What should you pull after deploying the emergency slide?

After deploying the emergency slide, it is crucial to pull the red manual handle. This action is vital because the red manual handle is specifically designed to ensure the slide is properly inflated and secured for use during an emergency evacuation. When the emergency slide is deployed, it functions as a critical means of exiting the aircraft quickly and efficiently. Pulling the red manual handle activates the inflation mechanism, ensuring the slide is operational and safe for passengers and crew to use.

The other choices do not serve the same function in this specific context. The green assist handle may be used for other emergencies but does not relate directly to the deployment process. The safety strap typically provides a secondary function in ensuring safety during the use of the slide but does not aid in its deployment or inflation. The exit pin is usually related to securing the door in a closed position and is not involved in the emergency slide process. Therefore, understanding the role of the red manual handle is essential for effective emergency procedures on the aircraft.
