Which statement about the door arming and disarming procedures is true?

• A. The door streamer should be placed across the door viewing window during arming
• B. Door streamer is placed across the door viewing window during disarming
• C. The Velcro patch over the manual inflation handle should be hidden during arming
• D. Crosschecking is not required for 1L and 1R

Answer: (A)

Arming a door relies on a clear, visual status cue that the slide is ready for deployment. Placing the door streamer across the door viewing window during arming provides an immediate, unambiguous indication to all crew that the door has been armed. This quick visual check supports safe operations by making the armed condition obvious at a glance and during crosschecks with the other crew member. When disarming, the streamer is removed, not left in place, to reflect the door is no longer armed. The Velcro patch over the manual inflation handle should remain accessible and not be hidden, since the inflation system and its controls must be visible and usable. Crosschecking is performed to confirm status, including for the front doors, so it isn’t correct to say it isn’t required for those exits.
