After the initial MCDU power-up, where can the remaining steps be accomplished?

• A. Only on the flight deck MCDU
• B. Only on the MSO consoles
• C. From either the MCDU or virtual MCDU at the MSO consoles
• D. Not required to perform remaining steps

Answer: (C)

The remaining steps after the initial MCDU power-up can be performed from either the physical MCDU on the flight deck or the virtual MCDU available at the MSO consoles. This mirrors how the system is built to allow initialization and configuration to continue from a cockpit interface or a remote, replicated interface at the Mission System Operator station. The virtual MCDU at the MSO consoles provides the same prompts and entry points, so the team can complete the necessary steps without needing to be in the cockpit. This dual-access setup offers redundancy and operational flexibility, ensuring progress can continue even if one interface isn’t available.
