It was expected that a response to inappropriate MCAS would be autopilot off, autothrottle off, manual trim to correct to neutral trim then stab trim off and fly the plane. Perhaps certification should not rely on the crews following these NNC and other checklists?
If certification wants to rely on crews following NNC and checklists, certification must ensure that pilots are adequately informed about and trained on new failure modes. Would you say initial certification of the MAX has succeeded in this?
