The E/WD automatically replaces the SD on the lower ECAM display

Question 5

If both the E/WD and SD display fail, how can you display E/WD information?

Answer 5

Select the ECAM/ND XFR switch to CAPT or FO to transfer the E/WD to either ND

-press and hold an appropriate system page button to display the information temporarily on the ND

Question 6

If the ECAM upper display knob were switched to OFF what would occur?

Answer 6

Answer 7

Press and hold the appropriate system button on the ECAM control panel you want to view

Question 8

What do you check on the SD pages during preflight?

Answer 8

DOOR page: OXY…check pressure

HYD page: Reservoir fluid level…check in normal range

ENG page: ENG oil quantity…check normal

Question 9

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

Answer 9

• the system simulates the application of T.O. power and checks certain systems for proper configuration
• a warning is displayed if a system is not configured properly
• “TO CONFIG NORMAL” is displayed in the T.O. MEMO section if the configuration is correct

Question 10

What is DMC?

Answer 10

Display Management Computers:

Three identical DMCs obtain data from various sensors and computers aboard the aircraft and send it to the DUs

Question 11

What is a SDAC? How many do we have?

Answer 11

System Data Acquisition Concentrator: 2 identical

• acquire data and generate signals, some to the DMCs to generate displays of system pages and engine parameters and;
• some to the FWCs which use them to generate ECAM messages and aural alerts

Question 12

What is FWC? How many do we have?

Answer 12

Flight Warning Computer: 2 identical computers

-generate alert messages on the E/WD and SD with data acquired from the SDACs; also generates radio and decision height callouts, Master Warning, and Master Caution

Answer 14

DC ESS Bus or HOT Bus 1

Question 15

When V/S analog pointer and digital indication will turn amber under what conditions?

Answer 15

• 6000 ft/min, climb or descent
• V/S is greater than 2000 ft/min during descent when altitude is between 1000’ and 2500’ RA
• V/S is greater than 1200 ft/min during descent when below 1000’ RA

Question 16

What is the CVR and DFDR automatic activation logic?

Answer 16

• For 5 minutes after electrical power is supplied to the aircraft, or after last engine shutdown
