What must be done with the link before the flight begins?

The requirement to ensure that the link is fully charged and operational before the flight begins is critical for a number of reasons. A fully charged and operational link allows flight attendants to maintain effective communication with the cockpit and fellow crew members, which is essential for passenger safety and coordination of in-flight services. This tool may also provide access to important information, including flight details, safety procedures, and emergency protocols, all of which are vital during the course of a flight.

Ensuring the functionality of equipment like the link minimizes the risk of operational failures that could compromise the safety and efficiency of the flight. This proactive step is part of the standard operating procedures in aviation, where communication is paramount. Thus, verifying that the link is charged and working optimally addresses potential issues before they can affect the safety and service of the flight.
