    when I was a youth, I remember reading in the 70's an article in Popular Science... about these new winglets that were going to be on EVERY plane...we;;, here we are!

    I estimate the winglet to be about 2 ~ 2.5 metres in height

    When will the bigger winglets get their own winglets?

    My guess, about 3/4 your height, maybe 1/2. Of course with double winglets now in use I can't even remember well enough to make a guess.
    I have heard that when one of those downward winglets is hit by a vehicle the repair costs $1 million. I then to think that's an exaggeration but we shall see.

    [Edit. I made a bad guess. Those winglets are remarkably large. I travel twice a year and with SW it's always a 737. I sit at the back on the shady side to take pictures but always on the left side when landing in San Diego so I can watch the buildings go by.] [Second Edit. I am a physicist so I knew the purpose of those winglets when I first saw them].

    Very insteresting explanation, answering some questions bothering me for a very long time; when I was a child in the 60s it was natural for my siblings and I to make paper-airplanes, our goal was to make them fly as far as possible, so we started bending the tip of the wings, we discoverd these wing-tips added stability to these paper-planes, letting them to fly in straight line easier and reaching long distances, when I notice the industry introducing wing tip in the 70s I was amused, but until today I did not know the reasons, thanks for your video, I love them.

    Wow. I don't know why this reality got their engines protruding out front. But i think the winglets are neat. I'm glad the mandela effect recently changed all the planes but I hope the engines go back to the original position towards the back of the wings. My reality had more common sense

    cut the shit. Everyone knows they stop the plane from skidding all over the place above fucking Brussels , or the kremlin or chicago. i know these things mate, trust me. i dont need to no wings on my fairy girl white shirt mate. im good, im real good. I know shit about flying. im real exeperienced ive flown to many countries like Africa, the country of Europe, fiji, ive flown to fiji, america. Normally as a passenger. So dont tell me i know nothing

    Does it also prevent vortices from pulling the air above the wing (outer section) spanwise which could result in wing stalls at lower speds like landing?

    You see that huge vortice on a flat wingtip ? The aircraft has to expend energy to drag it along its entire flight. That's a lot of energy (fuel) !

  • Amlan Gupta

    Captain, only a private pilot and too old to make a living flying, but loving your videos. I'm curious why some airlines are retrofitting winglets now? For example, Air Canada Rouge is doing so on their 767's but not on the mainline Air Canada ones. I'm presuming it has to do with newer materials making the winglets worthwhile but only on longer ranges which is what I believe Rouge typically does?

    Why haven't they fixed proportional winglets to the horizontal stabilizers as well?

    • Mark Lewis
      Mark Lewis 19 days ago

      I have a little experience with aircraft, and I always wondered the same thing.
      My best guess is that the horizontal stabilisers aren't really there to generate lift (in fact, if you look at the foil profile, it's "upside down" on most, if not all standard layout aircraft), so they're used as a control surface, rather than a lift generating device. I'd say any efficiency gained wouldn't be significant enough to warrant the development and certification required. Just my opinion anyway.

  • Tony G

    I'm not going to watch the video. Winglets let you lengthen your wingspan without having to make your aircraft wider.
    Making them wider would increase the necessary widths of runways as well as docking stations. We want to avoid the cost/space requirements for that. (Duh!)
    Increasing the wingspan deceases the overall drag. We DO want that. (Duh!)
    Maybe increase the wing length, but do it on a tangent?
    If you can't follow, get used to asking, 'You want fries with that?'

    So that's why the US Navy's new 737 based maritime patrol aircraft, the P-8 Poseidon, has the cranked wingtips instead of winglets.
