Indicating and Recording Systems
How can the EFIS displays be controlled after an EFIS control panel failure?
Through the related CDU (CDU on same side).
Does this operation require a failure of the EFIS control panel?
No (can control EFIS display through CDU at all times).
How does EFIS control from a CDU affect the normal panel operation?
It inhibits inputs FM the respective EFIS control panel.
How is the display on the lower centre blanked?
By selecting a second selection of a display already on the lower centre display.
How many CDUs can be used for DSP control at a time?
1
When is selection of an inboard MFD no longer available?
When PFD is selected to the inboard MFD (other displays selected FM DSP are inhibited).
Which synoptic displays can be compacted if EICAS is on an inboard MFD?
ENG, AIR and FUEL.
What affect does the failure of the upper centre display have?
Switches EICAS display to lower centre display.
When are the DSPL CTRL switch to be used?
When automatic switching fails (DSPL CTRL switch provide capability to manually select PFD and ND sources).
Which pilot control the cursor on the lower display?
The last pilot who selected the cursor on the lower display
What is the implication of STATUS messages?
Dispatch capability may be affected (all EICAS status messages are listed in the DDG and provide a cross reference to the MEL for dispatch capability)
When does a rectangular icon precede an EICAS message?
[] prefaces EICAS alert messages that have procedural steps and alert messages for CXlists that have notes or information of which the crew must be made aware.
When can red EICAS messages ever be cancelled?
Never (cannot be cancelled by pushing the CANC/RCL switch).
Can COMM messages be cancelled?
No (cannot be cancelled by pushing the CANC/RCL switch).
Where are EICAS MEMO messages displayed?
In white at the bottom of the last page of EICAS alert messages on the primary EICAS display.
How are EICAS messages prioritised?
WARNING CAUTION ADVISORY Communications Memo Status Cue
What does the aural WAILER indicate?
Autopilot disconnect.
How is an impending STALL indicated?
L & R stick shakers (independently vibrate L & R control columns).
When are takeoff configuration warnings inhibited during takeoff?
If thrust decreased BLW T/O range and airspeed < V1, or, V1 or rotation whichever is first.
How long will a takeoff configuration EICAS message be displayed for?
Message remains displayed for 10s after thrust reduced to aid in identifying the T/O configuration
When will the C chord aural be heard?
900’ prior to reaching altitude selected on the MCP.
How is the ALTITUDE ALERT EICAS message inhibited during a normal approach?
When G/S captured or LDG flaps selected and LDG gear down & locked.
What level is the PILOT RESPONSE EICAS message?
Initially an ADVISORY, after a predefined time elapses after the last switch detection was detected and no action from the pilot has been undertaken, progresses to CAUTION message, then eventually to WARNING message
What is a closed loop item?
CXlist items that involve continuous and automatic monitoring of switch/lever/selector position.
Which checklists have the ultimate priority?
CXlists associated W/ EICAS warning messages.
Why do some EICAS messages not have an icon?
Icon (white empty box to left of a message) indicates CXlist status. If icon not displayed by an EICAS message it means either: • All CXlist items complete. • No CXlist procedure for the displayed message. • Another message is displayed whose corresponding CXlist inhibits display of the icon.
What normal checklist would follow a go-‐around?
After T/O CXlist.
A closed loop item is not responding. How can the checklist be completed?
By selecting item override (allows any CXlist to be completed by selection of the line item override key [changes colour of highlighted step to cyan]).
When does the STATUS cue inhibit start?
Engine start (until 30 minutes after T/O).
List 3 types of alerts inhibited at 80 knots:
• EICAS WARNING message: CONFIG GEAR STEERING. • PWS caution alerts. • All EICAS ADVISORY messages.
When is the red ENG FAIL warning on the PFD inhibited?
• Engine start until 65kts airspeed. • New red ENG FAIL on PFD: 6kts before V1 until LDG.
How many EICAS events can be manually recorded?
Up to 5 events (by pushing the EICAS EVENT RCD switch).
