What should crew members do if they notice any irregularities during the operation checks?

Crew members should document and escalate any irregularities they notice during operation checks according to established protocols. This approach ensures that all potential issues are formally recorded and communicated to the appropriate personnel for further evaluation and action. Ignoring irregularities can lead to safety risks and compromise the effectiveness of operations, while addressing them later might lead to unresolved issues affecting current missions. By following protocol, the crew maintains accountability and ensures that any problems are addressed swiftly to uphold operational readiness and safety.
