While AoA disagree probably would not have been a help to the pilots had it been working on the penultimate LionAir flight the AoA problem would have been logged and hopefully led to AoA problem resolution before the fatal flight.
I say hopefully since I am not impressed with troubleshooting flow that "followed the steps" but did not actually identify a root cause.
