Arming a door is a safety-sensitive change that affects whether the door can be opened during an evacuation. Because this status change can impact crew and passenger actions, it’s important to announce what’s about to happen before you arm the door. The pre-arming announcement gives everyone time to ensure the area around the exit is clear, that passengers are seated with seat belts fastened, and that no one near the door attempts to operate it as the mechanism is engaged. If you arm the door without informing people first, it can lead to confusion or unsafe attempts to use the door at the wrong time. So the appropriate moment is to make the arm door announcement before arming the door. Boarding or arrival aren’t the right times for this handoff, since arming is a pre-departure security step performed on the ground.
