Display Select Panel
The display select panels (one for each pilot) on the glareshield provide control of
the MFDs for the on-side inboard DU. Each DU has a left and right window. The
currently selected MFD window (left or right) is indicated by the illuminated
annunciator light above the corresponding display switch (L or R).
After a display unit is selected, the appropriate display is selected (SYS, CDU,
INFO, CHKL, COMM, or ND). The ENG switch toggles the display of secondary
engine formation on the EICAS display. The EICAS transfer switch toggles the
EICAS display between the inboard half of the Captain and First Officer inboard
DUs.
Each pilot also has a display select panel next to the lower display unit. These
DSPs provide each pilot control of their half of the lower DU. This allows the
selection of the same MFDs as on the upper DUs. However, these DSPs do not
include the ENG, CANC/RCL, or EICAS transfer switches.
Display select panel control is also available through the backup EFIS/DSP
display on the SYS page. This capability is available at all times. The DSP
hardware controls remain active when the EFIS backup is enabled if the DSP is
still functional. Any available MFD window may be selected.
Display Brightness Control
The MASTER BRIGHTNESS control provides simultaneous brightness
adjustment for all displays and panel lighting. Also, each display unit has an
individual control with limited range control when master brightness is on, and
full range control when master brightness is off.
Two remote light sensors, located left and right on the top of the glareshield,
measure brightness in the forward field of view and adjust the overall display
brightness as required. Individual sensors on the front of each display unit also
affect display brightness. The EFBs, mode control panel displays, standby flight
instruments, and aisle stand panel displays are also controlled by the automatic
display brightness control system.
PFD/MFD Source Selector
The PFD/MFD selector is used to switch displays if there is undetected display
unit failure.
When the selector is in the inboard position (INBD DU), the outboard display unit
is blanked and the inboard display unit shows the cropped PFD and EICAS if
EICAS was previously displayed on this side. Otherwise, whichever display that
was shown in place of EICAS before the failure is shown.
