I don’t believe those rudder inputs on approach are pilot inputted? Can an A380 pilot confirm this? Isn’t it the Airbus attempting to remove the sideslip by correcting itself?
Not flown the 380, but on other bus types it certainly does not attempt to remove drift before landing. I'd bet the house that neither does the 380.
Almost certainly inappropriate pilot rudder inputs prior to landing.
Perhaps a bit more time in the sim required.
