I had the privilege of being SLF taking-off in an A380 on an exceptionally gusty / X-wind day in Toulouse and watching the extraordinary movements of the ailerons. Never really seen anything like it - surfaces moving very rapidly up to about half-travel and in opposition to each other. But a remarkably steady ride.
(How gusty?
Here's a cockpit movie of that day's landing- thread creep I realise, it's not compulsory.)
