IRS ECAM Flashcards
What would you do if you saw DMC 1, 2, or 3 fail?
In normal operation, each DMC drives the following Display Units :
DMC 1 drives the CAPT PFD, CAPT ND and the ECAM DUs.
DMC 2 drives the F/O PFD and F/O ND.
DMC 3 is on standby, ready to drive any DU.
If DMC 1 or 2 fails (the “INVALID DATA” message is displayed on the DUs), the crew manually selects the DMC 3 source (“CAPT 3” or “F/O 3”).
If DMC 1 fails (or DMC 3, if “CAPT 3” was selected), DMC 2 automatically drives the ECAM.
What happens if the upper ECAM fails?
If the upper ECAM display fails, or is switched off :
The engine/warning page automatically replaces the system/status page on the lower ECAM DU.
The flight crew can display the system/status page by :
Using the “ECAM/ND XFR“ switch, on the SWITCHING panel, to move it to a Navigation Display Unit (NDU), or
Pushing and holding (for a maximum of 3 min) the related system page pushbutton, on the ECAM control panel, to temporarily display it on the lower ECAM DU (instead of the engine/warning page).
What should you do if both ECAM screens fail?
If both ECAM displays fail, the flight crew may :
Use the “ECAM/ND XFR”, on the SWITCHING panel, to display the engine/warning page on a navigation display and, if needed,
Push and hold (for a maximum of 3 min) the related system page pushbutton, on the ECAM control panel, to temporarily display the system/status page on an ND.
What should you do if the lower ECAM fails?
If the lower ECAM display fails, or is switched off, the flight crew can display the system/status page by :
Using the “ECAM/ND XFR” switch, on the SWITCHING panel, to display it on the NDU, or
Pushing and holding (for a maximum of 3 min) the related system page pushbutton, on the ECAM control panel, to temporarily display it on the upper ECAM DU (instead of the engine/warning page).
What happens if the CM1s Left EFIS (electronic flight instrument screen) fails? How can the ND be displayed?
The Electronic Instrument System (EIS) presents data on six identical Display Units (DUs):
The Electronic Flight Instrument System (EFIS) displays mostly flight parameters and navigation data on the Primary Flight Displays (PFDs) and Navigation Displays (NDs).
If a PFDU fails, the system automatically transfers the PFD image to the NDU.
The pilot can also make this transfer manually by :
turning the PFD ON-OFF/brightness control OFF, or
pressing the PFD/ND/XFR pushbutton, which cross-changes the images between the PFDU and the NDU.
If an NDU fails, the pilot can use the PFD/ND/XFR pushbutton to transfer the ND image to the PFDU.
What happens when an ADVISORY is triggered?
Automatic call of the relevant system page on the S/D.
The affected parameter pulses green.
What indications follow a level 1 caution?
Amber caution : Requires crew monitoring :
Failures leading to a loss of redundancy or system degradation (eg : FCDC fault)
Caution message (amber) on E/WD generally without procedure.
What indications follow a level 2 caution?
Amber caution :
The flight crew should be aware of the configuration or failure, but does not need to take any immediate action. However, time and situation permitting, these cautions should be considered without delay to prevent any further degradation of the affected system :
System failure without any direct consequence on the flight safety (eg: HYD G SYS LO PR)
MASTER CAUT light amber steady
Caution message (amber) on E/WD
Automatic call of the relevant system page on the S/D
What indications follow a level 3 caution?
Red warning : The configuration, or failure requires immediate action :
Aircraft in dangerous configuration, or limit flight conditions (eg: stall, o/speed)
System failure altering flight safety (eg : Eng fire, excess cab alt)
Continuous Repetitive Chime (CRC) or specific sound or synthetic voice
MASTER WARN light red flashing or specific red light
Warning message (red) on E/WD
Automatic call of the relevant system page on the S/D
What is meant by Independent, Primary, or Secondary Failures?
Independent :
a failure that affects an isolated system or item of equipment without degrading the performance of others in the aircraft.
Primary :
a failure of a system or an item of equipment that costs the aircraft the use of other systems or items of equipment.
Secondary :
the loss of a system or an item of equipment resulting from a primary failure
What is signified by a downward pointing arrow at the bottom of the EWD or STS S.D.?
The arrow appears if the data on the STATUS page overflows the left or right area of the page.
The flight crew can press the CLR pb, in order to scroll the display to view the overflow.
Note:
The titles of the different parts of the display appear in white and underlined.
What is the meaning of T/O or LAND INHIBIT (magenta memo)?
When are they Displayed?
During the takeoff and landing phases, the right side of the memo area displays specific TO INHIBIT or LDG INHIBIT (magenta) memos.
Takeoff and landing memos are displayed, as follows, during the related flight phases:
When does the Landing memo appear on the EWD (Engine/ Warning Display)?
Below 2000 ft to touchdown (80kts)
When does the TO memo appear on the EWD (Engine/ Warning Display)?
2 mins after Engine 2 start or when the TO config button is pressed.
If one ECAM fails, how is an ADV shown?
If an advisory is triggered, when the ECAM is in the single-display configuration, an advisory message appears on the upper part of the E/WD, and the associated key on the ECAM control panel flashes to identify the appropriate system page.
