Indicating / Recording DSC 31 EIS ECAM Flashcards
What does ECAM stand for?
Electronic Centralised Aircraft Monitor
What does DMC stand for?
Display Management Computers
How many DMC’s obtain data from the different sensors and computers and send to the display units?
3
How many System Data Acquisition Concentrator’s (SDAC) are there?
2
What is the function of the System Data Acquisition Concentrator’s (SDAC) ?
To aquire data from sensors that monitor aircraft systems and position of system control switches, then process it and send it to the DMC’s for digital display and cautions
Where do the signals from the SDAC’s go?
To the 3 DMC’s to generate displays of system pages and engine parameters
To the 2 FWC’s to generate ECAM messages and aural alerts
What do the FWC’s generate?
Alert messages
Memo’s
Aural Alerts
Synthetic voice messages
as well as:
- Radio height callouts
- Decision height callouts
- Landing distance and landing speed increments
From where do the FWC’s aquire their data to generate:
a) red warnings?
b) amber cautions?
a) Directly from aircraft sensors, or systems
b) through the SDAC’s
What drives the Master Warning and Master Caution lights?
the FWC’s
What data do the ADIRU’s provide to the DMC’s?
Attitude
Altitude
Speed
Position
What data does Flight Management and Guidance Computers (FMGC’s) provide to the DMC’s?
Navigation information
Each DMC can simultaneously supply……?
- a PFD
- an ND
- Both ECAM E/WD and SD
In Normal operation, DMC 1 supplies….?
Captain PFD
Captain ND
both ECAM DU’s
In Normal operation, DMC 2 supplies…..?
FO PFD
FO ND
In Normal operation, DMC 3 supplies……?
DMC 3 is on standby ready to drive any DU in case of DMC 1 or 2 failure
What is the indication if DMC 1 fails?
INVALID DATA message on:
Captain PFD
Captain ND
Both ECAM DU’s
What can be done in the case of a DMC 1 failure?
Manually select CAPT 3 on the EIS DMC switching panel. DMC 3 now supplies: Captain PFD Captain ND Both ECAM DU's
What does a blank DU indicate?
Power supply failure
Which ECAM screen has priority in the case of a DU failure?
The E/WD
How can the SD be displayed on the Captain’s or FO’s ND?
Select CAPT or FO on the ECAM/ND XFR switching panel
After a failure of the upper ECAM DU how can the SD be temporarily displayed on the lower ECAM DU?
By pushing and holding the (max 3 mins) the related system page pb on the ECAM control panel.
If the lower ECAM display fails or is switched off how can the flight crew display the system status page?
- using the ECAM/ND XFR switch
- pushing and holding (max 3mins) related system page pb on the ECAM control panel
What happens if the upper ECAM display fails or is switched off?
The E/WD page automatically replaces the system/status page on the lower ECAM DU
If both ECAM DU’s fail , how can the
a) E/WD page
b) SD page
be displayed?
a) use ECAM/ND to display on the CAPT or FO ND
b) use ECAM/ND to display on the CAPT or FO ND and press and hold (max 3min) related system page pb to temporarily display on ND
