Which aspect is NOT part of the expedited deplaning procedure?

The correct choice highlights an important aspect of the expedited deplaning procedure. The procedure is designed to allow passengers to exit the aircraft quickly and safely in emergency situations, which means that there are certain limitations on the actions passengers can take during this process.

Retrieving personal items goes against the fundamental purpose of expedited deplaning, as it can lead to delays and hinder the quick evacuation of passengers. In emergencies, the priority is to get everyone off the aircraft safely and efficiently, rather than stopping to collect belongings that can impede that goal.

In contrast, using the Main Cabin Door exclusively, leaving belongings on the aircraft, and even having emergency lighting are parts of the expedited procedure that facilitate an orderly evacuation. These measures ensure that the focus remains on getting passengers out of the aircraft as quickly and safely as possible without the interference of personal items or other distractions.
