|
Can the aircraft be flown with a loss of all hydraulic systems?
|
No, you must have at least one
|
|
|
What occurs when you press the RAT MAN ON pushbutton?
|
The RAT extends providing pressure to the BLUE hydraulic pump
|
|
|
Does the PTU transfer hydraulic fluid?
|
No
|
|
|
How many hydraulic pumps are in the GREEN system?
|
- 1 Engine driven pump
- 1 PTU |
|
|
How many hydraulic pumps are in the BLUE system?
|
- 1 Electric pump
- 1 RAT |
|
|
How many hydraulic pumps are in the YELLOW system?
|
- 1 Engine driven pump
- 1 Electric pump - 1 PTU - 1 Hand Pump |
|
|
When does the BLUE ELEC PUMP operate?
|
- After the first engine is started
- If the BLUE PUMP OVRD pb on the MX Panel has been pressed with no engine running |
|
|
What is normal system hydraulic pressure?
|
3000 psi +/-200
|
|
|
Does the RAT automatically deploy with the loss of BLUE hydraulic pressure?
|
No, it must be deployed manually by the RAT MAN ON pushbutton
|
|
|
If the ACCU PRESS indicator is low, what should you do?
|
Obtain ground clearance then turn ON the YELLOW ELEC PUMP to pressurize the accumulator
|
|
|
What condition will cause the PTU to operate when the pushbutton is in AUTO?
|
A difference of 500 psi between the GREEN and YELLOW hydraulic systems
|
|
|
When is the PTU inhibited?
|
- PTU pushbutton is OFF
- First Engine start - Parking brake is ON and only one ENG MASTER switch is ON - NWS in towing position and parking brake ON - Cargo door operation (PTU is also inhibited for 40 seconds after the end of cargo door operation) |
|
|
If the ECAM actions lead you to turn OFF the PTU for a Reservoir Overheat, will the FAULT light go out?
|
No, not until the overheat condition subsides
|
|
|
If the "FAULT" light in the PTU pushbutton is ON, are there any other indications on the HYD Panel?
|
Yes, FAULT light illuminated in the respective ENG PUMP pushbutton
|
|
|
Can the YELLOW ELEC PUMP run the PTU?
|
Yes
|
|
|
Does operating the cargo door run the PTU?
|
No, it is inhibited
|
|
|
Which systems are not inhibited during cargo door operation?
|
- Alternate Braking
- Engine 2 reverser - NWS (if bypass pin not installed) |
|
|
Name several items that run from only the GREEN system?
|
- Landing Gear
- Normal Brakes - Slats/Flaps - Engine 1 Reverser |
|
|
Name several items that run from only the YELLOW system?
|
- NWS
- Alternate Brakes - Parking Brake - Cargo Doors - Engine 2 Reverser |
|
|
What does an amber "FAULT" light in the PTU pushbutton indicate?
|
- Overtemp in Reservoir
- Low air pressure in the reservoir - Low quantity in the reservoir |
|
|
What does an amber "FAULT" light in the ENG PUMP pushbutton indicate?
|
- Pump pressure low
- Overtemp in the reservoir - Low air pressure in the reservoir - Low quantity in the reservoir |
|
|
What does a "FAULT" light in the BLUE or YELLOW ELEC PUMP pushbutton indicate?
|
- Pump pressure low
- Overtemp in the reservoir - Low air pressure in the reservoir - Low quantity in the reservoir - Overheat of pump |
|
|
Where are the HYD FIRE SHUTOFF VALVES located?
|
Between the respective reservoir and ENG pump
|
|
|
What is the function of they hydraulic priority valves?
|
Hydraulic power to the flaps, slats, landing gear, NWS, and emergency generator is cut off if the pressure drops below a predetermined value (High demand items)
|
|
|
What is the purpose of the hand pump?
|
To provide Yellow hydraulic pressure for cargo door operation
|
