In emergency evacuation procedures, which action follows inserting the left hand in the assist handle?

Following the insertion of the left hand into the assist handle during emergency evacuation procedures, the correct action is to quickly bring the operating handle upward. This step is crucial because bringing the operating handle upwards is necessary to unlock and open the emergency exit door. By executing this action promptly, crew members can facilitate a swift evacuation, ensuring that passengers can exit the aircraft safely and efficiently in an emergency situation.

The procedure emphasizes speed and decisiveness, which are essential in maintaining safety in emergencies. Quickly raising the operating handle helps avoid any delay that could put passengers at risk. Other actions, while relevant in the overall evacuation process, do not immediately follow the insertion of the hand into the assist handle as effectively as raising the handle does. For instance, assessing the cabin or pushing the MCD (Main Cabin Door) inward might occur as part of the overall evacuation strategy but are secondary to the primary goal of opening the door to allow exit.
