What color is used to display the engaged vertical and lateral modes of the FMA?

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

Answer: (B)

The engaged vertical and lateral modes of the Flight Mode Annunciator (FMA) are displayed in green. This color is used to indicate that the autopilot is actively controlling the aircraft in those respective modes. The green indication provides clear and immediate confirmation to the pilots that the system is functioning as intended and that the selected modes are currently active. This color-coding helps pilots quickly assess the aircraft's operational state, enhancing situational awareness during flight. Understanding the color usage on the FMA is critical for proper cockpit management and ensuring that pilots can efficiently monitor autopilot status and respond if necessary.
