Lots of info on AoA sensors and processing for the Perpignan A320 in the BEA report, assume similar for the A330
for example
In straight and level flight, when the Mach greater than 0.75, a comparison between the attitude and the aeroplane angle of attack is made by each ADIRU. A class 3 maintenance message (not presented to crew during flight) is generated if the difference between these two parameters exceeds 0.6 of a degree.
