Hi Guys,

Just so I can understand this a little better, I am reasonably new to type and this threw up some interesting scenarios.

So if my understanding is correct, after initially carrying out the memory drills "AP/FD Disconnect, A/THR disconnect, (in this case) CLB 5" because the pitots had blocked and therefore two ADR's were giving the same but incorrect information (aircraft overspeed) the Flight control protections kicked in and tried to force the nose of the aircraft upward as designed to exit the overspeed condition, but in this unique set of circumstances led toward a stall condition. The only way to get out of this was to switch off two ADRs thus forcing alternate law where manual control of pitch could be reestablished?

Thanks!
