My response wasn t intended to distract from IAS readings or scanning in general it was just meant to show that even during the last NTSB briefings the relationship between A T state and FD mode was explicitly highlighted which isn t to suggest that anything failed but rather that human factors seem to have been an issue here like you say that still doesn t explain how 3 pilots managed not to monitor airspeed sufficiently unless instrument readings were way off which we have no reason to believe ATM however this is something that was explicitly mentioned as a possibility by ALPA and the NTSB still didn t evaluate 2 3 of the FDR parameters B777 FCTM B777 FCOM
