|
|
Where is fuel tank 5 and how many parts does it have?
|
2 in total - integral wing center section and the bladder cell fuel tank in the fuselage.
|
|
|
Each tank can supply fuel to its prospective engine or fuel can be supplied from any wing to any engine through a ________ .
|
Cross feed system
|
|
|
How many fuel tanks are on the p-3 and how are they located?
|
From left to right 1-4 plus an auxillary making 5.
|
|
|
Explain the term feathered.
|
The blades are laid flat with the airstream to minimize drag in the event the engine is shutdown inflight.
|
|
|
Where are the engine power levers located.
|
The four pilot levers are installed as a group on top of the center console at the flight station and the copilot levers are similarly grouped on the right.
|
|
|
What are the basic elements of each power level subsystem?
|
A pair of engine power levers, one for each pilot + copilot.
|
|
|
The engine power level system includes how many subsystems.
|
4 independant subsystems.
|
|
|
P-3 is equiped with how many and what type of engine.
|
Four Engines. T56-A-14 Turboprop.

|
Anti collision lights.
|
|
|
What are the hazard areas around the P-3
|
Propeller Area and Propeller jet blast area.
|
|
|
What is the purpose of the Auxillary Power Unit and when is it used?
|
- Provides pneumatic power required for engine starting and source of air for aircraft environmental control system.
- On the ground and emergency in flight electrical power is provided by the generator. |
|
|
Define the purpose of Bleed Air. P-3 is an___ ____ _____ aircraft.
|
Provides heated and pressurized air from the compressor for the bomb bay heating, engine anti-ice, wing de-ice, oil cooler augmentation, and cross bleed engine starting.
P-3 in an all weather capable aircraft. |
|
|
What does UARRSI stand for, and what is its purpose?
P-8 |
Universal Arial Refueling Receptacle Slipway installation.
- Installed in the crown of the aircraft. - Fuel is transfered through a boom inserted in the receiver. |
|
|
What does OBIGGS stand for and what is its purpose. P-8
|
Onboard Inert Gas generating system - provides nitrogen inriched air. Protects against ballistic missles. Keeps tank at or below 9 percent oxygen level.
|
|
|
Expain the Fueling of a P-3. What is the Fuel capacity?
|
Powered by center point pressure fueling. Wing fuel tank can be fueled through overwing fuel caps. Designed to fill all fuel tanks at two pressure fueling nozzle adapters.
P-3 fueling capacity - 9200 gallons. |
|
|
How many Fueling Systems does the P-3 have and expain the 5th.
|
Contains 4 wing fuel tanks + 1 auxilliary fuselage tank.
Auxilliary contains 2 interconnected tanks. Bladder and integral wing section. |
|
|
Explain the Fuel Tank P-8
|
5 fuel tank groups - Main 1 + 2, center, forward, aft and 2 surge tanks. Works on a cross feed system. When APU is running, fuel comes from main 1.
|
|
|
Fuel Tank P-3
|
Wing tanks are numbered from L to R 1-5. Each tank supplies its prospective engine, can be crossfed. When the APU is running fuel usually comes from tank 2.

Prop has 4 blades. Pitch changing mechanism and fuel control assembly = RPM |
|
|
Define Feathering
|
Blades are laid flat with the airstream to decrease drag while inflight.
|
|
|
Engine Power Level System
|
Engine and props controlled by actuation of the engine power levers.
4 independent subsystems, one for each engine. For each subsystem, a pair of power levers are located in the flight station and move identically. |
|
|
What kind of Engines does the P-3 use?
|
Equiped with for T56-A-14 turboprop assemblies.
|
|
|
Anti Collision Lights
|
