Element 1 (MROP)

What is the internationally recognized Urgency signal?

Explanation
The internationally recognized Urgency signal is "PAN PAN," spoken three times before the urgency call. This radiotelephony signal indicates that the transmitting station has a very urgent message concerning the safety of a ship, aircraft, or person, but does not require immediate assistance. It signifies a lower level of severity than a distress call. A) "TTT" transmitted three times is the internationally recognized urgency signal for radiotelegraphy (Morse code), not radiotelephony. C) Three oral repetitions of the word “Safety” is not a recognized signal. The international safety signal for radiotelephony is "SECURITE" (pronounced Say-cure-e-tay), repeated three times. D) The pronouncement of the word "Mayday" is the internationally recognized *distress* signal, indicating grave and imminent danger requiring immediate assistance, which is distinct from an urgency situation.
