What is the purpose of reviewing the ADB?

Reviewing the Aircraft Discrepancy Book (ADB) is crucial because it allows personnel to identify and confirm that any discrepancies or issues noted with the aircraft have been properly addressed and are within established limits. This process is essential for maintaining aircraft safety and operational readiness. The ADB serves as a record of maintenance actions taken and ongoing issues, providing a clear history of the aircraft's status. Ensuring that discrepancies are managed effectively helps prevent potential safety risks and ensures that the aircraft can perform its intended mission reliably.

The other options, while relevant to flight operations, do not specifically address the primary function of the ADB. Keeping flight plans updated, tracking piloting hours, and managing flight schedules are important aspects of aviation operations, but they are not the main focus of the ADB's purpose, which is specifically concerning the condition and discrepancies of the aircraft itself.
