Perpignan was due to pressure washing of AoA probes which is not to be done. Water ingress into No.1 and 2 probes which froze at higher threshold after takeoff. No.3 which correct was kicked out by the rogues. Unscheduled last minute check of low speed protection with gear down airspeed reduced very low and when aircraft dropped wing it transitioned to direct law. The THS auto trimmed full up due to wrong SW threshold of 1&3. In normal law THS stops trimming at alpha prot.
Lastly 447 was beaten to death by 24000 posts on pprune. Nobody can discover anything new that wasn't already.
