INDICATING/RECORDING SYSTEMS Flashcards
What does a white color mean on a push-button?
An abnormal pb position
What does red colors mean on a push-button?
Failure that requires immediate action
What does amber color mean on a push-button?
Failure that requires attention, but not immediate action
What does green color mean on a push-button?
Normal system operation
What does blue color mean on a push-button?
Normal system operation but it is temporary, like anti-ice etc
What does “DU” stand for?
Display Unit
What is the “DMC”, what is its function and how many do we have?
Display Management Computer
We have three DMCs
They acquire and process all the signals received from sensors and other computers to generate the images to be displayed on the PFD, ND, E/WD and SD
What does two dots indicate on a push-button?
That section of the switch is not used
What is the “FWC” and what is its function?
Flight Warning Computer
Two FWCs generate alert messages, memos, aural alerts and synthetic voice messages
What is represented by the “FPV”?
The lateral and vertical trajectory of the aircraft with respect to the ground
What does the presence or VOR 1 in red indicate?
The #1 VOR receiver is inoperative
What does a pulsating green engine parameter indicate?
An ADVISORY that the parameter is about to reach its limit
What does “ECAM” stand for?
Electronic Centralized Aircraft Monitor
What does “EIS” stand for?
Electronic Instrument System
On the SD page what does a blue color indicate?
An action that you have to perform
On the SD page what does a green color indicate?
Information
On the SD page what does a white color indicate?
System titles
On the SD page what does red and amber colors indicate?
Inoperative systems in order of severity
What two subsystems is the EIS split into?
- EFIS, that displays info on the PFD and ND
- ECAM, that displays info on the E/WD and the SD
What does SDAC stand for and what do they do?
System Data Acquisition Computer
Makes sense of the signals from the senors and sends them on to the FWC and the DMCs
How many screens can a DMC control?
4
What screens are DMC 1 controlling?
CAPT PFD, ND and E/WD + SD
What screens are DMC 2 controlling?
F/O PFD and ND
What happens if DMC 1 fails?
Invalid data msg comes up on screen.
Switching to DMC 3 takes the role of DMC 1 so the PFD, ND, E/WD and SD would be working
What happens if DMC 1 and 3 fails, will you have the E/WD and SD screens available?
Yes, but the Captains PFD and ND would be blank as one DMC can only drive 4 screens
What is generated by the FWC?
Attention getters
Callouts
Delta Vapp
From where does the FWC get information for CAUTION generation?
The SDACs
From where does the FWC get information for WARNING generation?
Directly from the sensors and not from the SDACs
What 4 systems bypasses the SDACs and the FWCs?
- LGCIU (Landing Gear Control Interface Unit) Gear up or down
- FQI Fuel (Quantity Indicator)
- FADEC
- FCDC (Flight Control Data Concentrators) Where are the controls
What do you loose if both SDACs fails?
- Parameters, except from LGCIU, FQI, FADEC and FCDC
- Some Cautions that comes directly from the sensors to the FWC
What do you loose if both FWCs fails?
No WARNINGS or CAUTIONS are generated
Also Attention Getters, Callouts and Delta Vapp are not available
What msg will you see if there is a DMC fault?
“INVALID DATA” on the screen
What msg will you see if there is a DU fault?
“INVALID DISPLAY UNIT” or “F” on the screen
When is the sideslip target blue?
- If CONFIG 1,2 or 3 is selected and
- any ENG N1 is more than 80% and
- the difference between both ENG N1 exceeds 35%
What is the result if you center the blue beta target?
When this index is centered with the roll index the sideslip target for optimum aircraft performance
What happens to the aircraft reference symbol on the PFD when TRK-FPA mode is active?
It reduces in size compared to when it is in HDG-V/S mode
When is Mach nr displayed?
Above M0.5
At what speeds (IAS and M) does the high speed protection start?
VMO +6kt or MMO +0.01
For the ECON speed range in a descent, what is the upper and lower max limits it will display?
- Max is speed target +20 kt limited to VMAX or VMO -3 or MMO -0.006 whichever is lowest
- Lowest is speed target -20 kt limited to green dot, F, S, or VLS whichever is highest
How is Vr indicated on the PFD speed tape?
A cyan dot
