In the review of cockpit voice recorder data, which type of information is typically examined?

• A. Crew conversations and timing of actions.
• B. Engine performance data.
• C. Maintenance logs and service bulletins.
• D. Flight plan origin and routing.

Answer: (A)

Investigators look for what was said in the cockpit and when actions were taken, because the cockpit voice recorder captures pilot and crew conversations, calls, and checklist items, along with the sequence of events as they occurred. This audio timeline shows how the crew communicated, how quickly they recognized and responded to alerts, and whether standard procedures were followed, which is essential for understanding decision-making and coordination during the event.

Engine performance data and other numerical parameters come from the flight data recorder, not the CVR, so they’re reviewed separately to analyze performance trends and system behavior. Maintenance logs and service bulletins are not recorded by the CVR, and flight plan origin or routing isn’t the type of information typically captured by the CVR either.
