When can caution messages can be paged and boxed?

• A. Paged on the ground with the engines shut down
• B. Boxed with both engines at stabilized idle
• C. Boxing in flight is a function of WOW
• D. All of the above

Answer: (D)

Caution messages are designed to be accessible and managed across multiple operating states, so you can page through and box them whenever needed. On the ground with engines shut down, you can page and box cautions to review system status during preflight or maintenance, even with no power to the engines. With both engines at stabilized idle, the cockpit alerting remains active, so paging and boxing help you monitor cautions during run-up or taxi checks without relying on full thrust. In flight, the caution system still supports paging and boxing, with the logic sometimes tied to conditions like weight-on-wheels or other state indicators, to keep alerts readable without overwhelming the crew. Because this capability applies in all these situations, paging and boxing cautions is possible across these states.
