ENGINE INDICATING AND CREW ALERTING SYSTEM (EICAS)
DESCRIPTION
The function of the EICAS is to display the engine instruments and give visual and aural crew-alert messages and real time
interpretation of aircraft system operation.
Most EICAS information is normally displayed on the left and right multifunction displays (MFDs). Some display infor-
mation is shown by default, other information is available through selection. The top half of the left MFD normally displays
engine indications (EI) on the left, aircraft configuration (gear, flaps, spoilers, trim) in the middle, and Crew Alerting Sys-
tem (CAS) messages on the right. The top half of the right MFD normally displays the summary synoptic page, but the
electronic crew checklist can be selected. Maintenance diagnostic information can also be displayed in this area by main-
tenance personnel. The bottom half of both MFDs can display navigation information or system synoptic pages as selected
by the crew. Control of displayed information is provided by the MFD control panel (MCP) located on the center pedestal.
A composite flight instrument/EICAS can be displayed in the event of display failure. Select PFD Rev or MFD Rev on the
Reversion panel to access these displays. The FRMT button on the display control panel is used to select the SUMMARY
synoptic page for display when PFD REV is selected on the reversion panel. The summary synoptic is only available when
an on-side display is reverted.
Engine indications are provided on the left MFD. Color is used to depict normal (green), non-normal (amber or red) and
loss of data (magenta).
The crew alerting system (CAS) provides visual and aural alerts when the data concentrator units (DCUs) detect a malfunc-
tion. The CAS prioritizes messages by order of order of importance and order of occurrence.
The order of importance of messages is accomplished by the use of color displays and aural alerts.
EICAS COLOR LOGIC AND SYNOPTIC PAGE PRESENTATION
The Challenger 300 uses a Quiet Dark Cockpit Philosophy for system indications.
Cockpit indications remain quiet and dark during the following:
- Normal operation (no abnormalities or failures)
- Daylight
- Visual meteorological conditions (VMC)
- Non-icing conditions
- Cruise flight
Color Logic is used to depict system values:
- Red — Warning condition or system limit exceeded
- Amber — Component or function failed or there is no flow, energy or pressure
- Green — Normal operation for digital values. Normal flow, energy or pressure in flowlines
- White — Normal status of component (pump, valve, etc.) or no flow through the flowline
- Magenta — Invalid or unknown data
