What is the fuel feed sequence in normal operations?

Fuel is always fed to the engines from the inner tanks. The sequence is as follows:

Each inner tank empties down to 4000kg
Trim tank fuel transfers to the inner tanks
Each inner tank empties down to 3500kg
Outer tank fuel transfers to the inner tanks

It always must end up in the inner.

*Discuss the gravity feed capabilities from the different fuel tanks*. **TRIM TANK** If the trim tank **\_\_\_\_\_\_** **\_\_\_\_\_\_** pump has failed, the transfer must be accomplished by gravity. This may be done using either an **\_\_\_\_\_\_** or **\_\_\_\_\_\_** **\_\_\_\_\_\_** method, depending on the failure.

*Discuss the gravity feed capabilities from the different fuel tanks*. **TRIM TANK** If the trim tank **_forward_** **_transfer_** pump has failed, the transfer must be accomplished by gravity. This may be done using either an **_automatic_** or **_manual_** **_transfer_** method, depending on the failure.

*Describe the normal fuel usage process*. **FUEL USAGE** Fuel is always fed to the engines from the **\_\_\_\_\_\_** tanks in the following sequence: * Center tanks transfer into the **\_\_\_\_\_\_** tanks. * The inner tank empties down to approximately **\_\_\_\_\_\_** kg. * The trim tank fuel transfers to the **\_\_\_\_\_\_** tanks. * The inner tank empties down to approximately **\_\_\_\_\_\_** kg. * Outer tank fuel transfers to the **\_\_\_\_\_\_** tanks.

Describe the normal fuel usage process. **FUEL USAGE** Fuel is always fed to the engines from the **_inner_** tanks in the following sequence: * Center tanks transfer into the **_inner_** tanks. * The inner tank empties down to approximately **_4,000_** kg. * The trim tank fuel transfers to the **_inner_** tanks. * The inner tank empties down to approximately **_3,500_** kg. * Outer tank fuel transfers to the **_inner_** tanks.

*Recall the normal trim tank transferring - start conditions*. **_AFT_** In-flight, the **\_\_\_\_\_\_** only starts an AFT fuel transfer when all of the following conditions are met: * **\_\_\_\_\_\_** **\_\_\_\_\_\_** is retracted. * **\_\_\_\_\_\_** are retracted * **\_\_\_\_\_\_** **\_\_\_\_\_\_** is not full. * Aircraft is above **\_\_\_\_\_\_** * Normally only **\_\_\_\_\_\_** aft transfer per flight is accomplished. Unless: * **\_\_\_\_\_\_** CG is > target + **\_\_\_**%. * Trim tank quantity is below **\_\_\_\_\_\_** kg. Fuel for aft transfer is provided by: * The **\_\_\_\_\_\_** tank pumps if it contains fuel, or * By the **\_\_\_\_\_\_** tanks if the center tank is empty.

*Recall the normal trim tank transferring - start conditions*. **_AFT_** In-flight, the **_FCMC_** only starts an AFT fuel transfer when all of the following conditions are met: * **_landing_** *_gear_** is retracted. * **_slats_** are retracted * **_trim_** **_tank_** is not full. * Aircraft is above **_FL250_** * Normally only **_one_** aft transfer per flight is accomplished. Unless: * **_Cruise_** CG is > target + **_2_**%. * Trim tank quantity is below **_3,000_** kg. Fuel for aft transfer is provided by: * The **_centre_** tank pumps if it contains fuel, or * By the **_inner_** tanks if the center tank is empty.

*Recall the normal trim tank transferring - stop conditions*. **_AFT_** To perform the aft transfer the FCMC opens the **\_\_\_\_\_\_** **\_\_\_\_\_\_** isolation valve, which allows fuel from the fueling manifold to flow to the trim tank. The aft transfer automatically stops when: * The actual CG is equal to target minus **\_\_\_\_\_\_**%, or * The **\_\_\_\_\_\_** tank high level sensor becomes **\_\_\_\_\_\_**, or * The **\_\_\_\_\_\_** tank's quantity decreases to **\_\_\_\_\_\_** kg, or * The **\_\_\_\_\_\_** **\_\_\_\_\_\_** pb is set to **\_\_\_\_\_\_**, or * A **\_\_\_\_\_\_** or **\_\_\_\_\_\_** to **\_\_\_\_\_\_** tank transfer is taking place. * **\_\_\_\_\_\_** aft transfers are not possible.

*Recall the normal trim tank transferring - stop conditions*. **_AFT_** To perform the aft transfer the FCMC opens the **_trim line_** isolation valve, which allows fuel from the fueling manifold to flow to the trim tank. The aft transfer automatically stops when: * The actual CG is equal to target minus **_0.5_**%. * The trim tank is **_full_**. * The **_inner_** tank's quantity decreases to **_6,250_** kg. * The **_T TANK MODE_** pb is set to FWD. * A **_center_** or **_outer_** to **_inner_** tank transfer is taking place. * * **_Manual_** aft transfers are not possible.

Recall the normal trim tank transferring process. **FWD** The **\_\_\_\_\_\_** sends a forward fuel transfer signal when fuel the following condtions are met: * Calculated CG = **\_\_\_\_\_\_**. (Forward fuel transfer stops from the computed CG equals target minus **\_\_\_\_\_\_**%.) * The fuel contents of one of the two inner tanks decreases to **\_\_\_\_\_\_** kg. * Forward fuel transfer stops when the fuel content reaches **\_\_\_\_\_\_**kg. * The FMGES Sends a time to destinations signal below the threshold (**\_\_\_\_\_\_** mins or **\_\_\_\_\_\_** mins if **\_\_\_\_\_\_** **\_\_\_\_\_\_** has failed or the aircraft is in below **\_\_\_\_\_\_**. * **\_\_\_\_\_\_** is initiated. * In an **\_\_\_\_\_\_****\_\_\_\_\_\_** configuration.
