How can the status page be displayed after the failure of EICAS display ED1?

The status page can be displayed after the failure of the primary EICAS display (ED1) using either of the first two options presented.

Selecting the Display Reversionary Panel to EICAS allows for the transfer of the EICAS functions to an alternate display. This feature is designed to ensure that critical flight information remains accessible to the flight crew, even if the primary display fails.

Additionally, selecting the EICAS selector on the Source Select Panel to ED2 allows the crew to access the status page via the secondary display. This redundancy is fundamental in maintaining situational awareness and operational safety, enabling vital information to be displayed through an alternative system when the primary unit is compromised.

Both methods provide the capability to visualize necessary status information, aligning with the aircraft's design to ensure operational continuity under failure scenarios. Thus, selecting either option effectively addresses the problem of a failed EICAS display.
