Where will a pending oil filter bypass or oil chip detection alert be indicated?

• A. EICAS system
• B. Panel in the AFT equipment bay
• C. Central maintenance system
• D. Cockpit cabin display

Answer: (B)

The key idea is where lubrication-system warnings are first shown and tracked. Oil filter bypass and oil chip detector alerts are part of the engine’s lubrication monitoring and are typically displayed on the panel located in the aft equipment bay. This panel is used for maintenance and engine-room annunciations, including pending conditions, so crews or technicians can see and address them before they escalate to a full cockpit warning.

The EICAS system generally shows active faults that affect flight operation, not necessarily pending lubrication alerts. The central maintenance system stores fault history and data for maintenance review rather than providing real-time flight deck indications. The cockpit cabin display is for cabin-related information, not engine lubrication alerts. So the panel in the aft equipment bay is the proper place for a pending oil filter bypass or oil chip detection alert.
