Not to discredit your point, but a) those wings do support the plane while it's flying, so really as long as the two wing jacks are solidly connected through to the wing spar (main structural member of the wing), it's not that big of a deal. Also b) Planes are surprisingly light given their size (kinda like scaled-up empty coke cans), they're designed that way. So yes, it weighs 277 tonnes, but that's just 5 big semi trailer trucks or one tenth of a Virginia-class submarine.
As a retired aircraft mechanic, w/ 44 years, yes I can. The comparative size of the jacks are amazing. They seem smaller than they should be. I worked on large helicopters (H-53) for many years, the jack pads are and are attached to major structure. Also the structural size of the doors seems to be a bit light seeing as they stick out in the relative wind when actuating.
First retraction: 2:00. First extension: 3:00. Second retraction: 3:50. That's it. You may be tempted to keep watching to see the nose gear retract, but it's not going to happen. ;-) Fascinating video nonetheless.
I don't know what it is, but I watch all these "airplane gear retraction test" videos on RUclips. Something satisfying about them. What is wrong with me?
Mxolisi Bonga it’s an a380 because the gears mounted on the main body are six wheeled bogies while the 747 and a340 are 4 wheelers bogies Edit: spelling
Those jack stands look MIGHTY "petite" in comparison to the aircraft. Their tubes aren't even CLOSE to the landing-gear struts' diameter. Lots of confidence the mechanics have in their engineers...
Man by my impressions I say that's an A380 Singapore airlines. I don't know either what's more impressive, I think it's the Jack's holding that massive plane and talk about the tons required to lift that heavy bird.
It surprises me that there are 20 mains and only 2 nose. Im also impressed with the speed the mains come up in relationship to the speed they go down it would require massive hydraulic reservoirs and pumps to accommodate such forces. In addition to the drag exerted on takeoff.
*can we all just take a moment to thank the men and women who made the jack stands and jacks to hold up this A380 so that the crew can be assured that the thing won't fall suddenly and possibly kill them.*
Remember the jack points or lift rings on the top are not randomly positioned on the wing-skin. They will be at the strongest part of the wing structure or wing-box. An intersection of several structural members (ribs/spars) and in this case the same structure they keeps the engines attached. Same with your car. You can only safely lift it where the body sections are doubled up in the same place (split frame). If you tried to lift your car from the floor pans the jack would bend them in.
To add a bit more to the good explanation above me, these jack locations were designed for this. The mechanics aren't just choosing what they believe is the strongest part of the wing; these attachment points were put there by the engineers for this exact purpose and they were designed to easily handle the weight.
Thanks to the power of 5000 psi hydraulic Extension / retraction of landing gears Mainly after major checks or after fault rectification First jacking the aircraft on 3 points as per AMM chapter 7 Then the test using AMM chapter 32 Ha ha To easy 🇩🇿🇩🇿🇩🇿🇩🇿🇩🇿🇩🇿🇩🇿🇩🇿
It's awe-inspiring the first few times you do it or see something as big and complex as gear retraction on a large plane, but after a while it just becomes the norm.
Someone who has the information, can you explain why all aircraft have the main doors that open and then close once the gear is out? I have seen emergency landings where the doors are all open, so if the plan is capable of landing with them out, why do they even need to go back up? I always thought that the big doors were too big for the ground and that was why they went back up after extension. Thanks in advance for the reply.
It's also because when the plane is landed, under him there is a lot of ground operation in act, so if the ground Clarence of the aircraft is not so hight they must leave enough space to move around for vehicles and operators.

For aerodynamic purposes, the doors create a lot of drag when they are hanging out, and increased drag increases fuel consumption. The reason for the door is to keep the belly of the plane smooth when the landing gear is extended, so if they don't go back up then there is no reason for them to be there in the first place. When you see emergency landings with the doors out, that means that the pilots couldn't extend the gear normally and had to extend the gear by gravity. The process of extending the gear through gravity also removes hydraulic fluid from the landing gear and the doors, so once you do the procedure you cannot retract the gear or the doors, and thus they are left hanging out.
This resembles operation of the Miata "PHRT" (retractable hard top) introduced in 2007. When did Airbus design the landing gear? (ie. Who stole from whom?)
Its water that's settled in the various corners and double-skin sections of the doors and panels, either from standing in the rain or when it's had a pre-service wash prior to going into the hangar. Aircraft usually have a wash down before scheduled servicing so it's clean to inspect and work on.
Much respect to the engineers who made the whole system work
Such a tremendous job the engineers had designing these landing gears!
Magnificent piece of engineering, designing and producing aircraft like the A380 is one of the more complex endeavors.
Puyu
disassembled already for secondary spare parts
verdade.
I don’t know what’s more impressive - the gear or the jacks!
that what i was thinking
The bicycle
I think jacks they r lifting the weight of gears and plane so yes
@@nabatsingbhoabul4055 that was my thought lol
The amount of parts it takes just to fold gear is nuts

Damn I didn't know the A380 could hover like this - makes you question why it needs landing gear at all
Might be a redundancy system.
@@orbitalpotato9940 oh yeah maybe
Lol. It's just because it's using separate hydraulic jacks to lift the plane.
This A380 is broken thats why is hovering.
They brought it in to the hanger to figure out why.
So that plane is suspended by only 3 jacks!?!?! Can you imagine the structure, the reinforcement for those 3 points to suspend the plane. Man...
Well, it slams into the ground on 5 points- 6 if it’s a boy A380.

You're an aviator
You know what?
*S A M E*
How's damper operation (ie. Shock aborber) tested for leaks, "rebound" (bounce and jounce), heat dissipation, etc?
It's really amazing they got the plane to fly so slowly inside a building
It was pulled by a truck in there
@@neotastic5731 !? The truck was flying too??!
I respect you guys with your great work on technology...
Three jacks are supporting hundreds of millions of dollars or, equivalently, a few tons of pure gold. Impressive.
Thanks for recording the A380 gear footage.
Thanks I never wondered how landing gears of an aircraft works. The number of wheels on those gears tells that this is Airbus A380.
Could be 747 but with the shape it is a380
Sorry guys it's not an a380 , the shape of this planes wings to level, the a380 is more curved
Mxolisi Bonga it’s an a380 because the gears mounted on the main body are six wheeled bogies while the 747 and a340 are 4 wheelers bogies
Edit: spelling
Mxolisi Bonga also your statement bout the wings are irrelevant because you can barely see the wings in the camera view
It’s definitely an A 380 when you look at the shape of the wings and the engines .
I love that final locking of the outer rear gear...go engineers!
it is wing gear and body gear
That’s a damn beast!
I never knew watching landing gear go up and down was a thing.
Those jack stands look MIGHTY "petite" in comparison to the aircraft. Their tubes aren't even CLOSE to the landing-gear struts' diameter.
Lots of confidence the mechanics have in their engineers...
I'll take a wild guess and state those jack stands probably weren't sourced from Harbor Freight. The color is about right, though!
Big difference between static forces and dynamic forces, especially at leverage. Yes, we German engineers know our shit.

You don’t release how big these beasts actually are until you see them up close
Thai Airways A-380 the principal land gear in the wings is most similar to A330 land gear 1:16 registration HS-TUC
man Thai airways is beautiful
The bicycle has 24 inch wheels and tires. The aircraft is only VERY slightly taller, though wider, and there's more than one wheel on each bogie.
It surprises me that there are 20 mains and only 2 nose. Im also impressed with the speed the mains come up in relationship to the speed they go down it would require massive hydraulic reservoirs and pumps to accommodate such forces. In addition to the drag exerted on takeoff.
because A380 has a perfect balance of its center of gravity
Okay, to mention this is Thai Airways.
Very very nice!!!👍
That was some good. Tires 😆😇
Wonderful system, really great.
Beautiful design.
Beautiful precision parts.
The plane looks so small up close! Can't believe that plane holds 500 passengers!
すげぇ！

Wait.... guys who come to work on A380s, come on bikes??? Isn't that sweet! 🤣👍
Nice!
It just look satisfying while watching the video.

2:04 & 3:05 is what you are looking for
How tf did you know
those jacks attach to the A380 main chassis, tripods are marked A380 means it is exclusive lift for A380
Thanks for clearing that up. I assumed it meant they were only for Fords.
How these hydraulic jacks lift up this huge plane only applying force to a small part of the wings and how does it not dent inward????

When did Airbus design the landing gear? (ie. Who stole from whom?)
Just A Cover airbus basically stole the basic design for the landing gear from the 767 and the 777.
AIRBUS A380
With a a 4-6-6-4 set up it can only be one aircraft. A380!
Wrong- The correct answer is Cessna 177 Cardinal.
Better luck next time.

0:30 Now what's one hell of a tripod jack.
I have noticed in many of these videos, when the doors open up, there is water that spills from there. What is that all about?
I saw that also...maybe they give it a wash while its jacked up?
Its water that's settled in the various corners and double-skin sections of the doors and panels, either from standing in the rain or when it's had a pre-service wash prior to going into the hangar. Aircraft usually have a wash down before scheduled servicing so it's clean to inspect and work on.
