Indicating/Recording Flashcards
Describe the organization of the Electronic Instrument System (EIS)
EFIS with 2 PFD’s, 2 ND’s
ECAM with 1 E/WD and SD
Describe the components of the Air Data Inertial Reference System (ADIRS)
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
General E/WD displays
primary engine parameters: N1 N2 EGT fuel flow
memo section: normal and non-normal, Class 1 ECAM messages
Explain the color-coding convention on the E/WD.
- Green
- White
- Blue
- Amber
- Red
- Magenta
- Amber Xs
- 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
Recall the EFIS Display Unit (DU) priority.
PFD takes priority over ND
PFD automatically transfers to inner DU
Recall the ECAM Display Unit (DU) priority.
E/WD takes priority over SD
E/WD automatically transfers to lower ECAM DU
Recall the functions of the ND Brightness Control Knob.
The Inner knob is used to control the general brightness of the ND symbols. Rotating this knob all the way counterclockwise turns off the ND.
The Outer knob controls the brightness of both: • Weather Radar displays
and
• EGPWS Terrain displays
Explain the functions of the three Display Management Computers (DMCs).
▪ 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.
Recall the types of failure messages.
Independent: failure that affects an isolated system
underlined
Primary: failure that affects other systems
boxed
Secondary: systems affected by primary failure
amber in E/WD memo section
Indications of a Display Unit (DU) failure.
▪ A failed DU will flash, go blank or be distorted.
▪ DUs are not monitored by the FWCs, so there will be no ECAM messages.
Describe the indications of pumps on the Systems Display (SD).
Pumps – presented as a square:
Inline green – green vertical line indicates the pump is on and pump pressure is normal.
Crossline green – green line indicates the pump is off in accordance with automatic logic.
Crossline amber – amber line indicates the pump has been manually selected OFF.
LO amber – indicates the pump is on, but pump pressure is low.
Describe the indications of valves on the Systems Display (SD).
Valves – presented as a circle:
Inline green – green line connecting to system indicates the valve is open.
Crossline green – green line NOT connecting to the system line indicates the valve is closed.
Crossline amber – the valve is stuck closed when it is being commanded to open.
Inline amber – the valve is stuck open when it has been commanded to close.
Diagonal amber – diagonal line indicates that the valve is in-transit.
Explain the location and function of the STATUS page.
Located on the SD (Systems Display)
- Provides an operational summary of the state of the aircraft.
▪ 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.
NOTE: The STS REMINDER (A white boxed STS) appears at the lower portion of the E/WD whenever information exists on the STATUS page.
Describe the functions of the SWITCHING panel.
▪ ATT HDG
▪ AIR DATA
▪ EIS DMC
▪ ECAM/ND XFR
▪ 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.
Describe the function of the CLR, RCL, and T.O. CONFIG pbs on the ECAM control panel.
▪ 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.
