How many main ship batteries exist on the Citation Longitude?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Redundancy in the aircraft electrical system ensures essential power remains available when something stops working. The Citation Longitude is designed with two main ship batteries so critical DC power can be preserved even if one battery or its circuit has a fault. Each battery feeds its own power path to the essential electrical buses, and a battery-bus tie capability lets one battery back up the other if needed. This setup provides continuous operation for important systems like flight instruments, radios, and controls during start, taxi, and flight, while avoiding the weight and complexity of extra batteries. So the design uses two main ship batteries to balance reliability with efficiency.
