What should a pilot do if there are discrepancies found during the Before Start Checklist?

Addressing discrepancies before proceeding is crucial for ensuring safety and operational reliability. The Before Start Checklist is designed to verify that the aircraft is ready for flight, and any discrepancies found during this process could indicate potential issues that may affect the flight's safety.

By resolving these discrepancies, the pilot can prevent problems from arising during the flight. This step is essential as it ensures that all systems are functioning correctly and that the aircraft is airworthy. Taking the necessary time to address any findings reinforces a culture of safety and thoroughness in aviation practices.

While documenting discrepancies can be beneficial for future reference, it does not replace the need to resolve immediate safety concerns. Continuing with the flight as planned without addressing discrepancies could lead to insufficient preparation for safe operation. Similarly, notifying air traffic control might be appropriate in certain contexts, but it does not address the underlying technical issues identified in the checklist. Therefore, prioritizing resolution of any discrepancies is the responsible and necessary course of action.
