What is a possible consequence of not addressing a PANPAN situation promptly?

In a PANPAN situation, which indicates a state of urgency but not an immediate threat to life, failing to address it promptly can lead to serious consequences. One critical outcome is that the situation may escalate into a mayday scenario, where there's an imminent danger to life or safety. This escalation typically occurs when the underlying issues—such as mechanical problems or navigational challenges—are not resolved quickly. The initial warning of PANPAN serves to alert both air traffic control and other aircraft of a developing situation that requires attention; if these signals are disregarded or not acted upon swiftly, it can lead to critical situations that necessitate immediate emergency action. Hence, neglecting a PANPAN can significantly increase the risk to the aircraft and its passengers, potentially putting everyone on board in jeopardy.
