When a unit is not receiving all of its monitored input signals, what does that mean?

• A. No-Go
• B. Operational
• C. Standby
• D. Fault

Answer: (A)

When a unit isn’t receiving all of its monitored input signals, it can’t verify that it has the full set of information it needs to operate reliably. That condition is labeled No-Go, meaning it should not be used until the inputs are restored and the status is confirmed safe. This differs from operational (everything's functioning normally), standby (ready but not actively operating), or fault (a specific fault detected in a component or path).
