solution go around or if clever be patient and use smaller stick deflections but knowing how rough the rock can be easier said than done.
Head from a BA mate. He understands that on the approach, Captains landing, so Co Pilot handling the approach-BA SOP. At some point a double R Alt. fault/indication occurred which put the aircraft into Direct Law. (aircraft handles like a normal non FBW plane)
The co-pilot flew the Wind Sheer Go-around. (Capt. hadn't resumed control for the landing) and with little practice in "manual flying" in those conditions, over controlled the sidestick inputs, resulting in the 30deg PIO.
Situation was resolved when the gear selected up, which presumably removed the R Alt fault signal and returned the aircraft to Normal FBW Airbus handling.
I'm not Airbus qualified so excuse the neccesarily rather non technical description.
