Electronic Centralized Aircraft Monitoring (ECAM)

Event Record Switch

• Normally, an auto event function records malfunctions automatically
• The push switch enables manual event marking for storing suspect malfunctions in non-volatile memory
• Retrieved data can be displayed by ground engineers using the ground maintenance panel
• Manual switch can also be used to record fault data in the air or on the ground for Environmental Control, Electrical Power, Hydraulic, and APU systems

Computer Select Switch

• In the "AUTO" position, it selects the primary computer and switches to the other in case of failure
• Other positions allow manual selection of either the right or left computers

Display Brightness

• Controlled by inner knob for display intensity and outer knob for display brightness

Thrust Reference Set Switch

• Pulling and rotating the inner knob positions the reference cursor on the thrust indicator display (EPR or N1) for selected engines
• Engine selection is done by the outer knob

Max Indicator Reset

• Alerts are displayed on display units if measured parameters exceed normal operating limits
• The reset button clears alerts from the display when excess limits no longer exist

STATUS MODE

• Displays data to determine dispatch readiness of an aircraft
• Closely associated with the aircraft's Minimum Equipment List
• Displays positions of flight control surfaces, selected sub-system parameters, and equipment status messages on the lower display unit
• Normally selected on the ground for pre-flight checks or prior to shutdown to aid in making entries in the aircraft's Technical log

MAINTENANCE MODE

• Provides maintenance engineers with information in five different display formats to aid in fault finding and verification testing of major sub-systems

DISPLAY SELECT PANEL

• Controls the operation of EICAS
• Located on the centre pedestal

EICAS Control Panel

• Engine Display Switch: a push-type switch for removing or presenting secondary information on the lower display
• Status Display Switch: a push-type switch for removing or presenting the status page on the lower display

DISPLAY UNITS

• Provide a wide variety of information relevant to engine operation and automated systems
• Upper unit displays primary engine parameters, warning and caution messages
• Lower unit displays secondary parameters, non-engine system status, and other information

DISPLAY MODES

• EICAS categorizes displays and alerts according to function and usage
• Three modes of displaying information: Operational, Status, and Maintenance

OPERATIONAL MODE

• Displays engine operating information and alerts required to be actioned by the crew in flight
• Normally, only the upper display unit presents information

ECAM (Electronic Centralized Aircraft Monitoring)

• Differs from EICAS in that displayed data relates to primary systems of the aircraft
• Data displayed in checklist and pictorial or synoptic format

ECAM DISPLAY UNITS

• Can be mounted either side-by-side or top/bottom
• Left-hand/top unit displays system status, warnings, and corrective action in a sequenced checklist format
• Right-hand/bottom unit displays associated information in pictorial or synoptic format

ECAM DISPLAY MODES

• Four display modes: three automatically selected (phase-related, advisory, and failure-related) and one manual mode
• Manual mode permits selection of diagrams related to 12 aircraft systems for routine checking and selection of status messages

Flight Phase Related Mode

• Automatically selected based on current phase of aircraft operation
• Displays appropriate to the current phase of aircraft operation (pre-flight, take-off, climb, cruise, descent, approach, and post landing)

STS Switch

• Permits manual selection of an aircraft's status message if no warning is displayed
• Illuminates white when pressed and also illuminates the CLR switch

RCL Switch

• Enables previously cleared warning messages to be recalled if failure conditions still exist
• Pressing this switch also illuminates the CLR switch
• If failure no longer exists, "NO WARNING PRESENT" is displayed on the left-hand display unit
