If an FDR FAIL indication occurs, what is the recommended action?

• A. Continue normal operations
• B. Notify maintenance
• C. Investigate the cause
• D. Ignore the warning

Answer: (B)

When an FDR (Flight Data Recorder) FAIL indication occurs, it is important to notify maintenance. This is because the FDR is a critical component in recording flight data and any failure can impact safety and operational integrity. Alerting maintenance ensures that trained personnel can assess the situation, diagnose the issue, and take necessary corrective actions without further delay. Maintaining operational safety standards is paramount, and promptly addressing any alarms or indications like an FDR failure is crucial for the continued safe operation of the aircraft.

Continuing normal operations could compromise safety, investigating the cause typically falls under maintenance protocols, and ignoring the warning would be negligent. Therefore, notifying maintenance is the most responsible course of action in this situation.
