Which MC controls do what?

• A. MC2 Navigation; MC1 Mission Accomplishment
• B. MC1 Mission Accomplishment; MC2 Navigation
• C. MC2 Mission Accomplishment; MC1 Navigation
• D. MC1 Navigation; MC2 Mission Accomplishment

Answer: (D)

The idea being tested is how a dual Mission Computer setup assigns distinct responsibilities to each unit to improve reliability and fault isolation. In this arrangement, one computer handles navigation and guidance, while the other focuses on mission accomplishment tasks such as sequencing, payload control, and mission execution. The best mapping assigns MC1 to Navigation and MC2 to Mission Accomplishment. This keeps the navigation pathway independent from the mission execution pathway, so a fault in one does not directly compromise the other. It also follows a clear division of duties, which is how the system is designed to operate safely and reliably. Placing Navigation with MC2 or Mission Accomplishment with MC1 would blur responsibilities and reduce fault isolation, making the system more vulnerable if one computer encounters a fault or anomaly.
