Which EFIS component is responsible for allowing the pilot to select the appropriate system configuration for the current flight situation?

• A. CRT
• B. Symbol generator
• C. Display controller
• D. Ground safety switch

Answer: (C)

The part that lets the pilot choose the right display setup for the current flight situation is the display controller. It acts as the command center for the EFIS displays, taking pilot inputs (mode or configuration selections) and coordinating how data is shown on the screens. It decides which information appears where (PFD, MFD, navigation display, maps, weather overlays, etc.) and how it’s formatted to match the flight phase or actions being performed. The CRT is simply the actual screen, showing whatever the controller and symbol generator produce. The symbol generator creates the graphical symbols that appear on the screens, but it relies on the display controller to determine what to display. The ground safety switch is a safety interlock and doesn’t manage EFIS configuration.
