Winglets – What are those things on the aircraft wing-tip?


I have a referral to mentor a fella video folk dancers always I’ll be doing absolutely fantastic today on the podcast hours we’re gonna be talking about winglets why are there so many types of them why do they look like they do what is the purpose of them so stay tuned hi guys so today we are going to be talking about winglets and the first thing I’m gonna say if you stay tuned I have a question for you okay so I want you to write in your answer in the in the comments below now before the end of the video how high do you think a 77 winglet is compared to me alright write in your answer right now okay this video is brought to you in cooperation with brilliant org brilliant rhetoric is a website that will help you fine-tune and perfect your math skills and your physics skills which is something you might well need before your pilot interview check out the link below right guys so wing nuts what are they well first of all if you’ve been travelling as a passenger you probably notice if you’ve been flying on more modern aircraft recently that if you look out to the wing you’ll see that the wing tip tends to be kind of curved upwards now they look different on different aircraft types so if you’ve been flying for example on an Airbus 320 of an older model you would have seen the very simple kind of wingtip fence type that they had if you’ve been flying on a 77 new generation you would have seen the sharklet which basically looks like a like a shark fin sticking up and on the very new 737 max we have something called a split scimitar winglets okay now they all work from the same type of principle and it all the reason that they came in the first place was in order to find that out you have to go back a little bit in history which I have a tendency to do so the first types of 737s they did not have any winglets at all okay the 77 100 and 200 did not have any winglets and could not be retrofitted winglets either they were made in the 60s and in the mid 70s due due to some geopolitical crisis the fuel price suddenly started rising the oil price started rising and with that the aircraft manufacturers started looking into how to make their aircraft more efficient more fuel efficient now a Boeing they turned to NASA and specifically to a NASA engineer Corps Richard Whitcomb now Richard Whitcomb he had been looking at ways that the birds were flying and he was specifically looking into how Eagles were flying and he noticed that the the feathers on the wingtips of the Eagles tended to Bend upwards as they were soaring okay and he wondered why that was so what he looked into is how an AB wing is creating lift in the first place now you know to understand this you have to understand that as of wing is taking out lift the more lift it’s taken out it’s normally because it’s angled towards the oncoming wind and also because of the shape or doing now as it takes more lift out what it does it is creating a high pressure on the lower part of the wing and low pressure on the top part of the wing now whenever you have that happening in nature whenever there’s a difference in pressure the nature will always try to equalize that pressure difference so what happens in the case of a wing is that air tries to escape from the lower part of the wing to the top part of the wing and that happens at the wingtips now that creates big vortices now you might have seen these vortexes if you seen aircraft landing when it’s really moist outside you can actually see these wingtip vortexes happen and when a vortex is is created it actually steals energy away from the aircraft and it reduces the lift that the aircraft I can take out so Richard Whitcomb started looking into ways to solve this and what he came up with was let’s do like the Eagles nature have a tendency to do things in the most efficient way possible so he created a kind of offense which is what a winglet essentially is all right so he bent the wing tips up and notice quite quickly you get a much higher efficiency out of the wings while doing that so anyway there are different ways of doing this because the thing is anytime you add something onto an aircraft you also add weight and in case of winglets since you are putting these wingtips winglets on at the tip of the wings they’re also going to create a little bit of torque okay that will have an effect on the structure and structural integrity of the wing so you have to strengthen the wings and that also cost weight and this means that in order for you to on order for the winglets to be efficient they have to be more efficient than the this you know the negative effect that the extra weight hath and that’s this increases with the length of the flight okay so if you’re doing really short hops with a very short cruise it means that winglets might not necessarily be of any help but if you’re doing longer flight they become more and more efficient and this is what Airbus noticed so on the first Airbus 320s and 319 s Airbus basically said well what we’re going to do is we’re going to fit this really really simple wing tip kind of fences right you might have seen them which are really just a very very simple piece of plastic that is stopping some of the intakes for Texas from happening because we want to save on weight and we don’t think that this is going to be efficient but after they went into this at the Airbus 320 Neos they actually found ways of reducing the overall weight of the aircraft and by doing so they could fit the very similar shortcuts to their air buses which would also increase the overall efficiency now if you don’t go into the 737 max series they have something called a split scimitar so the efficiency that you get out of a normal sharklet okay is on ie on a flight that’s about 500 nautical miles you will game about 1% of efficiency on a flight that is about 3,000 nautical miles you will gain as much as 3 in half for maybe 4 and a half percent efficiency now the split scimitars works exactly the same they’re just stopping the air from escaping both on the top and the bottom side and according to Boeing it increases the overall efficiency of the aircraft with another one and a half percent and it adds about 65 nautical miles to the range and that’s very very important because as you might have seen the low-cost carriers are now trans you know flying over the Atlantic with 737s they couldn’t do that before and it has partially to do with this new winglets other benefits that you get from winglets is as the aircraft gets left dragon gets more efficient it means that for example during takeoff they can use less thrust and when you’re using less trust during takeoff it’s less noise there’s less pollution and there’s also a lower maintenance interval on the engines so the saving is not only on fuel burn but it’s also on maintenance intervals noise punitive costs things like that so there are many many many benefits from increase in the efficiency and the wing length is part of that solution now you might ask yourself okay so if these wing lists are so fantastic why aren’t they fitted for example to the 787 which is the most new and most efficient aircraft in the Boeing family well when it came to the 787 Boeing actually looked into the 767 wings and the 767 wing has something called a raked wing tip that means that the tip of the wing is is kind of angled slightly backwards and slightly upward and what they found out that if you’re flying really long-haul flights as in ultra long-haul flight The Rape wing tip is actually even more effective on the overall fuel burn than a fitted winglet would be now the Airbus 350 has these new wing nuts okay so you’ve seen them they’re very very peculiar they’re very curved so they have chosen to go with winglets on their models so that leads me to believe that it is possible that the difference between these two wings probably is not that big okay because they are so efficient now that they’re there probe you know close in on what is possible to do aerodynamically anyway so that’s what I had to say about winglets I hope that makes a little bit more sense to you now and as always guys make sure that you get the mentor aviation app right mentor aviation app is available here if you just go down and you click the links both for Android and for iOS you can get the apps completely for free and you can talk to me and you can talk to other aviation enthusiasts and you can watch videos about aviation it’s it’s a lot of great people in there that just dying to talk to you guys um I want you to check out my sponsor and the brilliant aunt org if you go in here and you click this link below you’ll be able to go in and you they actually make it quite fun to learn maths and physics and it might be good for you to do before you go for your flight school interview now I did promise you to show you the difference in height and high you know if you put me up next to a 737 shortcut so here it is this is the answer to your question now be honest is it bigger or smaller than you thought it would be that’s what I thought guys I’m going to continue to do this series on particulars on peculiar things on the 737 so make sure you stay tuned and I’ll just to show to you by the way that this is not the green screen I’m gonna be running into the distance now so see you next week guys bye bye [Music]

    Winglets are also much safer. Some of the vortices created by heavy and slow aircraft can be extremely powerful and even push other planes out of the sky (if they happen to be in the path of the vortex). Winglets help greatly reduce the vortex (as Mentour said), by giving a place for the high pressure and low pressure air to meet gradually (instead of a big column of high pressure air twisting over the edge of the wing as it tries to fill the low pressure area).

    The recent Qantas incident from last week in LA resulted because the plane was hit by the wake vortex from the taking off aircraft ahead of them. Aside from that, there have been many accidents attributed to wind vortices, both big and small aircraft.

  5. Hangfried says:

    One yard, or meter?

    I was kinda surprised how he is not scared of him standing at the road of airplanes 😲👀

  9. stapakropoz says:

    I'd say they're probably about 9 feet tall? Or maybe it depends on the size of the aircraft and wings?

  10. Zibbe Zabba says:

    same height?

  11. Mud Therapy NC says:

    that ending of running away was gay AF

  12. Kouga says:

    Before watching: Winglets reduce wake-vortices which in turn reduces drag -> great for airlines because less drag means less fuel consumption, the largest of airline costs. Boo-yah!

    i think as tall as you are

  41. J C says:

    Just a guess, but I'm going to say the winglet is the same height as you

  42. Isaac Puga says:

    2 times you

    Not only fuel efficiency but it looks also the aircraft nicer

  44. Randy L. says:

    6’ tall

  45. JayJay Aviation says:

    8 feet

  46. Robert Tracy says:

    The nazis put winglets on one of their aircraft the he-162 but instead the winglets pointed downward on one of the many wing designs

  47. Avican Training Academy says:

    A plane is pretty big. I think winglets are the same or even higher then a person. 7 or 8 feet

  48. Martin Nyamukondiwa says:

    2 metres

  49. brown-eyed man says:

    2 meters


    And there’s me thinking that it was just for fashion.

  51. Daniel M says:

    Airbus not only did the "fence" for the lower weight but b/c the wing root could not handle that much more lift. That's also why some planes cannot be retrofitted

  52. jeannine grant says:

    Cunards keep planes from sliding. Sideways in the air

  53. Samuel's Simulations says:

    Mentour: Makes a video about winglets
    Intro: Uses a Boeing 777

  54. Samuel's Simulations says:

    10:27 this cracked me up so much!

  55. Mike Becket says:

    Reduces drag ..

  56. Ruben Götz says:

    I would guess its taller than you, maybe like 2,20 m

  57. ZimmMr says:

    Watching without volume mad it look like a cool dance😄

  58. HauntedShadowsLegacy says:

    If you think Mentour holding his arms out like wings as he runs ISN'T adorable, you're heartless and need to rethink your life.

  59. Otto Hans Nitsch says:

    The winglet is about 2,70 meters high.

  60. plassh pro says:

    Hey are you from sweden i love your videos you are the best

  61. plassh pro says:

    Ar you from sweden i think it is 1m

  62. Michael Petzold says:

    Just a design to make the plane look cool that's all

  63. Barry A says:

    Six times

    Captain Mentour Pilot the preferred plural of vortex is VORTICES rather than vortexes when applied to Aerodynamics in the English Language….just a constructive comment Sir !

  67. Juan Carlos Vella Fenech says:

    As high as you sir

  68. Frankie Roberts says:

    Winglets are for balance when landing

    Just l can thank you very much for my knowledge

  71. Buddy Wiser says:


  72. Alessandro Bautista says:

    Winglets from your feet to your belly button that's how Hi I think they are

  73. Alessandro Bautista says:

    I thought the winglets were going to be way smaller

  74. Esa Espoosta says:


  75. Slicedthrower64 -Roblox says:

    There are for aerodynamics

  76. MAIZ GAMING says:

    Just above you head

  77. Wall Cutter says:

    WRONG. It's actually the cruise control flap. You access it through the bottom of the hull… Then climb through the wing….very uncomfortable…..yes but it has to be done if you want to take your foot of the accelerator.
    37 feet tall compared to you

  78. Kleeneze Stu says:

    About your height

  79. Bogdan Todchuk says:

    Half of your height

    oh sith

  81. Bob Cloud says:

    Winglets are 6' in ht.

  82. david carder says:

    I think it's horseshit.never seen one on any fighter jet.and Yes, been there done that.

  83. hhhm.1 says:

    My guess is that the winglets are about 7ft???

  84. Joe Markes says:

    8 feet

  85. ArchitectPage says:

    winglets were first on Hanley Page Victors early 50ies

  86. Bruce Nitroxpro says:

    Guess? Maybe up to your waist?

  87. jonespvp 575 says:

    Probably about 2 times your hight

  88. John Barron says:

    I'm going to guess… winglet is 50 centimeters taller than you.

  89. Preston Thomas says:


  90. Nina Bella says:

    1,5 mt ?

  91. Fat Albert says:

    To stabilize the aircraft as it decelerates, to minimize "rocking"?

  92. Wai Ming Kar says:


  93. Mark Frabotta says:

    There about 11 ft tall..

  94. Simon Mcgrath says:

    Sir I must say I've subscribed to ur channel cuz it's a brilliant channel and very interesting and I love all the facts thanx

  95. SAMI BARHAM says:

    Man you need to talk slower than this well be better to keep up toooo fast is not good

  96. Bad Cattitude says:

    I thought winglets were just baby wings. I imagined there would be like an airplane nursery somewhere with little baby 737s fluttering around and learning how to be airplanes

  97. RealyRandomStudio Savage says:

    thats a hella skinny runway,

  98. Wankel Motor says:

    The Long-EZ rocking winglets before it was cool…

  99. DN Rao says:

    12 feet

  100. Jeff Hannie says:

    8 foot tall on a 737
