In what mode can the MFD replicate the PFD information?

• A. Standard mode
• B. Essential mode
• C. Backup mode
• D. Emergency mode

Answer: (B)

The Multi-Function Display (MFD) can replicate the Primary Flight Display (PFD) information in Essential mode. This mode is specifically designed to prioritize critical flight data when the primary systems are compromised. In Essential mode, the MFD presents vital information such as attitude, altitude, airspeed, and heading, which is crucial for maintaining situational awareness during flight. This capability ensures that pilots can continue to access necessary flight data even if the PFD fails or becomes unavailable, thereby enhancing safety and operational effectiveness.

The other modes serve different purposes and may not provide the same level of replication of PFD information that is essential for flying the aircraft safely in all operational conditions.
