When fueling and the number of passengers is less than 150, where should the N4 be positioned?

When the number of passengers is less than 150, positioning the N4 on board is essential for maintaining safety and ensuring proper emergency procedures. The N4 is a document that serves as a reference for crew and involves critical information related to passenger management during fueling, particularly in situations where a significant number of passengers might pose safety risks.

Having the N4 on board allows the crew to have immediate access to that information, enabling them to act efficiently and appropriately should any circumstances arise during the refueling process. Situating the N4 in an easily accessible location ensures that the crew can quickly reference it, reducing potential communication delays or confusion that could arise if the document were located elsewhere, such as in the terminal or at the boarding gate.

Other choices may not provide the same immediacy or ease of access required for effective safety management during fueling operations, reinforcing the need for the N4 to remain on board in this scenario.
