What defines exit row seating in aircraft?

Exit row seating in an aircraft is defined by the specific role these seats play in emergencies, particularly their proximity to emergency exits. The seats that are designated as exit row seats are positioned directly next to emergency exit doors, ensuring that passengers seated there can quickly and efficiently evacuate the aircraft in the event of an emergency.

These seats are crucial during an evacuation because they provide direct access to the exits, allowing for a swift exit. Additionally, passengers seated in these rows typically must meet specific criteria set by regulatory standards, such as being able-bodied, willing, and able to assist if evacuation procedures are necessary. This definition emphasizes the functional safety aspect of these seats rather than just comfort or luxury features, such as additional legroom or priority boarding, which do not impact their primary role related to evacuation protocols.
