Which term indicates the percentage of not mission capable time that should be minimized?

• A. NMCS
• B. NMCT
• C. NMCD
• D. NMC

Answer: (B)

Not Mission Capable Time is the percentage of total operating time during which an aircraft is not able to perform its assigned missions. This metric should be minimized because it directly reflects downtime and overall readiness; lowering NMCT increases the availability of aircraft for missions. It accounts for downtime from any cause, giving a single, actionable measure of how often assets are not ready. The other terms focus on specific causes—Not Mission Capable Supply covers downtime due to parts shortages, and Not Mission Capable Maintenance covers downtime caused by maintenance actions—so they don’t represent the overall proportion of time not available for missions.
