Final answer:
The PIC must prioritize FAR or civil aviation rules over Metro policies or procedures when making decisions related to flight safety, as federal regulations take precedence in such situations.
Step-by-step explanation:
If the Pilot in Command (PIC) must make a decision relating to the safety of flight and there is a conflict between a Metro policy or procedure and a Federal Aviation Regulation (FAR) or other civil aviation rule, the PIC is required to prioritize and follow the FAR or civil rule. In matters of safety, federal regulations and civil aviation rules take precedence over company policies or procedures. It is the responsibility of the PIC to ensure the safe operation of the flight. This may mean deviating from Metro policies if they conflict with regulatory requirements that are established to maintain the highest level of safety.
