I know AOA differs from pitch attitude - it relates to the relatively motion of the airflow to the wing - but is there any inertial component in the AOA calculation ? This question is related to the qantas incident...
If it has an AoA estimator, there could be a link... where a PRIM takes the speed from an ADR and computes a theoretical AoA, which is then compared to the voted AoA... to see if it fits... How it comes up with the theoretical AoA can come from several sources... but I don't have details of this yet... so this could be a wild guess...
