What does DNC stand for when talking about the MSS?

• A. Digital Nautical Chart
• B. Data Network Console
• C. Dynamic Nautical Chart
• D. Direct Nautical Command

Answer: (A)

DNC stands for Digital Nautical Chart. In mission systems, this is the electronic, machine-readable version of a traditional navigational chart used for display, planning, and situational awareness. It supports layered information (depths, hazards, aids to navigation), can be updated from hydrographic authorities, and integrates with sensors and routing tools to help crew make informed decisions. The other terms aren’t standard in this context—Data Network Console describes a hardware interface, while Dynamic Nautical Chart and Direct Nautical Command aren’t established terms for navigational chart data in MSS.
