What is the position of No.4 during the safety demonstration?

The position of No.4 during the safety demonstration is indeed at Row 1. In the context of an aircraft, the crew members are typically assigned specific locations for conducting safety demonstrations to ensure that all passengers can see and hear the instructions clearly. Row 1, being at the front of the cabin, allows the crew member to utilize their position effectively, as it is often one of the first seating areas passengers encounter when boarding the aircraft.

This strategic placement helps in maximizing visibility and ensuring that important safety information is delivered efficiently to all passengers. It also allows for easy access to any passengers that may require additional assistance or attention. The other mentioned rows are further back in the cabin, which may not serve the same purpose in terms of visibility and engagement during the demonstration.
