# Center/Control Display Unit (CDU)

The Osprey is equipped with one Control Display Unit (CDU), located on the center console, between the pilot and copilot. It features a large LCD Display, surrounded by a bezel containing switches and push buttons. The top left rotary know controls the screen brightness mode (OFF, DAY, NIGHT). The CDU also features two keyboards, located just underneath the display, for data entry.
