PUD SOD
Pitot blocked speed under reads in the descent. Thus over reads in climb. So the higher you climb the greater the over speed error until the Airbus normal law over speed corrections kick in and pitch up the aircraft until it stalls. Usual scenario in SIM is on take off.
I love the QRH statement "level off for troubleshooting".
In my mind if the protections stop you levelling off to troubleshoot turn 2 ADR,s off set a sensible pitch/pwr setting. CONF 1,2,3.... 7.5/57% but if CONF 1+ F pitch about 3.5. That's what I have in the back of my head.
Easier said than done as startle factor huge.
