When the lower Display Unit (DU) fails on the A320, the aircraft's systems are designed to automatically display a desired systems page on the upper DU. The duration for which this page remains visible is specifically set to ensure that pilots have adequate time to reference critical information during a failure scenario. The correct answer, which is a duration of 2 minutes, reflects the operating procedures and safety standards that facilitate effective monitoring and management of the aircraft’s systems while maintaining a focus on flying the aircraft.

This time limit provides pilots with enough opportunity to assess the situation without overwhelming them with excessive information, as they may need to switch their focus back to primary flight tasks or troubleshoot the failure. Other durations, such as 1 minute, 3 minutes, and 4 minutes, do not align with the designed operational limits outlined in the A320 systems training, emphasizing the importance of adhering to set timelines that are optimized for pilot workload management.
