    Dear friends and followers, welcome back to my channel!
    To be able to fly, an airplane has to accelerate to high speeds, in order to generate the necessary lift via its wings. This puts huge amounts of kinetic energy in the whole system. Now while being airborne, speed reduction is achieved solely by aerodynamic drag. Once the tires make contact with the runway, other devices such as thrust reversers and brakes mounted on the wheels, help decelerating the aircraft. To put the huge amounts of energy in
    perspective, imagine my 747-8 Freighter with an almost maxed out landing weight of 340t moving at around 155 knots or approximately 290 kph at the moment of touchdown. That’s over 1.1 billion Joule of energy within this moving system! Hard to imagine? That’s the amount of kinetic energy an average car has if it would be travelling at around 4300 kph. Well, good luck handling that one! But back to topic, this energy has then to be converted to
    achieve a speed reduction. The brakes are doing that in form of thermal energy simply known as heat. Modern brakes are packages containing multiple disc brakes made out of carbon fiber. They are mounted at the bottom of the main landing gear suspension. Every wheel has its own set of brakes. Some aircrafts have additional nose wheel braking. To
    activate the breaks, the pilot pushes the rudder pedals with his toes resulting in this tilt movement. The pilot’s input is then transmitted to hydraulic pumps, powering the brakes. The harder you push, the harder you’ll brake. The pedals themselves can tilt independently, allowing the so-called differential braking, which enables better
    steering and maneuvering. The whole process of braking after the touchdown can also be done fully automatic with no initial brake input by the pilot, but more about that in a future video. Let´s have a closer look on the wheel behavior while braking. The brake discs are separated by so called stator plates. While braking the whole assembly is hydraulically compressed, causing friction between the discs and the stators, resulting in a reduction of the wheels rotational speed. In theory, to minimize the braking distance, brake pressure is constantly increased while in return, the wheel speed decreases. In reality it doesn’t quite work like that. Wheel braking in general works in a way that incorporates slip in our
    movement. 10% slip for example means that while the airplane covers 10 meters, the wheels only roll off a distance of 9 meters. This result is braking action. When the brake pressure reaches its maximum the slip reaches 100%, causing the wheels to lock. The locked wheels don’t slip anymore, they start skidding. Because the tire isn’t spinning, braking is
    purely achieved by sliding friction between the runway surface and the rubber tire. This condition can lead to serious tire blow-outs which can then on the other hand lead to structural damage by hurled tire debris, sparks resulting in a possible fire or even a loss of control. To prevent this from happening, engineers came up with a system called the anti- skid system. It basically works just like your car´s ABS, the Antilock Braking System ...
    Thank you very much for your time! I hope you enjoy this video!
    Wishing you all the best!

      Cool Content, Keep the Grind Up!👑

    2. Matthew Groff

      The Brakes used in commercial Aircraft are comprised of Carbon Ceramics, the same ones used in Modern racing cars such as F1, NASCAR, INDY Car, etc. The Technology originated from the aerospace and rail industries then to auto racing and now down to commercially available automobiles.

    3. Eric Lees

      That was very informative and educational thank you CJ

    4. yco67

      engineers basically invented ASS..


      Although I am a graduate of aeronautical engineering I am learning a lot more just watching Captain Joe's channel. Congratulations and thank you Captain Joe !

    6. Emil Heise

      Anti-Lock brakes were invented FOR planes! Jensen FF had a mechanical system, adapted from an aeroplane setup. In 1966 :-)


      Thanks for additional info

      captain joe are the keyring is abailable in pilipines?

    11. ilovetotri23

      You are so awesome! I never thought a video about ANTI-SKID, would lead to a reference about the AirTransat landing in the Azores! Glider pilot yes! Hero, still in question.

    12. Dirk van den Berg

      Dear @captainjoe, when a plan like that has burnt out its tyres, how is that plane removed from the runway? How many cranes are used?

    13. bruh hei hei boi

      Imagine the energy wasted was saed for poor people world will be yo this business

    14. Mohan Krishna Reddy

      If there is lot of Kinetic energy while touch down on runway, how much percentage that wheel brakes contribute to brake the speed?

    15. Yerdana Maulenbay

      Dislike from Seb Vettel fan) just kidding, they are both legends of the decade!

    16. Orbital Potato

      Electromagnetic brakes? The faster the wheels spin, the stronger the braking is.

    17. MVPever

      I like the fact that Joe explained that braking incorporates slippage. Usually in high school they just tell you that static friction is greater than sliding friction and that, since the instantaneous speed of a rolling wheel relative to the ground is zero in the contact point, ABS will keep the wheels spinning so that they can transmit the maximum amount of power to the ground. Whereas, using more than one reliable source I've found out that the peak of the coefficient of friction happens when there is a certain amount of slippage. Surely the motion of the tyre in that condition will be closer to a rolling tyre than to a sliding one, but still it will be sliding; actually, when the slippage is zero, so will be the friction coefficient.

    20. Wilson Phatrose

      Good morning sir 🙏 Is it possible to stop the aircraft without moving while it is flying above?


      I loved your thoroughness in explanation.... it’s a pleasure to learn something more, always and all ways.... Thank you for sharing

    22. Brandon Rozario

      what plane is that at 6:52 ?

    24. Tom F

      Long story short, yes, coded in RBCU are functions designed to report max & min speeds for each wheels. At least on the A350.

      Captain Joe so tell me, what level of education does one require to become a pilot

      1. my name

        A commercial pilot or recreational flying pilot?

    30. raptorclans

      I couldn’t stop laughing at the car going at 4,300km/h 😂 Nice work as always Captain

    31. Pratap Singh

      Captain Joe would you tell about existence of any automatic system in the aircraft which can be activated for commencing a go around necessiated due to some emergency, after a TOUCH DOWN. Seen in various videos that pilots do such emergency take off manually and the chances of some critical omissions during such flash manoeuvre activities may lead to disasters. In such cases Auto system may take care of actions like release of brakes, raising of the engine thrust, re setting of flaps etc.

    32. Jyothi P

      Joe ..what happens to braking if there is water on runway ??

      1. Oscar Blue

        It is reduced.

    33. Eli Abdul

      The intro song fits to Our Captain, Nice and Cool!


      My comment will make obvious very quickly that I am neither a pilot nor an engineer. I envisioned a breaking assist system that would be embedded in the run way: a series of flaps that open up at a low angle (held by modified air shocks) as the tires role over the flaps, they force them to lay flat again (that would compress the air inside of the pistons holding them in the raised position. that compressed air could generate electricity as it is being released) the kinetic energy of the plane would be transferred to the air pistons of the runway flaps in the form of increased pressure. The flaps that start at the point where the plan stopped and end at the end of the runway would be laid down flat again by releasing the air from the pistons through a bypass valve (it could be the same one that is used as an inlet when the pistons are being filled to raise the flaps in preparation to an incoming landing plane).

    35. Big Dog Outdoors

      Leave Hamilton out of it. He’s a cheater and a jerk.

    36. Cyrus gatpandan

      It’s scary

    37. Dyno

      But in what case would you want to deactivate the anti skid?

      1. ZK-APA

        Dyno if it's malfunctioning

    38. Davide Siclari

      And nowadays some abs make the wheel spin backwards for short moments

    39. Norbert koltai

      Heyy I have a question. When I'm playing games, where we can fly with planes, I just get stuck with this question: Why are the landing gears retrack with an offset? Is there is any problems that will happen with a not offsetted landing gear retracting or it's just designed this way?

    40. Dirk van den Berg

      Dear Captain Joe, how was that plane with the blownout tyres maintained? How do you get such an plane of the runway, and how were the tyres replaced? It is not like you can lift plane of that size like you can do with a car in a garage.

    41. Vicenc Vallverdú

      KE=0.5mv^2. M=340000kg,V=277km/h Therfore 170000kg×76729km/h we get 13043930000joules, 13 times more than you said. Maybie I'm wrong lol

    42. GreenCountryM C

      To put that 1.1 billion joules into further perspective. In healthcare, we typically defibrillate patients in cardiac arrest at 200 to 360 joules.

    43. Prakash Ambastha

      Hello captain Joe..Do planes have gears like we have in a car? or is it flaps which work like gear?

    44. BOXER

      I know all about airplanes

    45. Sudish Kumar

      Hey joe., i have question. As you said during emergency landing when engine fails / or fuel leackage situations., efficient braking with the help hydraulics and reverse thrust ans cannot be possible. So maual braking is the only way. Why hydraulics is not functional..? Is the power by batteries inside not enough to source braking power..? Or not allowed to burden batteries.

    46. priyanka raman

      Can you tell us the requirements of becoming an Air Force pilot

    47. Russia BLOLIUM

      Joe have you flown to Dublin airport before??

    52. Silver Spy

      Can you fly the new Flyingsim would be so great!

    53. Evani Cornelisse

      Maby do a vlog day where you vlog you're workday

    54. cath elena

      It would be good if you make a video on Microsoft flight simulator 2020

    55. AnaKary Aranda

      I admire what you do !!! WOW !! 😍 😍 😍

    56. Gaming BrosBogdan

      I have a question. Why do pilots put the gear down so early when landing?

      1. Oscar Blue

        The gear typically comes down on about a 5 mile final. Each airline has a “Stabilized Approach” policy that dictates when certain configurations must be met. Also, if the aircraft is faster than desired and descending, it can be difficult to slow down to the maximum flap speed for the next flap setting. The landing gear is one of the best drag devices on the aircraft, and can be used to slow the jet down quickly to the desired speed.

      2. ZK-APA

        Gaming BrosBogdan because the aircraft has to be fully configured and stabilized before a certain point during landing.

    57. Cristian Carvajal

      Make a flight simulator 2020 review demo please!!!

    58. Mustafa Osarwala

      Why PA systems are so bad in planes?

    59. S Q

      I'm just wondering, why isn't caption available in recent Captain joe videos?

      1. INFONITY

        S Q yeah! Exactly

    60. Ben Roman

      Joe 🤯 do a video about how accurate the new simulator is😱 I'm getting pretty good 🥳🥳could I fly a plane??


      hey Joe see my first smoothest landing in a simulator.

      Why Boeing 777X windows are placed higher in the fuselage? This is Glenn from Dubai and I am 9 years old

    63. Ashokan R

      Hi captain can you upload a video about runway lighting system. Thank you

    64. Daniel Holliday

      Just noticed this guys a first officer not a captain

    65. arrowghost

      Captain Joe, do you have any reaction or plan to play Microsoft Flight Simulator 2020?

      1. ZK-APA

        arrowghost yup he does (source: his insta)

    66. Your Local Space Marine

      Could you play the new flight simulator FS2020? Test the accuracy of the simulator, that'd be cool.

    67. Louis Milone

      You know the outro song is what convinced me to become a pilot when I grow up 8:45

    68. Girish pai

      Captain Joe what do you think about AirAsia safety violation on only flap3 landing and violating sick leave rules in India where one capt had told the truth about the company and what do you think about this situation he is a youtuber just like you with 3 million subscribers At Flyingbeast channel when he had revealed the dirty secrets of AirAsiaindia.

    69. abduswamad alwy

      1 month,no video ❗❗❓❓⁉️⁉️⁉️

      1. INFONITY

        I dunno

    70. CY GAMERS

      this comment will make u quit ur pilot job do u remember flight 9/11 >:) >:) if u dont know seach "flight 911" i wish u and other pilots see tis coment

      1. Oscar Blue

        I suspect this is going to be the most ludicrous comment when you explain why. Nothing showed up under Flight 911. So, you are going to have to elaborate.

    71. Stephen Hinkle

      Can you do a video on how airlines plan out which flight will go out of which gate number? When I go to the airport, it seems pretty random, although I doubt it is actually random. What factors actually go into how the airlines assign the gate of each flight? Does it matter the type of plane? Flight Time? Proximity to other aircraft? Number of expected passengers? Grouping of common connections? Do different airlines use different gates? I am curious how this process is planned out.

      1. ZK-APA

        Stephen Hinkle the gates are usually randomized. But there are factors which determine the randomness. Eg some gates can handle only certain kinds of aircraft (some are for narrow bodies, some for wide bodies, and some for say the A380) And for gate from an aerobridge vs gate to a bus to go to the aircraft, the latter is usually cheaper, so some airlines prefer that. But mainly gates are assigned to maintain maximum efficiency.

      Joe, My name is Joseph. I am a senior in high school, and I am committed to becoming an airline pilot. I am hopefully pursuing this at Purdue University. Do you have tips on what classes I should signed up for my first year in college or what classes I should try and take? Thanks

    75. xp xp

      Captain Joe, suggest to compare the cockpit of A320 vs A220

    76. Aviator

      Do planes also have ESC like a car? To prevent sideways sliding?

    77. Danneko

      I have a question: is there any possible way to get taken on a plane by a pilot? Like a bus driver could say "hes with me" so no ticket is needed?

      1. Tropospheric Aviation

        Only private aircraft, you need to limit it to 1 passenger though

    78. Raj Aryan Ranka

      play microsoft flight simulator

    79. PrinceLevelUp

      Please play the new Microsoft flight simulator on video

    80. Eugene Krabs

      Joe, since 9/11 airport security has been increased a lot, cockpit doors have changed etc. But you never hear about pilots and how they make sure that there are no hijacking and all that.

      1. ZK-APA

        Eugene Krabs there are some things done to counteract that Some are publicly known concepts (eg sky Marshalls). Others are within the company and are not discussed for obvious reasons.

    81. Arlandas Medževepris

      Captain Joe! Play new flight simulator 2020!

    84. Malcolm McFadden

      Love your videos Captain Joe! i learned a lot from you! keep up the great work and stay safe out there please.

    85. Miroslav Marinov

      Is there a determined point after which you shouldn't land or the runway will not be enough? How do you determine this. I guess it depends on the type of plane and length of the airstrip.

      1. ZK-APA

        Miroslav Marinov usually if you can't touch down in the touchdown zone (marked on the runway with white bars), you go around. But yes ultimately it is a PIC call to continue or to abort

      Captain Joe, Please make a video on Flap 3 and Flap 4 Landing...

      1. ZK-APA

        thekpdon10 there isn't much to it Flap 3 (or a lower flap setting) landing gives better fuel savings and better go around performance Flap full (or a higher flap setting) landing gives better landing performance

    94. ammm zeee

      Where is new video Joe?

        No he still is a FO. He said he won't be a captain until 10 years or something like that.

    98. keelan James

      Am I right believing your a senior first officer not a captain?

      1. spade

        yes he is a senior first officer

    99. Jose Bemila

      Captain Joe, I need calrification on one scenario..please clarify it. The scenario is in an airport where planes lands for every 3 seconds continuosly back to back, and suppose if a plane which is landing having some defect or landing with instant emergency (unpredictable) and stopping in the main taxi way, then what procedure would be followed for planes which are coming behind of this to avoid collision? Is there any alternative preplanned procedure in aviation field, since they allowed these many planes to land for every 3 seconds? Please make a video about it.. I am having this question for long time..

    100. Olle Hultman

      Why doesn't the wheels come with electrical engines to speed them up prior to touch down. Wouldn't this prolong tyre wear?

      1. Marc McReynolds

        One of my jobs in an aircraft landing gear group used to be replying to letters from people who had invented pre-rotation of tires (I was given the task after arriving in the group from college with this great idea for... pre-rotation of tires!). The bottom line is that all the smoke and noise doesn't amount to much wear-wise, so given the various weight penalties and potential operational problems which would go with any sort of system (there are numerous ideas put forth for how to do it), pre-rotation doesn't come anywhere close to being worth it.

      2. ZK-APA

        Olle Hultman not really. Especially considering that adding motors will increase complexity, weight and costs. So even if there was a gain, it'll get offset
