Which item is not a step in the exit door arming procedure?

The reason "Pull" is not a step in the exit door arming procedure is that the arming process does not typically involve a pulling action. Arming an exit door generally entails securing it in a manner that ensures it cannot be opened in emergency situations until it is disarmed, which is essential for passenger safety. This process includes inserting the pin, moving the lever to the appropriate position, and securing any straps as needed to maintain the integrity of the door's status.

The steps associated with arming typically involve engaging mechanisms that physically secure the door rather than pulling, which might imply an action that would disengage or open the door. Understanding the precise steps in the arming procedure is crucial for ensuring that cabin crew can effectively manage the doors during boarding and deplaning, significantly impacting passenger safety.
