Also, why does one AOA differ from the other when they eventually track each other with a constant offset; it can't be a graph offset often seen in NTSB graphs. Can someone clarify this.
if one vane was damaged such that the vane was reading offset from its hub, the readings would be consistent, they would be deflected the same by the airstream, but one would have a bias “x” degrees offset from hub. Or, the indexing pin could be un-mated with its receptacle. Improper install.
