Study Notes

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

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
