Hydraulics Flashcards
The ECAM HYD page display shows that:
The ENG 2 FIRE pb has been pressed.
True of False: In the Yellow system, hydraulic fluid is currently prevented from flowing to the engine driven pump. Based on the ECAM, the Yellow hydraulic system is being pressurized via the ELEC Pump.
False
The Green hydraulic system can be pressurized by:
The #1 engine-driven pump or the PTU.
The Yellow hydraulic system can be pressurized by:
The #2 engine-driven pump, the PTU, an electric pump or a hand pump.
The Blue hydraulic system can be pressurized by:
An electric pump or a RAT-driven pump.
When there is a hydraulic system non-normal, the ______will also alert the pilots.
E/WD
When the PTU is operating:
Pressure transfers between the Green and Yellow systems.
Once deployed, how can the RAT be stowed?
Only on the ground by maintenance personnel.
What are highlighted in this ECAM HYD page display?
Reservoirs
What are highlighted in this ECAM HYD page?
Fire shutoff valves
And finally, what are highlighted in this ECAM HYD page?
Engine-driven pumps
What does the highlighted area on the ECAM HYD page reflect?
System is operating normally
What does the highlighted area now show on the ECAM HYD page?
The display changes to amber to indicate that pressure has dropped below a preset threshold.
When there is a hydraulic system non-normal, the ______will also alert the pilots.
E/WD
What does this indication mean on the ECAM HYD Page?
Normal hydraulic fluid quantity
Before the engine is started, if the pointer is below the green box, then:
The hydraulic system requires servicing.
If the pointer turns amber and is in the amber box, then:
The fluid level is low.
The Green hydraulic system can be pressurized by:
The #1 engine-driven pump or the PTU.
The Yellow hydraulic system can be pressurized by:
The #2 engine-driven pump, the PTU, an electric pump or a hand pump.
The Blue hydraulic system can be pressurized by:
An electric pump or a RAT-driven pump.
This ECAM HYD Page shows the PTU in the:
Standby mode.
The ECAM HYD Page now shows the PTU:
Activated, pressurizing the Yellow system.
When the PTU is operating:
Pressure transfers between the Green and Yellow systems.
Toward what is the yellow arrow pointing?
Ram Air Turbine
This ECAM HYD Page shows:
The RAT is extended, pressurizing the Blue system.
