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)

The key check during arming is to verify the door operating handle is fully rotated to the locked position, ensuring the door is closed and the latch is engaged. This is the direct, physical confirmation that the door is securely latched before arming, so the door cannot open in flight and the slide will deploy correctly if needed. If the handle isn’t rotated fully, the latch may not be engaged even if the door appears closed, leaving the door unsecured. The other steps described aren’t as directly tied to confirming the door’s secure latch status: the streamer is a status aid, removing the girt bar would defeat arming, and crosschecking left and right doors is a separate verification after arming rather than the action that guarantees the handle’s secure position during arming.
