What triggers a reset in the CIDS system during an error?
Power fluctuation
Simultaneous faults in both DEUs
Watchdog Timer activation
What does the Cabin Configuration Software do?
Adjust engine thrust
Stores layout and passenger service configurations
Records black box data
Why is the CIDS structured on a dual-channel architecture?
To control multiple audio zones
For data transfer speed

IFE
DEU via CIDS
PA decoder
What is the maximum number of characters displayed per row on AIP?
8
16
24
Which audio component transmits crew announcements?
IFE Decoder
PA Amplifier
Video Control Unit
How is the CIDS updated with new software or data?
Via maintenance laptop connection
Through CAM over ARINC 429
Using Data Loader and LDM port
What happens if a fault occurs in the active DEU?
System shuts down
CIDS switches to standby DEU automatically
A reset is required from cockpit
How are FAP faults categorized?
Visual and audible
System, status, and maintenance
Critical and non-critical
What component links the cabin crew interphone to the CIDS?
Cabin Assignment Module
Audio Management Unit
PSU
What is the function of the cabin lighting preset modes?
Sync lights with music
Set mood and time-based lighting scenarios
Control temperature
Why is a daisy-chain configuration used for the PSU?
For synchronized airflow
To simplify wiring and reduce weight
To increase system redundancy
What information can the CAM module be reprogrammed with?
Aircraft registration only
Video playback lists
Cabin layout, seat location, and function mapping
How are cabin attendant announcements transmitted?
Press the “press to talk” switch and talk into handset.
Press the announcement button and talk.
Talk straightly to the handset.
