What does EICAS display show for scavenge ejectors?

• A. One shown, but there are two for each shown
• B. All four ejectors
• C. Only two ejectors are shown
• D. None of the ejectors are shown

Answer: (A)

The EICAS display is designed to present engine subsystems in a clear, consolidated way. For the oil scavenge system, there are two scavenge ejectors per engine to ensure adequate oil return and redundancy, but the display shows a single scavenge ejector indicator per engine. This single symbol represents the overall status of the scavenge system rather than each individual ejector. If something affects the scavenge path, the system will flag it through the relevant advisory or warning tied to that circuit. So you’ll see one scavenge ejector indication per engine, even though two ejectors exist in each engine.
