Which action should be performed to ensure the door handle is secure during arming?

• A. Verify the door operating handle is fully rotated, ensuring the door is closed and locked
• B. Ensure the door streamer is in place before any other step
• C. Remove the girt bar from the floor brackets
• D. Crosscheck 1L and 1R after arming

Answer: (A)

When arming a door, the key action is to rotate the door operating handle fully to the armed position and verify it’s in that position. This provides a positive confirmation that the door is closed, locked, and the evacuation slide is properly armed. If the handle isn’t fully rotated, the door may not be securely armed, which can compromise safety during an evacuation.

The other steps aren’t placed at the heart of arming: the streamer isn’t part of the arming action, removing the girt bar would defeat arming, and crosschecking 1L and 1R after arming doesn’t verify the door’s armed state itself.
