In a conventional ADI, which component displays the Flight Director Bar?

• A. Flight Director Computer
• B. Flight Director Indicator
• C. Attitude Indicator
• D. Horizontal Situation Indicator

Answer: (A)

In a conventional ADI, the guidance you see as the Flight Director Bar comes from the Flight Director Computer. This computer processes pilot inputs and navigation/auto-pilot commands to generate the commanded pitch and bank cues. Those cues are then displayed on the attitude indicator as the Flight Director Bar, telling you how to maneuver the aircraft to follow the desired flight path. The attitude indicator provides the visual surface, but the actual cues—the bar you read for pitch and roll—originate from the flight director computer. The other devices either serve as the display surface for attitude, or provide separate navigation information, but they do not generate the flight director cues.
