Which statement about the timing of the white box around an active FMA mode is true?

• A. 5 seconds
• B. 10 seconds
• C. 15 seconds
• D. 20 seconds

Answer: (B)

When a mode becomes active, the cockpit’s display uses a temporary highlight to draw attention to that change. The white box around the active FMA mode stays in place for 10 seconds, providing a clear, brief confirmation during exciting or busy moments. If another mode is captured during that window, the highlight shifts to the new mode and the 10-second timer restarts. After the 10 seconds, the box disappears, but the mode remains active and shown in the FMA. So the defined timing for that visual cue is 10 seconds.
