If so, and the right code to avoid the issue was actually installed in the aircraft but deliberately switched off, lawyers for the pax, especially those from the second accident, will have a field day.
The display options that Southwest and others purchased provides digital readout of AOA as sensed by each of the AOA vanes and a light bringing attention to significant disagreement between those two measurements. It is my understanding that the pair of digital displays and the disagree light may be fitted or just the disagree light. The operation of the control laws and the stick shakers that are driven by the AOA vane sensors are the same whether or not these display options are included on the flight deck.
