What is the correct action to take after sending a distress alert via Inmarsat-C by mistake?

The correct action after mistakenly sending a distress alert via Inmarsat-C is to select "Transmit" to send a cancellation message. In the context of maritime communication, it is crucial to address any accidental distress signals promptly to avoid causing confusion or unnecessary responses from search and rescue authorities.

When a distress alert is sent unintentionally, immediate action helps clarify the situation to the Rescue Coordination Center (RCC) and prevents the mobilization of emergency resources that could disrupt actual operations. Sending a cancellation message formally communicates that the distress alert was a mistake, providing clarity and ensuring that communication channels remain clear for genuine emergencies.

It is important to follow the established protocol in such situations, as handling them properly maintains the integrity of maritime safety communication systems and helps ensure that help is available for those who genuinely need it.
