What does "PAN PAN" indicate in radiotelephony?

"PAN PAN" is a radiotelephony term used to convey an urgent safety concern that requires attention but does not signify a life-threatening emergency. This term serves as an intermediate level of urgency in aviation communications. When a pilot or operator broadcasts "PAN PAN," it indicates that there is a situation that may need assistance or intervention, but it is not critical enough to justify a full emergency declaration, which would use the term "MAYDAY."

The distinction between "PAN PAN" and "MAYDAY" is significant in emergency management; "PAN PAN" alerts others that the speaker's situation is urgent, allowing for coordinated responses without creating undue alarm. As a result, this assists in prioritizing communications and responses among air traffic control and other aircraft. Understanding this terminology is crucial for effective communication in aviation scenarios where safety and proper response protocols are paramount.
