2026 Auxiliary Officer and Electrical Division Core Exam Practice Test

CMAV is a planned in-port maintenance period where work is performed in a continuous sequence over a defined window. The idea is to run a steady flow of maintenance tasks for several weeks while the unit is in-port, typically about 4–6 weeks, with a cadence of once per quarter. This setup allows many tasks to be completed in one sustained effort, coordinating multiple trades and minimizing overall downtime.

A single maintenance event lasting one week isn’t continuous and doesn’t cover the longer window CMAV uses. Intermittent maintenance with no fixed period lacks the scheduled, steady flow and cadence CMAV requires. Maintenance every month regardless of port status ignores the in-port condition and the defined 4–6 week duration and quarterly cadence. Therefore, the description that best fits CMAV characteristics is a continuous flow of maintenance lasting 4–6 weeks, once per quarter when in-port.
