The Incident as a Situational example

You are the captain flying a scheduled transoceanic flight. You take off shortly after midnight with 8 tons of fuel more than the minimum quantity required. The flight progresses normally. Following standard operating procedures (SOPs), you review the system pages and fuel burn-off at regular intervals. In the very early morning hours, during one of these checks, you notice an unusual oil indication for the right engine. In order to diagnose the reason, you contact the airline’s maintenance control center (MCC) by radio, but the people there cannot explain the anomaly.

You then get an advisory message on the system display indicating a fuel imbalance between left and right wing inner tanks. In response, you apply the fuel imbalance procedure from memory because you have frequently been trained to monitor fuel imbalance. You select the cross-feed valve “OPEN” and the right wing fuel pumps “OFF” to feed the right engine from the left wing tanks.
