18
Q

List some items that are powered by the BLUE system.

(FCOM-DSC-29-10-30)

A

a. Slats

b. Emergency generator

19
Q

What does an amber FAULT light in the PTU push button indicate?

(FCOM-DSC-29-20)

A

OLL

Overtemp in reservoir

Low air pressure in the reservoir

Low quantity in the reservoir

20
Q

What does an amber FAULT light in the ENG PUMP pushbutton indicate?

(FCOM-DSC-29-20)

A

POLL

Pump pressure low

Overtemp in reservoir

Low air pressure in the reservoir

Low quantity in the reservoir

21
Q

What does a FAULT light in the BLUE or YELLOW ELEC PUMP pushbutton indicate?

(FCOM-DSC-29-20)

A

POLLO

Pump pressure low

Overtemp in reservoir

Low air pressure in the reservoir

Low quantity in the reservoir

Overheat of pump

22
Q

What is the function of the hydraulic priority valves?

(FCOM-DSC-29-10-10)

A

Hydraulic power to the flaps, slats, landing gear, and emergency generator is cut off if pressure drops below a predetermined value. (High demand items)

23
Q

What is the purpose of the hand pump?

(FCOM-DSC-29-10-20)

A

To provide Yellow hydraulic pressure for cargo door operation

24
Q

When brake accumulator pressure is low, how is it recharged?

(FCOM-DSC-32-30-10)

A

With the Yellow hydraulic system electric pump

25
Q

How do you verify the Parking Brake is set?

(FCOM-DSC-32-30-20)

A

a. ECAM PARKING BRK memo
b. Triple indicator brake pressure

26
Q

If the parking brake is activated and no yellow hydraulic or accumulator pressure is available, do you still have available braking?

(FCOM-DSC-32-30-10)

A

Yes, via the brake pedals, but you must have green hydraulic pressure

27
Q

How we do charge the yellow system accumulators?

(FCOM-DSC-32-30-10)

A

Pressing the yellow hydraulic electrical pump pushbutton
