Which service is responsible for alerting search and rescue authorities when an aircraft is in distress?

• A. Terminal Radar Service
• B. Aircraft Movement Information Service
• C. Alerting Service
• D. Airspace Reservation Service

Answer: (C)

Alerting the appropriate rescue authorities when an aircraft is in distress is the function of the Alerting Service. This service monitors for distress situations and, upon detection or a pilot’s Mayday declaration, notifies the relevant Search and Rescue authorities and coordinating centers, then coordinates the initial search and rescue response and ongoing liaison until the aircraft is located or a safe conclusion is reached. It uses information from various ATS sources, such as last known position and flight status, to trigger timely SAR action. The other services have different roles: Terminal Radar Service provides radar-based traffic advisories and sequencing in the terminal area; Aircraft Movement Information Service offers information about aircraft movements to improve safety; Airspace Reservation Service manages areas of airspace that are temporarily restricted for events or activities. None of these are primarily responsible for initiating distress alerts to SAR authorities.
