Scary. G
I would certainly hope so. I don’t know if Boeing has been provided with any of the FDR data from the Ethiopian flight as of yet which might show a similar AOA error as experienced in the first incident.
I don’t know how the AOA sensor data is processed in a 737 specifically, or what differences may exist in the processing between an NG and a Max. I doubt that the AOA position comes off of the sensors in digital form - typically it is either a variable DC voltage or variable AC waveform, with conversion to digital at some point downstream.
