Which phrase best completes the statement: "Failure of the left forward ejector, aft cell ejector or both boost pumps will result in trapped fuel and the only indication to the aircrew will be illumination of the corresponding ________ warning on the EICAS page"?

• A. FUEL BALANCE
• B. PUMP WARNING
• C. FUEL GAUGE
• D. FEED TANK

Answer: (D)

When fuel cannot reach the engines because a left forward ejector, an aft cell ejector, or both boost pumps have failed, fuel becomes trapped in the associated cell and cannot feed the pumps. The warning that appears on EICAS in this situation is a dedicated FEED TANK indication. This warning is specifically used to alert the crew to a problem with the fuel feeding system, not merely a quantity issue or a general pump fault. The other indicators would not pinpoint a trapped-feed condition: a fuel balance warning would signal an unequal distribution of fuel, a fuel gauge fault would only affect quantity readouts, and a generic pump warning wouldn’t necessarily imply the fuel is trapped in the feed system. So the FEED TANK warning is the correct and most precise indication for this scenario.
