The cockpit voice recorder captures

  • A.Passenger cabin announcements only
  • B.Crew speech, radio calls and ambient flight deck sound
  • C.Aircraft attitude and control positions
  • D.Engine vibration signatures only

Answer: B

The area microphone picks up warnings, switch clicks and airflow noise as well as speech, and that ambient channel is often as valuable as the words. Correlating it with the data recorder is how an investigation reconstructs a sequence.
