What does the urgency signal indicate?

The urgency signal is specifically designed to convey a very urgent message concerning safety. This signal alerts other stations that the situation at hand requires immediate attention, but it is less critical than a distress signal. By indicating that the message relates to safety, it prompts those who receive it to prioritize the message and respond appropriately while still maintaining a level of caution. The urgency signal serves as a means to ensure that essential information related to the safety of flights or passengers is communicated effectively without causing alarm that would accompany a distress call.
