Let me ask the question another way...
Since no AOA display exists for the pilots, and AoA is critical to the flight path, how is "UnreliableAoA" not a far more problematic abnormal than "UAS"? Further, once somehow established on the flight deck that AoA is corrupt, how does initiating a UAS failure equate to an acceptable solution?
Two abnormals equal a "NORMAL"?
With apologies to Will Fraser: UAI Unreliable Angle of Incidence....
