Cross checked instruments with F/O's and standby, flew pitch and power settings and returned to base. All returned to normal in descent.
I would have a few questions :
Was the ADC failure detected by the system and announced as such ?
Was the AP or the pilot following erroneous FD commands ?
Was the stick shaker justified ?
Thanks
