance especially to the under activation OR those whose passion is aircraft engineering....Am also one of them and am actually going to start on my practicals soon in December (if all goes well)....and I would kindly request for friendship From any of you especially the air craft engineers and my fellow who could have the same inspiration
thank you so much... it was literally a huge help... and the explanation was so smooth that a baby would easily understand the physics behind it and generate an interest in science and physics
@@antoniomontana5778 the more I see what science can do the more I believe in magic lol, take for example the phone I'm typing this from, it's like a mini computer more powerful than the first computer that took up a whole room.
@@unknownx7252 I am a first hand witness to that!!! When I was in college, there were no cellphones or internet. I had to do my computer projects at the mainframe computer in school, because my PC didn't have enough space in its harddrive to install the COBOL language I needed to write my programs. At that time, we talked kilobytes, just imagine!!!
5:40 Centripetal Force, there is no such thing as a centrifugal force. "Centrifugal Force" is a fictitious idea that is used to describe the apparent outward force on an object in radial motion. Centripetal force is the actual force that causes an object to travel in an arc.
You're right, I was about to point this out as well. Centripetal force is the force that makes an object travel in a circle. It will be the normal to the plane's direction of flight, towards the centre of the arc/circle, the plane is turning. In this case they used the wrong term.
"there is no such thing as a centrifugal force" xkcd.com/123/ Centrifugal force is just as fictitious as gravitational force is. Just because it is fictitious doesn't mean it can't be used to describe something. But the video is definitely wrong in this case, what they show is indeed centripetal force.
@@TheAngelsHaveThePhoneBox Newtonian gravity is a generally accepted approximation since the objects are not traveling anywhere near the speed of light, centrifugal force is completely inaccurate.
@@Boss_Tanaka ahh yea, I was referring to a ideal scenario. Any plane would be able to lift without flaps/slats as long as there's sufficient runway to attain V1 and V-climb speeds providing the environment supports it :)
It's "Fundamentally" Simple to Explain!!! As a child, I used to play "Birdie" while the car was moving. I'd stick my hand outside the window, and then notice that the wind would "effortlessly" "SUSPEND" my Hand and Arm, and they'd literally be "Surfing-the-Wind." While parallel to the ground, my hand would just cut thru the wind; however, the slightest adjustment in "Angle-Up" would send my hand "Soaring," and the slightest adjustment in "Angle-Down," would send my hand "Diving." Eventually my whole arm would fly back if I'd increase the angle and expose enough of my Under-Arm's "Surface Area" to the wind - and same for my Over-Arm. I truly believe it has to do with "Wind Speed," "Surface Area," and simply which surface the air is coming into contact with "More." So as the plane angles up, fast flowing air is hitting the underside of the plane's Wing-and-UnderBelly "Surface Area," then "Lift"ing the plane "Upward." The Weight of the Plane actually smooths out the erratic "Birdie-Hand" movements, while "Angling" Up or Down, and makes for a much smoother ride (which also explains why smaller planes have a more "turbulent" ride). The powerful "Thrusters," in turn, overcomes the Force of Gravity acting on the weight of the plane. What is termed "Lift" is actually "Air-Bouyancy." Bouyancy is a naturally occuring property of Air with enough Thrust & Surface Area -as demonstrated with the "Birdie-Hand" SUSPENSION. Physics simply works out how much more (ie Wind Speed, Surface Area, & Thrust) is needed to Lift a "Plane" over, say, a "Birdie-Hand."
Extend the flaps before you roatate and the chief pilot you'll see.-- Yoda The config warning will bark at you if you don't extend the flaps before 15° TLA.
This is the most important video for me and such a wonderfull video that I have not ever watched before.....

Thanks for quenching my curiosity.
I'm at a 6 hour layover thank you for entertaining me for 10 minutes
Precisely narrated in a very good accent of English Vinglish so that I could’ve manage to understand 50% and the rest found in guess work.
Worthy video no doubts.
Thanks 🙏🏻
Very interesting... i have been rewinding and replay as many times as i could to have a better understanding. Greetings from Namibia Windhoek.
*Very interesting I had to rewind and play the video again and again to understand more thank you!*
I'm confused why people don't understand I'm just a 10 year old and I already know about this
@@crowyxl1563 Thank your God for making you a bright boy😊
Thank you🤗
I want to say thank you for your amazing work. This is really astonishing.
I would not fly on a plane if the pilot had that haircut
A plane is an aircraft that is powered by engines and propelled through the air by its wings. It is able to stay in the air due to four forces: lift, weight, thrust, and drag. Lift is generated by the wings as air passes over them, and is greater than the weight of the plane. Thrust is generated by the engines and pushes the plane forward. Drag is created by air resistance as the plane moves through it, and opposes thrust.
The different parts of a plane include the fuselage, wings, tail, engines, landing gear, and control surfaces. The fuselage is the main body of the aircraft and houses passengers and cargo. The wings are attached to either side of the fuselage and generate lift. The tail provides stability to the aircraft and helps it turn. The engines provide thrust to propel the plane forward. The landing gear allows for takeoffs and landings on runways. The control surfaces are located on the wings and tail and allow for steering in all directions.
Fly by wire is a great technology. If added more CFD simulations this would be more informative. Specially of wings
Thank you-I learned something about flight when it comes to jetliners!
I found the use of elevators, located on the back wing, near the tail, as just the missing part in my understanding of how the planes lift up the ground during take-off. Thanks for the nice explanation.
ultra realistic flap demonstration and amazing tailstrike
Neat video! These basic principals apply to all airplanes, from a styrofoam RC plane, to a Boeing 787 (in the video)!
A couple nit-picky corrections; airliners use flaps to increase lift at low airspeeds for takeoff and landing. They bring the flaps up when they get going fast enough.
The flaps are extended before the plane even gets to the runway, not during the takeoff roll.
In a turn, we neutralize the ailerons once we get to the desired bank angle, and then have to actively roll the opposite direction to stop the turn.
As shown, lift is split into a horizontal and vertical component. The vertical component is reduced in a turn, so we also have to use up elevator to increase AOA and keep from descending. This results in a G load depending on how steep the bank is.
Thanks for sharing. It increased my knowledge.
shamayal ramay same here bro i was so interested and i find this usefull
Can you please kindly tell me the barber’s name and address that had given the pilot that haircut? That fade is on point! 👌🏼😂
😆😆😆😆
This makes me proud to be a human
Feking joke XD
Best flying video ever 👍🏻👍🏻
Beautiful explanations...👌
Thanks for the tutorial. I'm ready to fly a 737 Max 8.
MCAS has entered the chat
isn't it 787 though
Lol
@@epicgamer9295 the Palme in the vid is a 787-8 bc of the nose, cockpit window shaggy was saying this so he can say that since he watched this vid helped him understand how a plane shaggy mentioned (737 max witch is dead) and the 787in the vid
@@ayumiyamaguchi3773 oo thanks for the clarification
Thank you for this, now I know that the yokes or joysticks doesn't move the whole plane but instead they only control the ailerons and elevators that moves the whole plane
Literally always wondered every time I’m flying, just got off a flight yesterday flying from three different airports and wondered how these jets lift off and fly in the air.
This is really more of importance especially to the under activation OR those whose passion is aircraft engineering....Am also one of them and am actually going to start on my practicals soon in December (if all goes well)....and I would kindly request for friendship From any of you especially the air craft engineers and my fellow who could have the same inspiration
Every video is of Million Dollars. Perfect video and perfect explanation👌👌👌
So... Magic. The answer is magic.
*Imagination*
Physics + thermodynamics + more stuff
Well, aerodynamics
İt exactly was thing what I wanted. Thanks for your explains its so useful, good work .
THIS VIDEO is MAGICAL 😄🌬📚lol thank you indeed
Magical?
What do you know about magic, Muggle?
I was amazed after watching this video... with simple techniques the flights are flying
hats off to the engineers ...🛩🛩🛫🛫
thank you so much... it was literally a huge help... and the explanation was so smooth that a baby would easily understand the physics behind it and generate an interest in science and physics
Basically, it's a kind of magic -- like everything else in the universe.
not really but i would agree
It's called SCIENCE!!!
Did you see any magic at all? NO.
@@antoniomontana5778 the more I see what science can do the more I believe in magic lol, take for example the phone I'm typing this from, it's like a mini computer more powerful than the first computer that took up a whole room.
@@unknownx7252 I am a first hand witness to that!!! When I was in college, there were no cellphones or internet. I had to do my computer projects at the mainframe computer in school, because my PC didn't have enough space in its harddrive to install the COBOL language I needed to write my programs.
At that time, we talked kilobytes, just imagine!!!
5:40 Centripetal Force, there is no such thing as a centrifugal force. "Centrifugal Force" is a fictitious idea that is used to describe the apparent outward force on an object in radial motion. Centripetal force is the actual force that causes an object to travel in an arc.
Doesn't matter as long it's consistent and useful.
Gravity is a fictitious force. Curvature of space cause two object to move towards each other. So gravity is not real.
You're right, I was about to point this out as well. Centripetal force is the force that makes an object travel in a circle. It will be the normal to the plane's direction of flight, towards the centre of the arc/circle, the plane is turning. In this case they used the wrong term.
"there is no such thing as a centrifugal force"
xkcd.com/123/
Centrifugal force is just as fictitious as gravitational force is. Just because it is fictitious doesn't mean it can't be used to describe something. But the video is definitely wrong in this case, what they show is indeed centripetal force.
@@TheAngelsHaveThePhoneBox Newtonian gravity is a generally accepted approximation since the objects are not traveling anywhere near the speed of light, centrifugal force is completely inaccurate.
A small but crucial correction at 3:41, the slats & flaps are extended before the takeoff roll.
Not all the time ruclips.net/video/fBKpi0PwBd4/видео.html
@@Boss_Tanaka ahh yea, I was referring to a ideal scenario. Any plane would be able to lift without flaps/slats as long as there's sufficient runway to attain V1 and V-climb speeds providing the environment supports it :)
Great video, just saw this before my first intro to aerospace science class hahahha
You guys are doing amazing animations.
Flaps are applied before you are on the runway
Please make a video about how a computer works .. Or make a series. .
This was enjoyable to learn. I love flying and recently took a trip from Seattle to Indianapolis and back. Thank you for sharing.
Amazing 🤩 finally I understand how an aircraft flies! It's truly an engineering Marvel!!!
Your presentation your presentation is highly interesting to watch. Thank you very much and take care.
This kind of things made me fall in love with Engineering ❤️
5:35 Additionally, swaying the rudder too much will cause the tail to break off, which would cause the aircraft to crash
Which pretty much happened to American Airlines flight 587.
While i was in aircrew training, i did a simulation to try to actually fly the plane. lmaoooo i suuucked ass. Pilots have impeccable precision lol
Wow, they teach stewardess how to fly? WTF, didn't know this was a thing - must be some new requirements.
Amazing illustration and explanation. Thank you!
It's "Fundamentally" Simple to Explain!!!
As a child, I used to play "Birdie" while the car was moving.
I'd stick my hand outside the window, and then notice that
the wind would "effortlessly" "SUSPEND" my Hand and Arm,
and they'd literally be "Surfing-the-Wind."
While parallel to the ground, my hand would just cut thru the wind;
however, the slightest adjustment in "Angle-Up" would send my hand "Soaring,"
and the slightest adjustment in "Angle-Down," would send my hand "Diving."
Eventually my whole arm would fly back if I'd increase the angle
and expose enough of my Under-Arm's "Surface Area" to the wind
- and same for my Over-Arm.
I truly believe it has to do with "Wind Speed," "Surface Area," and simply which surface
the air is coming into contact with "More."
So as the plane angles up, fast flowing air is hitting the underside of the plane's
Wing-and-UnderBelly "Surface Area," then "Lift"ing the plane "Upward."
The Weight of the Plane actually smooths out the erratic "Birdie-Hand" movements,
while "Angling" Up or Down, and makes for a much smoother ride
(which also explains why smaller planes have a more "turbulent" ride).
The powerful "Thrusters," in turn, overcomes the Force of Gravity acting on the weight
of the plane.
What is termed "Lift" is actually "Air-Bouyancy."
Bouyancy is a naturally occuring property of Air with enough Thrust & Surface Area
-as demonstrated with the "Birdie-Hand" SUSPENSION.
Physics simply works out how much more (ie Wind Speed, Surface Area, & Thrust)
is needed to Lift a "Plane" over, say, a "Birdie-Hand."
Top marks for such informative video. It answered questions I had about the Airfoil and reverse thrust. Well done.
This amazing human power of thinking 💭💪🏽 Love this doco ❤️
This is all a really elaborate way to say "plane go up cuz magic"
This is just splendid.. i went from being bewildered to gasping at this masterpiece..👏👏
Best video I've come across till date on GPS.. Understood the concept for the first time after going through multiple videos! Thank you so much!
3:40 lol you don't extend the flaps/slats just moments before pulling up, you already have them adjusted before starting the take-off roll.
Reply you
Extend the flaps before you roatate and the chief pilot you'll see.-- Yoda
The config warning will bark at you if you don't extend the flaps before 15° TLA.
No flaps no fly. the check list first step is visual then flaps.
Everyone:This man is too inteligent to be left alive
Appreciation to the modern scientists who makes some scientific principles works wonderfully in aircraft.
மனிதன் கண்டுபிடித்த மிக பெரிய அதிசயம் ஆச்சரியம்.. விமானம். அனைத்து பொறியாளர் க்கும் பாராட்டுகள்
Thank you for knowledge. 😊
I always assumed it had something to do with the wings.
This is the most important video for me and such a wonderfull video that I have not ever watched before..... My future goal is to become a fighter pilot in Pakistan Air Force so this is too muxh important for me to know how the planes able to do successful flights.... I've a request to #Learn Engineer's admins upload a video for a fighter jet that how does it fly ? almost everything about it......... I shall be very thankful to you.
Abdullah khalil Nice
@@Cheesegoose3 thank you dear
This helps a lot with my anxiety. Really scared of flying
i really enjoyed it. next time i go travel, i will pick a window seat and observe the wings
