I'm not sure that is correct. The Airplane was written up for "IAS or ALT disagree shown after takeoff" and "Feel Diff Press LT ILL" (Feel Differential Pressure Light Illuminated, I think) If I've followed the technical discussion correctly (and I may not have) , both of those may have been caused by bad AoA data, and there may never have been an actual problem with the Airspeed.
