Fuel RKA Questions Flashcards
When must the FUEL XFEED knob be set to OFF?
• For takeoff, go-around and landing flight phases
(AOM 9-10-30 & AOM 2-36)
Which MFD page provides a visual representation of the fuel system operation and parameters?
• The FUEL synoptic page {AOM 9-10-30)
What color does the total and individual tank quantities and fuel temperature indications indicate when in the normal operating range?
• Green (AOM 9-10-30)
When the total fuel quantity is displayed in red, which aural warning is played twice?
• “FUEL”. (AOM 9-10-30)
Can fuel be transferred from one wing to another?
• No (AOM 9-10-50)
How does the crossfeed valve allow corrections in the event of a fuel load imbalance?
• It allows both engines and/or the APU to be fed by one tank (AOM 9-10-50)
Which CAS message is displayed on the EICAS when the difference between the current and expected fuel quantities is higher than 880 lb (400 kg) for 5 minutes?
• The amber FUEL LEAK SUSPECTED CAS (AOM 9-10-50)
How many fuel pumps does each fuel tank have?
• Two DC fuel pumps (main (A) and backup (B)) and two scavenge pumps
(AOM 9-10 50)
What controls the main (A) pump when the fuel pump is in the AUTO position?
• The engine ECU (AOM 9-10-50)
What controls the backup (B) pump when the fuel pump is in the AUTO position?
• The FCU (AOM 9-10-50)
List the Four times when the backup (B) pump will be automatically commanded to ON when the fuel pump is in the AUTO position:
- During Engine Start
- APU Start or Run,
- Fuel Low-Pressure Detection
- When the Main (A) Pump Fails
(AOM 9-10-50)
When will the amber FUEL WING IMBALANCE CAS message be displayed on the EICAS?
• When the Fuel Imbalance between tanks is higher than 510 lb
(230 kg)
(AOM 9-10 SO)
Where is the pressure refueling point and REFUELING/DEFUELING control panel located at?
• In the forward portion of the right wing, next to fuselage
(AOM 9-10-50)
How long does the system pre-check on the REFUELING/DEFUELING panel take to verify fuel system operation?
Approximately 10 seconds (AOM 9-10-50)
Which switch located on the REFUELING/DEFUELING control panel enables pressurized refueling to be performed with the airplane energized by either the APU/GPU or batteries power?
• The POWER SELECTION switch (AOM 9-10-50)
