Q

347

With fuel in the center tank, when do the Center Tank Pumps run with the MODE SEL in AUTO?

A

With fuel in the Center tank:
1) Center pumps run for 2
minutes at each engine start
2) Before or after engine start
sequence, the pumps run if
the slats are retracted.

Center tank pumps stop 5 mins after tank empty (low level reached)

2
Q

What is represented by a FAULT light in the
Center Tank MODE SEL pushbutton?

A

Center tank has more than 550
lbs of fuel and the Left or Right
wing tanks have less than
11,000 lbs
(Telling pilot that fuel is not transferring from Center to Wings)

3
Q

In flight, with fuel in both wings tanks, if all tank pumps
failed, would the engines continue to run? Why or Why
not?

A

YES
Gravity Feeding is available from both wing tanks.

4
Q

In cruise your Yellow hydraulic system
experiences a low quantity. In addition to the
ECAM, what lights would illuminate on the
overhead panel?

A

PTU FAULT
ENGINE 2 PUMP FAULT

5
Q

If the ENG 1 PUMP Fault light illuminates due to
low Green System pressure, can the PTU be
used to pressurize the Green System?

A

YES

(Green can pressurize Yellow and vice versa)

6
Q

After selecting the affected pushbuttons OFF,
what failure could cause the FAULT lights to
remain lit?

A

GREEN SYSTEM RESERVOIR
OVERHEAT

7
Q

What does the WING FAULT light represent?

A

ANTI-ICE VALVE NOT IN
REQUIRED POSITION
OR
LOW PRESSURE DETECTED

8
Q

When are the PROBES/WINDOWS heated
automatically?

A

INFLIGHT
OR
ON THE GROUND WITH
AT LEAST ONE ENGINE
OPERATING
(Except TAT Probes)

9
Q

349
Does Center Tank fuel on the A321
directly feed the engines?

A


NO.

Primary difference = 320 fuel goes directly to engines, 321 fuel goes to wing tanks

10
Q

351

What is indicated by a FAULT light in
a FUEL PUMP switch?

A

Illuminates amber with ECAM caution when delivery pressure drops

11
Q

353

If a fuel pump FAULT light illuminates in flight, what will allow the engines to continue to run?

A

YES –Gravity Feed

12
Q

What is indicated by the white ON X FEED light?

A

In transit –valve is opening

13
Q

357
What is indicated by the blue OPEN X FEED light?

A

Valve is fully open

14
Q

In flight, with fuel in both wing tanks, if all tank pumps failed, would the engines continue to run?

A


Yes

Gravity feed from wing tanks ONLY

15
Q

361

On the A-321
With the MODE SEL in the AUTO position
and fuel in the center tank,
will fuel feed directly to the engine from the center tank?

A

No. Fuel transfers from the center tank to the wing tanks to feed the engines.

16
Q

On the A-321, What is represented by a FAULT light in the Center Tank MODE SEL pushbutton?

A

With the MODE SEL pbin AUTO, Center Tank Fuel is not being transferred to the wing tanks when it should be. (The center tank has more than 550 lbs. of fuel and the left or right wing tank has less than 11,000 lbs.)

17
Q

If the RAT is extended by the hydraulic RAT MAN ON pb:
What hydraulic system is powered by the RAT?

A

Blue hydraulic system

18
Q

367
If the RAT is extended by the hydraulic RAT MAN ON pb,
will the electric EMER GEN couple to the aircraft electrical system?

A

No

19
Q

If the Y Electric Pump is not turned on during a One Engine Taxi, what Hydraulic Systems are powered once the Parking Brake is selected ON?

A

Just Green and Blue are powered. Yellow System would not be powered with 1 Engine Master ON and Parking Brake ON. PTU is inhibited in this configuration.

20
Q

If you forget to turn on the Y Electric Pump during
One Engine Taxi, the G & B systems will still be powered. Which hydraulic system(s) will operate if the Parking Brake is selected OFF?

A

All hydsystems are powered. Yellow System powered through PTU with 1 Engine Master ON and Parking Brake OFF.

21
Q

After parking at the gate, the PTU will operate upon shutdown of the second engine until or unless what occurs?

A

Cargo door operation or no longer a >500 psi differential between the green and yellow systems upon spool down of engine 2

22
Q

What could cause the PTU FAULT light to illuminate?

A


1 The green or the yellow reservoir overheats.
2 The green or the yellow reservoir has low air pressure.
3 The green or the yellow reservoir has low fluid level.
The FAULT light remains illuminated if the overheat is active.

23
Q

377
In flight, when will the PTU operate with the Pbin AUTO

A

The PTU operates automatically when the differential pressure between the green and yellow system is more than 500 PSI

24
Q

With the RAT MAN ON pbarmed (guarded),
when will the RAT deploy automatically?

A

The RAT will automatically extend if both AC 1 and AC 2 are lost and the airspeed is >100 knots

25
Q

381
What will occur when the RAT MAN ON pb
is pressed?

A

1.
RAT will deploy (even on the ground)
2.
Blue System pressure will be restored

26
Q

What is the difference between pressing
the RAT MAN ON button on the HYD panel vs.
the MAN ON button on the EMER ELEC PWR panel?

A

Electrics will not couple

27
Q

When is the PTU inhibited?

A

The PTU is inhibited:

First engine start

One ENG Master ON & PARK BRK set

NWS DISC displayed on ECAM

Cargo Door Operation

28
Q

When is the PTU automatically tested?

A

The PTU is automatically tested during the second engine start

29
Q

389
You experience a G RSVR OVHT ECAM Caution.
After completing the non-normal procedure,
the FAULT lights (below) remain illuminated,
but then extinguish several minutes later.
When the lights extinguish, what does this indicate?

A

The overheat condition has abated

30
Q

391
Prior to starting ENG 2 during a one engine taxi;
why is the Y ELEC PUMP turned OFF?

A

Permits automatic PTU test during second engine start

31
Q

393
Why is the hydraulic YELLOW ELEC PUMP required to be turned ON during One Engine taxi?

A


Prevents PTU operation while taxiing (noisy); due to no pressure differential

Hydraulic pressure source for YELLOW system braking

32
Q

397

A

Open

33
Q

With loss of electrical power,
in which position do the wing anti-ice valves fail?

A


Engines: Open

Wings: Closed
