5 Main 1 Main 2 Center Forward Tank Group Aft Tank Group |
|
|
How many surge tanks are there? |
2 |
|
|
What does the cross feed system do? |
Allow each tank to supply any engine. |
|
|
How many boost pumps do each main tank have? |
2 Fuel Pumps |
|
|
Why is the center tank fuel used before the main tank fuels? |
Supplies fuel at a slightly higher pressure. |
|
|
What do not have fuel boost pumps? |
The auxiliary tanks and integral tanks. |
|
|
What is used to move fuel from the auxiliary tanks to the center tank? |
Pressure differential |
|
|
How are the fuel tanks divided and named? |
Main 1: M1 Left wing Main 2: M2 Right wing Center Tank: CTR/CTR3 Forward Tank Group: FTG Cells #4-6 Aft Tank Group: ATG Cells #7-10 |
|
|

|
|
Main 1 fuel capacity? |
1265 gallons |
|
|
Main 2 fuel capacity? |
1266 gallons |
|
|
Center tank fuel capacity? |
4299 gallons |
|
|
FTG fuel capacity? |
1507 gallons |
|
|
ATG fuel capacity? |
2520 gallons |
|
|
What are the auxiliary tanks? |
The 2 surge tanks (ATG and FTG) which are interconnected body fuel tanks and one integral tank. |
|
|
What does the FTG consist of? |
One master and two extension tanks. #4 most forward, followed by #5 then #6 connecting to CTR3. |
|
|
What does the ATG consist of? |
Three body tanks (#7-9) and one integral tank(#10). Not designed for configuration changes. #7 connects to CTR3 followed by #8, #9, then #10 being most aft. |
|
|
What does the fuel system consist of? |
Fuel Storage Auxiliary Tanks Pressure Refueling
APU Fuel Feed
Fuel Temperature Indicating Air-to-air Refueling Defuel and Transfer Engine Fuel Feed
IDG Oil Cooling Fuel Quantity Indicating |
|
|
What does the Fuel Storage do? |
Hold/supply fuel for engines and APU Provide venting for tanks Provide sump drains |
|
|
What does the Auxiliary Tanks provide? |
Additional fuel storage to extend flight range. |
|
|
What is the Pressure Refueling system used for? |
Used for refueling all tanks, fuel transfer from tank to tank, or defueling. |
|
|
What does the APU Fuel Feed system do? |
Supplies fuel to the APU. |
|
|
What tank does the APU usually get from? |
Main 1 but can be any because of the fuel boost pump switches. |
|
|
What tanks does the Fuel Temperature Indicating system give the temp for? |
M1 M2 CTR3 |
|
|
During air-to-air refueling, fuel from the tanker enters the receptacle in the? |
Universal Aerial Refuel Receptacle Slipway Installation (UARRSI), then flows through the manifold and open master isolation valve into the tanks. |
|
|
What does the Defuel and Transfer system do? |
Removes fuel to the refuel station or can transfer fuel from tank to tank |
|
|
What does the Engine Fuel Feed do? |
Supplies fuel through M1, M2, and CTR3. The auxiliary fuel tanks feed the engine through CTR3. |
|
|
What is the IDG Oil Cooling system and how does it work? |
Integrated Drive Generator (IDG) cooling system is an engine-to-main tank fuel return system. It uses engine feed fuel flow through the fuel-cooled oil cooler (FCOC) on the engine to cool IDG oil. The heated return fuel mixes back in the main tanks. The main tanks control fuel quantity with intermittent fuel transfer from main tanks to CTR3. |
|
|
What is FQIS, what does it do, and where is it displayed? |
(Fuel Quantity Indication System) Measure fuel weight in tanks and is indicated on the primary engine display of the common display system (CDS) and ground refuel panel. |
|
|
What is the OBIGGS and what does it do? |
(On-Board Inert Gas Generation System) Supplies nitrogen enriched air (NEA) to all the fuel tanks to ensure a 9% max oxygen concentration throughout flight. It will reduce fuel tank oxygen concentration to 9% within 40 min during ground startup operations. |
