If one MC fails, the other automatically takes over which function?

• A. Data Link operations
• B. Weather data processing
• C. Weapon release commands
• D. Control of the navigation

Answer: (D)

Redundancy with automatic switchover aims to keep navigation control uninterrupted. In a dual mission computer setup, navigation control is the function designed to automatically hand off to the backup computer if the primary unit fails. This ensures the aircraft retains a continuous, reliable source of guidance for the flight path, autopilot, and flight management systems, which is critical for safe operation. Other functions like data link operations, weather data processing, and weapon release commands don’t typically require automatic transference between mission computers in the same failover manner. Data link and weather data can have separate redundant pathways or sources and aren’t always tied to immediate flight safety in the same seamless way. Weapon release commands are safety-critical and usually require explicit human confirmation or interlocks, so automatic takeover isn’t used for that function.
