Due to the faulty information sent by two of the AoA sensors, it is probable that the speed tape as presented to the crew was erroneous, bringing some confusion. The indicated airspeed was correct, but the protection speeds which are based on aerodynamic data were misplaced.
The FACs have been duped by the AoA sensors for the representation of the protection speeds on the PFDs. The ELACs have been duped as well, as the protections did not activate.
