If one MC fails, what does the other MC take over?

• A. Mission Accomplishment
• B. Both Functions
• C. Navigation
• D. None

Answer: (C)

This item tests how redundancy works in a dual mission computer setup. If one computer fails, the remaining mission computer takes over navigation responsibilities to keep guidance and attitude updates running. Navigation is the critical path that must stay active for safe operation, so the design routes control to the surviving unit for that role. The other options don’t fit because mission accomplishment isn’t a separate transferable function in this context, none would leave a missing critical capability, and taking over all tasks (both functions) isn’t how this failover is described.
