As to situational awareness, from that link to Endsley:
"In actual practice, however, long term memory structures can be used to circumvent the limitations of working memory. "
"Where scripts, set sequences of actions, have been developed for given situation conditions, much of the load on working memory for generating alternate behaviors and selecting among them is also diminished."
"Of prime importance is that this process can be almost instantaneous due to the superior abilities of human pattern matching mechanisms."
Where does the responsibility to commit sequences of actions and the underlying patterns to long term memory lie?
What if those materials were labeled as "Memory Items"? Should the users be expected to memorize them in proximity to a disaster that occurred recently?
What if the airline, recognizing they had taken no relevant training action or confirmation action, had parked the plane until Boeing produced the updated software or the pilots demonstrated what Endsley said was the appropriate action for them to have taken?
In hindsight it was a terrible idea to allow the AoA system to produce valid, but incorrect AoA data. In hindsight it was terrible the FAA approved that.
