    I’m also a wing structures mechanic and I help build the 737 wings it’s an amazing piece of engineering, if it doesn’t have wings it’s just a bus

    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.

    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.

    Hey Mentour, awesome videos! When you touch down do the slats and ground spoiler come out automatically? Is it a weight on wheels thing or must they be selected?

    I did read of an accident where both pilots failed to set flap/ slat setting on the aircraft causing a stall on takeoff and crashed. The flight recorder confermed this..check list allways.

    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.

    Sometimes, when a plane taxis after landing, I notice that the flaps start to retract, then pause, then continue to flaps 0. Why do the flaps sometimes pause insiead of going from full directly to 0?

    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!

    Great channel. One question . What are the purpose of those wheels turning when you were selecting flaps ?

  • Andrej Podzimek
    Andrej Podzimek 6 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 6 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!"

    Also, a byproduct of flaps 30 or 40 is increased drag and therefore higher engine rpm. This facilitates quicker engine spool-up to go-around thrust in case of a missed approach.

    I have wondered how the winds are factored in slot/flap selection? Straight headwinds versus a crosswind component. I have student time in a 172, a Warrior II, and a Grumman Tiger, but no heavy tin. I have no aspirations either, but I am curious. We had a trim wheel to "Trim" out the yoke. I have also wondered about the numbers on the flap lever. Do the numbers, 1, 2, 5, 10 and so on, what do they correlate with? Are they angle degrees or are they just identifiers for your company? As a very interested frequent passenger, I am just interested. Keep them coming Capt.
