What is the function of the Digital Map Set?

• A. Part of the Tactical Aircraft Moving Map Capability (TAMMAC) system.
• B. Provides real-time collision avoidance advisories.
• C. Sends flight data to ground stations.
• D. Stores weather data for predictive weather routing.

Answer: (A)

The Digital Map Set provides the map data that the Tactical Aircraft Moving Map Capability uses. In other words, it’s the digital database of maps—terrain, airspace, obstacles, navigation features—that feeds the cockpit’s moving-map display so pilots can see their position relative to the world and plan or monitor routes with context. This data is what TAMMAC uses to render the map on the flight displays and support navigation and situational awareness.

Other systems handle different tasks: collision advisories come from the collision-awareness systems, not the map set; transmitting flight data to ground stations is a data-link function separate from the map database; and storing weather data for predictive routing comes from weather data services, not the digital map set.
