Systems Exam Flashcards
(100 cards)
A temperature of each aircraft zone is optimized by means of a ???
A TRIM AIR valve
Under what conditions should the pack flow controller be set to LOW?
With a low passenger load to reduce 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?
HI flow is automatically selected regardless of PACK FLOW selector position because air is only 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 ft
As you can see, cabin pressure control is manual. You want to descend from FL350 to FL310. What is your target CABIN ALT?
5300 ft
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 conditions must be satisfied?
The aircraft must be on the ground with the thrust levers not at T/O
With both the BLOWER and EXTRACT pb sw in OVRD, 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 (HDG 140)
Have a look at the FMA. The functions are 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 an armed mode
True
A/THR in 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 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 this 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 RMP2 are being used to tune VHF 2
In case of RMP 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 BAT pbs are on
What is the meaning of the green AVAIL light?
External Power is plugged in, you must push the EXT PWR pb to connect it
