Which control can be used to transfer the navigation display to the ND when needed?

• A. ND XFR pushbutton
• B. MCDU
• C. ECAM control panel
• D. RMP knob

Answer: (A)

The function being tested is the ability to move or share the navigation information between the two ND displays using a dedicated transfer control. The ND XFR pushbutton is specifically for transferring the navigation display from one ND to the other, so you can bring the ND image to the side you need or show it to the other crew member as required. Other controls have different roles: the MCDU handles route input and flight management, not display transfer; the ECAM control panel manages system status and alerts; and the RMP knob tunes radios. So for transferring what you see on the navigation display, the ND XFR pushbutton is the correct and best choice.
