Concerning the fuel system, the INCOR- RECT statement is: a) The FUEL BOOST pump switches do not have to be on for engine start. b) With the FUEL BOOST pump switches off, the respective boost pump will automatically be energized whenever the respective START button is depressed, or when crossfeed from that tank is selected. c) It is normal for both fuel boost pumps to operate during crossfeed operation. d) The fuel boost pump Will be automatically energized anytime the FUEL BOOST switches are in NORM and the START button is depressed, crossfeed is selected, or low pressure (5 psi) is sensed in the engine supply line (throttle at IDLE or above).
After engine start, the fuel boost pump is deenergized by: a) The FUEL BOOST pump switch. b) Start circuit termination. c) Discontinuing crossfeed. d) A time delay relay.
Concerning the fuel system, the correct statement is: a) In the event of DC power loss, the primary ejector pump ceases to operate and the engine flames out. b) The respective engine should be shut down if the respective FUEL FILT BYPASS annunciator illuminates. c) The FUEL BOOST switches should be on for takeoff and landing. d) The fuel filters should be inspected prior to the next flight if the FUEL FLT BYPASS light illuminates.
If the L or R FUEL BOOST ON annunciators illuminate without any action by the crew (engine operating normally), the probable cause is: a) The engine-driven fuel pump has failed. b) The firewall shutoff valve has closed. c) The low pressure sensing switch has energized the boost pump. d) The fuel flow compensator has energized the boost pump below 5 psi.
To verify that crossfeed is in fact occurring, it is necessary to: a) Monitor the FUEL QTY indicators for appropriate quantity changes. b) Only observe that the INTRANSIT light is out. c) Ensure both FUEL BOOST ON lights are illuminated. d) Ensure that the FUEL BOOST pump switch for the tank being fed is on.
When crossfeed is selected by positioning the crossfeed switch to LH TANK, and the green INTRANSIT light stays on: a) This is normal. b) The boost pumps did not actuate. c) One or both crossfeed valves did not fully close. d) One or both crossfeed valves did not fully open.
Operation of the primary ejector pump is directly dependent upon: a) DC electrical power. b) High pressure fuel from the engine driven fuel pump. c) AC electrical power supplied by the No. 1 or No. 2 inverter. d) Flow from a transfer ejector pump.
If the engine-driven fuel pump fails: a) The engine will flame out. b) The primary ejector pump will fail also, but the boost pump will be energized by low pressure and will sustain the engine. c) The transfer ejector pumps will also be inoperative. d) Crossfeed must be selected in order to obtain high-pressure motive flow from the opposite engine.
If crossfeed has been selected and main DC electrical power is lost (battery switch in EMER with a dual generator failure): a) The system will remain in crossfeed. b) The crossfeed valves will fail closed. c) Both boost pumps will be energized to terminate crossfeed. d) The motive flow shutoff valve Will fail open.
