What are the three HYD systems called?
- GREEN, BLUE and YELLOW Systems
How is each hydraulic system normally powered?
- GREEN: engine driven
- BLUE: electrically driven
- YELLOW: engine or electrically driven
When does the BLUE pump normally operate?
- After the first engine is started
If the BLUE system lost pressure, how would pressure be restored?
- The RAT must be deployed
- It does not deploy automatically upon BLUE system pressure loss, so if needed, it must be manually deployed with the RAT MAN ON pushbutton.
What can be done to correct low ACUM PRESS indication?
On the ground, coordinate with ground personnel and turn on the beacon and YELLOW ELEC pump
With no HYD system power, how can the FWD CARGO door be opened?
By using a hand pump
What causes the PTU to operate if in AUTO?
- Differential pressure of 500 psi between GREEN and YELLOW systems
When is the PTU inhibited?
- On the ground with ENG MASTER levers split and either the nose wheel steering disconnected or the parking brake ON
- For 40 seconds after cargo door is operated
What are some users of the GREEN system?
- Landing gear
- Normal brakes
- Slats and flaps
- ENG 1 thrust reverser
What are some users of the BLUE system?
- Emergency generator
- Slats
What are some users of the YELLOW system?
- Flaps
- NWS
- Alternate brakes
What do the priority valves do in the HYD systems?
Removes hydraulic power from the heavy users and protects the flight controls
What would cause a FAULT light in the ENG 1 PUMP on the HYD panel?
- Pump low pressure
- Over temp in reservoir
- Low reservoir air pressure
- Low reservoir quantity
If the FAULT light illuminates in the ENG 1 pump, what would identify the specific reason for the FAULT?
ECAM will display the reason
