A PFDU failure will result in _________.

A PFDU failure will result in _________.

• A. The PFD automatically appears on the respective ND.
• B. The PFD automatically disappears from all displays.
• C. The ND switches to PFD off mode.
• D. The PFD moves to the ECAM display.

Answer: (A)

When a PFDU fails, the system automatically reroutes the PFD data to the same side’s ND. This keeps the essential flight information—attitude, airspeed, altitude, flight cues—visible to the pilot even though the PFD unit has failed. The ND remains active, now presenting what would normally be on the PFD, so you don’t lose critical information. The other possibilities would imply losing the PFD entirely, turning the ND off, or moving the PFD data to the ECAM page, none of which aligns with how the display redundancy is designed.
