Systems Question Bank Flashcards
The temperature of each aircraft zone is optimized by means of…..
A Trim Air valve
Under what condition should the pack flow controller be set to low?
With a low passenger load to reduce the amount of bleed air demand and improve fuel efficiency.
The Pack Flow controller is set to NORM and yet the ECAM display shows Pack Flow to be high. How is this possible?
High flow is automatically selected regardless of pack flow selector position because air is being supplied by the APU.
The safety valve protects the aircraft against…

In AUTO the cabin differential pressure is normally controlled by….
The outflow valve
On the ground the cabin should be…
Depressurized
The LDG ELEV has been set manually. What is the value?

False.
Have a look at the FMA. The functions displayed in green on the first line are…
All in active mode as they are on the first line and green.
Have a look at the FMA. The blue LOC is in the armed mode.
True.
A/THR in the blue means it is Armed. Why is there a white box around it?
The A/THR has only become armed within the last 10 seconds and the box is drawn to draw attention to the change.
A/THR in white means it is…
Active.
You notice that some waypoints have a small triangle after the name. What does it mean?

In case of RNP 2 failure, VHF 2 is lost.
False.
The flashing amber MECH light indicates that the interphone system is faulty.
False.
If the battery voltages are below minimum how do you charge them?
I have to switch the external power on and check that the battery pbs are on.
What is the meaning of the green AVAIL light?
External power has been plugged in, you must push the EXT PWR pb to connect it.
Both batteries are now charged by the external power unit. Approximately how long does the charging process take?
20 minutes.
Having started the APU, how can you get the APU generator to power the electrical system?

The High Angle Of Attack protection will override the sidestick input. The pitch will be lowered to maintain 120 kts.
In Normal Law, is there a maximum pitch attitude?
Yes, indicated by the green dashes (A)
How do you interpret the amber crosses on the PFD?
The bank angle protection is lost.
Let’s assume the FO presses his take over pb and releases it after more than 40 secs…
The Capt’s sidestick is de-activated unless he presses his take over pb.
With either AP engaged, which statement is true?
Both sidesticks are locked in neutral position. By applying certain force, the lock can be overridden and the AP disengaged.
According to this indication, only the center tank pumps are feeding the engine.
True.
What does an amber line across the last two digits of the fuel quantity mean?
The fuel quantity indication in inaccurate.
After engine shutdown, what are your actions to close the fuel transfer valves?
No action is required. The valves will close automatically during the next refueling.
The message OUTER TK FUEL XFRD appears in the MEMO. What does it mean?
Fuel is transferred from the outer tank to the inner tank.
Why do the center tank pumps switch off automatically when the slats are extended for take-off?
To ensure the wing tanks are used for take-off.
You have started engine 2 during pushback, but the PTU has not operated to pressurize the GREEN hydraulic system. Why not?
The PTU will not operate until the second engine has been started.
How is the RAT deployed to power the BLUE system?

According to these indications, which source is supplying the bleed air?
The engines are running, the APU is supplying bleed air.
The APU is now switched off. Why do you still have the APU AVAIL indications?
