OK, now everyone is wondering about ADR, IR and AoA...
I wonder if the AoA estimator now links the ADR and IR together? Shouldn't, but then, perhaps someone can provide the details?
a few days ago DJ77 corrected me about the Qantas AoA spikes (ADR) by adding that these spikes were also present on the IRU channels. And indeed, if you look to the multiple graphs at the end of the Australian report (page 31), you can see a spike on the measured pitch, it came just before (a few tens of millisec ?) the first AoA spike (see page 30, AoA Captain), and it seems correlated (at least in time !) with the AP disengagement. This prompted the IRS failure (page 30), just before the ADR failure. Unless my interpretation of these graphs is as flawed as my understanding of your writings
