If the center MFD (PFD) fails, the PFD reverts to the right MFD and replaces the EICAS, NAV display remains as is.

• A. False
• B. True
• C. Not enough information
• D. N/A

Answer: (A)

Redundancy and display management in a glass cockpit determine how information reflows when a display fails. If the center PFD/MFD goes down, the system doesn’t automatically move the PFD to the right-hand unit and replace the EICAS there while leaving the NAV page untouched. Engine data (EICAS) and flight data (PFD) are separate streams, and the flight deck typically reconfigures to preserve essential information by either duplicating the remaining PFD on the other display, moving EICAS to an available screen, or showing a fault on the failed unit. The NAV page can also be affected by the new layout, so assuming it stays exactly as is isn’t correct. Therefore the statement is not correct.
