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.
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.
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
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?
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...
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.
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.
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.
@@pimuce I would argue that a functional test is a static test whilst an operational test would be done in flight with aerodynamic forces on the gear. Discuss🤔
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.
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.
*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.*
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?)
I can see absolutely no reason for checking NORMAL gear retraction and extension. It gets checked, fully, every time the aircraft flies. I assume the A380, like all other aircraft with retractable landing gear, has an emergency extension. This is all that needs checking as it is never used in normal operations.
Depends on what they have been working on. They might have replaced all the landing gear on that maintenance visit, which would require a full swing using both the normal and emergency systems.

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.
You do not find the hydraulic jacks unsuitable because they are uncoordinated, the problem can be solved by making the jacks electronically controlled and then connecting them in wi-fi with a portable PC and with a software for height adjustments in relation to the specific chassis of the plane, but this it is expensive. Another matter is to use a giant bridge wagon with several hollow descents with the use of a double lifting system with suction cups on electromagnetic frames.
Magnificent piece of engineering, designing and producing aircraft like the A380 is one of the more complex endeavors.

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...

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.
Damn, what a gorgeous bird she is!
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

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.
those lifts are beasts
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????

those jacks attach to the A380 main chassis, tripods are marked A380 means it is exclusive lift for A380

Three jacks are supporting hundreds of millions of dollars or, equivalently, a few tons of pure gold. Impressive.
