18) If simultaneous failures occur, how will they be presented to the crew on the ECAM?

Answer 18

Priority for failures are level 3 first, then level 2, then level 1

Question 19

Answer 27

Three Display Management Computers (DMCs)

Question 28

DMC 3 - On standby

Question 29

29) How can you tell if a DMC has failed?

INVALID DATA displayed on Display Unit

Question 30

Automatically switches to lower ECAM

Question 31

31) If both the EWD and SD display units fail, how can you display EWD information?

Answer 31

Use the ECAM/ND XFR knob and push and hold the related system page. Then displayed on Capt or FO ND, whichever was selected.

Question 32

32) With the upper EWD displayed on the lower screen, how else can you view SD information?

Answer 32

Use the ECAM/ND XFR knob or push and hold the related system page pb and it will be displayed on lower ECAM

Question 33

33) What does pressing the ALL pb on the ECAM control panel accomplish?

Answer 33

Displays all system pages at 3 second intervals

Question 34

34) What does pressing the RCL pb on the ECAM control panel do?

Answer 34

Displays all alters previously cleared by CLR pb that are still active.
If you hold for more than 3 seconds, displays all alerts previously cleared and all alerts cancelled via EMER CANC pb.

Question 35

35) If you press the STS pb and the system has no STATUS messages, what will be displayed?

Answer 35

“NORMAL” for 3 seconds

Question 36

36) If power fails to the ECAM control panel, which buttons are still functional?

Answer 36

CLR, RCL, STS, EMER CANC & ALL pbs remain operative.

Question 37

37) What does the EMER CANC pb do when a warning exists?

Answer 37

Silences the aural warning and clears MASTER WARN but doesn’t affect the ECAM messages.
For cautions it cancels any present caution for the rest of the flight.

Question 38

38) What occurs when the T.O CONFIG pb is pressed?

Answer 38

Simulates application of TO power.

Test that triggers a warning if the aircraft is not in take off configuration.
