Block 3 Fuel System Flashcards
What are the 5 Fuel Tank Groups on the P8?
Main Tank 1 Main Tank 2 Center Tank(3) Forward Tank Group(4,5,6) Aft Tank Group(7,8,9, 10) And 2 surge tanks
What system allows fuel to be supplied from any tank to any engine?
Cross Feed System
How many boost pumps are in each of the main tanks?
Each Main Tank has 2 boost bumps.
Main 1
Main 2
Center-used first because it supplies fuel at slightly higher pressure
The Auxiliary tanks and Integral tank do not have boost pumps, what causes fuel to move from these tanks to the center tank?
Pressure Differential

What does the Forward Tank Group consist of?
3 interconnected body tanks (one master and two extension tanks).
What does the Aft Tank Group consist of?
3 body tanks and 1 integral tank which are interconnected to act as one fuel tank.
What is the pressure refueling system used for?
Refueling all tanks and for fuel transfer from tank to tank and for defuel.
What functions does the Fuel storage have?
- Holds fuel for engine and apu
- Supplies fuel to the engine.
- Supplies fuel to the APU
- Provides venting for the Fuel tanks.
- Provides sump drains for the Fuel tanks.

What component provides Air to Air refueling for the P-8A during flight?
Universal Aerial Refuel Receptacle Slipway Installation (UARRSI)
What’s the purpose of the defuel system?
It removes fuel from the Fuel Tank to the refuel station and also permits fuel transfers between fuel tanks.
State the purpose of the Fuel Quantity Indicating System. (FQIS)
It measures fuel weight in the fuel tanks
State the purpose of the Fuel temperature Indicating System.
It measures the Fuel temperature in the main tanks and center tank.
What is the purpose of the On-board Inert Gas Generation System?
It supplies Nitrogen enriched air (NEA) to all of the tanks.
It also ensure a 9% maximum oxygen concentration during flight.
