When both consoles have EQUIP CONTR off, what is displayed?

• A. Generally, fault alerting is suspended. However, in the case of the radar at the ECS, faults that persist will be reported as faults on both consoles when the filter condition is satisfied
• B. Fault alerting continues normally on both consoles
• C. The system performs a complete fault report to the maintenance desk
• D. No faults are displayed at all on either console

Answer: (A)

When EQUIP CONTR is turned off, fault alerting is generally suspended to avoid alarm clutter while equipment control is not active. The system doesn’t routinely display faults on the consoles under these conditions. The exception is the radar at the ECS: if a fault persists and meets the filter condition, those faults will still be reported on both consoles. This persistence/filter mechanism ensures that important, enduring issues with the radar at the ECS aren’t hidden even when normal fault alerts are suppressed. So you’d see no regular faults, but persistent radar-at-ECS faults that satisfy the filter would appear on both consoles.
