When an airplane crash occurs, the cockpit voice recorder (CVR) and flight data recorder (FDR), commonly known as “black boxes,” play a crucial role in understanding the cause. After the Air India Flight 171 accident, these devices became central to the investigation.
The CVR records sounds from the flight deck, including pilot conversations, alarms, and background noise. The FDR logs hundreds of technical parameters such as speed, altitude, engine performance, and control inputs. Together, they provide investigators with a detailed timeline that can reveal whether mechanical issues, human error, or other factors were involved.
Aviation attorney Mike Andrews highlighted the importance of transparency in investigations: “Nobody can blame the pilot without a thorough investigation.” He emphasized that full disclosure protects both victims and aviation safety culture.
Experts note that partial or selective release of black box data can lead to speculation and misinformation. Families affected by crashes are entitled to complete analysis of CVR and FDR data so they can understand what happened. They also have the right to request official summaries through investigative authorities; independent reviews may require legal assistance.
Investigators follow several steps when using black boxes: first recovering them from crash sites—since they are built to survive severe impact and fire—then extracting encrypted recordings in specialized labs. Audio from the CVR is matched with FDR metrics and air traffic control logs before experts validate findings for accuracy.
Common questions about black boxes include how long it takes to decode them—initial data may be available within days but full analysis often requires weeks or months depending on damage—and why they are called “black boxes” despite being painted orange for visibility after crashes.
