Which crew member seat is designated for N1 during take-off and landing?

During take-off and landing, the designated crew member seat for N1 is the L1 jump-seat outboard. This position is crucial as it provides the crew member with an optimal line of sight to both the cabin and the flight deck during critical phases of flight. The N1 crew member, typically the first officer or another designated crew role, is responsible for monitoring cabin conditions and ensuring passenger safety. The outboard location allows for better visibility outside the aircraft, which is essential for performing safety checks and coordinating with the flight deck during these important moments.

Additionally, standard operating procedures dictate specific locations for crew member seating during take-off and landing to enhance crew readiness and passenger safety, making the L1 jump-seat outboard a vital part of the aircraft's safety protocols. The other choices do not align with this requirement, as they either place the crew member in an alternative position that does not adhere to the standard protocol or do not offer the necessary visibility and access to the cabin or flight deck.
