Radio Communications (RCOM) Practice Test

Who has control of Vu1 if the CIU fails?

Pilot Copilot Front Seater Crew Chief

Correct Answer:

Front Seater

Explanation:

When a central cockpit interface unit fails, the system is designed to hand control of essential cockpit displays to the person in the primary flight position—the front seater. This is the crew member who sits at the primary flight controls and has the authority and capability to operate or override cockpit displays manually. In this fail condition, the front seater assumes control of the Vu1 to maintain safe operation. The copilot does not automatically take over Vu1 in this scenario, the crew chief is a maintenance role and not responsible for operating flight displays in flight.
