What does the auto/manual status light indicate?

• A. It indicates whether the doors are armed or disarmed
• B. It indicates cabin temperature
• C. It indicates interphone status
• D. It indicates oxygen flow

Answer: (A)

The auto/manual status light is tied to the door arming system. It shows the mode that governs how the passenger doors’ escape slides are controlled and, in effect, confirms the door’s arming state. When the light indicates auto, the system manages arming automatically as you close and configure the door during normal ops; when it indicates manual, the crew must control arming/disarming directly. In either case, the indicator is about whether the doors are armed or disarmed for evacuation, not about cabin temperature, interphone status, or oxygen flow.
