As has been previously discussed - the measured AOA and the measured static pressure is used to compute an AOA-corrected static pressure. Airspeed is then calculated based on the difference between the dynamic pressure measured at the Pitot tube and the AOA-corrected static pressure. If you loose AOA, you loose AOA-corrected static pressure, and anything that uses it in it's calculation becomes unreliable.
