Crew communication
672 lines readobservations a human-factors reviewer takes from a transcript — the sterile cockpit, the Board's own notations, rhythm, CRM markers. Not emotions, not scores: the affect is in the audio, and the audio is sealedWindows: 10:30:19–10:47:16, 11:11:47–11:23:09 · basis: recorder pressure altitude below 10,000 ft. Candidate non-pertinent lines below are a first reading for the investigator, not a finding; “@” marks the Board's own non-pertinent-word notation.
