  • In this episode I will explain the purpose and function of the high-lift devices fitted on the Boeing 737NG. I will explain and show you how they work, when we use them and why.
    I really hope you will enjoy this one and if you do, I will follow up with more in-depth procedures in upcoming videos.

    Imagine taking venetian blinds that are rolled up, and putting them rolled up , rod and all, on your shoulders and running into the wind on a fairly windy day. Now unroll the venetian blinds out about half way and run into the wind again. OK, next let the venetian blinds all the way out and hold them on your shoulders. Now it will look like you are holding some big vinyl cape cape on your back or something. Now start running into the wind with the blinds fully extended like that. Don't let go because there will be MORE DRAG trying to pull the rod out of your hands than the first time you ran with the blinds fully rolled up.

    What is the difference between pylons and nacelle ?

    • Coby Explanes
      Coby Explanes महीने पहले

      Hey Aman, the pylon is the rigid structure used to hold the engine in its place and position under the wing, without interfering with the airflow over and under the aircraft wing that is needed for lift and control. The nacelle is essentially the engine casing, used to shield internal components from debris and the elements. Hope that makes sense! If you've got more questions like these, head on over to my channel and subscribe! Addressing these sorts of questions is kinda my thing :)

    So, if higher flaps may be appropriate for short field TO, but flaps add drag, is there ever a case for starting the roll with low flaps to build airspeed more quickly, then selecting higher flaps to gain required lift?

  • thomshart
    thomshart 3 महीने पहले

    Hi. Mentour. Just curious, since flap is needed to create lift when on runway, why the flaps has already down when the plane is still on the taxiway.

  • Charles Dominguez

    If flaps create a drag for the plane to slow down then what do air brakes do? What exactly is the difference?

    It’s hard to believe this guy after he said that the role of reverse thrust is to cool the brakes and has nothing to do with slowing the aircraft . Hello , reverse thrust is used to decelerate.

  • Kenneth Hoffman
    Kenneth Hoffman 4 महीने पहले

    This might sound simplistic, but I've always likened the need for and use of high lift devices as being similar to a manual transmission on an automobile. It's a way of 'switching gears' on a wing so you can control speed and yet still get adequate lift at a given speed. When you take off, you put the wing in 'low gear' to get the required lift at the relatively slow speed at takeoff. Once you are up and away, you begin to 'shift gears' higher by reducing the high lift devices until the speed is adequate to discontinue their use. The opposite is true when descending. Similar to descending a hill in an automobile, you need to reduce speed and thus need to 'downshift' the wing to incrementally obtain the desired speed reduction in a controlled way, and not get into trouble with lift.

    I once saw a magazine called Flaps... It wasn't about planes though.

  • Gerard Moran

    Nice instructive video! There are two points I'd like to mention. The increased drag of landing flaps are important to make steep approaches if you're flying a Cherokee or Twin Otter in mountainous terrain but most transport jets don't fly those profiles. We all (airliners) need to be at about 1000' at 3 miles. Early turbojet engines needed a lot of time to spool up to go-around thrust and the higher drag meant higher stable thrust on approach. Engineers built in high drag for that reason. This greatly reduces spool up time to go-around thrust. In fact some early turbojets (think 707, 727) were so slow to spool up you were basically committed to land once below 400' unless your power was up. Modern turbofans are better but the design concept remains. Lastly, at Delta we illuminate all lights (landing, wing, nacelle and runway turn-off) below 18,000' to maximize our visual impact. Perhaps it's because there's more general aviation traffic in the US. At Delta, it was technique, but not procedure to turn on the taxi light when landing clearance was received. "Exterior lights" was a checklist item on the descent check which was done descending through 18,000' which is the max limit for VFR traffic in the US. Each airline has slight variations. Cheers

    What do pilots eat when they're at work and what airline are you with? Thanks for explaining the secret code of airline crews because I've always been wondering what those ding dongs mean whenever I listen to videos on INclips where people are traveling and you hear the ding dongs going off. Plus, I was also wondering if pilots can bring their own lunches from home and what do they pack in their bags?Also, where are you from? I've been picking up on your accent and I find your voice soothing. I'm from Nova Scotia Canada and I find your videos interesting because I learn a lot about the airline industry.

    Fantastic information on the flaps, and slats on the plane!
    Just wondering about the pros and cons of a droop vs a slat, and maybe revisiting blown flaps vs slots, or potentially a hybrid flap (My rudimentary understanding is that blown flaps were taken out of regular service due to complexity and mantainence. However, has technology now caught up to warrant a revisit? Active blown flaps seem to be able to create an immediate change in the boundary layer over the aircraft control surfaces, as opposed to the slots, which relies on the surrounding (Injection vs environment))
    Looking forward to you next videos!

  • Andrej Podzimek
    Andrej Podzimek 9 महीने पहले

    A stupid question: Some smaller airliners have their left and right flap mechanisms interconnected with a shaft, so that it‘s impossible to extend or retract flaps asymmetrically (which could, obviously, lead to a crash). But do even the biggest airliners have that mechanical connection between the wings? Or is there a different safety feature that prevents flap asymmetry? How about an A380 or a 747? Is there a flap shaft going all the way through the fuselage and connecting the flap mechanisms?

  • Philippe Lobelle
    Philippe Lobelle 10 महीने पहले

    The slots don’t extend the boundary layer, they blast the boundary layer off. This is done intentionally because, even though it loses a bit of lift, it manages/controls the position of the separation point and thus there is less turbulence.
    The extension of the wing means that there is a much higher likelihood of getting separation of the boundary layer over the wing and without slots this would happen at a random, unknown and possibly ever-changing points. This could drastically decrease the handling of the aircraft as it comes to land.

    From the 1970's when "P. jokes" were popular (99% of the people telling them couldn't find P. on a map). The pilot ask the c/p for flaps, more flaps, and still MORE flaps. They land successfully, & the pilot says, "Man, is this runway short" to which the c/p says, "Yeah, but it sure is wide!"
