A lever and a placard beside an aircraft door showing armed and disarmed positions.
Also known as: Slide armed marking, Doors to automatic marking, Girt bar marking
The marking beside an aircraft cabin door shows two positions for the arming lever: armed and disarmed. Armed connects the evacuation slide to the door, so that opening it deploys the slide automatically; disarmed disconnects it, so the door opens as an ordinary door. This is what the cabin announcement 'doors to automatic' refers to. Deploying a slide by mistake at a stand is expensive and dangerous, which is why the marking is large, colour-coded and cross-checked between crew.

Is cross-checked between crew members rather than trusted to one person, because an inadvertent slide deployment at a stand injures ground staff and takes the aircraft out of service.
