(1) DISPLAY SWITCHING for SPZ-8000 equipped airplanes is
accomplished by three (3) selector knobs: PILOT, EICAS and
COPILOT.
If either PFD fails, selecting PFD XFER with the associated
DISPLAY SWITCHING knob moves the PFD display to the ND. If an
ND fails, ND OFF is selected.
If either the Engine Instruments (EI) display or the Crew Alerting
System (CAS) display fails, the remaining operating display can
provide a compacted presentation of both displays. Selection of the
EICAS DISPLAY SWITCHING knob to TOP CMPT presents all
information on the EI display; selection to BOT CMPT presents all
information on the CAS display.
(2) DISPLAY SWITCHING for SPZ-8400 equipped airplanes is
accomplished automatically by the central warning system in the
following manner:
• Failure of either PFD switches that PFD to the associated ND
• Failure of either ND shuts off that ND
• Failure of the EI display causes all of EICAS to be displayed
compacted on the CAS display
• Failure of the CAS display causes all of EICAS to be
displayed compacted on the EI display
Manual switching provisions are incorporated to override the
automatic switching feature through the use of two (2) selector
knobs: PILOT and COPILOT. Manual switching is also required to

restore normal operation after automatic switching has taken place.
Note that manual switching only affects DU 2 and DU 5. The
available manual selections are described as follows.
(a) PILOT Selector:
• NORM - normal presentation
• PFD - displays PFD information on DU 2
• ENG / EICAS - with DU 3 failed, EI data is displayed
on DU 2
(b) COPILOT Selector:
• NORM - normal presentation
• PFD - display of PFD information on DU 5
• CAS / EICAS - with DU 4 inoperative, normal CAS
data is displayed on DU 5
(3) SYMBOL GENERATOR CONTROL for both SPZ-8000 and SPZ-
8400 equipped airplanes provides three (3) selectors: PILOT,
EICAS and COPILOT. Each selector provides reversionary control
of its associated SG, as shown in Figure 18 and Figure 19 and
summarized in the following table:

H. Electronic Checklist:
Electronic checklist modules are installed in the fault warning computers of
all SPZ-8400 equipped airplanes, in SPZ-8000 equipped airplanes SN
1144 and subsequent, and in SPZ-8000 equipped airplanes SN 1000
through 1143 having ASC 178 incorporated. The checklist is controlled with
either the ND joystick and associated switches (Figure 16) or the display
controller.
The electronic checklist can be displayed with the ND in the MAP, COMP or
PLAN mode. When displayed, it appears in the lower center portion of the
ND. The electronic checklist has the following features:
• 12 lines of text per checklist page (maximum)

• Display for NORMAL, ABNORMAL and EMERGENCY procedures
(EMERGENCY procedures normally displayed on copilot’s ND only)
• Automatic display (auto-callup) of EMERGENCY procedures
(normally displayed on copilot’s ND only)
When selected by the display controller, the electronic checklist is
displayed on the on-side ND. A typical checklist is composed of data
generated by the selected fault warning computer and contains the
following:
• Label (NORMAL/ABNORMAL/EMERGENCY)
• Cursor
• Procedure title
• Procedure page index
• Procedure step description
The electronic checklist can be selected by only one display controller at a
time. Once selected by one display controller, the checklist is displayed on
the on-side ND and the ability to select the checklist for display is removed
from the cross-side display controller.
The title page of the electronic checklist (labeled TITLE PAGE) is the first
item displayed in the NORMAL index. The TITLE PAGE must be reviewed
by the flight crew before any other selection on the NORMAL, ABNORMAL
or EMERGENCY index can be made. For the emergency procedures
