When the MANUAL light on the auto/manual door status indicator is illuminated, what does that indicate about the doors?

• A. All doors are armed
• B. One door out of sync
• C. All doors are disarmed
• D. Auto/manual both off

Answer: (C)

The auto/manual door status indicator shows whether the escape slides are armed for automatic operation or not. When the MANUAL light is illuminated, the system is in manual mode, meaning the door slides are not armed and all doors are disarmed. In this state, opening a door would not deploy a slide automatically, which is why this indicator signals disarmed doors. If doors were armed, you’d see the AUTO indication; a door out of sync would trigger a different warning rather than the MANUAL light alone.
