I dare say it was completely believable for the people sitting 230 feet back from the cockpit who were thrown about like rag dolls if that video is at actual speed.
I get that the surface area of an A380 will require additional rudder input that my lowly Q400 does not, but a little care for passenger comfort and attempting to find a better method for dealing with crosswinds and gusts goes a long way. Most passengers don't mind a little more roll than normal, but boy do you hear from them if you give them any sense of feeling in yaw.

Anyway, we see the effects of late-phase rudder inputs feeding back into the oscillation instead of damping it. Left swerve, corrected by right rudder. But it also self-corrects to the right due to the natural directional stability, and the pilot maintains the right rudder too long. So both those effects combine into a right swerve. So the pilot puts in left rudder but maintains it too long, etc.

On finals it looks a little like pilot induced dutch roll. The aileron & rudder inputs were not too coordinated. The lack of finesse with rudder was further demo'd during the flair. I've not flown FBW or side-sticks. From those with hands on knowledge is this common or difficult in your early days? Having said that would EK put AB newbies directly onto A380? Surely not. OTOH we all have bad days occasionally.

That should be today's EK55 to Düsseldorf, arriving 11:31z on runway 23L, with a variable 20G32kt crosswind.

What is the 380 crosswind limit? 40knt? In any case seemed pretty much on the edge of reasonable flight envelope. I hope cabin crew at the rear did fasten their harness...

One thing to remember on FBW is that the control surfaces are doing their own thing trying to keep the airframe in it's last commanded position. Hence what you see may not be pilot actions. PIO is often the result of over controlling & not letting the gizmos do their job. The human is often correcting just as the gizmo corrects so over control results. Not sure of the logic blend on the 380. But once on the ground things tend to get conventional with some surprises. e.g. A320 halving the aileron deflection on touch down. My experience is A320/1 & A330.

Interesting that they allowed another plane to take off from that runway immediately after, I would have inspected the runway for FOD before...
Good job, Messier Dowty and Goodrich
Probably the FAs had to clean up the rear galleys after that "landing"

Really? Is that an A380 procedure? A 737 is a real handful without yaw damper in conditions like those in the video.
I must be a bad pilot. I hardly use any rudder during approach, only just before touchdown. The guys in the video were properly shocked. Spoilers and flaps left extended when leaving the runway.
Probably two seats now available on the A380 in EK.

Lot of people on here know little or nothing about modern FCS and the 380 in particular. The aircraft is very stable and needs no rudder on approach (although the system may put some in but not as radically and rapidly as the video). Turning off yaw dampers? Welcome to the 1970s. Not even possible.
Standard stuff. Get it on the centreline, at the appropriate height select the landing attitude and smoothly kick off the drift. No adverse roll to worry about.

Usually 777 FO to A380.
