Unfortunately there is no checklist to determine a failed ADIRU.
So no QRH for that.
Perhaps because the built-in (continuous) test system will generate flags and remove data on your instruments.
Comparing your indications (at least with a 737) has been identified by the manufacturer as incorrect.
Well, I'm not going to argue with that
The FO and Aux probes are on the same side, birdstrike could have affected both at the same speed leaving the reliable one (captains) looking erroneus.
I would expect other symptoms in this case, especially if the bird was big enough to block two pitot tubes
