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…
Excessive differential pressure in the cabin.
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?
6000 feet
As you can see, cabin pressure control is manual. You want to descend from FL350 to FL 310. What is you target cabin alt?
5300 feet
By moving the MAN V/S CTL to this position…
The cabin altitude is raised by opening the outflow valve.
For the aircraft to be in this normal operation, open circuit configuration, what condition must be satisfied?
The aircraft must be on the ground with thrust levers not at T/O.
With both the BLOWER and EXTRACT pb sw in OVD, what happens to the ventilation system?
The system goes into intermediate configuration and the blower fan stops.
This aircraft is following a track of 140.
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?
It means the point has to be overflown.
Why is the word DECELERATE on the FMA?
The aircraft has passed the computed ideal descent point.
How can you get the mechanics attention when he is outside the aircraft?
Use the Mech pb sw on the CALLS panel which sounds an external horn.
In this example what does the white SEL light mean?
It is an indication that both RMP 1 and RMP 2 are being used to tune VHF2.
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?
By pushing the EXT PWR pb thus disconnecting the external power.
Take a look at the ECAM. Now the IDG oil temperature has cooled, the IDG can be reconnected by pressing the IDG pb.
False.
You notice the red FAULT light on the RAT & EMER GEN pushbutton. How do you interpret this indication?
The EMER GEN is not yet supplying the system.
You want to open the cabin door, whilst lifting the control handle the white light illuminates. What does this mean?
The slide is still armed.
There is no other way of deploying the overwing escape slide if it fails to deploy automatically on the opening exit.
False.
If the oxygen masks fail to deploy automatically how else can they be deployed?
They can be deployed by pressing the MASK MAN pb on the overhead panel.
Can the APU fire test be performed using battery power only?
Yes.
According to these indications…
One fire detection loop has failed. Fire detection for both engines is still available.
Which control surfaces are used for the mechanical backup?
THS and rudder.
What does the white cross indicate?
It is an indicator for the sidestick deflection during the flight control check.
In Normal Law, if one sidestick is rapidly pulled fully back, can the aircraft’s maximum allowed “G” load be exceeded?
No. The load factor limitation overrides sidestick command to avoid excessive “G” loads.
In Normal Law, what is the maximum bank angle you can reach with the sidestick fully deflected?
67 degrees
According to these indications, which flight control law is active?
Normal Law
According to these indications, which flight control law is active?
Alternate Law
According to these indications, which flight control law is active?
Direct Law
