                                    CENTRE TANK FUEL PUMPS
                                    Centre tank fuel pump switches must not be "ON'' unless personnel are available in the flight deck to monitor low PRESS lights.
                                    For ground operations prior to engine start:  The centre tank fuel pump switches must not be positioned ON unless the centre tank contains usable fuel.  With centre tank fuel pump switches ON, verify both centre tank fuel pump low PRESS lights are illuminated and EICAS CTR L FUEL PUMP and CTR R FUEL PUMP messages are displayed.

   For ground operations after engine start and flight operations:  The centre tank fuel pump switch must be selected OFF when the respective CTR L FUEL PUMP or CTR R FUEL PUMP message displays.  Both centre tank fuel pump switches must be selected OFF when either the CTR L FUEL PUMP or CTR R FUEL PUMP message displays if the centre tank is empty.  During cruise flight, both centre tank pump switches may be reselected ON whenever centre tank usable fuel is indicated.
