Where does the STS reminder flash when the STATUS page holds a Class 2 message after engine shut-down?

When a Class 2 message is retained on the STATUS page after engine shutdown, the STS reminder will indeed flash on the E/WD (Engine/Warning Display) screen. This feature is designed to alert the crew of any important status messages that require attention even after the engines are turned off, underscoring the continuous monitoring capabilities of the aircraft's systems.

The E/WD screen is critical in displaying essential flight data and alerts concerning engine performance and system status. When the STS reminder activates, it allows the crew to address any outstanding notifications related to aircraft status and maintenance needs promptly, ensuring safety and operational readiness before the next flight or maintenance digression.

Other displays, like the Upper DU or Lower DU, serve different functions and may not be directly responsible for flashing reminders of status messages after engine shutdown. The Maintenance Panel, while providing essential maintenance information, does not flash alerts in the manner described, focusing instead on static data regarding the aircraft's maintenance requirements and indications.
