  4. 4. SINGLE AISLE TECHNICAL TRAINING MANUAL EIS ARCHITECTURE (1) and which are not related to warning, are directly sent to the DMCs. The EFIS-ECAM inputs received by the SDACs are used to elaborate amber warnings. These signals will then be sent to the FWC to generate warnings. The Electronic Instrument System (EIS) is shown on 6 identical Cathode Ray Tubes (CRTs). The Electronic Flight Instrument System (EFIS) are displayed on identical Display Units (DUs) and controlled through the EFIS control panels and the lighting/loudspeaker control panels. The Electronic Centralized Aircraft Monitoring (ECAM) pages are displayed on identical DUs and controlled through the ECAM Control Panel (ECP). DMC The Display Management Computers (DMCs) process data in order to generate codes and graphic instructions related to the image to display. Note the particular role of DMC 3 is to be switched instead of DMC 1 or 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 generates all warning messages to display and supplies the attention getters. It also computes the flight phases and supplies aural warnings.U3T06191 - U0M35M0 - UM31P2000000002 SDAC The System Data Acquisition Concentrators (SDACs) receive various signals from the aircraft systems and send them to the FWCs and DMCs. The SDACs acquire most of the signals used to display system pages and used 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 MAINTENANCE COURSE - M35 LINE MECHANICS EIS ARCHITECTURE (1) May 10, 2006 (CFM56-5B/ME)  Page 2 31 - INDICATING/RECORDING SYSTEMS

  6. 6. SINGLE AISLE TECHNICAL TRAINING MANUAL ENGINE/WARNING DISPLAY PRESENTATION (1) GENERAL OVERVIEW The Engine/Warning Display (EWD) is normally on the upper Electronic Centralized Aircraft Monitoring (ECAM) Display Unit (DU). It is divided into 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.U3T06191 - U0M35M0 - UM31P4000000003 MAINTENANCE COURSE - M35 LINE MECHANICS ENGINE/WARNING DISPLAY PRESENTATION (1) May 10, 2006 (CFM56-5B/ME)  Page 4 31 - INDICATING/RECORDING SYSTEMS

  8. 8. SINGLE AISLE TECHNICAL TRAINING MANUAL ENGINE/WARNING DISPLAY PRESENTATION (1) ENGINE/WARNING DISPLAY AREAS UPPER AREA The symbols of the upper area are permanently displayed. The parameters are provided in the form of analog and/or digital indications (refer to related chapter for detailed description). LEFT MEMO AREA Takeoff (TO) or landing memo, normal memo, independent failure messages, or primary failure messages and actions to do are displayed in the left memo area. As soon as a failure is detected, the memo messages are replaced by warning/caution messages. RIGHT MEMO AREA Normal memo and secondary failure messages are displayed in the right memo area. For example when an ENGine ANTI ICE P/B is set to ON, ENG A.ICE appears on the right memo area. During TO and landing, most of the warnings are inhibited to avoid distraction of the crew. For example, at TO, when the second engine is set to TO power and until the aircraft has reached 1.500 ft, TO INHIB is displayed.U3T06191 - U0M35M0 - UM31P4000000003 MAINTENANCE COURSE - M35 LINE MECHANICS ENGINE/WARNING DISPLAY PRESENTATION (1) May 10, 2006 (CFM56-5B/ME)  Page 6 31 - INDICATING/RECORDING SYSTEMS

  10. 10. SINGLE AISLE TECHNICAL TRAINING MANUAL ENGINE/WARNING DISPLAY PRESENTATION (1) ADVISORY AND STATUS INDICATION Advisory and status indications are "attention getters" on the display. ADVISORY INDICATION ADV: Advisory white message appears only in single display configuration. It flashes on the lower memo area to signal to the pilot that a parameter drifts from its normal value. As the corresponding system page cannot be displayed on the lower ECAM DU, the pilot has to fetch the information on the ECAM Control Panel (ECP): the associated key flashes to indicate which system is concerned. NOTE: In normal display configuration (dual display), the relevant system page is automatically displayed on System Display (SD), so the ADV indication doesnt appears on the EWD.U3T06191 - U0M35M0 - UM31P4000000003 MAINTENANCE COURSE - M35 LINE MECHANICS ENGINE/WARNING DISPLAY PRESENTATION (1) May 10, 2006 (CFM56-5B/ME)  Page 8 31 - INDICATING/RECORDING SYSTEMS

  14. 14. SINGLE AISLE TECHNICAL TRAINING MANUAL ECAM ADVISORY & FAILURE RELATED MODES (3) The level 2 system failure has no direct consequence on flight safety. ALERT CLASSIFICATION LEVEL 1 GENERAL Level 1 agrees with a configuration requiring crew monitoring, mainly The alerts are classified in three levels. They depend on the importance failures leading to a loss of redundancy or degradation of a system. and urgency of the corrective actions required. The attention getters (lights and sounds) are not activated by a level - level 3: warnings (highest priority), 1 alert. - level 2: cautions, STATUS - level 1: cautions, - status messages. Some defects which do not trigger warnings or cautions, but which At each level, the alert messages are also classified by priority order. require further maintenance actions, will be indicated to the crew by means of a status indication, pulsing after engine shutdown. It is LEVEL 3 necessary to call the status page manually to see the title of the affected Level 3 agrees with an emergency configuration. Corrective or system. palliative 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 cabinU3T06191 - U0M35M0 - UM31D3000000001 altitude), - serious system failure (Dual hydraulic failure). LEVEL 2 Level 2 agrees with an abnormal configuration. Immediate crew awareness is required, but not immediate corrective action. The crew must decide when to take the corrective action. These warnings are associated with: - Single Chime (SC), - MASTER CAUTion light amber, - warning messages on CRT.

  16. 16. SINGLE AISLE TECHNICAL TRAINING MANUAL ECAM ADVISORY & FAILURE RELATED MODES (3) TYPE OF FAILURE NOTE: This part can be used if necessary to display heading titles of warnings if the left part of the EWD is full. GENERAL The failures may be of three different types, independently of their classification. 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 FAILURE An independent failure is a failure, which affects an isolated item of equipment or system without affecting another one. Example: Flight Warning Computer (FWC) 1 failure. NOTE: An independent failure is displayed with the title underlined. PRIMARY FAILURE A primary failure is a failure of an item of equipment or system causing the loss of other equipment. Example: Green hydraulic system failure may lead to the loss of a pair of spoilers.U3T06191 - U0M35M0 - UM31D3000000001 NOTE: A primary failure is displayed with a box around the failure. SECONDARY FAILURE A secondary failure is a loss of an item of equipment or system resulting 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 failures are indicated on the lower right part of the Engine/Warning Display (EWD) by an asterisk.

  18. 18. SINGLE AISLE TECHNICAL TRAINING MANUAL ECAM ADVISORY & FAILURE RELATED MODES (3) ADVISORY ADVISORY MODE IN NORMAL DUAL DISPLAY The value of some critical system parameters is monitored by an advisory mode. In Electronic Centralized Aircraft Monitoring (ECAM) normal display, when a value drifts from its normal range, the corresponding system page is displayed automatically in order to attract crew attention well before reaching the warning or caution level. The affected parameter and the system page title pulse. The corresponding key light on the ECAM Control Panel (ECP) is on. Example: The CAB PRESS page will be displayed if the cabin altitude increases above its normal value, but is still well below the threshold of the warning. In this case the crew may revert to manual pressure control and prevent warning activation. NOTE: An advisory may or may not lead to a failure. They are totally independent one from the other.U3T06191 - U0M35M0 - UM31D3000000001 MAINTENANCE COURSE - M35 LINE MECHANICS ECAM ADVISORY & FAILURE RELATED MODES (3) May 10, 2006 (CFM56-5B/ME)  Page 16 31 - INDICATING/RECORDING SYSTEMS

  20. 20. SINGLE AISLE TECHNICAL TRAINING MANUAL ECAM ADVISORY & FAILURE RELATED MODES (3) ADVISORY (continued) ADVISORY MODE IN ECAM MONO DISPLAY In ECAM MONO display mode (one ECAM CRT remaining), when a value drifts from its normal range, a white ADV message flashes in the center of the EWD to attract crew attention. As the related system page cannot be displayed automatically on the System Display (SD), the pilot has to fetch the information on the ECP: the associated key light flashes to indicate which system is concerned. NOTE: The CAB PRESS system page is given as an example.U3T06191 - U0M35M0 - UM31D3000000001 MAINTENANCE COURSE - M35 LINE MECHANICS ECAM ADVISORY & FAILURE RELATED MODES (3) May 10, 2006 (CFM56-5B/ME)  Page 18 31 - INDICATING/RECORDING SYSTEMS

  22. 22. SINGLE AISLE TECHNICAL TRAINING MANUAL 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 and the actions to take. On the status and System Display (SD), the hydraulic page is called automatically. The CLeaR P/Bs come on and as long as the failure is not cleared, they stay on. On the hydraulic panel the FAULT lights come on, indicating the P/Bs to release out. NOTE: In this module, parameters are given for a CFM engine. For an IAE engine, the parameters will be shown as follows: Engine Pressure Ratio (EPR), EGT, N1 and N2). The graphics show an example of sequence of Electronic Centralized Aircraft Monitoring (ECAM) displays in case of green hydraulic system fault. This may be different to your aircraft configuration.U3T06191 - U0M35M0 - UM31P6000000001 MAINTENANCE COURSE - M35 LINE MECHANICS ECAM WARNINGS PRESENTATION (1) May 10, 2006 (CFM56-5B/ME)  Page 20 31 - INDICATING/RECORDING SYSTEMS

It is LEVEL 3 necessary to call the status page manually to see the title of the affected Level 3 corresponds to an emergency configuration. Corrective or system. palliative 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 cabinU3T06191 - U0M35M0 - UM31D3000000002 altitude), - serious system failure (Dual hydraulic failure). LEVEL 2 Level 2 agrees with an abnormal configuration. Immediate crew awareness is required, but not immediate corrective action. The crew must decide when to take the corrective action. These warnings are associated with: - Single Chime (SC), - MASTER CAUTion light amber, - warning messages on LCD.

  66. 66. SINGLE AISLE TECHNICAL TRAINING MANUAL ECAM ADVISORY & FAILURE RELATED MODES (3) TYPE OF FAILURE NOTE: This part can be used if necessary to display heading titles of warnings if the left part of the EWD is full. GENERAL The failures may be of three different types, independently of their classification. 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 FAILURE An independent failure is a failure, which affects an isolated item of equipment or system without affecting another one. Example: Flight Warning Computer (FWC) 1 failure. NOTE: An independent failure is displayed with the title underlined. PRIMARY FAILURE A primary failure is a failure of an item of equipment or system causing the loss of other equipment. Example: Green hydraulic system failure may lead to the loss of a pair of spoilers.U3T06191 - U0M35M0 - UM31D3000000002 NOTE: A primary failure is displayed with a box around the failure. SECONDARY FAILURE A secondary failure is a loss of an item of equipment or system resulting 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 failures are indicated on the lower right part of the Engine/Warning Display (EWD) by an asterisk.

SINGLE AISLE TECHNICAL TRAINING MANUAL ECAM ADVISORY & FAILURE RELATED MODES (3) ADVISORY ADVISORY MODE IN NORMAL DUAL DISPLAY The value of some critical system parameters is monitored by an advisory mode. In Electronic Centralized Aircraft Monitoring (ECAM) normal display, when a value drifts from its normal range, the corresponding system page is displayed automatically in order to attract crew attention well before reaching the warning or caution level. The affected parameter and the system page title pulse. The corresponding key light on the ECAM Control Panel (ECP) is on. Example: The CAB PRESS page will be displayed if the cabin altitude increases above its normal value, but is still well below the threshold of the warning. In this case the crew may revert to manual pressure control and prevent warning activation. NOTE: An advisory may or may not lead to a failure. They are totally independent one from the other.U3T06191 - U0M35M0 - UM31D3000000002 MAINTENANCE COURSE - M35 LINE MECHANICS ECAM ADVISORY & FAILURE RELATED MODES (3) May 10, 2006 (CFM56-5B/ME)  Page 66 31 - INDICATING/RECORDING SYSTEMS
