EIS ARCHITECTURE (1)EFIS-ECAM

The Electronic Instrument System (EIS) is shown on 6 identical CathodeRay Tubes (CRTs). The Electronic Flight Instrument System (EFIS) aredisplayed on identical Display Units (DUs) and controlled through theEFIS control panels and the lighting/loudspeaker control panels. TheElectronic Centralized Aircraft Monitoring (ECAM) pages are displayedon identical DUs and controlled through the ECAM Control Panel (ECP).DMC

The Display Management Computers (DMCs) process data in order togenerate codes and graphic instructions related to the image to display.Note the particular role of DMC 3 is to be switched instead of DMC 1or DMC 2. Each DMC can process three displays: Primary Flight Display(PFD), Navigation Display (ND) and upper or lower ECAM display.FWC

The Flight Warning Computers (FWCs) monitor the aircraft systems.These computers are the heart of the ECAM system. Each FWC generatesall warning messages to display and supplies the attention getters. It alsocomputes the flight phases and supplies aural warnings.

SDAC

The System Data Acquisition Concentrators (SDACs) receive varioussignals from the aircraft systems and send them to the FWCs and DMCs.The SDACs acquire most of the signals used to display system pages andused by the FWCs to generate amber warnings.

INPUTS

The inputs received by the FWC are used to elaborate red warnings.Various items of information for systems like engines, fuel, navigation

and which are not related to warning, are directly sent to the DMCs. Theinputs received by the SDACs are used to elaborate amber warnings.These signals will then be sent to the FWC to generate warnings.

ENGINE/WARNING DISPLAY PRESENTATION (1)GENERAL OVERVIEW

The Engine/Warning Display (EWD) is normally on the upper ElectronicCentralized Aircraft Monitoring (ECAM) Display Unit (DU). It is dividedinto two areas: the upper area and the lower area.The upper area displays:- engine primary parameters,- Fuel On Board (FOB),- slats and flaps position.The lower area is used for:- warning and caution messages,- memo messages.

ENGINE/WARNING DISPLAY PRESENTATION (1)ENGINE/WARNING DISPLAY AREAS

UPPER AREAThe symbols of the upper area are permanently displayed. Theparameters are provided in the form of analog and/or digital indications(refer to related chapter for detailed description).LEFT MEMO AREATakeoff (TO) or landing memo, normal memo, independent failuremessages, or primary failure messages and actions to do are displayedin the left memo area. As soon as a failure is detected, the memomessages are replaced by warning/caution messages.

RIGHT MEMO AREANormal memo and secondary failure messages are displayed in theright memo area. For example when an ENGine ANTI ICE P/B is setto ON, ENG A.ICE appears on the right memo area. During TO andlanding, most of the warnings are inhibited to avoid distraction of thecrew. For example, at TO, when the second engine is set to TO powerand until the aircraft has reached 1.500 ft, TO INHIB is displayed.

ENGINE/WARNING DISPLAY PRESENTATION (1)ADVISORY AND STATUS INDICATION

Advisory and status indications are "attention getters" on the display.

ADVISORY INDICATIONADV: Advisory white message appears only in single displayconfiguration. It flashes on the lower memo area to signal to the pilotthat a parameter drifts from its normal value. As the correspondingsystem page cannot be displayed on the lower ECAM DU, the pilothas to fetch the information on the ECAM Control Panel (ECP): theassociated key flashes to indicate which system is concerned.

NOTE: In normal display configuration (dual display), the relevantsystem page is automatically displayed on System Display(SD), so the ADV indication doesn't appears on the EWD.

ECAM ADVISORY & FAILURE RELATED MODES (3)ALERT CLASSIFICATION

GENERALThe alerts are classified in three levels. They depend on the importanceand urgency of the corrective actions required.- level 3: warnings (highest priority),- level 2: cautions,- level 1: cautions,- status messages.At each level, the alert messages are also classified by priority order.

LEVEL 3Level 3 agrees with an emergency configuration. Corrective orpalliative action must be taken by the crew immediately.These warnings are associated with:- Continuous Repetitive Chime (CRC) or specific sound,- warning messages on Cathode Ray Tube (CRT),- MASTER WARNing light flashing red.Typical level 3 warnings are:- aircraft in dangerous configuration or limit flight conditions (Stall,overspeed),- system failure altering flight safety (Engine fire, excess cabinaltitude),- serious system failure (Dual hydraulic failure).LEVEL 2Level 2 agrees with an abnormal configuration. Immediate crewawareness is required, but not immediate corrective action. The crewmust decide when to take the corrective action.These warnings are associated with:- Single Chime (SC),- MASTER CAUTion light amber,- warning messages on CRT.

The level 2 system failure has no direct consequence on flight safety.

LEVEL 1Level 1 agrees with a configuration requiring crew monitoring, mainlyfailures leading to a loss of redundancy or degradation of a system.The attention getters (lights and sounds) are not activated by a level1 alert.

STATUSSome defects which do not trigger warnings or cautions, but whichrequire further maintenance actions, will be indicated to the crew bymeans of a status indication, pulsing after engine shutdown. It isnecessary to call the status page manually to see the title of the affectedsystem.

ECAM ADVISORY & FAILURE RELATED MODES (3)TYPE OF FAILURE

GENERALThe failures may be of three different types, independently of theirclassification.There are 3 separate types of warnings or cautions:- those associated with an independent failure,- those associated with a primary failure,- those associated with a secondary failure.

INDEPENDANT FAILUREAn independent failure is a failure, which affects an isolated item ofequipment or system without affecting another one.Example: Flight Warning Computer (FWC) 1 failure.

NOTE: An independent failure is displayed with the title underlined.

PRIMARY FAILUREA primary failure is a failure of an item of equipment or systemcausing the loss of other equipment.Example: Green hydraulic system failure may lead to the loss of apair of spoilers.

NOTE: A primary failure is displayed with a box around the failure.

SECONDARY FAILUREA secondary failure is a loss of an item of equipment or systemresulting from a primary failure.Example: Loss of a pair of spoilers after a hydraulic system failure.The titles of the system pages corresponding to the secondary failuresare indicated on the lower right part of the Engine/Warning Display(EWD) by an asterisk.

NOTE: This part can be used if necessary to display heading titlesof warnings if the left part of the EWD is full.

ECAM ADVISORY & FAILURE RELATED MODES (3)ADVISORY

ADVISORY MODE IN NORMAL DUAL DISPLAYThe value of some critical system parameters is monitored by anadvisory mode. In Electronic Centralized Aircraft Monitoring (ECAM)normal display, when a value drifts from its normal range, thecorresponding system page is displayed automatically in order toattract crew attention well before reaching the warning or cautionlevel. The affected parameter and the system page title pulse. Thecorresponding key light on the ECAM Control Panel (ECP) is on.Example: The CAB PRESS page will be displayed if the cabin altitudeincreases above its normal value, but is still well below the thresholdof the warning. In this case the crew may revert to manual pressurecontrol and prevent warning activation.

NOTE: An advisory may or may not lead to a failure. They aretotally independent one from the other.

ECAM WARNINGS PRESENTATION (1)ECAM DISPLAY WITH AIRCRAFT SYSTEM FAILURE

In case of aircraft system failure, an aural warning, the Single Chime(SC), a visual warning and the MASTER CAUTion, attract your attention.The Engine/Warning Display (EWD) indicates the title of the failure andthe actions to take. On the status and System Display (SD), the hydraulicpage is called automatically. The CLeaR P/Bs come on and as long asthe failure is not cleared, they stay on. On the hydraulic panel the FAULTlights come on, indicating the P/Bs to release out.

NOTE: In this module, parameters are given for a CFM engine. For anIAE engine, the parameters will be shown as follows: EnginePressure Ratio (EPR), EGT, N1 and N2). The graphics showan example of sequence of Electronic Centralized AircraftMonitoring (ECAM) displays in case of green hydraulic systemfault. This may be different to your aircraft configuration.

AllElectronic Flight Instrument System (EFIS) and ECAM images are lost.One pilot must place the Electronic Instrument System (EIS) DMCselector switch to the position CAPT 3, or F/O 3 to have his PrimaryFlight Display (PFD), Navigation Display (ND) and either upper or lowerECAM images driven by the DMC 3. In the position CAPT 3, a diagonalline is displayed on lower ECAM Display Unit (DU) and F/O EFIS. Inthe position F/O 3, a diagonal line is displayed on upper ECAM DU and

CAPT EFIS. The lower ECAM DU displays the Engine/Warning Display(EWD) images (possibility to display a system or status imagetemporarily). The ECAM is in mono display.DMC 1(2)+3 FAULTIn case of DMC1 and DMC3 fault, the aural warning sounds and theMASTER CAUT comes on. The captain PFD and ND data, and theECAM System Display (SD) data lost. The ECAM is in mono display.

NOTE: If DMC 2+3 fail, the F/O EFIS and ECAM SD data is lost.

DMC 1(2) FAULTIf the DMC1 (or DMC2) fails, the aural warning sounds and the MASTERCAUT comes on. The captain (or first officer) PFD and ND data, andthe ECAM SD data are lost. The captain has to transfer to DMC 3 torecover the three DUs.

DMC 3 FAULT

When the DMC3 fails, the aural warning sounds and the MASTER CAUTcomes on. There is no change on the six DUs but a single warningmessage is displayed on the EWD to indicate this DMC 3 fault.

EIS ARCHITECTURE (1)EFIS-ECAM

The Electronic Instrument System (EIS) is shown on 6 identical LiquidCrystal Display (LCD) units and controlled through the EIS controlpanels. The Electronic Centralized Aircraft Monitoring (ECAM) displaysare identical and controlled through the ECAM Control Panel (ECP).The Electronic Flight Instrument System (EFIS) displays are controlledby the EFIS control panels and the lighting/loudspeaker control panels.

DMC

The Display Management Computers (DMCs) are data concentrator andreceive data from aircraft sensors and systems. They send them to theDisplay Units (DUs). The DUs compute and display the images on eachunit. In normal operation DMC1 drives the CAPT Primary Flight Display(PFD), the CAPT Navigation Display (ND), Engine/Warning Display(EWD) and System Display (SD). In normal operation DMC 2 drivesthe F/O PFD and ND DUs. If DMC 1 fails, it is automatically replacedby DMC 2 for ECAM only. DMC 2 cannot drive the CAPT PFD andND; a manual switching to DMC 3 is required. DMC 3 can drive any ofthe six DUs. DMC 3 is a hot spare awaiting the failure of DMC 1 or 2and can be switched to drive the DUs linked to the failed DMC.

FWC

The Flight Warning Computers (FWCs) monitor the aircraft systems.Each FWC generates all warning and caution messages, supplies theattention getters, computes the flight phase and provides aural warnings.

SDAC

The System Data Acquisition Concentrators (SDACs) receive varioussignals from the aircraft systems and send them to the FWCs and to theDMCs.

INPUTS

The inputs received by the FWC are used to elaborate red warnings.Various items of information for systems like engines, fuel, navigationand which do not agree with a warning, are directly sent to the DMCs.The inputs received by the SDACs are used by the DMCs to displaysystem pages and by the FWCs to generate amber warnings.

ECAM ADVISORY & FAILURE RELATED MODES (3)ALERT CLASSIFICATION

GENERALThe alerts are classified in three levels. They depend on the importanceand urgency of the corrective actions required.- level 3: warnings (highest priority)- level 2: cautions- level 1: cautions- status messagesAt each level, the alert messages are also classified by priority order.

LEVEL 3Level 3 corresponds to an emergency configuration. Corrective orpalliative action must be taken by the crew immediately.These warnings are associated with:- Continuous Repetitive Chime (CRC) or specific sound,- warning messages on Liquid Crystal Display (LCD),- MASTER WARNing light flashing red.Typical level 3 warnings are:- aircraft in dangerous configuration or limit flight conditions (Stall,overspeed),- system failure altering flight safety (Engine fire, excess cabinaltitude),- serious system failure (Dual hydraulic failure).LEVEL 2Level 2 agrees with an abnormal configuration. Immediate crewawareness is required, but not immediate corrective action. The crewmust decide when to take the corrective action.These warnings are associated with:- Single Chime (SC),- MASTER CAUTion light amber,- warning messages on LCD.

The level 2 system failure has no direct consequence on flight safety.

LEVEL 1Level 1 agrees with a configuration requiring crew monitoring, mainlyfailures leading to a loss of redundancy or degradation of a system.The attention getters (lights and sounds) are not activated by a level1 alert.

STATUSSome defects which do not trigger warnings or cautions, but whichrequire further maintenance actions, will be indicated to the crew bymeans of a status indication, pulsing after engine shutdown. It isnecessary to call the status page manually to see the title of the affectedsystem.

ECAM ADVISORY & FAILURE RELATED MODES (3)TYPE OF FAILURE

GENERALThe failures may be of three different types, independently of theirclassification.There are 3 separate types of warnings or cautions:- those associated with an independent failure,- those associated with a primary failure,- those associated with a secondary failure.

INDEPENDANT FAILUREAn independent failure is a failure, which affects an isolated item ofequipment or system without affecting another one.Example: Flight Warning Computer (FWC) 1 failure.

NOTE: An independent failure is displayed with the title underlined.

PRIMARY FAILUREA primary failure is a failure of an item of equipment or systemcausing the loss of other equipment.Example: Green hydraulic system failure may lead to the loss of apair of spoilers.

NOTE: A primary failure is displayed with a box around the failure.

SECONDARY FAILUREA secondary failure is a loss of an item of equipment or systemresulting from a primary failure.Example: Loss of a pair of spoilers after a hydraulic system failure.The titles of the system pages corresponding to the secondary failuresare indicated on the lower right part of the Engine/Warning Display(EWD) by an asterisk.

NOTE: This part can be used if necessary to display heading titlesof warnings if the left part of the EWD is full.

ECAM ADVISORY & FAILURE RELATED MODES (3)ADVISORY

ADVISORY MODE IN NORMAL DUAL DISPLAYThe value of some critical system parameters is monitored by anadvisory mode. In Electronic Centralized Aircraft Monitoring (ECAM)normal display, when a value drifts from its normal range, thecorresponding system page is displayed automatically in order toattract crew attention well before reaching the warning or cautionlevel. The affected parameter and the system page title pulse. Thecorresponding key light on the ECAM Control Panel (ECP) is on.Example: The CAB PRESS page will be displayed if the cabin altitudeincreases above its normal value, but is still well below the thresholdof the warning. In this case the crew may revert to manual pressurecontrol and prevent warning activation.

NOTE: An advisory may or may not lead to a failure. They aretotally independent one from the other.

DMC 1(2) FAULTIf the DMC1 (or DMC2) fails, the aural warning sounds and the MASTERCAUT comes on. The CAPT EFIS data are lost. The message "INVALIDDATA" is displayed on the CAPT EFIS and a single warning messageis activated on the EWD. DMC2 takes over automatically for ECAMimages. The CAPT (or F/O) has to transfer to DMC3 to recover the twoEFIS Display Units (DUs).DMC 3 FAULT

When DMC3 fails, the aural warning sounds and the MASTER CAUTcomes on. There is no change on the six DUs but a single warningmessage is displayed on the EWD to indicate this DMC 3 fault.

OPERATING LIMITATIONS

TESTTo test the clock, the annunciator light switch must be set to TEST.Then all the displays should show eight.

UTC AND DATEWhen the clock is in normal configuration it displays the time. Thedate is displayed by pressing the SET turn and P/B when the time ofthe day is displayed. By pressing the SET turn and P/B once more thetime of the day will be displayed again.

UTC SETTINGThe setting of the Universal Time coordinated (UTC) is done withthe UTC selector. When the selector is in SET position, the seconddigits are blanked, the minute digits flash and the hour digits arefrozen. By rotating the SET button clockwise the minutes increase,anticlockwise the minutes decrease. By pushing the SET button thehours flash, the minutes are frozen and the seconds are blanked. Byturning the SET button, hours can be adjusted. When the UTC selectoris moved from SET to INT the clock starts running from the adjustedtime with the second digits at 00. When the UTC selector is in GlobalPositioning System (GPS) position, the clock is synchronized on theGPS time, if a GPS signal is present.

DATE SETTINGThe setting of the date is done with the UTC selector. By pressing theSET button, the date is displayed. By setting the UTC selector in SETposition, the year digits flash and the month and day digits are frozen.By turning the SET button clockwise or anticlockwise, years can bemodified to obtain the chosen value. By pushing the SET button, themonths and days can be adjusted in the same way.

CHRONOMETERA first press on the CHRonometer P/B starts the chronometer, a secondpress stops it and freezes the display, and a press on the ReSeT P/Bresets it.

ELAPSED TIMETo activate the Elapsed Time (ET) function, the ET selector must beset to RUN. When set to STP, the ET counter stops, and the displayis frozen. To reset the display, the selector must be set to RST (springloaded position) and it returns to STP.FAILUREWith a clock failure or a loss of power supply, the digital displays areno longer available. With a loss of main electrical power supply, thetime is still counted in memory through the A/C battery supply, exceptfor the CHR and ET functions.

ELECTRICAL CLOCK D/O (2)SEXTANT CLOCK


UTC AND DATEThe center window (UTC) indicates the current time: hours andminutes. Periods of 15 seconds are indicated by three horizontalsegments.The current date (month, day and year) is displayed when the SETknob is pressed. To keep the date displayed, the SET P/B must beheld pressed in. To recover the time, the SET P/B must be released.

UTC AND DATE SETTINGAn UTC selector allows date and time updating:- MO: to set months and years- DY: to set day- HR: to set hours- MIN: to set minutes- RUN: to start the UTC counterThe UTC selector must be pressed and turned to set it from RUN toMINute position. When a function is selected with the UTC selector(except RUN), you can set it with the SET P/B. When pushed, theSET P/B decreases the displays. By turning it to either side, it increasesthe displays. After setting, the selector must be set back to RUN(pushed and turned).CHRONOMETERAn upper window, called CHR indicates the minutes provided theCHR P/B has been pressed. The seconds are indicated by a sweephand. Pressing the CHR P/B activates the chronometer, pressing it

again will stop it. The chronometer is reset by pressing the CHR P/Ba third time.

ELAPSED TIMETo activate the ET function, the ET selector must be set to RUN.When set to STOP, the ET counter stops. To reset the display, theselector must be set to RST (spring loaded position) and it returns toSTOP.

FAILUREWith a clock failure or a loss of power supply, the digital displays areno longer available. With a loss of main electrical power supply, thetime (UTC and ET) is still counted in memory through the clockbuilt-in-battery, except for the chronometer function.When power is restored:- the chronometer pointer returns to zero if previously displaced,- the UTC and ET indications reappear, indicating current value.

CFDS FAULT PROCESSING (3)BITE

Most aircraft system computers are equipped with a Built-In TestEquipment (BITE). The BITE, which is an electronic device (hard + soft),monitors permanently the system operation. When a failure is detected,it is stored in the BITE memory and is transmitted to the CentralizedFault Display Interface Unit (CFDIU). Memorization of the 64 previouslegs report is done by most of the BITEs.

MEMORIZATION

Memorization of failures is different when the aircraft is on ground or inflight. The full BITE functions and memorization operate in flight.On ground, the memorization is done only in the BITEs. The BITEs areprovided with flight and ground memory zones.

CFDIU

The CFDIU centralizes all information concerning aircraft system failures.Reading or printing of all the failure information is done in the cockpit.The Centralized Fault Display System (CFDS = CFDIU + BITEs)functions are accessed through the MCDUs.

CFDS MODES

Two CFDS modes are available: NORMAL and MENU modes. TheMENU MODE is available only on ground.

NORMAL MODEIn this mode, the CFDIU scans all the connected system outputs andmemorizes the failure messages in order to generate the CURRENT(LAST) LEG REPORT and the CURRENT (LAST) LEG ECAMREPORT. In flight the CFDS always operates in the normal mode.

MENU MODEIn this mode, the CFDIU dialogues with one computer at a time inorder to read the contents of its BITE memory and to initiate varioustests. This mode can only be selected on ground and interrupts thenormal mode of operation.

CFDS FAULT PROCESSING (3)REPORTS

LAST/CURRENT LEG REPORTA CURRENT LEG REPORT is elaborated during the flight. Afterthe flight, its title becomes LAST LEG REPORT. The purpose of thisitem is to present the failure messages, concerning all systems,occurred during the last/current flight. Each message contains the testof the failure, the ATA reference and the flight phase and time atwhich the failure occurred. A function correlates the "SOURCE"failure message with the "resulting" failure messages.SOURCE: Name of system affected by a failure.IDENTIFIER: Name of system affected by an external failure, whichis correlated with the "SOURCE" failure.The CFDIU capacity for failure messages memorization is up to 40lines.

LAST/CURRENT LEG ECAM REPORTA CURRENT LEG ECAM REPORT is elaborated during the flight.After the flight, its title becomes LAST LEG ECAM REPORT. Thepurpose of this item is to present the warning messages displayed onthe upper ECAM display unit during the last/current flight. These areprimary or independent warnings. Each message contains the ECAMwarning, the ATA reference and the flight phase and time at whichthe warning was triggered. When several identical and consecutivewarnings are transmitted, the CFDIU memorizes the first occurrenceonly and carries on counting with a maximum of 8. The occurrencecounter is displayed between brackets at the end of the message. TheCFDIU capacity for warning messages memorization is up to 40 lines.

POST FLIGHT REPORTThe Post Flight Report (PFR) is the sum of the LAST LEG REPORTand of the LAST LEG ECAM REPORT. The PFR can only be printedon ground. The list of ECAM WARNING MESSAGES and FAULT

MESSAGES with the associated time, flight phase and ATA referenceallow the maintenance crew to make a correlation for easiertrouble-shooting.Beginning of PFR recording:- if flight number inserted prior to first engine start, first engine start+ 3 minutes.- if not, aircraft speed > 80 knots.End of PFR recording:Aircraft speed < 80 knots + 30 seconds.

CFDS FAULT PROCESSING (3)INTERNAL/EXTERNAL FAILURES

Each BITE can make the difference between an internal and an externalfailure. Let us suppose that an Angle-Of-Attack (AOA) sensor failurehas been detected and that systems A, B and C are affected by this failure.The Air Data System (ADS) will transmit an internal failure while systemsA, B and C will transmit an external failure.

FAILURE GRAVITY

The failures are classified according to their importance:- class 1 failures are the most serious ones and require an immediatemaintenance action subject to the Minimum Equipment List (MEL).- class 2 failures may have consequences if a second failure occurs. Aclass 2 failure must be repaired within 10 days.- class 3 failures can be left uncorrected until the next
