Indicating/Recording

Question 1

Describe the organization of the Electronic Instrument System (EIS)

Answer 1

EFIS with 2 PFD’s, 2 ND’s

ECAM with 1 E/WD and SD

Question 2

Describe the components of the Air Data Inertial Reference System (ADIRS)

Answer 2

3 ADIRU’s consisting of
an ADR (processes pitot static information)
and an IR (processes attitude, positional and wind data)

ADIRU 1 supplies CA’s PFD and ND
ADIRU 2 supplies FO’s PFD and ND
ADIRU 3 is backup

Question 3

General E/WD displays

Answer 3

primary engine parameters: N1 N2 EGT fuel flow

memo section: normal and non-normal, Class 1 ECAM messages

Question 4

Explain the color-coding convention on the E/WD.

• Green
• White
• Blue
• Amber
• Red
• Magenta
• Amber Xs

Answer 4

• Green – normal, long-term operation.
• White – remarks and labeling guidance for procedures.
• Blue – units of measure and ECAM action steps.
• Amber - failure or configuration needing crew awareness, but not necessarily immediate action.
• Red – a failure or configuration requiring immediate crew action.
• Magenta - informational messaging.
• Amber Xs – information not available

Question 5

Recall the EFIS Display Unit (DU) priority.

Answer 5

PFD takes priority over ND

PFD automatically transfers to inner DU

Question 6

Recall the ECAM Display Unit (DU) priority.

Answer 6

E/WD takes priority over SD

E/WD automatically transfers to lower ECAM DU

Question 7

Explain the functions of the three Display Management Computers (DMCs).

Answer 7

▪ DMC 1 provides information to the CA’s PFD, ND, and the E/WD.
▪ DMC 2 provides information to the FO’s PFD, ND, and the SD.
▪ DMC 3 serves as a backup to either DMC 1 or DMC 2.

Question 8

Recall the types of failure messages.

Answer 8

Independent: failure that affects an isolated system
underlined

Primary: failure that affects other systems
boxed

Secondary: systems affected by primary failure

Question 9

Indications of a Display Unit (DU) failure.

Answer 9

▪ A failed DU will flash, go blank or be distorted.

▪ DUs are not monitored by the FWCs, so there will be no ECAM messages.

Question 10

Explain the location and function of the STATUS page.

Answer 10

▪ Displayed by:
• Pressing the STS pb on the ECAM control panel.
• Automatically as part of the ECAM Non-Normal Procedure.
• Automatically when CONF 1 (FLAPS 1) has been selected in the approach phase and the Status page is not
empty.

Question 11

Describe the functions of the SWITCHING panel.

▪ ATT HDG

▪ AIR DATA

▪ EIS DMC

▪ ECAM/ND XFR

Answer 11

▪ ATT HDG – selects IRU 3 for attitude and heading information when IRU 1 or 2 fail.

▪ AIR DATA – selects ADR 3 for pitot-static information when ADR 1 or 2 fail.

▪ EIS DMC – selects DMC 3 when DMC 1 or 2 fail.

▪ ECAM/ND XFR – transfers the SD (lower ECAM) information to the CA’s or FO’s ND screen.

Question 12

Describe the function of the CLR, RCL, and T.O. CONFIG pbs on the ECAM control panel.

Answer 12

▪ CLR pbs
▪ Used to clear failure messages and sequence through the SD pages during an ECAM non-normal procedure.
▪ With multiple failure messages displayed, pressing the CLR pb will remove (clear) the first message and all its
associated action steps.
o RCL pb
▪ Used to recall failure messages previously cleared by the CLR pbs that are still active.
▪ If there are no cleared messages, “NORMAL” appears on the E/WD memo section.
▪ If held for more than 3 seconds, the E/WD displays any CAUTION messages that were canceled by the EMER CANC
pb.
o TO CONFIG pb
▪ Used to test the Takeoff Warning system.
▪ Simulates the application of takeoff power.
▪ Generates all warnings associated with the aircraft not correctly configured for takeoff.

Question 13

Describe the effects of using the EMER CANC pb in response to ECAM WARNINGS versus CAUTIONS.

Answer 13

▪ Warnings:
• Cancels (stops) the aural warning (CRC) for as long as the failure condition continues.
• Extinguishes the MASTER WARNING lights.
• Does not affect the ECAM message display (MASTER WARNING message remains in view).
▪ Cautions:
• Extinguishes the MASTER CAUTION lights.
• Cancels (stops) the aural warning (Single chime ) for as long as the failure condition continues.
• Cancels ECAM message display for the remainder the flight (MASTER CAUTION message is removed).
• Canceled MASTER CAUTION messages may be recalled (restored) by pressing the RCL pb for 3 seconds.
NOTE 1: The EMER CANC pb should only be used to suppress spurious MASTER CAUTIONS.
NOTE 2: The EMER CANC pb is not to be used in place of a CLR pb when performing an ECAM Non-Normal
Procedure. Used for cancelling nuisance cautions and warnings (i.e. intermittent or random
messages previously addressed or MEL’d.)
