In radio communications, what does Hailing refer to?

• A. Distress call
• B. Urgency signal
• C. Securite
• D. Calling/general communication

Answer: (D)

Hailing is the process of initiating radio contact to establish two-way communication with another station. It’s the general call used to attract attention and start a conversation, before exchanging the actual message. This is why the best answer is the calling/general communication option—it captures the idea of making a broad initial contact.

Distress calls (Mayday) are for grave danger and have a specific format. An urgency signal (Pan-Pan) indicates an urgent situation but not imminent danger. Securite is a safety message used to broadcast navigational or meteorological safety information. Hailing, by contrast, is simply the initial general call to establish contact. In practice, you’d typically hail on the designated calling channel (for example, on VHF channel 16) to announce who you are and request to communicate, then move to a working channel once contact is established.
