What is the primary purpose of the Alerting Service provided by ATS units?

The primary purpose of the Alerting Service provided by Air Traffic Service (ATS) units is to notify safety services about aircraft needing assistance. This service is vital in ensuring the safety of pilots and passengers, as it allows for rapid communication and coordination in emergency situations. If an aircraft is in distress or unresponsive, the alerting service can quickly notify relevant authorities, such as search and rescue teams, to respond effectively. This function is particularly crucial in scenarios where time is of the essence, and immediate action is necessary to ensure the safety of those on board.

While controlling air traffic using radar systems is important, it primarily focuses on traffic flow rather than emergency response. Managing fuel efficiency is related to operational performance but does not fall under the purview of the alerting service. Coordinating logistics between airports pertains more to ground operations and does not directly involve the safety and emergency protocols embedded in the alerting service framework.
