What are the two types of computer memory cards used with the DMD?

• A. Mission PC Card and Maintenance/Map PC Card
• B. Flight Card and Ground Card
• C. Theater Card and Mission Card
• D. Data Card and Memory Card

Answer: (A)

The DMD uses two PC Card style memory modules to keep different kinds of data separate and easily updatable. The Mission PC Card stores mission-specific data the crew loads for a particular operation—things like mission libraries, flight profiles, EW parameters, and targeting data that the DMD uses during flight. The Maintenance/Map PC Card holds maintenance information and map data—the navigation maps and system calibration or diagnostic data that ground crews update and store for upkeep of the aircraft’s systems. Keeping these data sets on distinct cards helps prevent data from one area interfering with the other, makes updates safer and more straightforward, and mirrors how the DMD organizes its data. Other card names don’t match how the system actually labels and uses the memory modules.
