During the "No.1 to the Flight Deck" procedure, what must No.1 do first?

In the "No.1 to the Flight Deck" procedure, the primary responsibility of No.1, who is typically the lead cabin crew member, is to ensure effective communication with the flight deck. By picking up the phone and announcing their status, No.1 initiates a crucial part of the procedure that signals readiness to proceed. This communication establishes contact with the flight crew and confirms that the cabin crew is prepared to assist, ensuring that everyone is aligned in the process.

This step is vital as it not only maintains safety protocols but also allows the flight crew to be aware of the cabin conditions and readiness before they transition into the cockpit. By establishing this communication first, No.1 effectively coordinates the next steps in the procedure, such as assessing cabin conditions, securing all cabin crew stations, or waiting for further instructions, which can follow after this initial announcement.
