If the cabin crew hears "NITS no 1 received", what should N1 do next?

In an aviation context, when cabin crew members receive a communication like "NITS no 1 received," it indicates the need for acknowledgment of the message. Repeating back the information ensures clarity and understanding between crew members regarding the operational status or instructions being conveyed.

Synchronized watches can be crucial for coordination during various phases of flight, particularly for emergency procedures, briefings, or time-sensitive tasks. By repeating the message, cabin crew maintain situational awareness and confirm that all individuals are on the same page regarding their responsibilities and the flight's status.

Other options, while they may pertain to other phases of flight or tasks, do not directly relate to the immediate importance of acknowledging and clarifying received messages, which is essential for effective crew communication and safety.
