When should the caution strap be used?

• A. Door is closed and latched
• B. Door is open and unattended, with no jet-bridge or stairs at the open door
• C. During boarding only
• D. When the aircraft is in motion

Answer: (B)

The safety concept here is about marking and controlling the doorway area when the door is open but not actively attended and no boarding equipment is in place. When a door is open and unattended, and there’s no jet bridge or stairs attached, people could accidentally approach the open door or equipment could block the doorway. Placing the caution strap creates a visible boundary that reminds crew and ground personnel to stay clear of the opening and to secure the area until boarding or deplaning is completed or until a bridge/stairs is brought to the door. If the door is closed and latched, there’s no open doorway to hazard, so the strap isn’t needed. If a jet bridge or stairs are in place, the doorway area is already protected by the equipment and procedures, and motion of the aircraft would require everyone to be clear of the door area anyway. Hence this strap is specifically for the scenario of an open, unattended door without boarding equipment.
