What does "NO-GO" indicate during system checks?

The term "NO-GO" during system checks indicates that the system has malfunctioned. In the context of operational checks, a "NO-GO" response is used to signal that a specific component, system, or process is not functioning as intended, and corrective actions are required before the system can be deemed fully operational. This classification helps personnel identify issues quickly, allowing them to address malfunctions to ensure overall system reliability and effectiveness.

In contrast, terms like operational or being updated would indicate that the system is either working correctly or undergoing necessary changes, while requiring calibration implies that adjustments are needed to maintain accuracy but not necessarily that the system has failed.
