Components
EICAS includes those components that receive, process and display information. The EICAS
components also provide audio signals to the audio system for voice and aural annunciations and
operating and flight parameter data to the flight data recorder. Major components and controls
include:
• Four adaptive flight displays;
• Two data concentrator units;
• One lamp driver unit;
• Two cursor control panels;
• One reversionary control panel;
• Two master warning/caution switch/lights;
• One audio warning panel; and
• One miscellaneous test panel.

Adaptive Flight Displays
The four liquid-crystal adaptive flight displays (AFDs) are used as part of the electronic flight
instrument (EFIS) and EICAS systems. The outer AFDs are normally configured as primary
flight displays (PFDs) while the inner AFDs are configured as multifunction displays (MFDs).
EICAS information is normally presented on the left MFD, however, it can also be displayed on
the right MFD. Under certain conditions the EICAS information can also be presented on the
PFDs.

Data Concentrator Units
The aircraft is equipped with two independently operating data concentrator units (DCUs). The
DCUs, located in the avionics compartment, contain the processing software required for the
operation of the adaptive flight displays. The AFDs render EICAS displays based on inputs from
the DCUs. The software also contains the equations that define the crew alerting function of the
EICAS. These crew alerting functions include the voice and aural tones and annunciations
produced by the audio system.
The DCUs process flight and operating parameter data for transfer and storage to the flight data
recorder. The DCUs also process and transfer fault data for the maintenance diagnostic
computer.
The DCUs receive information from the major systems and subsystems including:
• Bleed Air;
• Air conditioning;
• Ice and Rain;
• Electrical Power;
• Fire Protection;
• Flight Controls;
• Fuel;
• Hydraulics;
• Landing Gear;
• Lights;

• Oxygen;
• Engine;
• Auxiliary Power Unit;
• Doors; and
• Avionic Systems.
Lamp Driver Unit
The dual-channel lamp driver unit (LDU) is used to power individual panel and glareshield lights
when commanded by the data concentrator units. When the DCU generates an EICAS warning
or caution message, the LDU causes the glareshield MASTER WARNING/CAUTION
switch/lights to flash, and turns on any associated panel lights.
Cursor Control Panel
Each pilot is provided with a cursor control panel (CCP), located on the center pedestal. Each
CCP is the pilot’s main interface to control information presented on the on-side MFD.
The CCP can be divided into 5 functional and visually identifiable sections as described below:
• MFD window formatting – allows selection of navigation formats, display and control of
on-screen menus and to enable overlays;
• Memory keys – allows the crew to save specific display formats to memory for quick
access;
• Chart control – displays charts from the optional chart system;
• EICAS control – enables the display of synoptic, SUMMARY pages and controls the
display of crew alerting messages; and
• Radio tuning – controls communications and navigation radio tuning.
