What areas does the N4 check after evacuation?

The N4 check after evacuation is focused on ensuring the safety and security of the aircraft by conducting a thorough inspection of the first ten rows. This procedure is critical because it allows the crew to verify that all passengers have exited safely and that no one remains on board who might require assistance. The first ten rows are prioritized typically because they often include the closest seats to the exits, making them crucial in emergency situations.

By inspecting these rows, the crew can also assess whether there are any potential hazards within the cabin, such as remaining luggage that could obstruct the cabin or pose risks during an emergency response. This systematic approach ensures that the cabin is clear of individuals and any tripping or safety hazards before further actions, such as allowing reboarding or coordination with emergency services, can take place. Therefore, the focus on rows one through ten aligns with best practices for evacuation procedures.
