When should the extension seatbelts be considered for use?

The correct choice emphasizes the importance of ensuring safety for specific groups of passengers who may not fit standard seatbelt configurations. Extension seatbelts are designed to accommodate infants and oversize passengers, allowing them to be safely secured during flight. This is critical because standard seatbelts might not provide a secure fit, which could compromise safety during turbulence or in the event of an emergency.

Understanding when to use extension seatbelts is crucial for flight safety protocols. Infants may require a different means of restraint, such as being secured in a parent's lap or a special infant seat, while oversize passengers may need additional belt length to ensure they are properly restrained. By considering these factors, airlines meet regulatory requirements and enhance passenger safety.

While other choices highlight specific conditions, they do not encompass the broader scope necessary for passenger safety as effectively as the correct answer does.
