Which color indicates a 'selected' FMA mode when armed?

• A. Magenta
• B. Green
• C. Blue
• D. White

Answer: (C)

On the Flight Mode Annunciator, colors show the status of each mode. When you select a mode and arm it for engagement, it appears in blue. This blue coloring signals that the mode is chosen and ready to become active once the conditions allow. Once the mode actually becomes active and starts guiding the aircraft, the color changes to white. The other colors indicate different states or transitions, but they do not represent the “selected/armed” status. So blue is the color that flags a mode as selected and armed.
