What does a Mayday call signify?

A Mayday call is a standard distress signal used in maritime and aviation communication to indicate a life-threatening emergency. When a vessel or aircraft issues a Mayday call, it signifies that the situation is critical and immediate assistance is required. This type of call alerts coast guards, rescue services, and any nearby vessels or aircraft that there is a serious emergency, such as a sinking ship, a crew member overboard, or other life-threatening circumstances.

It's important to understand that this call is internationally recognized and must be given priority by all communications to ensure a rapid response. The urgency of a Mayday call distinguishes it from other types of communication, such as routine messages or requests for assistance related to weather updates or navigation issues, which do not carry the same level of urgency or immediacy.
