The angle of attack decoding function as specified in the documents provided by the operator

Supposing the AOA probe (or some component downstream) was the wrong part number. Then you would very likely have this type of effect on the AOA flight data. Hopefully the maintenance records will give a clue on this.
The ominous part is: what else might be receiving bad AOA data?
