Which indicator color is associated with showing that a door is armed for most doors except 3L/3R?

• A. Yellow
• B. Green
• C. Red
• D. Blue

Answer: (A)

Indicator color communicates the door’s arming status. For the majority of doors, when armed, the indicator shows yellow, giving a quick, visible cue that the slide is in the armed configuration and ready to deploy when the door is opened in the correct direction. The 3L/3R doors use a different arming indicator system, so their status is not shown by yellow. This color cue lets crew verify arming status at a glance during preflight and in moments of need, helping ensure the cabin is prepared for departure and for emergencies.
