Who has control of Vu2 if the CIU fails?

• A. Front Seater
• B. Pilot
• C. Copilot
• D. Back Seater

Answer: (D)

When a central control unit like the CIU fails, the aircraft must still be controllable through a path that doesn’t rely on that unit. In Vu2’s two-seat setup, the back seater is equipped with a direct or secondary control path that bypasses the CIU, allowing manual control of the controls and surfaces to continue functioning. This design ensures that flight can be maintained even when the primary interface goes down.

The front seater and the pilot's inputs typically ride through the CIU to reach the control surfaces; with the CIU out, those inputs may not be processed correctly, so they aren’t the reliable source of control in this failure scenario. The back seater, having the independent bypass, is therefore the person who maintains control when the CIU fails.
