When the ECP is inhibited following ED failure, what happens to the status and synoptic pages?

• A. They are removed.
• B. They continue to display.
• C. They are redirected to ED3.
• D. They switch to a backup set.

Answer: (A)

When the Emergency Control Panel is inhibited after an ED failure, the status and synoptic pages are removed from the display. This prevents pilots from seeing outdated or invalid information about a subsystem that’s no longer functioning, avoiding confusion or incorrect actions. Since the ECP is inhibited, the system won’t continue to show those pages, redirect to another page, or switch to a backup set—the unreliable data source has been effectively taken offline, so the related displays are cleared.
