Urgency message

An urgency message is a radiotelephony message used when an aircraft, another vehicle, or a person is facing a serious problem that needs priority, but is not in immediate danger requiring a distress call. It is introduced by the urgency signal Pan Pan, spoken three times. Pilots use it to report the situation, their intentions, and any assistance needed. After transmitting it, they listen carefully, follow ATC instructions, and keep frequency use clear and concise.
