Who is responsible for holding passengers back during an evacuation from seat 3A?

The correct choice reflects the standard protocol during an evacuation scenario. An Able Bodied Person (ABP) at seat 3A would be in the best position to assist with crowd control and passenger management directly at that exit point. This individual is closest to the emergency exit and can respond immediately to any instructions given by the flight crew or take appropriate action to facilitate an orderly evacuation.

Having an ABP at 3A hold passengers back is crucial for ensuring that other passengers are not hindered when exiting through the designated emergency exit. This helps prevent bottlenecks and keeps the evacuation route clear, which is essential for safety. An ABP is typically someone who is willing to assist and is capable of following instructions based on the training provided to them.

In contrast, the roles of a Flight Attendant or ABPs located at different seats are less effective in this particular task, as their distances from the emergency exit limit their ability to control the flow of passengers effectively at that critical moment. Their focus may be better directed towards managing other exit points or ensuring that safety protocols are followed elsewhere in the cabin.
