Manual transfer from the central tank to the “inner” tanks by means of the “CTR MAN XFR” switch originates: Opening of the "inlet valves" of the "inner" tanks if there is no "high level" condition in the tanks related. Opening of the "inlet valves" of the two "inner" tanks. Opening the "inlet valves" of the two "inner" tanks and opening the "trim pipe isolation valve".

In normal operation, each “FCMC” collects data from the fuel / peripheral system and: Only the FCMC 1 receives direct signals from the fuel probes. The two “FCMC's” are active and are redundant. “FCMC 1” is the control unit and “FCMC 2” is the monitoring unit.

In the “Refuel Panel” during an automatic supply, when the “high level” test is performed: They close the "inlet valves" of tanks that are not in "high level" condition. It takes the tanks in “high level” condition for transshipment. They just turn on the “high level” lights.
