Gear down, three green and let´s get started!
So let´s look at the different types of landing gears. The most common one out there is the single axle landing gear with a tyre fitted on each side mounted to a large strut. Mostly used on passenger jets such as the Boeing 737 and Airbus A320.
With increasing weight, you need more surface, so more tyres to evenly distribute the weight of the aircraft.
So if we look at the main landing gear of the Boeing 757, you have the main landing gear strut, which by the way is filled with nitrogen acting as a spring force and hydraulic fluids for dampening. Then you have the truck or boogie, and four tires in tandem pairs. But more importantly, for today´s topic, you see this little hydraulic actuator right here, the so-called truck positioning actuator aka the tilt actuator. This little actuator is attached aft of the main gear strut and pushes the rear wheels downwards forcing the forward wheels to move upwards as the truck is axially mounted to the main strut.
As the plane comes in for landing, the rear wheels touch-down first. The actuator holds up against the pushing force, otherwise, the rear tires could bounce up, slamming the forward tires into the ground. Once the weight of the plane presses the tires onto ground, a pressure relief valve opens up and the actuator collapses letting both tires touch down. This all happens in the split of a second. Once the actuator is fully compressed, so weight on wheels, it triggers the air/ground sensing unit from air to ground before the nose wheel has touched down, automatically extending the ground spoilers and allowing thrust reverser deployment and depressurizing the aircraft etc.
But see more in the video
Thanks for watching, all the best your "Captain" Joe

I’ve been an aircraft maintenance professional for 20+ years, and I can tell you that very few pilots have this much knowledge about aircraft systems. Troubleshooting discrepancies would be much simpler if all pilots were this well informed. I’m very impressed.
So nice to say that really nice
I agree. The number of times that I've ran in to a pilot that had any idea that planes don't fly with dragon and unicorn power makes this incredible to listen to. I'm impressed. It is fun to tell them that the discombobulator in the flux capacitor is the culprit. Especially when they say something about that being their first thought too...hardest part is keeping your face straight...
lumpheadthump same here. 12 years AMT. this is one of the few pilots we might not be able to bullshit. Hahaha. Surprised he actually knows so much on the mechanical side.
I'm going to keep this in mind as an aspiring pilot who's yet to start for his PPL/VFR rating.
Really?? I thought they're supposed to know😱

As a retired airline pilot, I am amazed, despite their complexity, how durable and reliable the landing gear are. Respect to the engineering and maintenance that went into the sequencing of the gear doors.
you must be lucky to lived ur life as a pilot. was this your dream?
@@kingofaviation Not luck, dedication to studies.
@@theminecraftpig661 can I became pilot
That was awesome. After spending 28 years as an electro-environmental tech, I loved it. Pilots are not required to know the details. If it didn’t operate properly, they have a checklist, can they continue, abort or IFE. As a private pilot student, it gives me more confidence knowing how things work. It’s an advantage as long as it doesn’t make you a cocky pilot.

Yeah he gave us a clue, by showing her shoes and then videos of a landing gear going in and out. Joe's landing gear went in and out a lot that night.
What were you guys doing together when she forgot her heels ;-)

😂 and 69 likes this is great
And making sure she could rotate 😁
Yaaas! Finally someone explains what gear tilt is
LittleSophia _ I would think it was pretty obvious why they tilt.
halcyondaystunes surely it's not just the fitment of the gear into the wheel well? That doesn't explain why the 777's gears tilt AFTER it is lowered. I've always thought it's to smooth out the touchdown so that not a large amount of wheels are contacting the ground at the same time, which leads to a higher shock to the fuselage.
@@LegitMoose THANK YOU !
i think it is tilted so pilots can butter
gg
When you have tilted gear it’s an automatic butter
Th3DevelsLettuce a very smooth landing

what are you talking about? why do you have to be a pervert? we were talking about planes and heels you pervert
Pervs! Lol
As I'm on the way to become an aircraft mechanic, I say that such knowledgeable information is highly valuable to me. It's even better than that of the booklets we're given by the aviation school!
You and Dutch Pilot Girl are hooking up. Do not deny it.
In the 50 most asked questions to pilots by people video, Joe admitted that he was still dating a passenger he met.

Well if they werent screwing around then why was the heel there? she just couldnt have forgot it cause nobody walks home without their shoes on....
Being a pilot is so fascinating and I've always been in love with it...
Ich verfolge deine Videos schon lange aber ich muss nun einfach mal was loswerden:
Deine Videos sind von der Qualität und vom Content her einfach auf einem solch hohen Level... Das ist einfach unglaublich :) ich kenne keinen TH-camr der auch nur ansatzweise einen solch hochwertigen Content produzieren kann wie du :)
benedikt170 dann musst du dir mal PhysicsGirl, Mailab und so anschauen... Ist auch sehr hochwertiger Inhalt.
I live literally right next to the Dover air Force Base. I get to see c-5's and c-17's take off all day. It's something to see the landing gear turn and go up and watch something that big fly
Aside from issues of storage space, the biggest reason for the landing gears to be tilted is to prevent excessive lateral force on the landing struts from having all of the tires dragging against the ground at the same instant. That lateral force won't break the struts, because they're designed strong enough to stop the plane using the wheel brakes alone, but the lateral force CAN create vibrations in the landing gear system that could damage parts throughout the plane after a few hundred load cycles. The belly gear supports the entire weight of the belly during the first instant of touchdown, so there is less time for the belly gear to start vibrating upon contact with the ground, and it isn't necessary for the belly gear wheels to be tilted as much to prevent those vibrations from occurring. The wings, on the other hand, still support their own weight by generating lift during the first instant of touchdown, so the wing gear has more time to generate potentially harmful vibrations as the wheels contact the ground, so spacing-out the contact time by tilting the wing gear wheels more is beneficial. If it were the other way around, then the belly gear and wing gear would be arranged differently to provide the necessary tilt for each.
shawn.
An eagle lands with its feet pointed upwards - do they have struts?
Frobe.
You say something relevant then; why do eagles have their feet pointed upwards when they land?
Fraud.
It took you a while to think that one up; that is not the reason anyway, eagles have their feet pointed upwards to create drag and slow down in order to make a soft landing.
As a mountain biker, I've crashed and gone over my handlebars a few times, which is a bit like an eagle landing ;) , so I believe I can provide an expert answer to this question:
Eagles land with their feet tilted up so they don't accidentally drag their knuckles on the ground and scrape off the skin. Also it would be hard to grab a tree branch while gliding forward if their feet were tilted down and their talons were pointed rearward. The comparison to Boeing jets would be valid, except that eagles don't have wheels on their feet, so it's actually a completely different scenario. And yes, eagles do have struts -- the muscles in their legs provide the same shock-absorption on touchdown that struts do on airplanes.
@dwarfedgiant: There is no mechanical difference between grabbing prey vs. grabbing a branch. Their feet are still angled up in the moments before contact.

Underrated
The way you were holding the high heels reminded me of Cinderella 😉😂...congrats on 600k!
so you picked
I'm glad you mentioned the C5. The first time I saw one up close at an airshow, when I was 15, I couldn't figure out how it fit in the wheel wells.
You explain everything so smoothly. Thank you a lot 🙏. I want to become a pilot too. God bless 😇
Hope you have a good future in flying a A380 😉👍
Techniques For Everything Thank you 🙏
Suzana S the world is currently in dire need of new pilots
7:07 man your screwed if those wheels don't turn
Something like that happened to a JetBlue A320 back in 2005.

You’re
jcwat well that’s why you trust the discipline of the military haha
JetBlue
then just hope for strong sidewind or do a quick handbrake turn sideways just before touchdown and let her slide in...
Even though it's not their reason for being tilted, being tilted makes landing gears 10 times more beautiful. Especially my ex-love: 777.
Why ex-love? I just didn't see one for a long time. I will probably fall in love again when I hear those GE90's and Trent 700's.
you mean shoeless
Trent 800. 700 is A330ceo
Ge9x
Finally, Spanish subtitles to understand the content of the videos. It was time. Thank you
The episode is 7:47 long. Coincidence?
I think not.
Yeah lol
How about Antonov's landing gear? It looks interesting...
there s just a lot of wheels
What is so special about Antonov An-26?
Great vid. Only a small correction..the oil in the strut is for damping not dampening
for tack control it's easier to stabilize an aircraft to a surface when you have some form of lateral force trying to push your plane to the side ect.. like a car that's air born can it steer in the air no. a plane can yes but on landing not so easy... Plus if all wheals hit at once the forces of the inertia to turn to wheels up to speed upon hitting the tarmack may damage the landing gear. So it's easier to do one at time.
Never thought about it. :) Thanks for the insights, Joe! Excellent vid. Always delighted when I see a new one is up, for they're not only informative but it also puts me in a good mood to listen to and follow your explanations. Happy landings, captain!
Andy Kashu thanks Andy, such comments are my driving force!
Captain Joe and Dutch pilot girl makes a very good pair..airbus Vs Boeing, opposites attract 😍
Yes, but Joe flies 747s now for Cargolux.
Diegothepianokid03 oh thanks for updating me.
Boeing All the way !!!!!
Lowkey thought it was to make the landings smoother.
Eric 6645 I can see it being an added benefit or at the very least, a happy accident.
I mean airbus 330 is a *B O A T E R* machine so i get why u say it
butter landing
@@RealHudsonRailfanner you came from swiss001
i am not even a pilot, i just love learning about this stuff. great videos, keep em coming!
6:46 the German 3 hand signal. Inglorious Basterds taught me something after all.
megaman5125 yoooooo! for real 😂😂
hows that german? how would you signal 3?
In the USA, you use the middle finger, ring finger and index finger.
@megaman5125-haha...just watched the movie on SHOWTIME!
It's not really German, it's most of the world. Outside of the US, the UK, and a few other oddballs such as Japan and India, most of the world does what you call the "German" way, which, again, isn't specific to Germany nor originates there.
When I saw the thumbnail I was like "We're going in tilted boys!!!!"
Good Job Sir, you're one of those few Pilots who really understand the aircraft systems. Salute to you Capt. Joe 🛬
Yes. Hats off to ground crew maintenance mechanics ! Gear up/down can seem so graceful, almost like a dance. Mirroring how a bird would extend and retract feet.
We understand Joe, Dutch is pretty fit like
Thank you so much, this is such a learning experience for me. I am currently building a model 777, and was curious on its running gear, it's like my favorite. You've helped me understand it much more 🤗
Hell yeah! C-5 got mentioned!

Hello, I'm a fan from Thailand who really likes Captain Joe.
This video is 7:47 min long.. Nice. ❤
The Boeing 747 has tilted gear, so perfect coincidence.

Im airline pilot for more than 10 y and i had no idea about it! Thank you capt Joe. Enjoying my paid leave to improve my knowledge! Cheers
Great video Capt.Joe. Would have loved to see the B-52 gears in operation, especially with a stiff crosswind.
6:13 anybody else notice the mirrored Air France logo and registration?
Flipped for continuity of landing direction of all shown aircraft?
ECNARFRIA
Love your videos
Canadian Plane Spotter me
Joe Sterling is that basically a fancy way of saying the video was inverted in a way, meaning instead of the plane landing heading right the true video would be the plane landing facing left?
I watch those C5 Galaxies all the time flying through my town. That sound that comes from those engines is incredible. Very impressive planes.
It is awesome how you incorporate actual footage (no pun intended) into your videos. It is awesome to see these engineering marvels operate.
Joe gave us a clue by showing Dutch girls shoes and showing how a landing gear goes in and out that's why he kept laughing Everytime he picked up her shoe because he kept remembering the night Dutch pilot girl spend the night at his house. I bet that night Joe's landing gear went in and out a lot. 😂
I just hope that in the next video you won't show us Mentor pilot's shoes. 😂😂😂😂😂
Cody K. That's why the bed was shaking
Come on. Don’t embarrass him
Aviation Nut yeah something went on that night
Cody K.
I am just worried that in the next episode he might show us the shoes that mentor pilot left.😂😂😂😂
Aviation Nut mentor pilot is going to be the best-man...
Simple when you think about it, but then I had never thought about it. As long as they go up and down and lock when they are supposed to I am happy. But very interesting all the same Joe.
I think you meant to say you both had a great night inside. Not out. Lol ;)

Awesome video Joe.
I really like the idea of being a pilot and having a You Tube channel at the same time.
I like the way you snuck in your love for your aircraft - the video time was 7:47 😀
Nice Socks Dude👍
Joe, thanks for all the great , you’re my mentor when it comes to aviation ❤️
What about Mentour Pilot? (You see what i did there :)
Mentour Pilot also make really nice videos
My gosh thanks for sharing actually amazing facts! I never even wondered why there is gear tilt it just looks stunning😂
I wish you had shown the C17 landing gear and the B52 landing gear as well. Both are very unique designs. The B52 however is truly a one of a kind, being that the gear can all be steered in such a way as to allow the aircraft to takeoff and land in extreme crosswind conditions with the aircraft actually traveling down the runway at extreme angles. I hope you will consider doing a second video featuring these two unique landing gear designs. As always, love the videos.👍
hey Dutch people out there! i have made a Dutch translation, enjoy! hey Nederlanders! ik heb een Nederlandse vertaling gemaakt, geniet ervan!
Because the Dutch don't speak English, especially those who are interested in aviation, right?
And it's not like there are Dutch subtitles right?
dXb lol
dose that mean she is hot
I was wondering what pilots do when there landing gears fail to extend. Can you please make a video on this topic
Saahil Mehta They land without them
Ooooh that's a great suggestion for a video, Saahil Mehta! It's called a "belly landing," (among other names). Pilots actually get training and practice for the procedure. If the procedure is done correctly, pilots can land the plane safely without injuries or maybe just a few minor bumps and bruises at the most. The plane itself however.... is a different story entirely.
they land upside down
They take a viagra.
Saahil Mehta they do a belly land which means that the engines would be their landing gear
Boogie is Bogie beam. One is a dance one is a gear part..
Isn’t “bogie” pronounced with a long “O”?
I just hope I’m not the only one who noticed the video is 7:47.
This just kinda makes me happy 😁
Hi captain Joe, your logo looks like Monza Race track :)
no, curva grande is a right turn, not a left turn
Nice socks you got there
Do pilots press all the buttons in the cockpit in a flight(4-5 hours) long?
Harsh1K20 Hopefully not. I'm sure there's some kind of fire extinguisher button...
Nope some buttons are for heating...some are for fire extinguisher (it will shut the engines off)

Glad to see you use the dance step hill/toe, tie/hill analogy to demonstrate the landing gear of an aeroplane.
Great video Joe! I surely learned something today! Thanks!
True
Kannst du die neue Beluga XL analysieren?
Space isn’t he only reason why landing gears are tilted !!! Engineers understand that bracing landing on a step by step process ie each tire hitting the ground one after another smoothens landing and makes it for a smoother ride Bc it isn’t hitting all in one shot but bracing its fall slowly like a cat or a human you land on your toes and bring your self down to plant your feet Bc it makes it easier on your legs to take the weight so you don’t hurt your knees
heel and wheel not the bad idea.Thanks Joe. I like your example, first we touch our heel then toe to walk same as the aircraft.
_I am just wandering, is all this your own research, or is someone organizing /preparing this for you... I really dig your videos by the way... good job man_
Great video Joe! Notification squad!
#Team
That was the most surprisingly amazing thing I've seen in a very long time. One of those things you didn't realize you wondered about until someone explains it to you. Thank you!
If anyone remembers the Handley-Page Victor, the main bogie completely inverts before the gear stows into the wing on retraction.
It's effected by tip-hooks on arms that pull the front of the bogie upwards as the retraction-jack retracts and folds the leg so it fits into the thickness of the wing. The wheel diameter is just a couple of inches smaller than the thickness of the wing.
Sadly, I don't think a video exists of this amazing mechanical feat in action, but it was so brilliant that there used to be a full-size working one in the Science Museum in London many years ago. I remember seeing it as a child in the 60's. Little did I realise I would actually work on that equipment some years later!
"Unless you do a moonwalk..." Subscribed. ;-)
Congratulations on 3/5ths of a million subscribers! *Only 2/5ths left.*
Awesome video!!! I had this question for a lot of time!
Cap'n J, you've just answered a question I've had in my mind for a lonnnnng time. I always thought that even forces need to be placed on the gear as it touched the ground, but that quite evidently is not the case; it's about space planning and, well, the laws of physics and adroitly managing mass. Brilliant video. Thank you.
plot twist: he's speaking about his own high heels experiences :D
As I've been enjoying your informative videos, I've been wondering how those little toothpicks of a landing gear can handle all of that weight and those forces (lateral forces especially) without snapping.
Landing gear struts are not "toothpicks." If you look at them up close, you will see that they are massive pieces of heavy engineering.
Background music same as in The slow mo guys vids
when the pilot love his job thank you very much for this information
