What defines a restrictive discrepancy?

A restrictive discrepancy is best defined as a situation that affects one or more missions but does not lead to a complete shutdown of operations. This means that while the discrepancy presents a challenge or limitation, it still allows for certain missions or functions to continue under specific conditions. For example, a vessel may have a malfunction that requires a change in operations or additional precautions, but it can still carry out certain missions safely.

The ability to proceed with some missions, despite the existence of a discrepancy, highlights a difference in the severity of operational impacts. In a restrictive discrepancy scenario, operators can often implement workarounds or mitigations that keep them operational, making it possible to maintain some level of functionality until the issue can be fully resolved.

Other options describe scenarios that do not align with the definition of a restrictive discrepancy. For example, a fault that allows all missions to proceed suggests that there is no impact on operations at all, which does not fit the restrictive nature. Similarly, a discrepancy that is easily remedied may not limit operations but instead suggests a minor issue requiring simple corrective action. Lastly, a situation prompting immediate evacuation represents a critical and urgent condition that significantly disrupts normal operations, which contrasts sharply with the more controlled environment described by a restrictive discrepancy.
