We have the same letter of beginning name. This is very interesting. I love your videos because they are so educational. My dream is to become a Pilot and am 12 and I am learning so much from you. Thank you. Congrats to people who found this comment :) 👨‍✈️ 🧑‍✈️ 👩‍✈️. ✈️✈️🛫🛬.

Hey Joe Please Open A Account On Twitter I Got Addicted To Instagram And I Was Not Able To Focused On My Goals

I don't think plane can take off from conveyor belt. Because according to bernoulli's principle Air air molecules need to flow around the wings to create lifting force. Even plane move fast enough on conveyor belt. Plane speed so slow relatively surrounded air. Because if plane move on run way plane go through the air molecules. But in this case plane engine suck surrounded air in to the engine and pushed from back. It create force to move plane forward but not lifting force on the wings. This is the way I think this question. Please tell me if I wrong.

Hmm, I always thought that with this one the plane could take off but the logic in the question means it just cant actually move initially, so its the semantics of the question but the bulk of actual the physics around the scenario means that it would take off it we substitute ground speed, got it now thanks. The conveyor wont actually let the plane move. I think a lot of folk get this right but for the wrong reason.

My beef with Ryan air is with the staff. I once saw a Ryanair pilot eating from a Tupperware in the cockpit. Felt sorry for him

If the aircraft had zero-friction & indestructible wheels it would takeoff normally as the conveyor belt has no means to product an opposite force on the aircraft. However, if you don't have the aforementioned wheels then the wheels would be destroyed on the takeoff attempt.

Hey Captain Joe, if you can contact Kennedy Steeve (Stephen Abraham), tell him he should write a book about his best moment as ATC ;)

Where is the captions

Yesss. Physics saved the day

No, the plane cannot takeoff if it was on a conveyor belt because it will snap the conveyor belt. If the conveyor belt got upgraded to handle more weight, it wouldn’t be able to have fast speed.

I need Corsair logo there

No, because not enough air to generate lift if depend solely on jet engine itself

What's the difference between the UK and England captain? Possibly explain how the other countries making up the UK were at no risk from a nuclear strike.

Actually the question as posed -- conveyor belt designed to match the speed of the wheels -- I think the answer is no. Yes there's thrust and the engines don't care about the wheels, but lets say the airplane starts to accelerate forward. The wheels spin faster so the conveyor belt is designed to spin faster with it keeping the plane still. No matter how much thrust the engines generate, if the conveyor is designed to match the speed of the wheels all the engines should be doing in effect is accelerating the wheels until they basically explode (or the conveyor belt does assuming it does what it's claimed to do per the original intent). The plane cannot take off without air flowing over the wings and that won't happen if the conveyor belt always matches the speed of the wheels.

Great vid, once again! Could your next video be about the different parts of the airport? (Ramp, Apron, Alleyway, etc.) Another one I'd like to see is the different parts of ATC. (Ground, Delivery, Approach, etc.)

It cant it needs air to generate lift if it doesn't generates enough lift it will stall in full stall aka the unrecoverable stall

this came up at work some 3 years ago i my answer has not changed. My answer is no it will not take off and the reason id the tyres will fail from overspeed before the plane has moved very far, the reason is as soon as you start to move the plane is say moving at 1m per second then the conveyor will match this but that will now make the wheels do 2m per second and so on in a runaway feedback loop till the tyres tear apart and then the plane is going nowhere

This whole issue could be solved by hiring more women pilots.

What if airplane landing with the conveyor belt?

Of course....the military is much different.......1 example....Vr is not used for Rotate in military flight ops. Vr = Refusal Speed.......Vrot = Rotate.

No it won't lol

Theoretically it MAY work, but, the problem is that for a plane to “run” in place until it “gets” to speed, there is not enough airflow on the wings to lift it. Practically speaking, it is impossible to build a conveyer belt of that size to move that fast while having enough support for the weight of the plane.....actually, if it is possible for the plane to build enough thrust, and the conveyer belt can suddenly accelerate, without delay, to the take off speed of the plane, then it will allow the plane to take off at much shorter distance....kind of like how jet fighter on aircraft carriers....but I feel sorry for anyone on board....

This is a movie effect being used during 1960s, like Thunderbirds (1964)

The thrust is moving the airplane - not the wheels. Therefore, the airplane will accelerate and take off.

I have more chance of winning the lottery then I do of becoming a pilot, just watched because I was curious about what a pilot takes given that they travel so much

Ultrasonic ping or ultrasound ping? Are these two same? Confused with other MNglobal vids! 🇮🇳

I imagine the first phone call between Mr. Kiker and Boeing was a bit fun. Mr. Kiker: we are gonna put shuttles on top your plane like a car luggage carrier. Boeing: (mutes call and look at each other) Nasa must of stopped doing drug tests.

You can test this this with most LCD TVs. take your polarised sun glasses and rotate them 90 degrees. TV goes dark

I think it will still take off because the whole point of long runways is to buy time for the plane to pick up speed and it will still do the same thing if the runway is 'spinning".

It wont take off. Trust me im an Aero Engineer

think of it this way, if you put a turbofan on the back of a car, making its wheel move on its own, would it takeoff?

If what he's saying is true then engineers should just focus on powerplant instead of focusing on the aerodynamics of an aircraft.

not enough airflow under the wings that generate lift, so this is impossible

Well, that's a nice unstressful procedure !

I rewatch this video occasionally just to watch Michelle being extremely sweet.. I know this sounds very superficial but she is just so charming I cant stop watching her..

the heroic stories of the falkland islands war and operation 'runway pothole' always brings tears to my eyes, tears of laughter

Engine failure @ 500ft coming in to Heathrow 27L !

Ok so here is my take on the whole thing. (I’m absolutely *not* confident about my answer XD) I think at the beginning, the engines spool up and the plane starts to move, so does the belt. The plane while behave like a car on a dyno (a test stand if you will). But I think, because the power is provided by the engine and not the wheels, at some point the thrust will be to great for the wheels to be kept on the belt and the plane will skip over the conveyor belt. But it will not take of as there is no air movement around the wings and therefore no lift.

No, it won't takeoff because there won't be any wind coming from the opposite direction that generates lift as the plane is at the same position

What is this guy running this on!

They actually did this on Mythbusters. Great episode. If it was a car. It wouldn't go anywhere. But it's not a car, it's a plane and the wheels have nothing to do with moving the plane. You'd need a wind tunnel instead to be your "conveyor". Then you could maybe stall the wings

No. It's air speed that lifts a plane, not relative wheel speed. It would scare me if someone thought it would.

did u talked german? 😊 i heard- wunderbar

God bless the professionals

I think the plane in the first example *might* still take off, if you take friction into account: If the conveyor belt has any friction at all, at some speed it would take enough air with it to "blow" onto the plane, increasing air speed, thus the wheels won't be needed anymore. If it didn't have friction (to avoid this scenario), the wheels wouldn't have any friction there either, so the plane could take off just sliding instead

What if the brakes were applied and the conveyor run in the opposite direction? What would this mean for ground speed vs airspeed? Would the airflow generate lift as normal, enabling take-off?

Sorry Joe, answer #1 is wrong. You would just have the wheels spinning at 2X airspeed. Wheel/ground speed & direction is irrelevant. You even state this directly at 6:55. Unless the trick answer is that friction overcomes thrust, but you would need far more than 2x speed on the belt.

, how they clean or valet inside aircraft?

hey, isn't the radios off...its not showing any frequencies

I don't like boeing, but those are nice planes

hey joe how did u generate those graphics of conveyer belt and B 747, what software do u use to edit your videos, please reply

These people are so lucky they had someone that could stay calm and handle the situation. The training these pilots receive is top notch as they always have so many lives in their hands. Great job pilots!

No Because the airplane don’t move

Hey Captain Joe, I would really appreciate a video on why you shouldn't be afraid of flying. I know a lot of data and sources already exist that prove that flying is safer than even walking up a flight of stairs, but some people can't fathom the idea that cruising at 35,000 feet above the ground is actually safer than walking up or down a flight of stairs and driving on the road. There are a lot of videos on MNglobal about this topic but someone of your image would be able to make a real impact in reassuring scared flyers.

It's so hard to listen to the physics explained by the rookie or for the rookies.

Who would even ask this idiotic question?

Im literally watching this for understanding xplane 11 mobile

What does the NTSB personnel do when they're not investigating on an accident? Would be interesting to know about their stories like if they're engineers and they are called out from their ordinary job to work for the emergency for a period of time.

no

Boeing deserves to fail, it's so wrong that everyone responsible got away with this. Never fly the MAX . Ever

Wasn’t this Something mythbusters did with a Cessna and a car with a super long blanket and they succeeded to take off

It will not take of

(1) I’m confused why your conclusion is that a passenger couldn’t do it despite the fact that your test subject did it; and (2) if it were me, I would much prefer the voice to speak clearly; I find this calming/soothing voice to be too mumbly, personally

I would rather take the bus

Thrust + airfoil of wing(airflow) = Lift. Take away the airflow because it’s stationary. I’d say it won’t create lift.

The wheels themselves in the first scenario would have to roll really really fast to produce an enormous amount of drag 🤣 the drag created from the wheels turning, would have to be equal to the thrust 😅

I can't believe this is even a question. It's like asking if a car will drive forward if the headlights are facing backwards. The wheels have nothing to do with what makes the plane accelerate or fly.

Joe you're overthinking it man. The wheels freewheel. They can spin backwards, forwards or not at all they don't affect the thrust acting against the air. The aircraft takes off either way what changes is the wheel rpm.

I just get started to watch it on 1:00. And the answer is definitely no. Aircraft need the lift and drag force to take off.

Beg to differ. If the conveyor belt works against the wheels the WHEELS would be standing still. That would mean the conveyor belt moves forward in the same direction as the thrust. Your graphic at 2:58 shows the conveyor belt to move in opposite direction. This won't stop the wheels, but instead make them turn at double speed. So with a Vr of 150knts the wheels would be turning 300knts. You may now a tire, but taking of is no problem. No need for infinite speed.

Next riddle: where do we get a conveyor belt that big and place a whole plane on top of it.

And now I know.

Ok so they're not calling the airplane fat? 🤔

Joe, if you need 10 minutes to explain lift to a non-expert audience, that's generous of you, but it's a waste of my time. This is very close to hucksterism. Let's see what you've won: A bright, shiny "do not recommend this channel" award.

OF COURSE! DIDN'T YOU KNOW FROM HS SCIENCE THAT IT'S THE ROTATION OF THE WHEELS, NOT THE WIND BENEATH THE WINGS THAT CAUSES FLIGHT!

The link to your little plane isn't working. I get a 404 error. BTW, is it available as a build-it-yourself model? 😃

This technology is actually already being used in secret russian aircraft carriers.

water does not compress, can only try to displace it in efficient way

No air speed . No lift...

Fantastic explanation in its entirety. Also, excellent calm composure of all involved is very crucial. For the safe landing and passengers safety, a big kudos to every one!
