What creates Motive Flow?
Motive Flow is created by the Engine Driven Fuel Pumps
How is the fuel transferred from the Center Tank to the Main Wing Tanks? And when does the auto cross flow process begin/end?
Fuel moves from the Center tank to the Main Wing Tanks using the Transfer Ejectors and Transfer SOV.
This process begins when the Wing Tank falls below 93% and stops when the Wing Tanks are full.
How does the fuel move from the Main Wing Tanks to the engines?
From the Wing Tanks, fuel moves to Collector Tanks via gravity and Scavenger Ejectors.
Fuel moves from the Collector Tanks to the engines via the Main Ejectors backed up by the Fuel Boost Pump.
As part of the checklist, prior to starting the engines, you reach up and select the L Fuel Boost Pump. You then observe that “ON” indications have illuminated in both pump switches (without selecting R Fuel Boost Pump). What is going on? Why did this happen?
Selecting the Fuel Boost Pumps in “arms the fuel pumps to look for low pressure”, it does not turn them on.
Once armed, if either Fuel Boost Pump finds low pressure on its respective side, both fuel boost pumps turn on together.
Why are the pressure refueling limits higher than the gravity refueling limits?
Because the gravity fuel caps are located below the highest part of the wing tank.
Describe the automatic power crossflow process.
The crossflow process starts when one wing tank is below the other wing tank by 200 pounds.
It turns off when the originally low tank exceeds the other tank by 50 pounds.
How would you manually crossflow fuel should the automatic crossflow fail?
By selecting XFLOW AUTO OVERRIDE switch-light and then selecting the crossflow SOV on the low-fuel side.
Push the side to where you want the fuel to go!
Why do you have to be especially careful during manual crossflow?
There is no automatic protection available.
This could create an imbalance through continuous use
What is the maximum fuel imbalance limit?

800 pounds maximum fuel imbalance
Fuel Imbalance Caution Message
What indications would you receive if the Refuel / Defuel computer was left on after refueling?

The fuel stored in the wing could be as cold as -30°C. Per limitation, fuel entering the engine can’t be lower than 5°C, how are we able to meet this limitation?
The Fuel/Oil Heat Exchanger warms the fuel prior to entering the engine fuel metering unit.
What is an MLI and why would we use them?
Magnetic Level Indicator
Serve as the manual method of checking the fuel using the two accelerometers located in the flight deck (to determine lateral and horizontal axis tilt when on the ground)
What prevents fuel from flowing to the outside of the lower wing during turns?
One-way flow valves (flapper-valves).
