After the failure of EICAS display ED1, how can the status page be displayed?

• A. Select display reversionary panel to EICAS
• B. Selected EICAS selector on the source panel to ED2
• C. Both A and B
• D. No action will display the status page

Answer: (C)

When a primary EICAS display (ED1) fails, you still need access to EICAS information, so the system can route EICAS data to the remaining good display. The two ways shown both accomplish this routing: using the display reversionary panel to select EICAS, or using the EICAS source selector on the source panel to display EICAS on ED2. In either case, ED2 will show the EICAS status page, letting you view system status and faults despite ED1 being out of service. Since there are valid methods to bring up the status page on the remaining display, choosing both options together is correct.
