The certification judgement should involve crew workload, conflicting alerts, ambiguity, and distraction; consideration of the wider situation, risk of assumption, and comparison with additional tasks on top of a range of normal procedures. Thus it could be argued that the 737 requires a different approach, this could involve training or from what has been learnt for these accidents, reconsidering the overall system - AoA, speed correction, low speed awareness, alerts …
