What is the primary focus area for the No4 to check after a ditching?

The primary focus area for the No4 after a ditching is typically the front rows of the aircraft, specifically Rows 1-10. This area is crucial because it is often where passengers can be most vulnerable, and it is also the primary evac zone for everyone onboard, especially in situations that may require rapid response and ensuring passenger safety.

Rows 1-10 are significant in the context of evacuation scenarios since they are closest to exits. In a ditching event, quick access to these exits can be vital for the safety of all onboard. The duties of the No4 involve ensuring that these areas are cleared quickly, assessing the condition of passengers, and providing guidance toward the exits for safe evacuation. The focus here aligns with the importance of securing the cabin and aiding passengers effectively during emergencies, particularly in a ditching scenario where time is of the essence.
