What communication protocol should be followed after a Mayday is declared?

When a Mayday is declared, the appropriate communication protocol involves moving all communication to the alternate tactical channel. This ensures that the urgent nature of the Mayday is prioritized, allowing for clear and uninterrupted communication between the crew members involved in the emergency situation.

In such scenarios, it's essential that normal operational traffic does not interfere with the critical communication regarding the emergency, which could potentially detract from the safety of those in distress. By utilizing a designated alternate channel, fire personnel can focus on coordinating a prompt and effective response without the clutter of routine radio chatter.

This approach helps maintain situational awareness for both the personnel responding to the emergency and those monitoring the radio communications, ultimately improving the chances of a successful rescue or intervention.
