Multifunction Display Management
There are a total of five MFDs available at any one time on the flight deck.
However, five displays of the same MFD cannot be shown at the same time. If a
display is currently shown, additional instances are managed in one of three ways:
• Synchronized – a copy of an instance that is already displayed. Any change
on one instance affects all other instances of that display.
• Independent – not linked to any other instance on the flight deck. Can be
changed without affecting or being affected by other instances of that
display.
• Blank – when the selected display exceeds the maximum number of
instances allowed, an existing instance of that display becomes blank with
a message “SELECT MFD.” Additional pilot selection is required to
replace the blank display with another display, unless the default display
for that location is not already shown.
The maximum number of instances each display format may be shown are:
• SYS (2 per side, independent)
• CDU (1 per side, independent)
• INFO (2 per side, independent)
• CHKL (1 per side, synchronized)
• COMM (1 per side, independent)
• ND (1 per side, independent)
EFIS Control Panels
The EFIS control panels control display options, mode, and range for the
respective PFDs and NDs.
For additional information, refer to:
• Primary Flight Displays (PFDs)
, Ch. 10, Sec. 30
• Navigation Displays
, Ch. 10, Sec. 40
If an EFIS control panel fails, the displays can be controlled through the backup
EFIS/DSP display on the SYS page. The backup EFIS capability is available at all
times, but inhibits inputs from the respective EFIS control panel.
The EFIS Control Panel controls any on-side ND display. Both pilots have access
to the lower DU. However, whichever pilot chooses first to display the ND on the
lower DU owns the ND when the other pilot chooses to display an ND on the other
half of the lower DU. This results in a full-display ND on the lower DU which the
first pilot controls.
