What data does the DMD communicate with the mission computer system to record?

• A. Maintenance code history, fatigue strain gage, engine and technical data
• B. Crew schedules
• C. Fuel consumption
• D. GPS coordinates

Answer: (A)

The data being recorded by the DMD and sent to the mission computer are maintenance code history, fatigue strain gage data, and engine/technical data. This set gives a complete picture of the aircraft’s condition: maintenance codes show what work was done or needed, fatigue strain data reveals structural loading and potential life-limit concerns, and engine/technical data provide real-time performance and health indicators for the propulsion and related systems. Together, they support diagnostics, trend analysis, and maintenance planning by the mission computer. Data like crew schedules, fuel consumption, or GPS coordinates come from different systems and purposes and aren’t the data the DMD is designed to feed into the mission computer for recording.
